ARM: 8129/1: errata: work around Cortex-A15 erratum 830321 using dummy strex

On revisions of Cortex-A15 prior to r3p3, a CLREX instruction at PL1 may
falsely trigger a watchpoint exception, leading to potential data aborts
during exception return and/or livelock.

This patch resolves the issue in the following ways:

- Replacing our uses of CLREX with a dummy STREX sequence instead (as
we did for v6 CPUs).

- Removing the clrex code from v7_exit_coherency_flush and derivatives,
since this only exists as a minor performance improvement when
non-cached exclusives are in use (Linux doesn't use these).

Benchmarking on a variety of ARM cores revealed no measurable
performance difference with this change applied, so the change is
performed unconditionally and no new Kconfig entry is added.

Merge branch 'for-linus' of git://ftp.arm.linux.org.uk/~rmk/linux-arm

Pull ARM updates from Russell King:
"Included in this update:

- perf updates from Will Deacon:

The main changes are callchain stability fixes from Jean Pihet and
event mapping and PMU name rework from Mark Rutland

The latter is preparatory work for enabling some code re-use with
arm64 in the future.

- updates for nommu from Uwe Kleine-König:

Two different fixes for the same problem making some ARM nommu
configurations not boot since 3.6-rc1. The problem is that
user_addr_max returned the biggest available RAM address which
makes some copy_from_user variants fail to read from XIP memory.

- deprecate legacy OMAP DMA API, in preparation for it's removal.

The popular drivers have been converted over, leaving a very small
number of rarely used drivers, which hopefully can be converted
during the next cycle with a bit more visibility (and hopefully
people popping out of the woodwork to help test)

- more tweaks for BE systems, particularly with the kernel image
format. In connection with this, I've cleaned up the way we
generate the linker script for the decompressor.

- removal of hard-coded assumptions of the kernel stack size, making
everywhere depend on the value of THREAD_SIZE_ORDER.

- MCPM updates from Nicolas Pitre.

- Make it easier for proper CPU part number checks (which should
always include the vendor field).

- Assembly code optimisation - use the "bx" instruction when
returning from a function on ARMv6+ rather than "mov pc, reg".

- Save the last kernel misaligned fault location and report it via
the procfs alignment file.

- Clean up the way we create the initial stack frame, which is a
repeated pattern in several different locations.

- Support for 8-byte get_user(), needed for some DRM implementations.

- mcs locking from Will Deacon.

- Save and restore a few more Cortex-A9 registers (for errata
workarounds)

- Fix various aspects of the SWP emulation, and the ELF hwcap for the
SWP instruction.

- Update LPAE logic for pte_write and pmd_write to make it more
correct.

- Support for Broadcom Brahma15 CPU cores.

- ARM assembly crypto updates from Ard Biesheuvel"

Merge tag 'please-pull-apei' into x86/ras

APEI is currently implemented so that it depends on x86 hardware.
The primary dependency is that GHES uses the x86 NMI for hardware
error notification and MCE for memory error handling. These patches
remove that dependency.

Other APEI features such as error reporting via external IRQ, error
serialization, or error injection, do not require changes to use them
on non-x86 architectures.

The following patch set eliminates the APEI Kconfig x86 dependency
by making these changes:
- treat NMI notification as GHES architecture - HAVE_ACPI_APEI_NMI
- group and wrap around #ifdef CONFIG_HAVE_ACPI_APEI_NMI code which
is used only for NMI path
- identify architectural boxes and abstract it accordingly (tlb flush and MCE)
- rework ioremap for both IRQ and NMI context

NMI code is kept in ghes.c file since NMI and IRQ context are tightly coupled.

Note, these patches introduce no functional changes for x86. The NMI notification
feature is hard selected for x86. Architectures that want to use this
feature should also provide NMI code infrastructure.

ARM: EXYNOS: Refactored code for using PMU address via DT

Under "arm/mach-exynos" many files are using PMU register offsets.
Since we have added support for accessing PMU base address via DT,
now we can remove PMU mapping from exynosX_iodesc. Let's convert
all these access using iomapped address.
This will help us in removing static mapping of PMU base address
as well as help in reducing dependency over machine header files.
Thus helping for migration of PMU implementation from machine to
driver folder which can be reused for ARM64 based SoC.

Also as we have removed static mappings from "regs-pmu.h" it does
not need map.h anymore. But "platsmp.c" needed this and till now it
got included indirectly. So lets move header inclusion of
"mach/map.h" from "regs-pmu.h" to "platsmp.c".

ARM: EXYNOS: Support cluster power off on exynos5420/5800

Turning off a cluster when all 4 cores of the cluster are powered off
saves power significantly. Powering off the A15 L2 alone gives around
100mW in savings. Add support for powering off the A15/A7 clusters on
exynos5420/5800.

The patch enables specific register bits which ensure that:
- cluster L2 will be turned on before the first man is powered up.
- last man will be turned off before the cluster L2 is turned off.
- core is powered down before powering it up.

Remove the exynos_cluster_power_control function completely as we can
rely on the above mentioned bits rather than polling the cluster power
status register.
