This behavior is triggered by the "default y" in the definition of
RPCSEC_GSS.
The "default y" was added in 2010 by commit df486a2590 ("NFS: Fix
the selection of security flavours in Kconfig"). However,
svc_gss_principal was removed in 2012 by commit 03a4e1f6dd
("nfsd4: move principal name into svc_cred"), so the 2010 fix is
no longer necessary. We can safely change the NFS_V4 and NFSD_V4
dependencies back to RPCSEC_GSS_KRB5 to get the nicer v6.2
behavior back.
Selecting KRB5 symbolically represents the true requirement here:
that all spec-compliant NFSv4 implementations must have Kerberos
available to use.

The recent fix for the deferred I/O by the commit
3efc61d952 ("fbdev: Fix invalid page access after closing deferred I/O devices")
caused a regression when the same fb device is opened/closed while
it's being used. It resulted in a frozen screen even if something
is redrawn there after the close. The breakage is because the patch
was made under a wrong assumption of a single open; in the current
code, fb_deferred_io_release() cleans up the page mapping of the
pageref list and it calls cancel_delayed_work_sync() unconditionally,
where both are no correct behavior for multiple opens.
This patch adds a refcount for the opens of the device, and applies
the cleanup only when all files get closed.
As both fb_deferred_io_open() and _close() are called always in the
fb_info lock (mutex), it's safe to use the normal int for the
refcounting.
Also, a useless BUG_ON() is dropped.

The PE/COFF header has a NX compat flag which informs the firmware that
the application does not rely on memory regions being mapped with both
executable and writable permissions at the same time.
This is typically used by the firmware to decide whether it can set the
NX attribute on all allocations it returns, but going forward, it may be
used to enforce a policy that only permits applications with the NX flag
set to be loaded to begin wiht in some configurations, e.g., when Secure
Boot is in effect.
Even though the arm64 version of the EFI stub may relocate the kernel
before executing it, it always did so after disabling the MMU, and so we

Instead of ignoring errors returned by devm_clk_get() and manually
enabling the clk for the whole lifetime of the bound device, use
devm_clk_get_optional_enabled(). This is simpler and also more correct
as it doesn't ignore errors. This is also more correct because now the
call to clk_disable_unprepare() can be dropped from xgene_rng_remove()
which happened while the hwrn device was still registered. With the devm
callback disabling the clk happens correctly only after
devm_hwrng_register() is undone.
As a result struct xgene_rng_dev::clk is only used in xgene_rng_probe, and
so the struct member can be replaced by a local variable.

To fully utilize the BT polling/refresh rate, a few input events
are sent together to reduce event delay. This causes issue to the
timestamp generated by input_sync since all the events in the same
packet would pretty much have the same timestamp. This patch inserts
time interval to the events by averaging the total time used for
sending the packet.
This decision was mainly based on observing the actual time interval
between each BT polling. The interval doesn't seem to be constant,
due to the network and system environment. So, using solutions other
than averaging doesn't end up with valid timestamps.

pci_enable_pcie_error_reporting() enables the device to send ERR_*
Messages. Since f26e58bf6f ("PCI/AER: Enable error reporting when AER is

We currently have an issue with some BPPs when using DSC.
According to the HW team, the reason is that a single VDSC engine
instance has some BW limitations that must be accounted for.
So, whenever we approach around 90% of the CDCLK, a second VDSC engine
has to be used.
This always means using two slices. However, in our current code,
the amount of slices is calculated independently of whether
we need to enable the second VDSC engine or not.
This leads to some logical issues when, according to the pixel clock needs,
we need to enable the second VDSC engine.
But as we calculated previously that we can only use a single slice,
we can't do that and fail.
So, we need to fix that so that the number of VDSC engines enabled
should depend on the number of slices, and the number of slices
should also depend on BW requirements.
Lastly, we didn't have BPP limitation for ADLP/MTL/DG2 implemented,
which says that DSC output BPPs can only be chosen within the range of 8 to 27
(BSpec 49259).
All of this applied together allows us to fix existing FIFO underruns,
which we have in many DSC tests.

device yet, then call sync_state() for the device independent of the
state of its consumers.
This is useful for supplier devices that have one or more consumers that
don't have a driver but the consumers are in a state that don't use the
resources supplied by the supplier device.
This gives finer grained control than using the
fw_devlink.sync_state=timeout kernel commandline parameter.

When all devices that could probe have finished probing (based on
deferred_probe_timeout configuration or late_initcall() when
!CONFIG_MODULES), this parameter controls what to do with devices that
haven't yet received their sync_state() calls.
fw_devlink.sync_state=strict is the default and the driver core will
continue waiting on all consumers of a device to probe successfully
before sync_state() is called for the device. This is the default
behavior since calling sync_state() on a device when all its consumers
haven't probed could make some systems unusable/unstable. When this
option is selected, we also print the list of devices that haven't had
sync_state() called on them by the time all devices the could probe have
finished probing.
fw_devlink.sync_state=timeout will cause the driver core to give up
waiting on consumers and call sync_state() on any devices that haven't
yet received their sync_state() calls. This option is provided for
systems that won't become unusable/unstable as they might be able to
save power (depends on state of hardware before kernel starts) if all
devices get their sync_state().

The filename "wangxun" sorts between "intel" and "xscale", but
xscale/Kconfig contains "Intel XScale" prompts, so Wangxun ends up in the
wrong place in the config front-ends.
Move wangxun/Kconfig so the Wangxun devices appear in order in the user
interface.
