UART pin lists consist GPIO numbers which is simply wrong.
Replace it by pin numbers.

On the south bridge we have pin from to 29, so it gives 30 pins (and not
29).
Without this patch the kernel complain with the following traces:

Pin 23 on South bridge does not belong to the rgmii group. It belongs to
a separate group which can have 3 functions.
Due to this the fix also have to update the way the functions are
managed. Until now each groups used NB_FUNCS(which was 2) functions. For
the mpp23, 3 functions are available but it is the only group which needs
it, so on the loop involving NB_FUNCS an extra test was added to handle
only the functions added.
The bug was visible with the merge of the commit 07d065abf93d "arm64:
dts: marvell: armada-3720-db: Add vqmmc regulator for SD slot", the gpio
regulator used the gpio 23, due to this the whole rgmii group was setup
to gpio which broke the Ethernet support on the Armada 3720 DB
board. Thanks to this patch, the UHS SD cards (which need the vqmmc)
_and_ the Ethernet work again.

When we started following the backlight minimum brightness in
6dda730e55f4 ("drm/i915: respect the VBT minimum backlight brightness")
we overlooked the brightness invert quirk. Even if we invert the
brightness, we need to take the min limit into account. We probably
missed this because the invert has only been required on gen4 for proper
operation.

Commit 296e46db0073 ("MIPS: Don't unnecessarily include kmalloc.h into
<asm/cache.h>.") claimed that the inclusion of the machine's kmalloc.h
from asm/cache.h is unnecessary, but this is not true.
Without including kmalloc.h we don't get a definition for
ARCH_DMA_MINALIGN, which means we no longer suitably align DMA. Further
to this the definition of ARCH_KMALLOC_MINALIGN provided by linux/slab.h
ends up being set to the alignment of an unsigned long long value rather
than to ARCH_DMA_MINALIGN, which means that buffers allocated using
kmalloc may no longer be safely aligned for use with DMA.
Fix this by re-adding the include of kmalloc.h in asm/cache.h. This
reverts commit 296e46db0073 ("MIPS: Don't unnecessarily include
kmalloc.h into <asm/cache.h>.")

While testing cpu hoptlug (cpu down and up in loops) on kernel 4.4, it was
observed that occasionally check for cpu online will fail in kernel/cpu.c,
_cpu_up:
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git/tree/kernel/cpu.c?h=v4.4.79#n485
518 /* Arch-specific enabling code. */
519 ret = __cpu_up(cpu, idle);
520
521 if (ret != 0)
522 goto out_notify;
523 BUG_ON(!cpu_online(cpu));
Reason is race between start_secondary and _cpu_up. cpu_callin_map is set
before cpu_online_mask. In __cpu_up, cpu_callin_map is waited for, but cpu
online mask is not, resulting in race in which secondary processor started
and set cpu_callin_map, but not yet set the online mask,resulting in above
BUG being hit.
Upstream differs in the area. cpu_online check is in bringup_wait_for_ap,
which is after cpu reached AP_ONLINE_IDLE,where secondary passed its start
function. Nonetheless, fix makes start_secondary safe and not depending on
other locks throughout the code. It protects as well against cpu_online
checks put in between sometimes in the future.
Fix this by moving completion after all flags are set.

The existing sub channel code did not wait for all the sub-channels
to completely initialize. This could lead to race causing crash
in napi_netif_del() from bad list. The existing code would send
an init message, then wait only for the initial response that
the init message was received. It thought it was waiting for
sub channels but really the init response did the wakeup.
The new code keeps track of the number of open channels and
waits until that many are open.
Other issues here were:
* host might return less sub-channels than was requested.
* the new init status is not valid until after init was completed.

This patch fixes a bug associated with iscsit_reset_np_thread()

used across multiple iscsi-target instances, that would result in
hung task(s) similar to below where configfs rmdir process context

It would happen because each iscsit_reset_np_thread() sets state
to ISCSI_NP_THREAD_RESET, sends SIGINT, and then blocks waiting
for completion on iscsi_np->np_restart_comp.
However, if iscsi_np was active processing a login request and
more than a single iscsit_reset_np_thread() caller to the same
iscsi_np was blocked on iscsi_np->np_restart_comp, iscsi_np
kthread process context in __iscsi_target_login_thread() would
flush pending signals and only perform a single completion of
np->np_restart_comp before going back to sleep within transport
specific iscsit_transport->iscsi_accept_np code.
To address this bug, add a iscsi_np->np_reset_count and update
__iscsi_target_login_thread() to keep completing np->np_restart_comp
until ->np_reset_count has reached zero.

The latest change of compat_sys_sigpending in commit 8f13621abced
("sigpending(): move compat to native") has broken it in two ways.
First, it tries to write 4 bytes more than userspace expects:
sizeof(old_sigset_t) == sizeof(long) == 8 instead of
sizeof(compat_old_sigset_t) == sizeof(u32) == 4.
Second, on big endian architectures these bytes are being written in the
wrong order.
This bug was found by strace test suite.

ext4_xattr_inode_read() currently reads each block sequentially while
waiting for io operation to complete before moving on to the next
block. This prevents request merging in block layer.
Add a ext4_bread_batch() function that starts reads for all blocks
then optionally waits for them to complete. A similar logic is used
in ext4_find_entry(), so update that code to use the new function.

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
mount /dev/sdb /mnt/sdb
touch /mnt/sdb/{x,y}
setfattr -n user.1 -v aaa /mnt/sdb/x
setfattr -n user.2 -v bbb /mnt/sdb/x
setfattr -n user.1 -v aaa /mnt/sdb/y
setfattr -n user.2 -v bbb /mnt/sdb/y
debugfs -R 'stat x' /dev/sdb | cat
debugfs -R 'stat y' /dev/sdb | cat
This patch defers the reinsertion to the cache so that we can locate
other blocks with the same contents.

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.

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.

ext4_find_unwritten_pgoff() does not properly handle a situation when
starting index is in the middle of a page and blocksize < pagesize. The
following command shows the bug on filesystem with 1k blocksize:
xfs_io -f -c "falloc 0 4k" \
-c "pwrite 1k 1k" \
-c "pwrite 3k 1k" \
-c "seek -a -r 0" foo
In this example, neither lseek(fd, 1024, SEEK_HOLE) nor lseek(fd, 2048,
SEEK_DATA) will return the correct result.
Fix the problem by neglecting buffers in a page before starting offset.

This fixes a problem where the system gets stuck in a loop
unable to wakeup via power button in s2idle.
The problem happens because:
- press power button:
- system emits 0xc0 (power press), event ignored
- system emits 0xc1 (power release), event processed,
emited as KEY_POWER
- set wakeup_mode to true
- system goes to s2idle
- press power button
- system emits 0xc0 (power press), wakeup_mode is true,
system wakes
- system emits 0xc1 (power release), event processed,
emited as KEY_POWER
- system goes to s2idle again
To avoid this situation, process the presses (which matches what
intel-hid does too).

Pull media fixes from Mauro Carvalho Chehab:
"This series is larger than I would like to submit for -rc4. My
original intent were to sent it to either -rc2 or -rc3. Unfortunately,
due to my vacations, I got a lot of pending stuff after my return, and
had to do some biz trips, with prevented me to send this earlier.
Several fixes:
- some fixes at atomisp staging driver
- several gcc 7 warning fixes
- cleanup media SVG files, in order to fix PDF build on some distros
- fix random Kconfig build of venus driver
- some fixes for the venus driver
- some changes from semaphone to mutex in ngene's driver
- some locking fixes at dib0700 driver
- several fixes on ngene's driver and frontends to make it properly
support some new boards added on Kernel 4.13
- some fixes to CEC drivers
- omap_vout: vrfb: convert to dmaengine
- docs-rst: document EBUSY for VIDIOC_S_FMT
Please notice that the big diffstat changes here are at the SVG files.
Visually, the images look the same, but the file size is now a lot
smaller than before, and they don't use some XML tags that would cause
them to be badly parsed by some ImageMagick versions, or to require a
lot of memory by TeTex, with would break PDF output on some
distributions"

We've changed the discard command handling into parallel manner.
But, in this change, I forgot decreasing the usage count of the bio
which was used to send discard request. I'm sorry about that.

- stm32: fix the kernel build by selecting the hierarchical irqdomain
symbol properly - this happens to be done in the pin control

Pull clk fixes from Stephen Boyd:
"A handful of critical fixes for changes introduce this merge window.
- The TI sci_clk_get() API was pretty broken and nobody noticed.
- There were some CPUfreq crashes on C.H.I.P devices because we
failed to propagate rates up the clk tree.
- Also, the Intel Atom PMC clk driver needs to mark a clk critical if
the firmware has it enabled already so that audio doesn't get
killed on Baytrail.
- Gemini devices have a dead serial console because the reset control
usage in the serial driver assume one method of reset that gemini
doesn't support (this will be fixed in the next version in the
reset framework so this is the small fix for -rc series).
- Finally we have two rate calculation fixes, one for Exynos and one
for Meson SoCs, that fix rate inconsistencies"

We really must check with #if __BYTE_ORDER == XYZ instead of
just presence of #ifdef __LITTLE_ENDIAN. I noticed that when
actually running this on big endian machine, the latter test
resolves to true for user space, same for #ifdef __BIG_ENDIAN.
E.g., looking at endian.h from libc, both are also defined
there, so we really must test this against __BYTE_ORDER instead
for proper insns selection. For the kernel, such checks are
fine though e.g. see 13da9e200fe4 ("Revert "endian: #define
__BYTE_ORDER"") and 415586c9e6d3 ("UAPI: fix endianness conditionals
in M32R's asm/stat.h") for some more context, but not for
user space. Lets also make sure to properly include endian.h.
After that, suite passes for me:

Pull ARM SoC fixes from Arnd Bergmann:
"This comes a bit later than I planned, and as a consequence is a
larger than it should be.
Most of the changes are devicetree fixes, across lots of platforms:
Renesas, Samsung Exynos, Marvell EBU, TI OMAP, Rockchips, Amlogic
Meson, Sigma Desings Tango, Allwinner SUNxi and TI Davinci.
Also across many platforms, I applied an older series of simple
randconfig build fixes. This includes making the CONFIG_MTD_XIP option
compile again, which had been broken for many years and probably has
not been missed, but it felt wrong to just remove it completely.
The only other changes are:
- We enable HWSPINLOCK in defconfig to get some Qualcomm boards to
work out of the box.
- A few regression fixes for Texas Instruments OMAP2+.
- A boot regression fix for the Renesas regulator quirk.
- A suspend/resume fix for Uniphier SoCs, fixing the resume of the
system bus"

According to the commit that implemented per-inode DAX flag:
commit 58f88ca2df72 ("xfs: introduce per-inode DAX enablement")
the flag is supposed to act as "inherit flag".
Currently this only works in the situations where parent directory
already has a flag in di_flags set, otherwise inheritance does not
work. This is because setting the XFS_DIFLAG2_DAX flag is done in a
wrong branch designated for di_flags, not di_flags2.
Fix this by moving the code to branch designated for setting di_flags2,
which does test for flags in di_flags2.

The bio describing discard operation is allocated by
__blkdev_issue_discard() which returns us a reference to it. That
reference is never released and thus we leak this bio. Drop the bio
reference once it completes in xlog_discard_endio().
