arm64: defconfig: Enable CONFIG_WQ_POWER_EFFICIENT_DEFAULT
commit
cee22a15052f ("workqueues: Introduce new flag WQ_POWER_EFFICIENT
for power oriented workqueues") introduced the concept of power
efficient workqueues (4 years back), but it was never enabled in
upstream kernel configs.
Power efficient workqueues are simply marked as "unbound," so that jobs
queued to them can run on any CPU in the system. It leaves the target
CPU selection to the scheduler, which is the best place for such
decision making. This improves power efficiency for workqueues which are
otherwise pinned to a CPU.
Enable it for ARM64 platforms as ARM platforms were the main target for
the introduction of power efficient workqueues.

ARM: OMAP2+: omap_device: drop broken RPM status update from suspend_noirq
Since commit
a8636c89648a ("PM / Runtime: Don't allow to suspend a
device with an active child"), which went into 4.10, it is no longer
permitted to set RPM_SUSPENDED state for a device with active children
(unless power.ignore_children is set).
This specifically means that the attempts to do just that from the omap
pm-domain suspend_noirq callback have since been failing whenever a
child is active, for example:
am335x-usb-childs
47400000.usb: runtime PM trying to suspend
device but active child
Silence this warning by dropping the broken pm_runtime_set_suspended()
call from the omap suspend_noirq callback along with the redundant
pm_runtime_set_active() in resume_noirq.
This effectively reverts commit
3522bf7bfa24 ("ARM: OMAP2+: omap_device:
maintain sane runtime pm status around suspend/resume"), which started
updating the RPM state after the runtime_suspend callback (!) for active
omap devices had been called during system suspend. The rationale was
that a later pm_runtime_get_sync() would then fail (even after runtime
pm had been disabled) and that this in turn would avoid any external
aborts when accessing registers with clocks disabled. (See also commit
6f3c77b040fc ("PM / Runtime: let rpm_resume() succeed if RPM_ACTIVE,
even when disabled, v2").
But during the suspend_noirq phase all children would already have been
suspended and their drivers would specifically not attempt any further
register accesses. And if this was all just a workaround for random
device drivers doing cross-tree calls during system suspend, those
drivers should be fixed and updated to explicitly model such
dependencies using device-links instead (and either way, any such calls
have been causing crashes since 4.10).

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.

platform/x86: intel-vbtn: match power button on press rather than release
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).

sparc64: Fix exception handling in UltraSPARC-III memcpy.
Mikael Pettersson reported that some test programs in the strace-4.18
testsuite cause an OOPS.
After some debugging it turns out that garbage values are returned
when an exception occurs, causing the fixup memset() to be run with
bogus arguments.
The problem is that two of the exception handler stubs write the
successfully copied length into the wrong register.
Fixes:

arm64: avoid overflow in VA_START and PAGE_OFFSET
The bitmask used to define these values produces overflow, as seen by
this compiler warning:
arch/arm64/kernel/head.S:47:8: warning:
integer overflow in preprocessor expression
#elif (PAGE_OFFSET & 0x1fffff) != 0
^~~~~~~~~~~
arch/arm64/include/asm/memory.h:52:46: note:
expanded from macro 'PAGE_OFFSET'
#define PAGE_OFFSET (UL(0xffffffffffffffff) << (VA_BITS -
1))
~~~~~~~~~~~~~~~~~~ ^
It would be preferrable to use GENMASK_ULL() instead, but it's not set
up to be used from assembly (the UL() macro token pastes UL suffixes
when not included in assembly sources).
