[PATCH v2 0/9] ARM: Thumb-2: Various fixes for building Thumb-2 kernels

[Dave Martin]

This series fixes various minor problems affecting building with
CONFIG_THUMB2_KERNEL.

v2: 

  * Improve zImage header layout patch based on feedback.
  * Disable kprobes via Kconfig when using CONFIG_THUMB2_KERNEL (for now)
  * Force longer-range Thumb-2 branch encoding for some branches in head.S,
	to avoid fixup errors when vmlinux is large.

Applies to 2.6.37-rc3


v1:

Fix misaligned data risks resulting from .long/.word without .align:
 * ARM: kexec: Correct data alignment for CONFIG_THUMB2_KERNEL
 * ARM: vfp: Correct data alignment for CONFIG_THUMB2_KERNEL
 * ARM: Thumb-2: Correct data alignment for CONFIG_THUMB2_KERNEL in bootp/init.S
 * ARM: Thumb-2: Correct data alignment for CONFIG_THUMB2_KERNEL in kernel/head.S
 * ARM: Thumb-2: Correct data alignment for CONFIG_THUMB2_KERNEL in mm/proc-v7.S

Fix Thumb-2 incompatibilities in compressed kernel entry code,
to avoid build failures:
 * ARM: Thumb-2: Fix CONFIG_THUMB2_KERNEL breakage in compressed/head.S

Fix strange zImage header layout when building Thumb-2 kernels:
 * ARM: Thumb-2: Restore sensible zImage header layout for CONFIG_THUMB2_KERNEL
