These cleanups are basically all over the place. The idea is to collect
changes with minimal impact but large number of changes so we can avoid
them from distracting in the diffstat in the other series.
A significant number of lines get removed here, in particular because
the ixp2000 and ixp23xx platforms get removed. These have never been
extremely popular and have fallen into disuse over time with no active
maintainer taking care of them. The u5500 soc never made it into a
product, so we are removing it from the ux500 platform.
Many good cleanups also went into the at91 and omap platforms, as has
been the case for a number of releases.

This patch removes support for ARMv3 CPUs, which haven't worked properly
for quite some time (see the FIXME comment in arch/arm/mm/fault.c). The
only V3 parts left is the cache model for ARMv3, which is needed for some
odd reason by ARM740T CPUs, and being able to build with -march=armv3,
which is required for the RiscPC platform due to its bus structure.

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.

The arch/arm/mach-exynos4 directory (CONFIG_ARCH_EXYNOS4) has
made for plaforms based on EXYNOS4 SoCs. But since upcoming
Samsung's SoCs such as EXYNOS5 (ARM Cortex A15) can reuse most
codes in current mach-exynos4, one mach-exynos directory will
be used for them.
This patch changes to CONFIG_ARCH_EXYNOS (arch/arm/mach-exynos)
but keeps original CONFIG_ARCH_EXYNOS4 in mach-exynos/Kconfig to
avoid changing in driver side.

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
revive this code, it could be retrieved from the Git repository, and
ideally be merged in mach-w90x900/ instead.

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.

SiRFprimaII is the latest generation application processor from CSR’s
Multifunction SoC product family. Designed around an ARM cortex A9 core,
high-speed memory bus, advanced 3D accelerator and full-HD multi-format
video decoder, SiRFprimaII is able to meet the needs of complicated
applications for modern multifunction devices that require heavy concurrent
applications and fluid user experience. Integrated with GPS baseband,
analog and PMU, this new platform is designed to provide a cost effective
solution for Automotive and Consumer markets.
This patch adds the basic support for this SoC and EVB board based on device

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
mach-stmp378x can go.

- It can be doubted that this worked at all. Check the DMA routines in

actually writing into registers for APBH.
- There is only one board defined (which I couldn't find any trace of
despite being a development board). In this board, only two devices
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
mach-mxs.

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

Commit 18991197b4 added --build-id
linker option when toolchain supports it. ARM one does, but for some
reason places the section at 0 when linker script doesn't mention it
explicitly.
The 1e621a8e37 worked around the problem
removing this section from binary image with explicit objcopy options,
but it still exists in vmlinux, confusing tools like debuggers and perf.
This problem was discussed here:
http://lists.infradead.org/pipermail/linux-arm-kernel/2010-May/015994.htmlhttp://lists.infradead.org/pipermail/linux-arm-kernel/2010-May/015994.html
but the proposed changes to the linker script were substantial.
This patch simply places NOTES (36 bytes long, at least when compiled
with CodeSourcery toolchain) between data and bss, which seem to be
the right place (and suggested by the sample linker script in
include/asm-generic/vmlinux.lds.h).
It is enough to place it correctly in vmlinux (so debuggers are happy):
