The MIPS processor is limited to 64 external interrupt sources. Using a
greater number without IRQ sharing requires reading platform-specific
registers. On such platforms, reading the IntCtl register to determine
which interrupt corresponds to a timer interrupt will not work.
On MIPSR2 systems there is a solution - the TI bit in the Cause register,
specifically indicates that a timer interrupt has occured. This patch uses
that bit to detect interrupts for MIPSR2 processors, which may be expected
to work regardless of how the timer interrupt may be routed in the hardware.

POSIX requires $((<expression>)) arithmetic in sh only to have long
arithmetic so on 32-bit sh binaries might do only 32-bit arithmetic but
the arithmetic done in arch/mips/boot/compressed/Makefile needs 64-bit.
I play with the AR7 platform, so VMLINUX_LOAD_ADDRESS is
0xffffffff94100000, and for an example 4MiB kernel
VMLINUZ_LOAD_ADDRESS is made out to be:
----
alex@berk:~$ bash -c 'printf "%x\n" $((0xffffffff94100000 + 0x400000))'
ffffffff94500000
alex@berk:~$ dash -c 'printf "%x\n" $((0xffffffff94100000 + 0x400000))'
80000000003fffff
----
The former is obviously correct whilst the later breaks things royally.
Fortunately working with only the lower 32bit's works for both bash and
dash:
----
$ bash -c 'printf "%x\n" $((0x94100000 + 0x400000))'
94500000
$ dash -c 'printf "%x\n" $((0x94100000 + 0x400000))'
94500000
----
So, we can split the original 64bit string to two parts, and only
calculate the low 32bit part, which is big enough (1GiB kernel sizes
anyone?) for a normal Linux kernel image file, now, we calculate the
VMLINUZ_LOAD_ADDRESS like this:
1. if present, append top 32bit of VMLINUX_LOAD_ADDRESS" as a prefix
2. get the sum of the low 32bit of VMLINUX_LOAD_ADDRESS + VMLINUX_SIZE
This patch fixes vmlinuz kernel builds on systems where only a
32bit-only math shell is available.
Patch Changelog:
Version 2
- simplified method by using 'expr' for 'substr' and making it work
with dash once again
Version 1
- Revert the removals of '-n "$(VMLINUX_SIZE)"' to avoid the error
of "make clean"
- Consider more cases of the VMLINUX_LOAD_ADDRESS
Version 0

When we queue an interrupt to the local apic, we set the IRR before the TMR.
The vcpu can pick up the IRR and inject the interrupt before setting the TMR,
and perhaps even EOI it, causing incorrect behaviour.
The race is really insignificant since it can only occur on the first
interrupt (usually following interrupts will not change TMR), but it's better
closed than open.
Fixed by reordering setting the TMR vs IRR.

Commit d1c84f79a6
leads to a regression when microcode_amd.c is compiled into the kernel.
It causes a big boot delay because the firmware is not available.
See http://marc.info/?l=linux-kernel&m=126267290920060
It also renders the reload sysfs attribute useless.
Fixing this is too intrusive for an -rc5 kernel.
Thus I'd like to restore the microcode loading behaviour of kernel
2.6.32.

nodes_possible_map does not currently include nodes that have SRAT
entries that are all ACPI_SRAT_MEM_HOT_PLUGGABLE since the bit is
cleared in nodes_parsed if it does not have an online address range.
Unequivocally setting the bit in nodes_parsed is insufficient since
existing code, such as acpi_get_nodes(), assumes all nodes in the map
have online address ranges. In fact, all code using nodes_parsed
assumes such nodes represent an address range of online memory.
nodes_possible_map is created by unioning nodes_parsed and
cpu_nodes_parsed; the former represents nodes with online memory and
the latter represents memoryless nodes. We now set the bit for
hotpluggable nodes in cpu_nodes_parsed so that it also gets set in
nodes_possible_map.
[ hpa: Haicheng Li points out that this makes the naming of the
variable cpu_nodes_parsed somewhat counterintuitive. However, leave
it as is in the interest of keeping the pure bug fix patch small. ]

During suspend, the kernel timekeeping subsystem is shut down. Before
suspend and upon resume, it uses a weak function
read_persistent_clock() to determine the amount of time that elapsed
during suspend.
This function was not implemented on OMAP, so from the timekeeping
subsystem perspective (and thus userspace as well) it appeared that no
time elapsed during suspend.
This patch uses the 32k sync timer as a the persistent clock.
NOTE: This does *NOT* fully handle wrapping of the 32k sync timer, so
more than one wrapping of the 32k sync timer during suspend may
cause problems. Also note there are not interrupts when the 32k
sync timer wraps, so something else has to be done.

In the current implementation the sysconfig value is read into
_sysc_cache once and an actual update to the sysconfig register
happens only if the new value paased is differnt from the one in _sysc_cache.
_sysc_cache is updated only if _HWMOD_SYSCONFIG_LOADED is not set.
This can lead to the follwing issue if off mode is enabled in modules
which employs "always-retore" mechanism of context save and restore.
a. The module sets the sysconfig register through omap_device_enable.
Here _sysc_cache is updated with the value written to the sysconfig
register and left.
b. The power domain containig the module enters off mode and the
module context is lost.
c. The module in use becomes active and calls omap_device_enable to
enable itself. Here a read of sysconfig register does not happen
as _HWMOD_SYSCONFIG_LOADED flag is set. The value to be written
to the sysconfig register will be same as the one written in step a.
Since _sysc_cache reflects the previous written value an update
of the sysconfig register does not happen.
This means in modules which employs "always-restore" mechanism
after off , the sysconfig regsiters will never get updated.
This patch introduces a flag SYSC_NO_CACHE which if set ensures that the
sysconfig register is always read into _sysc_cache before an update is
attempted.
This flags need to be set only by modules which does not do a context save
but re-initializes the registers every time the module is accessed. This
includes modules like i2c, smartreflex etc.

The m68knommu coldfire pit clocksource looks like it was incorrectly
marked as a continuous clocksource. Running with it marked as a
continuous clocksource could cause hangs when the system switches to
highres mode or enables nohz.
This patch removes the CLOCK_SOURCE_IS_CONTINUOUS flag on the coldfire pit
clocksource. This will disallow systems using this clocksource from
entering oneshot mode (disabling highres timers and nohz).

This patch converts sparc (specifically sparc32) to use GENERIC_TIME via
the arch_getoffset() infrastructure, reducing the amount of arch
specific code we need to maintain.
The sparc architecture is one of the last 3 arches that need to be
converted.
This patch applies on top of Linus' current -git tree
I've taken my best swing at converting this, but I'm not 100% confident
I got it right. My cross-compiler is now out of date (gcc4.2) so I
wasn't able to check if it compiled. Any assistance from arch
maintainers or testers to get this merged would be great.

Remove the definitions we've deleted in the previous updates to the
clksrc_clk for arch/arm/plat-s5pc1xx/include/plat/regs-clock.h.
Added comments about the removal to the clock header since we only need
these defines in one place (and they've now been removed there) we get
rid of them from the header.

Remove the individual 'struct clksrc_clks' and place them into an array
so that we can simply use s3c_register_clksrcs to register tham all in one
go.
Since the spdif clock relies on the audio clock, move the audio clocks
into their own arrary.

what where missed from the clock list.

Remove the copy of the old s3c64xx struct clksrc_clk and use the new one

Add a common entry-macro-vic2.S for systems where there are two VICs
so that the machine or platform directories just need to setup the
correct information before including <asm/entry-macro-vic2.S> into
their own entry-macro.S file.
Since this code is from the S3C64XX project, we update the S3C64XX
machine entry code to use this new header.

Move the VIC based timer interrupt handling out of plat-s3c64xx and
into plat-samsung to be re-used for other systems. This also reduces
the code size as we now have a common init routine and use the irq_desc
to store the interrupt number of the timer.

The new code calls the clock setup code on registration which
can be before the clock system has been fully initialised. The
following code re-does this setup at the end of the clock
registration and thus we get two printings.

the necessary resume work.
