6520fe5564 x86, realmode: 16-bit real-mode code support for relocs tool
A new option is added to the relocs tool called '--realmode'.
This option causes the generation of 16-bit segment relocations
and 32-bit linear relocations for the real-mode code. When
the real-mode code is moved to the low-memory during kernel
initialization, these relocation entries can be used to
relocate the code properly.

In the assembly code 16-bit segment relocations must be relative
to the 'real_mode_seg' absolute symbol. Linear relocations must be
relative to a symbol prefixed with 'pa_'.

16-bit segment relocation is used to load cs:ip in 16-bit code.
Linear relocations are used in the 32-bit code for relocatable
data references. They are declared in the linker script of the
real-mode code.

The relocs tool is moved to arch/x86/tools/relocs.c, and added new
target archscripts that can be used to build scripts needed building
an architecture.  be compiled before building the arch/x86 tree.

[ hpa: accelerating this because it detects invalid absolute
  relocations, a serious bug in binutils 2.22.52.0.x which currently
  produces bad kernels. ]

bb8187d35f MCA: delete all remaining traces of microchannel bus support.
Hardware with MCA bus is limited to 386 and 486 class machines
that are now 20+ years old and typically with less than 32MB
of memory.  A quick search on the internet, and you see that
even the MCA hobbyist/enthusiast community has lost interest
in the early 2000 era and never really even moved ahead from
the 2.4 kernels to the 2.6 series.

This deletes anything remaining related to CONFIG_MCA from core
kernel code and from the x86 architecture.  There is no point in
carrying this any further into the future.

One complication to watch for is inadvertently scooping up
stuff relating to machine check, since there is overlap in
the TLA name space (e.g. arch/x86/boot/mca.c).

d6686da814 scripts/config: properly report and set string options
Currently, scripts/config removes the leading double-quote from
string options, but leaves the trailing double-quote.

Also, double-quotes in a string are escaped, but scripts/config
does not unescape those when printing

Finally, scripts/config does not escape double-quotes when setting
string options.

Eg. the current behavior:
    $ grep -E '^CONFIG_FOO=' .config
    CONFIG_FOO="Bar \"Buz\" Meh"
    $ ./scripts/config -s FOO
    Bar \"Buz\" Meh"
    $ ./scripts/config --set-str FOO 'Alpha "Bravo" Charlie'
    $ grep -E '^CONFIG_FOO=' .config
    CONFIG_FOO="Alpha "Bravo" Charlie"

Fix those three, giving this new behavior:
    $ grep -E '^CONFIG_FOO=' .config
    CONFIG_FOO="Bar \"Buz\" Meh"
    $ ./scripts/config -s FOO
    Bar "Buz" Meh
    $ ./scripts/config --set-str FOO 'Alpha "Bravo" Charlie'
    $ grep -E '^CONFIG_FOO=' .config
    CONFIG_FOO="Alpha \"Bravo\" Charlie"

9f420bf0f4 kbuild: all{no,yes,mod,def,rand}config only read files when instructed to.
Prevent subtle surprises to both people working on the kconfig code
and people using make allnoconfig allyesconfig allmoconfig and
randconfig by only attempting to read a config file if
KCONFIG_ALLCONFIG is set.

Common sense suggests attempting to read the extra config files does
not make sense unless requested.  The documentation says the code
won't attempt to read the extra config files unless requested.
Current usage does not appear to include people depending on the code
reading the config files without the variable being set So do the
simple thing and stop reading config files when passed
all{no,yes,mod,def,rand}config unless KCONFIG_ALLCONFIG environment
variable is set.

1f2bfbd00e kbuild: link of vmlinux moved to a script
Move the final link of vmlinux to a script to improve
readability and maintainability of the code.

The Makefile fragments used to link vmlinux has over the
years seen far too many changes and the logic had become
hard to follow.

As the process by nature is serialized there was
nothing gained including this in the Makefile.

"um" has special link requirments - and the
only way to handle this was to hard-code the linking
of "um" in the script.
This was better than trying to modularize it only for the
benefit of "um" anyway.

The shell script has been improved after input from:

5efe241eac kconfig: Add error handling to KCONFIG_ALLCONFIG
- Only try to read the file specified if KCONFIG_ALL_CONFIG is set to
  something other than the empty string or "1".

- Don't use stat to check the name passed to conf_read_simple so that
  zconf_fopen can find the file in the current directory or in SRCTREE
  removing a extremely source of confusing failure, where KCONFIG_ALL_CONFIG
  was not interpreted with respect to the directory make was called in.

- If conf_read_simple fails complain clearly and stop processing.
  Allowing the simple debugging of typos.

- Clearly document the behavior so it is clear to users which
  values are treated as flags and which values are treated as
  filenames.

7431fb767d HID: Allow bus wildcard matching
Most HID drivers do not need to know what bus driver is in use.
A generic group driver can drive any hid device, and the device
list should not need to be duplicated for each new bus.

This patch adds wildcard matching to the HID bus, simplifying device
list handling for group drivers.

4d53b8012f HID: Add device group to modalias
HID devices are only partially presented to userland.  Hotplugged
devices emit events containing a modalias based on the basic bus,
vendor and product entities. However, in practise a hid device can
depend on details such as a single usb interface or a particular item
in a report descriptor.

This patch adds a device group to the hid device id, and broadcasts it
using uevent and the device modalias.  The module alias generation is
modified to match. As a consequence, a device with a non-zero group
will be processed by the corresponding group driver instead of by the
generic hid driver.

d59a16836d scripts/sortextable: Handle relative entries, and other cleanups
x86 is now using relative rather than absolute addresses in its
exception table, so we add a sorter for these.  If there are
relocations on the __ex_table section, they are redundant and probably
incorrect after the sort, so they are zeroed out leaving them valid
and consistent.

Also use the unaligned safe accessors from tools/{be,le}_byteshift.h

0db7bd8ca0 xz: Enable BCJ filters on SPARC and 32-bit x86
The BCJ filters were meant to be enabled already on these
archs, but the xz_wrap.sh script was buggy. Enabling the
filters should give smaller kernel images.

xz_wrap.sh will now use $SRCARCH instead of $ARCH to detect
the architecture. That way it doesn't need to care about the
subarchs (like i386 vs. x86_64) since the BCJ filters don't
care either.

e88aa7bbbe Fix modpost failures in fedora 17
The symbol table on x86-64 starts to have entries that have names
like:

_GLOBAL__sub_I_65535_0___mod_x86cpu_device_table

They are of type STT_FUNCTION and this one had a length of 18.  This
matched the device ID validation logic and it barfed because the
length did not meet the device type's criteria.

--------------------
FATAL: arch/x86/crypto/aesni-intel: sizeof(struct x86cpu_device_id)=16 is not a modulo of the size of section __mod_x86cpu_device_table=18.
Fix definition of struct x86cpu_device_id in mod_devicetable.h
--------------------

These are some kind of compiler tool internal stuff being emitted and
not something we want to inspect in modpost's device ID table
validation code.

So skip the symbol if it is not of type STT_OBJECT.

258f742635 modpost: Fix modpost license checking of vmlinux.o
Commit f02e8a6596 ("module: Sort exported symbols") sorts symbols
placing each of them in its own elf section.  This sorting and merging
into the canonical sections are done by the linker.

Unfortunately modpost to generate Module.symvers file parses vmlinux.o
(which is not linked yet) and all modules object files (which aren't
linked yet).  These aren't sanitized by the linker yet.  That breaks
modpost that can't detect license properly for modules.

This patch makes modpost aware of the new exported symbols structure.

[ This above is a slightly corrected version of the explanation of the
  problem, copied from commit 62a2635610 ("modpost: Fix modpost's
  license checking V3").  That commit fixed the problem for module
  object files, but not for vmlinux.o.  This patch fixes modpost for
  vmlinux.o. ]

7f3bd6c9cb setlocalversion: Use "grep -q" instead of piping output to "read dummy"
In some circumstances (eg when running a build in an emacs shell
buffer), I get a spew of messages like

    grep: writing output: Broken pipe

from setlocalversion, because the "read" subshell apparently exits as
soon as it reads one line and gives EPIPE to grep.  It's not clear to
me why this way of writing the check was used instead of just using
grep -q to suppress output, but unless there is some deep reason I
don't know, this way looks cleaner to me anyway, and gets rid of the
ugly message spew.

(I double checked at http://pubs.opengroup.org/onlinepubs/009604499/utilities/grep.html
and "grep -q" is specified in POSIX / SuS, so hopefully even people
cross-compiling the kernel on some bizarre host OS can't complain
about this change)

875de98623 scripts/Kbuild.include: Fix portability problem of "echo -e"
"echo -e" is a GNU extension. When cross-compiling the kernel on a
BSD-like operating system (Mac OS X in my case), this doesn't work.

One could install a GNU version of echo, put that in the $PATH before
the system echo and use "/usr/bin/env echo", but the solution with
printf is simpler.

Since it is no disadvantage on Linux, I hope that gets accepted even if
cross-compiling the Linux kernel on another Unix operating system is
quite a rare use case.

ca56dc098c checkpatch: check for quoted strings broken across lines
checkpatch already makes an exception to the 80-column rule for quoted
strings, and Documentation/CodingStyle recommends not splitting quoted
strings across lines, because it breaks the ability to grep for the
string.  Rather than just permitting this, actively warn about quoted
strings split across lines.

Test case:

void context(void)
{
	struct { unsigned magic; const char *strdata; } foo[] = {
		{ 42, "these strings"
		      "do not produce warnings" },
		{ 256, "though perhaps"
		       "they should" },
	};
	pr_err("this string"
	       " should produce a warning\n");
	pr_err("this multi-line string\n"
	       "should not produce a warning\n");
	asm ("this asm\n\t"
	     "should not produce a warning");
}

Results of checkpatch on that test case:

WARNING: quoted string split across lines
+	       " should produce a warning\n");

total: 0 errors, 1 warnings, 15 lines checked

6e2e340b59 ARM: 7324/1: modpost: Fix section warnings for ARM for many compilers
It turns out that many compilers don't show section warnings on ARM
currently because handling for ARM_CALL relocs are missing from
modpost.c.

Based on commit c2e26114 ([ARM] 3205/1: Handle new EABI relocations when
loading kernel modules) it seems that R_ARM_PC24, R_ARM_CALL and
R_ARM_JUMP24 can be handled the same way.

Note that at least Debian libc6-dev is missing defines for both
R_ARM_CALL and R_ARM_JUMP24 in /usr/include/elf.h. So for now
we need to define them in modpost.c if not defined.

644e9cbbe3 Add driver auto probing for x86 features v4
There's a growing number of drivers that support a specific x86 feature
or CPU.  Currently loading these drivers currently on a generic
distribution requires various driver specific hacks and it often
doesn't work.

This patch adds auto probing for drivers based on the x86 cpuid
information, in particular based on vendor/family/model number
and also based on CPUID feature bits.

For example a common issue is not loading the SSE 4.2 accelerated
CRC module: this can significantly lower the performance of BTRFS
which relies on fast CRC.

Another issue is loading the right CPUFREQ driver for the current CPU.
Currently distributions often try all all possible driver until
one sticks, which is not really a good way to do this.

It works with existing udev without any changes. The code
exports the x86 information as a generic string in sysfs
that can be matched by udev's pattern matching.

This scheme does not support numeric ranges, so if you want to
handle e.g. ranges of model numbers they have to be encoded
in ASCII or simply all models or families listed. Fixing
that would require changing udev.

Another issue is that udev will happily load all drivers that match,
there is currently no nice way to stop a specific driver from
being loaded if it's not needed (e.g. if you don't need fast CRC)
But there are not that many cpu specific drivers around and they're
all not that bloated, so this isn't a particularly serious issue.

Originally this patch added the modalias to the normal cpu
sysdevs. However sysdevs don't have all the infrastructure
needed for udev, so it couldn't really autoload drivers.
This patch instead adds the CPU modaliases to the cpuid devices,
which are real devices with full support for udev. This implies
that the cpuid driver has to be loaded to use this.

This patch just adds infrastructure, some driver conversions
in followups.

Thanks to Kay for helping with some sysfs magic.

v2: Constifcation, some updates
v4: (trenn@suse.de):
    - Use kzalloc instead of kmalloc to terminate modalias buffer
    - Use uppercase hex values to match correctly against hex values containing
      letters

5d09598d48 kconfig: fix new choices being skipped upon config update
Running `oldconfig' after any of the following configuration change:

either trivial addition, such as:

config A
	bool "A"

choice
	prompt "Choice ?"
	depends on A

	config CHOICE_B
		bool "Choice B"

	config CHOICE_C
		bool "Choice C"
endchoice

or more tricky change:

OLD KCONFIG                      |  NEW KCONFIG
                                 |
                                 |  config A
                                 |          bool "A"
                                 |
choice                           |  choice
        prompt "Choice ?"        |          prompt "Choice ?"
                                 |
        config CHOICE_C          |          config CHOICE_C
                bool "Choice C"  |                  bool "Choice C"
                                 |
        config CHOICE_D          |          config CHOICE_D
                bool "Choice D"  |                  bool "Choice D"
endchoice                        |
                                 |          config CHOICE_E
                                 |                  bool "Choice E"
                                 |                  depends on A
                                 |  endchoice

will not cause the choice to be considered as NEW, and thus not be
asked. The cause of this behavior is that choice's novelty are computed
statically right after the saved configuration has been read. At this
point, the new dependency's value is still unknown and asserted to be
`no'. Moreover, no update to this decision is made afterward.

Correct this by dynamically evaluating a choice's novelty, and removing the
static evaluation.

620c231c7a kbuild: do not check for ancient modutils tools
scripts/depmod.sh checks for the output of '-V' expecting that it has
module-init-tools in it. It's a hack to prevent users from using
modutils instead of module-init-tools, that only works with 2.4.x
kernels. This however prints an annoying warning for kmod tool, that is
currently replacing module-init-tools.

Rather than putting another check for kmod's version, just remove it
since users of 2.4.x kernel are unlikely to upgrade to 3.x, and if they
do, let depmod fail in that case because they should know what they are
doing.

65f2e753f1 Revert "ARM: sa11x0: Implement autoloading of codec and codec pdata for mcp bus."
This reverts commit 5dd7bf59e0.

Conflicts:

	scripts/mod/file2alias.c

This change is wrong on many levels.  First and foremost, it causes a
regression.  On boot on Assabet, which this patch gives a codec id of
'ucb1x00', it gives:

	ucb1x00 ID not found: 1005

0x1005 is a valid ID for the UCB1300 device.

Secondly, this patch is way over the top in terms of complexity.  The
only device which has been seen to be connected with this MCP code is
the UCB1x00 (UCB1200, UCB1300 etc) devices, and they all use the same
driver.  Adding a match table, requiring the codec string to match the
hardware ID read out of the ID register, etc is completely over the top
when we can just read the hardware ID register.

37ae2d5998 kbuild: Fix compiler warning with assertion when calling 'fwrite'
Reinhard Tartler discovered a corner case of calling xfwrite() where the
length of the string is zero.

Arnaud Lacombe suggested to use assertion for the corner case, as
fwrite(3) is currently used:

 1) in comment printers. Empty comment are not allowed.
 2) in a callback passed to expr_print(), where the string printed is
    either NULL OR non-empty.
 3) in the lexer, auto-generated, and unused.

I feel using assertion is a good solution:

 1) It cleanly takes care of the above-mentioned corner case.
 2) It can be easily disabled by defining NDEBUG.
 3) It asserts xfwrite() is simply a wrapper for fwrite().

Thus, for example, "make dtbs" will rebuild tegra-harmony.dtb if only
tegra20.dtsi has changed yet tegra-harmony.dts has not. The previous

For ARM, it's obvious what to add to $(targets). I'm not familiar enough
with other architectures to know what to add there. Powerpc appears to
already add various .dtb files into $(targets), but the other archs may
need something added to $(targets) to work.

4b5f72145e kconfig: add merge_config.sh script
After noticing almost every distro has their own method of managing config
fragments, I went looking at some best practices, and wanted to try to
consolidate some of the different approaches so this fairly simple
infrastructure can be shared (and new distros/build systems don't have to
implement yet another config fragment merge script).

This script is most influenced by the Windriver tools used in the Yocto
Project, reusing some portions found there.

This script merges multiple config fragments, warning on any overridden
values.  It then sets any unspecified values to their default, then
finally checks to make sure no specified value was dropped due to
unsatisfied dependencies.

I'm sure this implementation won't work for everyone, and I expect it will
need to evolve to adapt for various use cases.  But I think its a
reasonable starting point.

364212fdda kconfig/streamline-config.pl: Fix parsing Makefile with variables
Thomas Lange reported that when he did a 'make localmodconfig', his
config was missing the brcmsmac driver, even though he had the module
loaded.

Looking into this, I found the file:
drivers/net/wireless/brcm80211/brcmsmac/Makefile
had the following in the Makefile:

MODULEPFX := brcmsmac

obj-$(CONFIG_BRCMSMAC)  += $(MODULEPFX).o

The way streamline-config.pl works, is parsing all the
 obj-$(CONFIG_FOO) += foo.o
lines to find that CONFIG_FOO belongs to the module foo.ko.

But in this case, the brcmsmac.o was not used, but a variable in its place.

By changing streamline-config.pl to remember defined variables in Makefiles
and substituting them when they are used in the obj-X lines, allows
Thomas (and others) to have their brcmsmac module stay configured
when it is loaded and running "make localmodconfig".

Fix up type and cast spacing checks such that all occurences on a line are
examined and reported.  For example the line below has a valid cast and a
bad type, but currently we check the cast first which is good and stop:

    u16* bar = (u16 *)baz;

We will also only report one of the errors in this example:

    u16* bar = (u16*)bad;

Move to iterating across all casts and all types, reporting any failure.

ed128fea3b get_maintainers.pl: follow renames when looking up commit signers
I happen to have had a commit to various network drivers since the big
renaming/reorg which happened to drivers/net recently.  This means that I
now appear to be in the top few commit signers (by %age) for many of them
so am getting sent all sorts of stuff and people who are involved with the
driver are not.  e.g.  (to pick one at random):

        $ ./scripts/get_maintainer.pl -f drivers/net/ethernet/nvidia/forcedeth.c
        "David S. Miller" <davem@davemloft.net> (commit_signer:5/7=71%)

2e885057b7 recordmcount: Fix handling of elf64 big-endian objects.
In ELF64, the sh_flags field is 64-bits wide.  recordmcount was
erroneously treating it as a 32-bit wide field.  For little endian
objects this works because the flags of interest (SHF_EXECINSTR)
reside in the lower 32 bits of the word, and you get the same result
with either a 32-bit or 64-bit read.  Big endian objects on the
other hand do not work at all with this error.

The fix:  Correctly treat sh_flags as 64-bits wide in elf64 objects.

The symptom I observed was that my
__start_mcount_loc..__stop_mcount_loc was empty even though ftrace
function tracing was enabled.

fa0ad6575f kconfig: adapt update-po-config to new UML layout
Commit 5c48b108 ("um: take arch/um/sys-x86 to arch/x86/um") broke the
make target update-po-config, as its symlink trick (again) fails.
(Previous breakage was fixed with commit bdc69ca4 ("kconfig: change
update-po-config to reflect new layout of arch/um").)

The new UML layout allows to drop the symlick trick entirely. And if,
one day, another architecture supports UML too, that should now work
without again breaking this make target.

523817bd22 ARM: amba: Auto-generate AMBA driver module aliases during modpost
This patch adds the necessary support in file2alias.c to define
suitable aliases based on the amba_id table in AMBA driver modules.

This should be sufficient to allow such modules to be auto-loaded
via udev.  The AMBA bus driver's uevent hotplug code is also
modified to pass an approriate MODALIAS string in the event.

For simplicity, the AMBA ID is treated an an opaque 32-bit numeber.
Module alises use patterns as appropriate to describe the value-
mask pairs described in the driver's amba_id list.

The proposed alias format is (extended regex):

    ^amba:d(HEX){8}$

Where HEX is a single upper-case HEX digit or a pattern (? or []
expression) matching a single upper-case HEX digit, as expected by
udev.

"d" is short for "device", following existing alias naming
conventions for other device types.  This adds some flexibility for
unambiguously extending the alias format in the future by adding
additional leading and trailing fields, if this turns out to be
necessary.

account; the sole user of objhdr-y, linux/version.h, should be
migrated over at some later date.
