Based of Matt Evans's PPC64 implementation.

The compiler generates ARM instructions but interworking is
supported for Thumb2 kernels.

Supports both little and big endian. Unaligned loads are emitted
for ARMv6+. Not all the BPF opcodes that deal with ancillary data
are supported. The scratch memory of the filter lives on the stack.
Hardware integer division is used if it is available.

Enabled in the same way as for x86-64 and PPC64:

	echo 1 > /proc/sys/net/core/bpf_jit_enable

A value greater than 1 enables opcode output.

This architecture received only generic maintenance since December 2009
when it was originally submitted, and no actual additional support since
then.  It has no defconfig entry either, meaning that it was never built
by the ARM KAutobuild.  Incidentally it currently doesn't build either
when CONFIG_MACH_NUC932EVB is selected which is the only possible config
choice.

This is therefore dead code and should be removed.  If someone wants to

For this we need CONFIG_AUTO_ZRELADDR and CONFIG_ARM_PATCH_PHYS_VIRT.
Signed-off-by: NSascha Hauer <s.hauer@pengutronix.de>

MSMs post 8x50 have 2Mb at the beginning of RAM reserved for
shared memory. Since the kernel hasn't typically been told this
RAM exists, PHYS_OFFSET has been set to 0xN0200000 and the memory
atags passed to the kernel have matched. This doesn't play nicely
with things such as AUTO_ZRELADDR, which doesn't work at all, and
dynamic phys to virt, which requires an MSM specific workaround.

Work around these issues by telling the kernel RAM starts at
0xN0000000 (it actually does) and fixup the atags from the
bootloader (if necessary) to say the same. In addition, make sure
to set TEXT_OFFSET at least 2Mb beyond the start of RAM so that
the kernel doesn't end up being decompressed into shared memory.

After doing this, AUTO_ZRELADDR should work on MSM with no
problems and ARM_PATCH_PHYS_VIRT_16BIT should no longer be
necessary.

This mach has not seen any updates since the initial inclusion besides
generic cleanup. Furthermore:

- The i.MX23 covered in mach-mxs is just a renamed version of the
  STMP378x.

- mach-stmp378x has a lot of reinvented interfaces, leaking all sorts of
  mach-related includes into the drivers. One example is the dmaengine
  which does not use the linux dmaengine-API but some privately exported
  symbols. So drivers cannot be reused. mach-mxs does it better.

- There is only one board defined (which I couldn't find any trace of
  despite being a development board). It has been converted to
  mach-mxs in a previous patch.

Since the only user of this mach was converted, it means that

- There is only one board defined (which I couldn't find any trace of

  have resources, the debug uart and the application uart. Neither of
  those have the needed custom drivers merged (and never will). debug
  uart is amba-pl011 which has an in-kernel driver without the
  mach-specific-stuff. appuart has a driver which was introduced for
  mach-mxs, and this one is reusable for a properly done mach.

So, this single board registers only unsupported devices and the
generic code looks suspicious and has poor design. Delete this
stuff. If there is interest, it is wiser to restart using

Various binutils versions can resolve Thumb-2 branches to
locally-defined, preemptible global symbols as short-range "b.n"
branch instructions.

This is a problem, because there's no guarantee the final
destination of the symbol, or any candidate locations for a
trampoline, are within range of the branch.  For this reason, the
kernel does not support fixing up the R_ARM_THM_JUMP11 (102)
relocation in modules at all, and it makes little sense to add
support.

The symptom is that the kernel fails with an "unsupported
relocation" error when loading some modules.

Until fixed tools are available, passing
-fno-optimize-sibling-calls to gcc should prevent gcc generating
code which hits this problem, at the cost of a bit of extra runtime
stack usage in some cases.

The problem is described in more detail at:
    https://bugs.launchpad.net/binutils-linaro/+bug/725126

Only Thumb-2 kernels are affected.

This patch adds a new CONFIG_THUMB2_AVOID_R_ARM_THM_JUMP11 config
option which adds -fno-optimize-sibling-calls to CFLAGS_MODULE

Commit 18991197 added --build-id

The 1e621a8e worked around the problem
removing this section from binary image with explicit objcopy options,
