Memory hot unplug on PowerNV radix hosts is broken. Our memory block
size is 256MB but since we map the linear region with very large
pages, each pte we tear down maps 1GB.
A hot unplug of one 256MB memory block results in 768MB of memory
getting unintentionally unmapped. At this point we are likely to oops.
Fix this by increasing our memory block size to 1GB on PowerNV radix
hosts.

There are three important fields that indicate the overall health and
status of an array: dev_health, sync_ratio, and sync_action. They tell
us the condition of the devices in the array, and the degree to which
the array is synchronized.
This commit fixes a condition that is reported incorrectly. When a member
of the array is being rebuilt or a new device is added, the "recover"
process is used to synchronize it with the rest of the array. When the
process is complete, but the sync thread hasn't yet been reaped, it is
possible for the state of MD to be:
mddev->recovery = [ MD_RECOVERY_RUNNING MD_RECOVERY_RECOVER MD_RECOVERY_DONE ]
curr_resync_completed = <max dev size> (but not MaxSector)
and all rdevs to be In_sync.
This causes the 'array_in_sync' output parameter that is passed to
rs_get_progress() to be computed incorrectly and reported as 'false' --
or not in-sync. This in turn causes the dev_health status characters to
be reported as all 'a', rather than the proper 'A'.
This can cause erroneous output for several seconds at a time when tools
will want to be checking the condition due to events that are raised at
the end of a sync process. Fix this by properly calculating the
'array_in_sync' return parameter in rs_get_progress().
Also, remove an unnecessary intermediate 'recovery_cp' variable in
rs_get_progress().

Commit 34b1744c91cc ("nfsd4: define ->op_release for compound ops")
defined a couple ->op_release functions and run them if necessary.
But there's a problem with that is that it reused
nfsd4_secinfo_release() as the op_release of OP_SECINFO_NO_NAME, and
caused a leak on struct nfsd4_secinfo_no_name in
nfsd4_encode_secinfo_no_name(), because there's no .si_exp field in
struct nfsd4_secinfo_no_name.
I found this because I was unable to umount an ext4 partition after
exporting it via NFS & run fsstress on the nfs mount. A simplified
reproducer would be:
# mount a local-fs device at /mnt/test, and export it via NFS with
# fsid=0 export option (this is required)
mount /dev/sda5 /mnt/test
echo "/mnt/test *(rw,no_root_squash,fsid=0)" >> /etc/exports
service nfs restart
# locally mount the nfs export with all default, note that I have
# nfsv4.1 configured as the default nfs version, because of the
# fsid export option, v4 mount would fail and fall back to v3
mount localhost:/mnt/test /mnt/nfs
# try to umount the underlying device, but got EBUSY
umount /mnt/nfs
service nfs stop
umount /mnt/test <=== EBUSY here
Fixed it by defining a separate nfsd4_secinfo_no_name_release()
function as the op_release method of OP_SECINFO_NO_NAME that
releases the correct nfsd4_secinfo_no_name structure.

Enforcing exclusive ownership on upper/work dirs caused a docker
regression: https://github.com/moby/moby/issues/34672.
Euan spotted the regression and pointed to the offending commit.
Vivek has brought the regression to my attention and provided this
reproducer:
Terminal 1:
mount -t overlay -o workdir=work,lowerdir=lower,upperdir=upper none
merged/
Terminal 2:
unshare -m
Terminal 1:
umount merged
mount -t overlay -o workdir=work,lowerdir=lower,upperdir=upper none
merged/
mount: /root/overlay-testing/merged: none already mounted or mount point
busy
To fix the regression, I replaced the error with an alarming warning.
With index feature enabled, mount does fail, but logs a suggestion to
override exclusive dir protection by disabling index.
Note that index=off mount does take the inuse locks, so a concurrent
index=off will issue the warning and a concurrent index=on mount will fail.
Documentation was updated to reflect this change.

One of the recent changes introduced a warning about
undefined behavior in the sanity checking:
drivers/gpu/drm/i915/intel_ddi.c: In function 'intel_ddi_hdmi_level':
drivers/gpu/drm/i915/intel_ddi.c:654:6: error: 'n_hdmi_entries' may be used uninitialized in this function [-Werror=maybe-uninitialized]
It seems that the new cnl specific get_buf_trans functions
can return uninitialized data if the voltage level is set
to an unexpected value. This changes the code to always return
'1' in that error case, which seems like the safest choice
as we use one less than the number as an array index later on.

complains:
arch/x86/kvm/emulate.o: warning: objtool: .GCC.command.line+0x0: special: can't find new instruction
And also the kernel fails to link.
The problem is that the 'kvm_fastop_exception' code gets placed into the
throwaway '.GCC.command.line' section instead of '.text'.
Exception fixup code is conventionally placed in the '.fixup' section,
so put it there where it belongs.

parse_cec_param() compares a string with "cec_disable" using only 7
characters of the 11-character-long string.
The proper solution for this would be:
#define CEC_DISABLE "cec_disable"
strncmp(str, CEC_DISABLE, strlen(CEC_DISABLE))
but when comparing a string against a string constant strncmp() has no
advantage over strcmp() because the comparison is guaranteed to be bound by
the string constant. So just replace str strncmp() with strcmp().

For the fake device we have our own set of mock contexts that need to
match the real contexts we normally create. Currently this requires us
to manually instantiate them for the selftests, which I forgot.

This forces the HW to be in sync with the empty state. This should
help with the problem when LCDC is already enabled (e.g. by the
bootloader) at the initialization phase and the enable fails when a
new mode is applied.

For this specific PCI device, the eDP panel requires a higher panel
power cycle delay of 1300ms where the minimum spec requirement of panel
power cycle delay is 500ms. This fix in combination with correct
timestamp at which we get the panel power off time fixes the dP AUX CH
timeouts seen on various IGT tests.

Kernel stores the time in jiffies at which the eDP panel is turned
off. This should be obtained after the panel is off (after the
wait_panel_off). When we next attempt to turn the panel on, we use the
difference between the timestamp at which we want to turn the panel on
and timestamp at which panel was turned off to ensure that this is equal
to panel power cycle delay and if not we wait for the remaining
time. Not waiting for the panel power cycle delay can cause the panel to
not turn on giving rise to AUX timeouts for the attempted AUX
transactions.

If the vlan is down, free the packet instead of proceeding with other
processing, or counting it as received. If vlan interfaces are used
as slaves for bonding, with arp monitoring for connectivity, if the rx
counter is seen to be incrementing, then the bond device will not
observe that the interface is down.

Pull ARM SoC fixes from Olof Johansson:
"Our first batch of fixes this release cycle, unfortunately a bit
noisier than usual. Two major groups stand out:
- Some pinctril dts/dtsi changes for stm32 due to a new driver being
merged during the merge window, and this aligns the DT contents
between the old format and the new. This could arguably be moved to
the next merge window but it also seemed relatively harmless to
include now.
- Amlogic/meson had driver changes merged that required devicetree
changes to avoid functional/performance regressions. I've already
asked them to be more careful about this going forward, and making
sure drivers are compatible with older DTs when they make these
kind of changes. The platform is actively being upstreamed so
there's a few things in flight, we've seen this happen before and
sometimes it's hard to catch in time.
Besides that there is the usual mix of minor fixes"
