1899de2894 ARM: S3C24XX: use generic DEBUG_UART_PHY/_VIRT in debug macro

daf67dfc59 ARM: S3C24XX: trim down debug uart handling
Using the lowlevel debug uart is a corner case - even more so in a
multiplatform environment. So it seems reasonable to simply let the
developer set the appropriate uart type for the debugged SoC.

d8b532578f ARM: S3C24XX: cpufreq-utils: don't write raw values to MPLLCON when using ccf
The s3c24xx cpufreq driver needs to change the mpll speed and was doing
this by writing raw values from a translation table into the MPLLCON
register.

Change this to use a regular clk_set_rate call when using the common
clock framework and only write the raw value in the samsung_clock case.

The s3c cpufreq driver does already aquire the mpll, so simply add a reference
to struct s3c_cpufreq_config to let set_fvco access it.

While struct clk is opaque the differenciation between samsung clock and
common clock is kept, as the samsung-clock mpll clk does not implement a
real set_rate.

5d4e08c45a arm: KVM: fix possible misalignment of PGDs and bounce page
The kvm/mmu code shared by arm and arm64 uses kalloc() to allocate
a bounce page (if hypervisor init code crosses page boundary) and
hypervisor PGDs. The problem is that kalloc() does not guarantee
the proper alignment. In the case of the bounce page, the page sized
buffer allocated may also cross a page boundary negating the purpose
and leading to a hang during kvm initialization. Likewise the PGDs
allocated may not meet the minimum alignment requirements of the
underlying MMU. This patch uses __get_free_page() to guarantee the
worst case alignment needs of the bounce page and PGDs on both arm
and arm64.

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

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.

Some Marvell PJ4B CPUs also implement iWMMXt extensions. With a
proper check for iWMMXt coprocessors now in place, enable it by
default on PJ4B. While at it, also allow to manually select

cd1711709f ARM: 8041/1: pj4: fix cpu_is_pj4 check
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.

ff1e5b447e spi: Fixes for v3.15
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.

Merge tag 'omap-for-v3.15/fixes-v2-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes

Fixes for omaps, mostly to fix some GPMC, DSS and USB issues for
device tree based booting. And turns out BeagleBoard xM A/B
needs it's own minimal dts in addition to the related u-boot
changes. Also few minor documentation and typo fixes are merged
to get them out of the way.
