get_new_mmu_context() accepts a cpu argument, but implicitly assumes
that this is always equal to smp_processor_id() by operating on the
local CPU's TLB & icache.
Remove the cpu argument and have get_new_mmu_context() call
smp_processor_id() instead.

The drop_mmu_context() function accepts a cpu argument, but it
implicitly expects that this is always equal to smp_processor_id() by
allocating & configuring an ASID on the local CPU when the mm is active
on the CPU indicated by the cpu argument.
All callers do provide the value of smp_processor_id() to the cpu
argument.
Remove the redundant argument and have drop_mmu_context() call
smp_processor_id() itself, making it clearer that the cpu variable
always represents the local CPU.

MIPS has separate definitions of activate_mm() & switch_mm() which are
identical apart from switch_mm() checking that the ASID is valid before
acquiring a new one.
We know that when activate_mm() is called cpu_context(X, mm) will be
zero, and this will never be considered a valid ASID because we never
allow the ASID version number to be zero, instead beginning with version
1 using asid_first_version(). Therefore switch_mm() will always allocate
a new ASID when called for a new task, meaning that it will behave
identically to activate_mm().
Take advantage of this to remove the duplication & define activate_mm()
using switch_mm() just like many other architectures do.

This line is weird in multiple ways.
(CONFIG_GENERIC_CSUM) might be a typo of $(CONFIG_GENERIC_CSUM).
Even if you add '$' to it, $(CONFIG_GENERIC_CSUM) is never evaluated
to 'y' because scripts/Makefile.asm-generic does not include
include/config/auto.conf. So, the asm-generic wrapper of checksum.h
is never generated.
Even if you manage to generate it, it is never included by anyone
because MIPS has the checkin header with the same file name:
arch/mips/include/asm/checksum.h
As you see in the top Makefile, the checkin headers are included before
generated ones.
LINUXINCLUDE := \
-I$(srctree)/arch/$(SRCARCH)/include \
-I$(objtree)/arch/$(SRCARCH)/include/generated \
...
Commit 4e0748f5beb9 ("MIPS: Use generic checksum functions for MIPS R6")
already added the asm-generic fallback code in the checkin header:
#ifdef CONFIG_GENERIC_CSUM
#include <asm/generic/checksum.h>
#else
...
#endif

dma_sync_phys() is only called for some CPUs when a mapping is removed.
Add ARCH_HAS_SYNC_DMA_FOR_CPU only for the CPUs listed in
cpu_needs_post_dma_flush() which need this extra call and do not compile
this code in for other CPUs. We need this for R10000, R12000, BMIPS5000
CPUs and CPUs supporting MAAR which was introduced in MIPS32r5.

UNAME26 is a mechanism to report Linux's version as 2.6.x, for
compatibility with old/broken software. Due to the way it is
implemented, it would have to be updated after 5.0, to keep the
resulting versions unique. Linus Torvalds argued:
"Do we actually need this?
I'd rather let it bitrot, and just let it return random versions. It
will just start again at 2.4.60, won't it?
Anybody who uses UNAME26 for a 5.x kernel might as well think it's
still 4.x. The user space is so old that it can't possibly care about
differences between 4.x and 5.x, can it?
The only thing that matters is that it shows "2.4.<largeenough>",
which it will do regardless"

Pull ARM SoC fixes from Olof Johansson:
"A bigger batch than I anticipated this week, for two reasons:
- Some fallout on Davinci from board file -> DTB conversion, that
also includes a few longer-standing fixes (i.e. not recent
regressions).
- drivers/reset material that has been in linux-next for a while, but
didn't get sent to us until now for a variety of reasons
(maintainer out sick, holidays, etc). There's a functional
dependency in there such that one platform (Altera's SoCFPGA) won't
boot without one of the patches; instead of reverting the patch
that got merged, I looked at this set and decided it was small
enough that I'll pick it up anyway. If you disagree I can revisit
with a smaller set.
That being said, there's also a handful of the usual stuff:
- Fix for a crash on Armada 7K/8K when the kernel touches
PSCI-reserved memory
- Fix for PCIe reset on Macchiatobin (Armada 8K development board,
what this email is sent from in fact :)

mvebu fixes for 5.0
They are all device tree fixes which also worth being in stable:
- Reserve PSCI area on Armada 7K/8K preventing the kernel accessing
this area and crashing while doing it.
- Use correct PCIe reset signal on MACCHIATOBin (Armada 8040 based)
- Fix polarity of GPIO fan line D-Link DNS NASes(kikwood based)

Commit 49e54187ae0b ("ata: libahci_platform: comply to PHY framework") uses
the PHY_MODE_SATA, but that enum had not yet been added. This caused a
build failure for me, with today's linux.git.
Also, there is a potentially conflicting (mis-named) PHY_MODE_SATA, hiding
in the Marvell Berlin SATA PHY driver.
Fix the build by:
1) Renaming Marvell's defined value to a more scoped name,
in order to avoid any potential conflicts: PHY_BERLIN_MODE_SATA.
2) Adding the missing enum, which was going to be added anyway as part
of [1].

git://git.infradead.org/users/hch/dma-mapping
Pull dma_zalloc_coherent() removal from Christoph Hellwig:
"We've always had a weird situation around dma_zalloc_coherent. To
safely support mapping the allocations to userspace major
architectures like x86 and arm have always zeroed allocations from
dma_alloc_coherent, but a couple other architectures were missing that
zeroing either always or in corner cases.
Then later we grew anothe dma_zalloc_coherent interface to explicitly
request zeroing, but that just added __GFP_ZERO to the allocation
flags, which for some allocators that didn't end up using the page
allocator ended up being a no-op and still not zeroing the
allocations.
So for this merge window I fixed up all remaining architectures to
zero the memory in dma_alloc_coherent, and made dma_zalloc_coherent a
no-op wrapper around dma_alloc_coherent, which fixes all of the above
issues.
dma_zalloc_coherent is now pointless and can go away, and Luis helped
me writing a cocchinelle script and patch series to kill it, which I
think we should apply now just after -rc1 to finally settle these
issue"

A feature has been added in the libahci driver: the possibility to set
a new flag in hpriv->flags to let the core handle PHY suspend/resume
automatically. Make use of this feature to make suspend to RAM work
with SATA drives on A3700.
