[PATCH v2 0/6] Consolidate identity mapping code in idmap.c

[Will Deacon]

Hello,

This is version 2 of the patch series originally posted here:

 http://lists.infradead.org/pipermail/linux-arm-kernel/2011-November/073033.html

Changes from v1 include:
	* Updated following Catalin's comments
	* Rebased onto rmk/devel-stable
	* Includes update to SMP booting so that the idmap_pgd can be
	  used there too

This is a pre-requisite for my kexec patches, which I will post separately.

All feedback welcome.

Thanks,

Will

  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
