1c0350bd0c [PATCH] Xtensa: Add ktermios and minor filename fix
The kernel termios (ktermios) changes were somehow missed for Xtensa.  This
patch adds the ktermios structure and also includes some minor file name
fix that was missed in the syscall patch.

8c1bc04e79 [PATCH] fix more workqueue build breakage (tps65010)
More fixes to build breakage from the work_struct changes ...  this updates
the tps65010 driver.  Plus, fix some dependencies related to the way it's
used on the OMAP OSK: force static linking there, since the resulting
kernel can't link.

NOTE that until the i2c core gets fixed to work without SMBUS_QUICK,
kernels needing this driver must still use "tps65010.force=0,0x48" on the
command line.

8b9c6671f8 [CPUFREQ] speedstep-centrino should ignore upper performance control bits
On some systems there could be bits set in the upper half of
the control value provided by the _PSS object.  These bits are
only relevant for cpufreq drivers that use IO ports which are not
currently supported by the speedstep-centrino driver.  The current
MSR oriented code assumes that upper bits are not set and thus
fails to work correctly when they are.  e.g. the control and status
value equality check failed on the IBM x3650 even though the ACPI
spec allows inequality.

08ed38b680 [IA64] enable trap code on slot 1
Because slot 1 of one instr bundle crosses border of two consecutive
8-bytes, kprobe on slot 1 is disabled. This patch enables kprobe on
slot1, it only replaces higher 8-bytes of the instruction bundle and
changes the exception code to ignore the low 12 bits of the break
number (which is across the border in the lower 8-bytes of the bundle).

For those instructions which must execute regardless qp bits,
kprobe on slot 1 is still disabled.

a460ef8d0a [IA64] fix possible XPC deadlock when disconnecting
This patch eliminates a potential deadlock that is possible when XPC
disconnects a channel to a partition that has gone down. This deadlock will
occur if at least one of the kthreads created by XPC for the purpose of making
callouts to the channel's registerer is detained in the registerer and will
not be returning back to XPC until some registerer request occurs on the now
downed partition. The potential for a deadlock is removed by ensuring that
there always is a kthread available to make the channel disconnecting callout
to the registerer.

1cf24bdbbb [IA64] - Reduce overhead of FP exception logging messages
Improve the scalability of the fpswa code that rate-limits
logging of messages.

There are 2 distinctly different problems in this code.

1) If prctl is used to disable logging, last_time is never
   updated. The result is that fpu_swa_count is zeroed out on
   EVERY fp fault. This causes a very very hot cache line.
   The fix reduces the wallclock time of a 1024p FP exception test
   from 28734 sec to 19 sec!!!

2) On VERY large systems, excessive messages are logged because
   multiple cpus can each reset or increment fpu_swa_count at
   about the same time. The result is that hundreds of messages
   are logged each second. The fixes reduces the logging rate
   to ~1 per second.

ad1c3ba7e5 [IA64] Kexec/Kdump: honour non-zero crashkernel offset.
There seems to be a value in both allowing the kernel to determine
the base offset of the crashkernel automatically and allowing
users's to sepcify it.

The old behaviour on ia64, which is still the current behaviour on
most architectures is for the user to always specify the address.
Recently ia64 was changed so that it is always automatically determined.

With this patch the kernel automatically determines the offset if
the supplied value is 0, otherwise it uses the value provided.

This should probably be backed by a documentation change.

45a98fc622 [IA64] CONFIG_KEXEC/CONFIG_CRASH_DUMP permutations
Actually, on reflection I think that there is a good case for
keeping the options separate. I am thinking particularly of people
who want a very small crashdump kernel and thus don't want to compile
in kexec.

The patch below should fix things up so that all valid combinations of
KEXEC, CRASH_DUMP and VMCORE compile cleanly - VMCORE depends on
CRASH_DUMP which is why I said valid combinations. In a nutshell
it just untangles unrelated code and switches around a few defines.

Please note that it creats a new file, arch/ia64/kernel/crash_dump.c
This is in keeping with the i386 implementation.

adf142e379 [IA64] Do not call SN_SAL_SET_CPU_NUMBER twice on cpu 0
This is an SN specific patch.

Architectually, cpu_init is always called twice on cpu 0
and thus resulted in two SN_SAL_SET_CPU_NUMBER calls.

This was harmless in production kernel; however, it can
cause problem on booting up a crashdump kernel at Altix.

Here is the patch that detects the second sn_cpu_init
call and skips the second call to SN_SAL_SET_CPU_NUMBER.

2efac77e82 [MIPS] Discard .exit.text and .exit.data at runtime.
While the recent cset 86384d5441 did improve
things it didn't resolve all the problems.  So bite the bullet and discard
.exit.text and .exit.data at runtime.  Which of course sucks because it
bloats binaries with code that will never ever be used but it's the only
thing that will work reliable as demonstrated by the function sd_major() in
drivers/scsi/sd.c.

Gcc may compile sd_major() using a jump table which it will put into
.rodata.  If it also inlines sd_major's function body into exit_sd() which
gcc > 3.4.x does.  If CONFIG_BLK_DEV_SD has been set to y we would like ld
to discard exit_sd's code at link time.  However sd_major happens to
contain a switch statement which gcc will compile using a jump table in
.rodata on the architectures I checked.  So, when ld later discards
.exit.text only the jump table in .rodata with its stale references to
the discard .exit.text will be left which any no antique ld will honor
with a link error.

79890c5124 sh: Fixup kernel_execve() for syscall cleanups.
SH-2 and SH-2A need to use a different syscall base for the trapa
vector than the other parts, so fixup the logic in the kernel_execve()
case.

b652c23cb0 sh: Fix get_wchan().
Some time ago the schedule frame size changed and we failed to reflect
this in get_wchan() at the time. This first popped up as a problem on
SH7751R where schedule_frame ended up being unaligned and generating
an unaligned trap. This fixes it up again..

dc34d312c7 sh: BUG() handling through trapa vector.
Previously we haven't been doing anything with verbose BUG() reporting,
and we've been relying on the oops path for handling BUG()'s, which is
rather sub-optimal.

This switches BUG handling to use a fixed trapa vector (#0x3e) where we
construct a small bug frame post trapa instruction to get the context
right. This also makes it trivial to wire up a DIE_BUG for the atomic
die chain, which we couldn't really do before.

This can use the generic routines, so kill off the board-specific ones.
