The first variants of Armada XP SoCs (A0 stepping) have issues related
to the i2c controller which prevent to use the offload mechanism and
lead to a kernel hang during boot.
This commit add quirk in the mvebu platform code to check the SoC
version and then update the compatible string for the i2c controller
according to the revision of the SoC. Currently only some OpenBlocks
AX3-4 boards are known to use an A0 revision so the check is done only
for these boards.

All the mvebu SoCs have information related to their variant and
revision that can be read from the PCI control register.
This patch adds support for Armada XP and Armada 370. This reading of
the revision and the ID are done before the PCI initialization to
avoid any conflicts. Once these data are retrieved, the resources are
freed to let the PCI subsystem use it.

Signed-off-by: Kevin Hilman <khilman@linaro.org>

The summary interrupt is #16 in the SPI space. Unfortunately,
when this device was translated from board files to DT we forgot
to subtract 16 from the interrupt number to translate it into a
SPI interrupt. Also, the register space is larger than 4k, increase
it appropriately so that the gpio driver doesn't try to access
registers outside of its mapping.

The device tree sent upstream for exynos5250-snow encoded the search
key as CAPSLK. However in all ChromeOS kernels it is L_META. One can
certainly have long debates about which it ought to be, but I'm
proposing setting it to L_META because:
* That's how _all_ ChromeOS kernels do it and will do it.
* There is no L_META key on the board, so it's nice to have.
* For those people who really want it to be caps lock, they can use
xmodmap or somesuch.

Commit 8f34a1da35ae ("arm64: ptrace: use HW_BREAKPOINT_EMPTY type for
disabled breakpoints") fixed an issue with GDB trying to zero breakpoint
control registers. The problem there is that the arch hw_breakpoint code
will attempt to create a (disabled), execute breakpoint of length 0.
This will fail validation and report unexpected failure to GDB. To avoid
this, we treated disabled breakpoints as HW_BREAKPOINT_EMPTY, but that
seems to have broken with recent kernels, causing watchpoints to be
treated as TYPE_INST in the core code and returning ENOSPC for any
further breakpoints.
This patch fixes the problem by prioritising the `enable' field of the
breakpoint: if it is cleared, we simply update the perf_event_attr to
indicate that the thing is disabled and don't bother changing either the
type or the length. This reinforces the behaviour that the breakpoint
control register is essentially read-only apart from the enable bit
when disabling a breakpoint.

E.g. landisk_defconfig, which has CONFIG_NTFS_FS=m:
ERROR: "__ashrdi3" [fs/ntfs/ntfs.ko] undefined!
For "lib-y", if no symbols in a compilation unit are referenced by other
units, the compilation unit will not be included in vmlinux. This
breaks modules that do reference those symbols.
Use "obj-y" instead to fix this.
http://kisskb.ellerman.id.au/kisskb/buildresult/8838077/
This doesn't fix all cases. There are others, e.g. udivsi3.
This is also not limited to sh, many architectures handle this in the
same way.
A simple solution is to unconditionally include all helper functions.
A more complex solution is to make the choice of "lib-y" or "obj-y" depend
on CONFIG_MODULES:
obj-$(CONFIG_MODULES) += ...
lib-y($CONFIG_MODULES) += ...

There are a few subtle races, between change_protection_range (used by
mprotect and change_prot_numa) on one side, and NUMA page migration and
compaction on the other side.
The basic race is that there is a time window between when the PTE gets
made non-present (PROT_NONE or NUMA), and the TLB is flushed.
During that time, a CPU may continue writing to the page.
This is fine most of the time, however compaction or the NUMA migration
code may come in, and migrate the page away.
When that happens, the CPU may continue writing, through the cached
translation, to what is no longer the current memory location of the
process.
This only affects x86, which has a somewhat optimistic pte_accessible.
All other architectures appear to be safe, and will either always flush,
or flush whenever there is a valid mapping, even with no permissions
(SPARC).
The basic race looks like this:
CPU A CPU B CPU C
load TLB entry
make entry PTE/PMD_NUMA
fault on entry
read/write old page
start migrating page
change PTE/PMD to new page
read/write old page [*]
flush TLB
reload TLB from new entry
read/write new page
lose data
[*] the old page may belong to a new user at this point!
The obvious fix is to flush remote TLB entries, by making sure that
pte_accessible aware of the fact that PROT_NONE and PROT_NUMA memory may
still be accessible if there is a TLB flush pending for the mm.
This should fix both NUMA migration and compaction.

Base pages are unmapped and flushed from cache and TLB during normal
page migration and replaced with a migration entry that causes any
parallel NUMA hinting fault or gup to block until migration completes.
THP does not unmap pages due to a lack of support for migration entries
at a PMD level. This allows races with get_user_pages and
get_user_pages_fast which commit 3f926ab945b6 ("mm: Close races between
THP migration and PMD numa clearing") made worse by introducing a
pmd_clear_flush().
This patch forces get_user_page (fast and normal) on a pmd_numa page to
go through the slow get_user_page path where it will serialise against
THP migration and properly account for the NUMA hinting fault. On the
migration side the page table lock is taken for each PTE update.

Commit caaa4c804fae ("KVM: PPC: Book3S HV: Fix physical address

getting dropped in the case where the guest is creating a 4k HPTE
and the host page size is 64k. By getting the low-order bits from
hva rather than gpa we miss out on bits 12 - 15 in this case, since
hva is at page granularity. This puts the missing bits back in.

Commit e30b06f4d5f000c31a7747a7e7ada78a5fd419a1 (ARM: OMAP2+: Remove
legacy mux code for display.c) removed non-DT DSI and HDMI pinmuxing.
However, DSI pinmuxing is still needed, and removing that caused DSI
displays not to work.
This reverts the DSI parts of the commit.

"This is a pretty small batch:
The biggest single change is to stop using EFI time services on 32-bit
platforms. This matches our current behavior on 64-bit platforms as
we already had ruled them out there as being too unreliable. Turns
out that affects 32-bit platforms, too.
One NULL pointer fix for SGI UV.
Two minor build fixes, one of which only affects icc and the other
which affects icc and future versions or nonstandard default settings
of gcc"

As per the timing information for supported panel, the value should
be between 47.2 MHz to 47.9 MHz for 60Hz refresh rate.
Total horizontal pixels = 1024 (x-res) + 80 (margin) + 48 (hsync) = 1152
Total vertical pixels = 600 (y-res) + 80 (margin) + 3 (vsync) = 683
Target pixel clock rate for refresh rate @60 Hz
= 1152 * 683 * 60 = 47208960 Hz ~ 47.5 MHz

Commit
4178bac ARM: call of_clk_init from default time_init handler
added implicit call to of_clk_init() from default time_init callback,
but it did not change platforms calling it from other callbacks, despite
of not having custom time_init callbacks. This caused double clock
initialization on such platforms, leading to boot failures. An example
of such platform is mach-s3c64xx.
This patch fixes boot failure on s3c64xx by dropping custom init_irq
callback, which had a call to of_clk_init() and moving system reset
initialization to init_machine callback. This allows us to have
clocks initialized properly without a need to have custom init_time or
init_irq callbacks.
