ac6c9e2bed Merge branch 'safe-dirty-tlb-flush'
This merges the patch to fix possible loss of dirty bit on munmap() or
madvice(DONTNEED).  If there are concurrent writers on other CPU's that
have the unmapped/unneeded page in their TLBs, their writes to the page
could possibly get lost if a third CPU raced with the TLB flush and did
a page_mkclean() before the page was fully written.

Admittedly, if you unmap() or madvice(DONTNEED) an area _while_ another
thread is still busy writing to it, you deserve all the lost writes you
could get.  But we kernel people hold ourselves to higher quality
standards than "crazy people deserve to lose", because, well, we've seen
people do all kinds of crazy things.

So let's get it right, just because we can, and we don't have to worry
about it.

Pull irq fixes from Thomas Gleixner:
 "A slighlty large fix for a subtle issue in the CPU hotplug code of
  certain ARM SoCs, where the not yet online cpu needs to setup the cpu
  local timer and needs to set the interrupt affinity to itself.
  Setting interrupt affinity to a not online cpu is prohibited and
  therefor the timer interrupt ends up on the wrong cpu, which leads to
  nasty complications.

  The SoC folks tried to hack around that in the SoC code in some more
  than nasty ways.  The proper solution is to have a way to enforce the
  affinity setting to a not online cpu.  The core patch to the genirq
  code provides that facility and the follow up patches make use of it
  in the GIC interrupt controller and the exynos timer driver.

  The change to the core code has no implications to existing users,
  except for the rename of the locked function and therefor the
  necessary fixup in mips/cavium.  Aside of that, no runtime impact is
  possible, as none of the existing interrupt chips implements anything
  which depends on the force argument of the irq_set_affinity()
  callback"

1cf35d4771 mm: split 'tlb_flush_mmu()' into tlb flushing and memory freeing parts
The mmu-gather operation 'tlb_flush_mmu()' has done two things: the
actual tlb flush operation, and the batched freeing of the pages that
the TLB entries pointed at.

This splits the operation into separate phases, so that the forced
batched flushing done by zap_pte_range() can now do the actual TLB flush
while still holding the page table lock, but delay the batched freeing
of all the pages to after the lock has been dropped.

This in turn allows us to avoid a race condition between
set_page_dirty() (as called by zap_pte_range() when it finds a dirty
shared memory pte) and page_mkclean(): because we now flush all the
dirty page data from the TLB's while holding the pte lock,
page_mkclean() will be held up walking the (recently cleaned) page
tables until after the TLB entries have been flushed from all CPU's.

 code changes and DT changes. Aside from omap and versatile express,
 the actual code bugs are sporadic and trivial. Here is an overview:
 
   imx:
    - fix video clock settings
    - fix one clock refcounting bug
 
   omap:

   vexpress:
    - fix voltage calculation for opp
    - fix reboot hang and warning
    - fix out-of-bounds array access
    - improve error handling in clock driver
 
   overall:
    - always select CLKSRC_OF in multiplatform builds
 
 And these are the devicetree related changes:
 
   imx:
    - add missing #clock-cell properties
    - fix pinctrl setting in imx6sl-evk
    - fix video endpoint on imx53
    - remove obsolete lvds-channel nodes (multiple patches)
    - add missing second stmpe node

    - fix microsom pincontrol setting for rgmii
    - fix fatal typo in touchscreen DT usage for mx5

43683afbcb arm64: debug: remove noisy, pointless warning
Sending a SIGTRAP to a user task after execution of a BRK instruction at
EL0 is fundamental to the way in which software breakpoints work and
doesn't deserve a warning to be logged in dmesg. Whilst the warning can
be justified from EL1, do_debug_exception will already do the right thing,
so simply remove the code altogether.

2eb835e058 arm64: mm: Add THP TLB entries to general mmu_gather
When arm64 moved over to the core mmu_gather, it lost the logic to
flush THP TLB entries (tlb_remove_pmd_tlb_entry was removed and the
core implementation only signals that the mmu_gather needs a flush).

This patch ensures that tlb_add_flush is called for THP TLB entries.

Commit fdb487f5c9
  ("ARM: 8015/1: Add cpu_is_pj4 to distinguish PJ4 because it
    has some differences with V7")
introduced a cpuid check for Marvell PJ4 processors to fix a
regression caused by adding PJ4 based Marvell Dove into
multi_v7.

Unfortunately, this check is too narrow to catch PJ4 used on
Dove itself and breaks iWMMXt support.

This patch therefore relaxes the cpuid mask to match both PJ4
and PJ4B. Also, rework the given comment about PJ4/PJ4B
modifications to be a little bit more specific about the
differences.

e89f443b18 ARM: 8040/1: pj4: properly detect existence of iWMMXt coprocessor
commit fdb487f5c9
  ("ARM: 8015/1: Add cpu_is_pj4 to distinguish PJ4 because it
    has some differences with V7")
introduced a fix for checking PJ4 cpuid to not use PJ4 specific
coprocessor access on non-PJ4 platforms.

Unfortunately, this in turn broke Marvell Armada 370/XP, both
comprising Marvell PJ4B CPUs without iWMMXt extension. Instead
of only checking for cpuid, which may not be sufficient to
determine iWMMXt support, the presence of iWMMXt coprocessors
can be checked by enabling and reading the Coprocessor ID
register (wCID, register 0 of CP1).

Therefore this adds an explicit check for the presence and correct
wCID value, before enabling iWMMXt capabilities. As a bonus, also
print the iWMMXt version of a detected coprocessor.

This has been tested to properly detect iWMMXt presence/absence on:
- PJ4,  CPUID 0x560f5815, wCID 0x56052001: Marvell Dove, iWMMXt v2
- PJ4B, CPUID 0x561f5811: Marvell Armada 370, no iWMMXt
- PJ4B, CPUID 0x562f5841, wCID 0x56052001: Marvell Armada 1500, iWMMXt v2
- PJ4B, CPUID 0x562f5842: Marvell Armada XP, no iWMMXt

c2f07fe64d ARM: 8038/1: iwmmxt: explicitly check for supported architectures
iwmmxt.S requires special treatment of coprocessor access registers
for PJ4 and XScale-based CPUs. It only checks for CPU_PJ4 and drops
down to XScale-based treatment on all other architectures.

As some PJ4B also come with iWMMXt and also need PJ4 treatment,
rework the corresponding preprocessor directives to explicitly
check for supported architectures and fail on unsupported ones.

A few driver specific fixes here:
 
  - SH HSPI was dealing with its clocks incorrectly which meant it didn't
    work on some SoCs, fixing this also requires a small fix to one of
    the SoC clock trees to avoid breaking existing users.
  - The SiRF driver appears to have had several quality problems, it's
    fairly new and not widely used so this isn't too worrying.
  - A brute force fix for excessive locking in the Atmel driver, it needs
    further investigation but this deals with the immediate issue.
  - A build fix for the Blackfin driver.

fb677ef70b ARM: OMAP2+: Fix GPMC remap for devices using an offset
At least the smc91x driver expects the device to be at 0x300
offset from bus base address. This does not work currently
for GPMC when booted in device tree mode as it attempts to
remap the the allocated GPMC partition to the address
configured by the device tree plus the device offset.

Note that this works just fine when booted with legacy mode.

Let's fix the issue by just ignoring any device specific
offset while remapping. And let's make sure the remap
address confirms to the GPMC 16MB minimum granularity
as listed in the TRM for GPMC_CONFIG7 BASEADDRESS bits.

Otherwise we can get something like this:

omap-gpmc 6e000000.gpmc: cannot remap GPMC CS 1 to 0x01000300
