ARM: support for IRQ and vmap'ed stacks
This PR covers all the work related to implementing IRQ stacks and
vmap'ed stacks for all 32-bit ARM systems that are currently supported
by the Linux kernel, including RiscPC and Footbridge. It has been
submitted for review in three different waves:
- IRQ stacks support for v7 SMP systems [0],
- vmap'ed stacks support for v7 SMP systems[1],
- extending support for both IRQ stacks and vmap'ed stacks for all
remaining configurations, including v6/v7 SMP multiplatform kernels
and uniprocessor configurations including v7-M [2]

Ard Biesheuvel (27):
ARM: decompressor: disable stack protector
ARM: stackprotector: prefer compiler for TLS based per-task protector
ARM: remove some dead code
ARM: assembler: introduce bl_r macro
ARM: unwind: support unwinding across multiple stacks
ARM: export dump_mem() to other objects
ARM: unwind: dump exception stack from calling frame
ARM: backtrace-clang: avoid crash on bogus frame pointer
ARM: implement IRQ stacks
ARM: call_with_stack: add unwind support
ARM: run softirqs on the per-CPU IRQ stack
ARM: memcpy: use frame pointer as unwind anchor
ARM: memmove: use frame pointer as unwind anchor
ARM: memset: clean up unwind annotations
