- 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"

kbuild: rename cmd_{bzip2,lzma,lzo,lz4,xzkern,zstd22}

GZIP-compressed files end with 4 byte data that represents the size
of the original input. The decompressors (the self-extracting kernel)
exploit it to know the vmlinux size beforehand. To mimic the GZIP's
trailer, Kbuild provides cmd_{bzip2,lzma,lzo,lz4,xzkern,zstd22}.
Unfortunately these macros are used everywhere despite the appended
size data is only useful for the decompressors.

There is no guarantee that such hand-crafted trailers are safely ignored.
In fact, the kernel refuses compressed initramdfs with the garbage data.
That is why usr/Makefile overrides size_append to make it no-op.

To limit the use of such broken compressed files, this commit renames
the existing macros as follows:

cmd_bzip2 --> cmd_bzip2_with_size
cmd_lzma --> cmd_lzma_with_size
cmd_lzo --> cmd_lzo_with_size
cmd_lz4 --> cmd_lz4_with_size
cmd_xzkern --> cmd_xzkern_with_size
cmd_zstd22 --> cmd_zstd22_with_size

To keep the decompressors working, I updated the following Makefiles
accordingly:

arch/arm/boot/compressed/Makefile
arch/h8300/boot/compressed/Makefile
arch/mips/boot/compressed/Makefile
arch/parisc/boot/compressed/Makefile
arch/s390/boot/compressed/Makefile
arch/sh/boot/compressed/Makefile
arch/x86/boot/compressed/Makefile

I reused the current macro names for the normal usecases; they produce
the compressed data in the proper format.

I did not touch the following:

arch/arc/boot/Makefile
arch/arm64/boot/Makefile
arch/csky/boot/Makefile
arch/mips/boot/Makefile
arch/riscv/boot/Makefile
arch/sh/boot/Makefile
kernel/Makefile

This means those Makefiles will stop appending the size data.

I dropped the 'override size_append' hack from usr/Makefile.

ARM: decompressor: disable stack protector

Enabling the stack protector in the decompressor is of dubious value,
given that it uses a fixed value for the canary, cannot print any output
unless CONFIG_DEBUG_LL is enabled (which relies on board specific build
time settings), and is already disabled for a good chunk of the code
(libfdt).

So let's just disable it in the decompressor. This will make it easier
in the future to manage the command line options that would need to be
removed again in this context for the TLS register based stack
protector.
