This series contains two omap1 ams-delta GPIO clean-up patches to get
started with removal of hard-coded GPIO numbers from drivers. And then
the removal of board mach includes from drivers. The second patch mostly
touches the ams-delta audio driver but is included here because of the
removal of the latch gpios and is acked by Mark Brown.
And there are two more am437x related PM patches to save and restore
control module and timer registers for RTC only suspend mode. Looks like
the patch title for the timer changes is a bit misleading, not all the
timer code is yet living under drivers/clocksource. But I had already

ASoC: ams_delta: use GPIO lookup table
Now as the Amstrad Delta board provides GPIO lookup tables, switch from
GPIO numbers to GPIO descriptors and use the table to locate required
GPIO pins.
The card uses two pins, one for jack and the other for voice modem
codec DAI control.
For jack pin, remove hardcoded GPIO number and use GPIO descriptor
based variant of jack GPIO initialization.
For modem_codec pin, declare static variable for storing its GPIO
descriptor, obtain it on card initialization and replace obsolete
ams_delta_latch2_write() with gpiod_set_value(). For that to work,
don't request the modem_codec pin from the board init code anymore.
If the modem_codec GPIO lookup fails, skip initialization of
functionality of the card which depends on its availability.
Pin naming used by the driver should be followed while respective GPIO
lookup table is initialized by a board init code.

ARM: OMAP1: ams-delta: add GPIO lookup tables
Scope of the change is limited to GPIO pins used by board specific
device drivers which will be updated by follow-up patches of the
series. Those are some OMAP GPIO (gpio-0-15) and most of Amstrad Delta
latch2 GPIO bank pins. Remaining pins of those banks, as well as
Amstrad Delta latch1 pins, will be addressed later.
Assign a label ("latch2") to the bank, enumerate its pins and put that
information, together with OMAP GPIO bank pins, in GPIO lookup tables.
Assign lookup tables to devices as soon as those devices are registered
and their names can be obtained.
A step froward in:
- removal of hard-coded GPIO numbers from drivers,
- removal of board mach includes from drivers,
- switching to dynamically assigned GPIO numbers.

Revert "sched/numa: Delay retrying placement for automatic NUMA balance after wake_affine()"
This reverts commit
7347fc87dfe6b7315e74310ee1243dc222c68086.
Srikar Dronamra pointed out that while the commit in question did show
a performance improvement on ppc64, it did so at the cost of disabling
active CPU migration by automatic NUMA balancing which was not the intent.
The issue was that a serious flaw in the logic failed to ever active balance
if SD_WAKE_AFFINE was disabled on scheduler domains. Even when it's enabled,
the logic is still bizarre and against the original intent.
Investigation showed that fixing the patch in either the way he suggested,
using the correct comparison for jiffies values or introducing a new
numa_migrate_deferred variable in task_struct all perform similarly to a
revert with a mix of gains and losses depending on the workload, machine
and socket count.
The original intent of the commit was to handle a problem whereby
wake_affine, idle balancing and automatic NUMA balancing disagree on the
appropriate placement for a task. This was particularly true for cases where
a single task was a massive waker of tasks but where wake_wide logic did
not apply. This was particularly noticeable when a futex (a barrier) woke
all worker threads and tried pulling the wakees to the waker nodes. In that
specific case, it could be handled by tuning MPI or openMP appropriately,
but the behavior is not illogical and was worth attempting to fix. However,
the approach was wrong. Given that we're at rc4 and a fix is not obvious,
it's better to play safe, revert this commit and retry later.

ocfs2: take inode cluster lock before moving reflinked inode from orphan dir
While reflinking an inode, we create a new inode in orphan directory,
then take EX lock on it, reflink the original inode to orphan inode and
release EX lock. Once the lock is released another node could request
it in EX mode from ocfs2_recover_orphans() which causes downconvert of
the lock, on this node, to NL mode.
Later we attempt to initialize security acl for the orphan inode and
move it to the reflink destination. However, while doing this we dont
take EX lock on the inode. This could potentially cause problems
because we could be starting transaction, accessing journal and
modifying metadata of the inode while holding NL lock and with another
node holding EX lock on the inode.
Fix this by taking orphan inode cluster lock in EX mode before
initializing security and moving orphan inode to reflink destination.
Use the __tracker variant while taking inode lock to avoid recursive
locking in the ocfs2_init_security_and_acl() call chain.

mm, oom: fix concurrent munlock and oom reaper unmap, v3
Since exit_mmap() is done without the protection of mm->mmap_sem, it is
possible for the oom reaper to concurrently operate on an mm until
MMF_OOM_SKIP is set.
This allows munlock_vma_pages_all() to concurrently run while the oom
reaper is operating on a vma. Since munlock_vma_pages_range() depends
on clearing VM_LOCKED from vm_flags before actually doing the munlock to
determine if any other vmas are locking the same memory, the check for
VM_LOCKED in the oom reaper is racy.
This is especially noticeable on architectures such as powerpc where
clearing a huge pmd requires serialize_against_pte_lookup(). If the pmd
is zapped by the oom reaper during follow_page_mask() after the check
for pmd_none() is bypassed, this ends up deferencing a NULL ptl or a
kernel oops.
Fix this by manually freeing all possible memory from the mm before
doing the munlock and then setting MMF_OOM_SKIP. The oom reaper can not
run on the mm anymore so the munlock is safe to do in exit_mmap(). It
also matches the logic that the oom reaper currently uses for
determining when to set MMF_OOM_SKIP itself, so there's no new risk of
excessive oom killing.
This issue fixes CVE-2018-
1000200.

init: fix false positives in W+X checking
load_module() creates W+X mappings via __vmalloc_node_range() (from
layout_and_allocate()->move_module()->module_alloc()) by using
PAGE_KERNEL_EXEC. These mappings are later cleaned up via
"call_rcu_sched(&freeinit->rcu, do_free_init)" from do_init_module().
This is a problem because call_rcu_sched() queues work, which can be run
after debug_checkwx() is run, resulting in a race condition. If hit,
the race results in a nasty splat about insecure W+X mappings, which
results in a poor user experience as these are not the mappings that
debug_checkwx() is intended to catch.
This issue is observed on multiple arm64 platforms, and has been
artificially triggered on an x86 platform.
Address the race by flushing the queued work before running the
arch-defined mark_rodata_ro() which then calls debug_checkwx().

Benerjee saved us!
15) Uh oh, we were leaking in udp_sendmsg and ping_v4_sendmsg. The ship
is now water tight, thanks to Andrey Ignatov.

net sched actions: fix refcnt leak in skbmod
When application fails to pass flags in netlink TLV when replacing
existing skbmod action, the kernel will leak refcnt:
$ tc actions get action skbmod index 1
total acts 0
action order 0: skbmod pipe set smac 00:11:22:33:44:55
index 1 ref 1 bind 0
For example, at this point a buggy application replaces the action with
index 1 with new smac 00:aa:22:33:44:55, it fails because of zero flags,
however refcnt gets bumped:
$ tc actions get actions skbmod index 1
total acts 0
action order 0: skbmod pipe set smac 00:11:22:33:44:55
index 1 ref 2 bind 0
$
Tha patch fixes this by calling tcf_idr_release() on existing actions.

rxrpc: Fixes
Here are three fixes for AF_RXRPC and two tracepoints that were useful for
finding them:
(1) Fix missing start of expect-Rx-by timeout on initial packet
transmission so that calls will time out if the peer doesn't respond.
(2) Fix error reception on AF_INET6 sockets by using the correct family of
sockopts on the UDP transport socket.
(3) Fix setting the minimum security level on kernel calls so that they
can be encrypted.
(4) Add a tracepoint to log ICMP/ICMP6 and other error reports from the
transport socket.
(5) Add a tracepoint to log UDP sendmsg failure so that we can find out if
transmission failure occurred on the UDP socket.
