kexec fixes for OMAP
 
The following changes since commit ddb83416f852e38c46b46d523e717c086024fc0f:

UBUNTU: Ubuntu-3.2.0-8.15 (2012-01-11 11:29:57 +0100)

are available in the git repository at:
git://kernel.ubuntu.com/ppisati/ubuntu-precise.git master-kexecfix


This patchset is part of 3.3rc1 and fixes kexec on ARM: i restricted the
support to OMAP-only and even if the pull is pretty big, it is isolated
in arch/arm/*, so x86 will be safe to any fallout.

For more information about the original code:

All the patches are a straight cherry-pick, except for:

[PATCH 03/20] ARM: restart: allow platforms more flexibility specifying
restart mode

and

[PATCH 06/20] ARM: 7159/1: OMAP: Introduce local common.h files

where 2 trivial conflicts came up.

I'm proposing it for master, thus all the topic branches will get it via rebase.

Tested on BeagleXM.

Russell King (6):
ARM: restart: add restart hook to machine_desc record
ARM: restart: allow platforms more flexibility specifying restart mode
ARM: restart: move reboot failure handing into machine_restart()
ARM: restart: remove argument to setup_mm_for_reboot()
ARM: restart: only perform setup for restart when soft-restarting
ARM: restart: omap: use new restart hook

Santosh Shilimkar (1):
ARM: 7189/1: OMAP3: Fix build break in cpuidle34xx.c because of irq function

Tony Lindgren (2):
ARM: 7159/1: OMAP: Introduce local common.h files
ARM: 7194/1: OMAP: Fix build after a merge between v3.2-rc4 and ARM restart changes

Will Deacon (10):
ARM: idmap: populate identity map pgd at init time using .init.text
ARM: suspend: use idmap_pgd instead of suspend_pgd
ARM: proc-*.S: place cpu_reset functions into .idmap.text section
ARM: idmap: use idmap_pgd when setting up mm for reboot
ARM: head.S: only include __turn_mmu_on in the initial identity mapping
ARM: SMP: use idmap_pgd for mapping MMU enable during secondary booting
ARM: lib: add call_with_stack function for safely changing stack
ARM: reset: implement soft_restart for jumping to a physical address
ARM: stop: execute platform callback from cpu_stop code
ARM: kexec: use soft_restart for branching to the reboot buffer
