Some cleanup of PAI

Update PULL_TIMERS_VECTOR number

2011-08-27T14:14:19+00:00

From 2.6.39 the "0xee" vector number that we used for pull_timers
low-level management is is use by invalidate_tlb_X interrupts.
Move the pull_timers vector below the max size of invalidate_tlb.

Fix prototype mismatching and synch syscall numbers

2011-08-27T14:10:06+00:00

* Update prototypes for switched_to(), prio_changed(), select_task_rq().
* Fix missing pid field in printk output.
* Synchronize syscall numbers for arm and x86.

Merge 'Linux v3.0' into Litmus

2011-08-27T14:06:11+00:00

Some notes:
* Litmus^RT scheduling class is the topmost scheduling class
  (above stop_sched_class).
* scheduler_ipi() function (e.g., in smp_reschedule_interrupt())
  may increase IPI latencies.
* Added path into schedule() to quickly re-evaluate scheduling
  decision without becoming preemptive again. This used to be
  a standard path before the removal of BKL.

x86: Make Dell Latitude E6420 use reboot=pci

2011-07-21T18:47:17+00:00

Yet another variant of the Dell Latitude series which requires
reboot=pci.

From the E5420 bug report by Daniel J Blueman:

> The E6420 is affected also (same platform, different casing and
> features), which provides an external confirmation of the issue; I can
> submit a patch for that later or include it if you prefer:

x86: Make Dell Latitude E5420 use reboot=pci

2011-07-21T18:45:49+00:00

Rebooting on the Dell E5420 often hangs with the keyboard or ACPI
methods, but is reliable via the PCI method.

[ hpa: this was deferred because we believed for a long time that the
  recent reshuffling of the boot priorities in commit
  660e34cebf0a11d54f2d5dd8838607452355f321 fixed this platform.
  Unfortunately that turned out to be incorrect. ]

* 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip:
  x86. reboot: Make Dell Latitude E6320 use reboot=pci
  x86, doc only: Correct real-mode kernel header offset for init_size
  x86: Disable AMD_NUMA for 32bit for now

x86. reboot: Make Dell Latitude E6320 use reboot=pci

2011-07-13T04:42:48+00:00

The Dell Latitude E6320 doesn't reboot unless reboot=pci is set.
Force it thanks to DMI.

mm: Move definition of MIN_MEMORY_BLOCK_SIZE to a header

2011-07-12T01:08:01+00:00

The macro MIN_MEMORY_BLOCK_SIZE is currently defined twice in two .c
files, and I need it in a third one to fix a powerpc bug, so let's
first move it into a header
