Removal of the deprectated num-slots property from all Rockchip dw-mmc
nodes. The rv1108 gains support for sd-cards on the evaluation board and
the general nodes get a bit of cosmetic. On rk3288 the evb gains support
saradc and the adc-key connected to it while some more boards also get
their mali gpu enabled (fennec, evb, tinker).
The biggest set of changes can be found on the rk3228/rk3229 combo this
time. It gets core support for efuse, sdmmc, sdio, io-domans and spdif
as well as a separate rk3229.dtsi that will keep the slight differences
between the two brothers rk3228/rk3229. The evaluation board also gets
some attention and abled nodes (regulators, io-domains, emmc, tsadc keys)
But I think the most interesting change is the cpu enable-method for it.
Instead of using the older in-kernel method, we're now also moving to
handling this in firmware via the psci interface on 32bit Rockchip socs.
In a recently merged pull request [0] support for the rk3228/rk3229 was
added to OP-TEE including the psci support and it seems supporting other
32bit Rockchip socs that way is also planned for the future.

* Add pin controller support to the RZ/G1M (r8a7743) SoC and

* Add GPIO support to the RZ/G1M (r8a7743) SoC now that the driver
is availabe in v4.13-rc1.
* Enable MMCIF0 and Ethernet AVB support on the RZ/G1M (r8a7743) SoC and
the iWave-RZG1M-20M Qseven SOM. This depends on newly added pin
controller support noted above.
* Use R-Car Gen 2 fallback binding for vin nodes
This makes binding use consistent across R-Car Gen 2 SoCs.
It does not have any run-time effect
* Use SMP jump stub SRAM region from DT on R-Car Gen 2 SoCs
Geert Uytterhoeven says, "The R-Car Gen2 platform code for CPU core
bringup needs to copy a jump stub to on-SoC SRAM. Currently it uses a
hardcoded address pointing to ICRAM1."
* Add Inter Connect RAM to R-Car Gen 2 and RZ/G1 SoCs
Geert Uytterhoeven says, "R-Car Gen2 and RZ/G1 SoCs contain two or three
blocks of SRAM, which can be used for several purposes. One such purpose
is holding a jump stub for CPU core bringup."
* Use generic compatible string for I2C EEPROM for RZ/A1 (r7s72100) SoC
and koelsch board.

ext4: inplace xattr block update fails to deduplicate blocks
When an xattr block has a single reference, block is updated inplace
and it is reinserted to the cache. Later, a cache lookup is performed
to see whether an existing block has the same contents. This cache
lookup will most of the time return the just inserted entry so
deduplication is not achieved.
Running the following test script will produce two xattr blocks which
can be observed in "File ACL: " line of debugfs output:
mke2fs -b 1024 -I 128 -F -O extent /dev/sdb 1G

ext4: fix warning about stack corruption
After commit
62d1034f53e3 ("fortify: use WARN instead of BUG for now"),
we get a warning about possible stack overflow from a memcpy that
was not strictly bounded to the size of the local variable:
inlined from 'ext4_mb_seq_groups_show' at fs/ext4/mballoc.c:2322:2:
include/linux/string.h:309:9: error: '__builtin_memcpy': writing between 161 and 1116 bytes into a region of size 160 overflows the destination [-Werror=stringop-overflow=]
We actually had a bug here that would have been found by the warning,
but it was already fixed last year in commit
30a9d7afe70e ("ext4: fix
stack memory corruption with 64k block size").
This replaces the fixed-length structure on the stack with a variable-length
structure, using the correct upper bound that tells the compiler that
everything is really fine here. I also change the loop count to check
for the same upper bound for consistency, but the existing code is
already correct here.
Note that while clang won't allow certain kinds of variable-length arrays
in structures, this particular instance is fine, as the array is at the
end of the structure, and the size is strictly bounded.

ext4: fix dir_nlink behaviour
The dir_nlink feature has been enabled by default for new ext4
filesystems since e2fsprogs-1.41 in 2008, and was automatically
enabled by the kernel for older ext4 filesystems since the
dir_nlink feature was added with ext4 in kernel 2.6.28+ when
the subdirectory count exceeded EXT4_LINK_MAX-1.
Automatically adding the file system features such as dir_nlink is
generally frowned upon, since it could cause the file system to not be
mountable on older kernel, thus preventing the administrator from
rolling back to an older kernel if necessary.
In this case, the administrator might also want to disable the feature
because glibc's fts_read() function does not correctly optimize
directory traversal for directories that use st_nlinks field of 1 to
indicate that the number of links in the directory are not tracked by
the file system, and could fail to traverse the full directory
hierarchy. Fortunately, in the past ten years very few users have
complained about incomplete file system traversal by glibc's
fts_read().
This commit also changes ext4_inc_count() to allow i_nlinks to reach
the full EXT4_LINK_MAX links on the parent directory (including "."
and "..") before changing i_links_count to be 1.

ARM: dts: sun8i: a83t: Add device node for R_INTC interrupt controller
The R_INTC interrupt controller handles the NMI interrupt pin for the
SoC. While there is no documentation or code from the vendor for this
device on the A83T, existing mainline kernel drivers and bindings show
this to be similar to the old Allwinner interrupt controller found on
the A10 SoC, but with only the NMI interrupt wired. Register poking
experiments confirm this.
The device seems to be the same across all recent Allwinner SoCs, apart
from the A20 and A80, which have a separate set of registers to handle
the NMI interrupt. We already have a set of bindings supporting this
on the A31.
Add a device node for it, with an SoC specific compatible.

arm64: Fix potential race with hardware DBM in ptep_set_access_flags()
In a system with DBM (dirty bit management) capable agents there is a
possible race between a CPU executing ptep_set_access_flags() (maybe
non-DBM capable) and a hardware update of the dirty state (clearing of
PTE_RDONLY). The scenario:
a) the pte is writable (PTE_WRITE set), clean (PTE_RDONLY set) and old
(PTE_AF clear)
b) ptep_set_access_flags() is called as a result of a read access and it
needs to set the pte to writable, clean and young (PTE_AF set)
c) a DBM-capable agent, as a result of a different write access, is
marking the entry as young (setting PTE_AF) and dirty (clearing
PTE_RDONLY)
The current ptep_set_access_flags() implementation would set the
PTE_RDONLY bit in the resulting value overriding the DBM update and
losing the dirty state.
This patch fixes such race by setting PTE_RDONLY to the most permissive
(lowest value) of the current entry and the new one.

Fix deadlock in regulator quirk for R-Car Gen 2 SoCs
The da9063/da9210 regulator quirk for R-Car Gen2 boards uses a bus
notifier, and unregisters the notifier when it is no longer needed.
However, a notifier must not be unregistered from within the call chain.
This bug went unnoticed, as blocking_notifier_chain_unregister() didn't
take the semaphore during early boot. This is no longer the case as of
upstream commit
1c3c5eab171590f8 ("sched/core: Enable might_sleep() and
smp_processor_id() checks early") and a deadlock occurs.

powerpc/64: Fix __check_irq_replay missing decrementer interrupt
If the decrementer wraps again and de-asserts the decrementer
exception while hard-disabled, __check_irq_replay() has a test to
notice the wrap when interrupts are re-enabled.
The decrementer check must be done when clearing the PACA_IRQ_HARD_DIS
flag, not when the PACA_IRQ_DEC flag is tested. Previously this worked
because the decrementer interrupt was always the first one checked
after clearing the hard disable flag, but HMI check was moved ahead of
that, which introduced this bug.
This can cause a missed decrementer interrupt if we soft-disable
interrupts then take an HMI which is recorded in irq_happened, then
hard-disable interrupts for > 4s to wrap the decrementer.
