ARM: Delete ARM11MPCore (ARM11 ARMv6K SMP) support

This ARM11 SMP configuration was one of the first SMP configurations
the ARM kernel supported, but it has the downside of odd DMA handling,
odd cache tagging, and often (as of recent) completely broken cache
handling on the ARM RealView PB11MPCore test chips. To boot the
platform it was necessary to completely disable the cache.
When it comes to the EB 11MPCore it is unclear if this ever worked.

These reference designs are now the only ARMv6K SMP platforms.

As only reference designs of purely academic interest remain, and
since the special-cased DMA and PMU code is hard to maintain and
doesn't really work, it is not really worth our time.

Delete the ARM11MPCore support along with:

- The special DMA quirk CONFIG_DMA_CACHE_RWFO that is only used
on ARMv6K SMP, and we are the last ARMV6K system leaving the
building and the cache handling is awkward, so good-bye.

- The special PMU handling that was only used by ARM11MPCore.

The following is left behind:

- TIMER_OF_DECLARE(arm_twd_11mp, "arm,arm11mp-twd-timer", ...)
in arch/arm/kernel/smp_twd.c, this is still in use by Marvell MMP3
arch/arm/boot/dts/marvell/mmp3.dtsi

- IRQCHIP_DECLARE(arm11mp_gic, "arm,arm11mp-gic", ...)
in drivers/irqchip/irq-gic.c, this is still in use by Marvell MMP3
arch/arm/boot/dts/marvell/mmp3.dtsi

- A compatible for the arm11mpcore SCU, since this was mistakedly
used for the Cortex-A9 version of RealView EB.

These are unfortunate but will need to be kept around for
compatibility. New Marvell-specific compatibles should however probably
be added.

ARM: rework endianess selection

Choosing big-endian vs little-endian kernels in Kconfig has not worked
correctly since the introduction of CONFIG_ARCH_MULTIPLATFORM a long
time ago.

The problems is that CONFIG_BIG_ENDIAN depends on
ARCH_SUPPORTS_BIG_ENDIAN, which can set by any one platform
in the config, but would actually have to be supported by all
of them.

This was mostly ok for ARMv6/ARMv7 builds, since these are BE8 and
tend to just work aside from problems in nonportable device drivers.
For ARMv4/v5 machines, CONFIG_BIG_ENDIAN and CONFIG_ARCH_MULTIPLATFORM
were never set together, so this was disabled on all those machines
except for IXP4xx.

As IXP4xx can now become part of ARCH_MULTIPLATFORM, it seems better to
formalize this logic: all ARMv4/v5 platforms get an explicit dependency
on being either big-endian (ixp4xx) or little-endian (the rest). We may
want to fix ixp4xx in the future to support both, but it does not work
in LE mode at the moment.

For the ARMv6/v7 platforms, there are two ways this could be handled

a) allow both modes only for platforms selecting
'ARCH_SUPPORTS_BIG_ENDIAN' today, but only LE mode for the
others, given that these were added intentionally at some
point.

b) allow both modes everwhere, given that it was already possible
to build that way by e.g. selecting ARCH_VIRT, and that the
list is not an accurate reflection of which platforms may or
may not work.

Out of these, I picked b) because it seemed slighly more logical
to me.

- extending support for both IRQ stacks and vmap'ed stacks for all

- 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

ARM: percpu: add SMP_ON_UP support

Permit the use of the TPIDRPRW system register for carrying the per-CPU
offset in generic SMP configurations that also target non-SMP capable
ARMv6 cores. This uses the SMP_ON_UP code patching framework to turn all
TPIDRPRW accesses into reads/writes of entry #0 in the __per_cpu_offset
array.

While at it, switch over some existing direct TPIDRPRW accesses in asm
code to invocations of a new helper that is patched in the same way when
necessary.

Note that CPU_V6+SMP without SMP_ON_UP results in a kernel that does not
boot on v6 CPUs without SMP extensions, so add this dependency to
Kconfig as well.

ARM: 9137/1: disallow CONFIG_THUMB with ARMv4

We can currently build a multi-cpu enabled kernel that allows both ARMv4
and ARMv5 CPUs, and also supports THUMB mode in user space.

However, returning to user space in this configuration with the usr_ret
macro requires the use of the 'bx' instruction, which is refused by
the assembler:

arch/arm/kernel/entry-armv.S: Assembler messages:
arch/arm/kernel/entry-armv.S:937: Error: selected processor does not support `bx lr' in ARM mode
arch/arm/kernel/entry-armv.S:960: Error: selected processor does not support `bx lr' in ARM mode
arch/arm/kernel/entry-armv.S:1003: Error: selected processor does not support `bx lr' in ARM mode
<instantiation>:2:2: note: instruction requires: armv4t
bx lr

While it would be possible to handle this correctly in principle, doing so
seems to not be worth it, if we can simply avoid the problem by enforcing
that a kernel supporting both ARMv4 and a later CPU architecture cannot
run THUMB binaries.

This turned up while build-testing with clang; for some reason,
gcc never triggered the problem.

When configuring the kernel for big-endian, we set either BE-8 or BE-32
based on the CPU architecture level. Until linux-4.4, we did not have
any ARMv7-M platform allowing big-endian builds, but now i.MX/Vybrid
is in that category, adn we get a build error because of this:

arch/arm/kernel/module-plts.c:60:46: error: implicit declaration of function '__opcode_to_mem_thumb32' [-Werror=implicit-function-declaration]

This comes down to picking the wrong default, ARMv7-M uses BE8
like ARMv7-A does. Changing the default gets the kernel to compile
and presumably works.

Pull ARM SoC platform updates from Arnd Bergmann:
"The main change this time around is a cleanup of some of the oldest
platforms based on the XScale and ARM9 CPU cores, which are between 10
and 20 years old.

The Kendin/Micrel/Microchip KS8695, Winbond/Nuvoton W90x900 and Intel
IOP33x/IOP13xx platforms are removed after we determined that nobody
is using them any more.

The TI Davinci and NXP LPC32xx platforms on the other hand are still
in active use and are converted to the ARCH_MULTIPLATFORM build,
meaning that we can compile a kernel that works on these along with
most other ARMv5 platforms. Changes toward that goal are also merged
for IOP32x, but additional work is needed to complete this. Patches
for the remaining ARMv5 platforms have started but need more work and
some testing.

Support for the new ASpeed AST2600 gets added, this is based on the
Cortex-A7 ARMv7 core, and is a newer version of the existing ARMv5 and
ARMv6 chips in the same family.

Other changes include a cleanup of the ST-Ericsson ux500 platform and
the move of the TI Davinci platform to a new clocksource driver"

[ The changes had marked INTEL_IOP_ADMA and USB_LPC32XX as being
buildable on other platforms through COMPILE_TEST, but that causes new
warnings that I most definitely do not want to see during the merge
window as that could hide other issues.

So the COMPILE_TEST option got disabled for them again - Linus ]

arm: select the dma-noncoherent symbols for all swiotlb builds

We need to provide the arch hooks for non-coherent dma-direct
and swiotlb for all swiotlb builds, not just when LPAS is enabled.
Without that the Xen build that selects SWIOTLB indirectly through
SWIOTLB_XEN fails to build.

ARM: remove ks8695 platform

ks8695 is an older SoC originally made by Kendin, which was later acquired
by Micrel, and subsequently by Microchip.

The platform port was originally contributed by Andrew Victor and Ben
Dooks, and later maintained by Greg Ungerer.

When I recently submitted cleanups, but Greg noted that the platform no
longer boots and nobody is using it any more, we decided to remove it.
