"Updates for IRQ stacks and virtually mapped stack support, and ftrace:

- Support for IRQ and vmap'ed stacks

This 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 four 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]

- fixes and updates in [3]

- ftrace fixes and cleanups

Make all flavors of ftrace available on all builds, regardless of
ISA choice, unwinder choice or compiler [4]:

- use ADD not POP where possible

- fix a couple of Thumb2 related issues

- enable HAVE_FUNCTION_GRAPH_FP_TEST for robustness

- enable the graph tracer with the EABI unwinder

- avoid clobbering frame pointer registers to make Clang happy

- Fixes for the above"

ARM: module: implement support for PC-relative group relocations

Add support for the R_ARM_ALU_PC_Gn_NC and R_ARM_LDR_PC_G2 group
relocations [0] so we can use them in modules. These will be used to
load the current task pointer from a global variable without having to
rely on a literal pool entry to carry the address of this variable,
which may have a significant negative impact on cache utilization for
variables that are used often and in many different places, as each
occurrence will result in a literal pool entry and therefore a line in
the D-cache.

The only exception is a bit of cleanups on itanic (getting rid of
redundant stack unwinds - each access_uarea() call does it and we call
that 7 times in a row in ptrace_[sg]etregs(), *after* having done it
ourselves in the caller; location where the user registers have been
spilled won't change under us, and we can bloody well just call
access_elf_reg() directly, giving it the unw_frame_info we'd
calculated for our own purposes)"

Implement the necessary changes in the ARM assembler boot code to permit
the relative alignment of the physical and the virtual addresses of the
kernel to be as little as 2 MiB, as opposed to the minimum of 16 MiB we
support today.

ARM: module: add support for place relative relocations

When using the new adr_l/ldr_l/str_l macros to refer to external symbols
from modules, the linker may emit place relative ELF relocations that
need to be fixed up by the module loader. So add support for these.
