rounddown_pow_of_two() is undefined when the input is 0. Therefore we need
to avoid it in ib_umem_find_best_pgsz and return 0. Otherwise, it could
result in not rejecting an invalid page size which eventually causes a
kernel oops due to the logical inconsistency.

The initial change breaking the logic is
commit 3d1f08b032dc ("mtd: spinand: Use the external ECC engine logic")
It inadvertently dropped proper OOB support while doing something
else.
Shortly later, half of it got re-integrated by
commit 868cbe2a6dce ("mtd: spinand: Fix OOB read")
(pointing by the way to a more early change which had nothing to do
with the issue). Problem is, this commit failed to revert the faulty
change entirely and missed the logic handling MTD_OPS_AUTO_OOB
requests.
Let's fix this mess by re-inserting the missing part now.

I have been fooled by the logic picking the right ECC engine which is

IO completion can be queued to a different CPU by the block subsystem as a "call
single function/data". The CPU may run these routines from the idle task, but it
does so with interrupts disabled.
It is not a good idea to do decryption with irqs disabled even in an idle task
context, so just defer it to a tasklet (as is done with requests from hard irqs).

Commit c318840fb2a4 ("USB: Gadget: dummy-hcd: Fix shift-out-of-bounds
bug") messed up the way dummy-hcd handles requests to turn on the
RESET port feature (I didn't notice that the original switch case
ended with a fallthrough). The call to set_link_state() was
inadvertently removed, as was the code to set the USB_PORT_STAT_RESET
flag when the speed is USB2.
In addition, the original code never checked whether the port was
connected before handling the port-reset request. There was a check
for the port being powered, but it was removed by that commit! In
practice this doesn't matter much because the kernel doesn't try to
reset disconnected ports, but it's still bad form.
This patch fixes these problems by changing the fallthrough to break,
adding back in the missing set_link_state() call, setting the
port-reset status flag, adding a port-is-connected test, and removing
a redundant assignment statement.

KASAN reported a slab-out-of-bounds read of size 1 in
kdf_create_vcrat_image_cpu().
This occurs when, for example, when on an x86_64 with a single NUMA node
because kfd_fill_iolink_info_for_cpu() is a no-op, but afterwards the
sub_type_hdr->length, which is out-of-bounds, is read and multiplied by
entries. Fortunately, entries is 0 in this case so the overall
crat_table->length is still correct.
Check if there were any entries before de-referencing sub_type_hdr which
may be pointing to out-of-bounds memory.

commit a861736dae64 ("drm/amd/display: Fixed Intermittent blue screen on OLED panel")
causes power regression for many users. It seems that this change causes
the MCLK to get forced high; this creates a regression for many users
since their devices were not able to drop to a low state after this
change. For this reason, this reverts commit
a861736dae644a0d7abbca0c638ae6aad28feeb8.

[Why]
The initial purpose of dcn10 pipe split is to support some high
bandwidth mode which requires dispclk greater than max dispclk. By
initial bring up power measurement data, it showed power consumption is
less with pipe split for dcn block. This could be reason for enable pipe
split by default. By battery life measurement of some Chromebooks,
result shows battery life is longer with pipe split disabled.
[How]
Disable pipe split by default. Pipe split could be still enabled when
required dispclk is greater than max dispclk.

Currently, the function i40e_construct_skb_zc only frees the input xdp
buffer when the output skb is successfully built. On error, the
function i40e_clean_rx_irq_zc does not commit anything for the current
packet descriptor and simply exits the packet descriptor processing
loop, with the plan to restart the processing of this descriptor on
the next invocation. Therefore, on error the ring next-to-clean
pointer should not advance, the xdp i.e. *bi buffer should not be
freed and the current buffer info should not be invalidated by setting
*bi to NULL. Therefore, the *bi should only be set to NULL when the
function i40e_construct_skb_zc is successful, otherwise a NULL *bi
will be dereferenced when the work for the current descriptor is
eventually restarted.

Use of __napi_schedule_irqoff() is not safe with PREEMPT_RT in which
hard interrupts are not disabled while running the threaded interrupt.
Using __napi_schedule() works for both PREEMPT_RT and mainline Linux,
just at the cost of an additional check if interrupts are disabled for
mainline (since they are already disabled).

With INTX or GSI delivery, Xen uses the event channel structures of CPU0.
If the interrupt gets handled by Linux on a different CPU, then no events
are seen as pending. Rather than introducing locking to allow other CPUs
to process CPU0's events, just ensure that the PCI interrupts happens
only on CPU0.

For a while, event channel notification via the PCI platform device
has been broken, because we attempt to communicate with xenstore before
we even have notifications working, with the xs_reset_watches() call
in xs_init().
We tend to get away with this on Xen versions below 4.0 because we avoid
calling xs_reset_watches() anyway, because xenstore might not cope with
reading a non-existent key. And newer Xen *does* have the vector
callback support, so we rarely fall back to INTX/GSI delivery.
To fix it, clean up a bit of the mess of xs_init() and xenbus_probe()
startup. Call xs_init() directly from xenbus_init() only in the !XS_HVM
case, deferring it to be called from xenbus_probe() in the XS_HVM case
instead.
Then fix up the invocation of xenbus_probe() to happen either from its
device_initcall if the callback is available early enough, or when the
callback is finally set up. This means that the hack of calling
xenbus_probe() from a workqueue after the first interrupt, or directly
from the PCI platform device setup, is no longer needed.

This reverts commit 367c820ef08082e68df8a3bc12e62393af21e4b5.
lockup_detector_init() makes heavy use of per-cpu variables and must be
called with preemption disabled. Usually, it's handled early during boot
in kernel_init_freeable(), before SMP has been initialised.
Since we do not know whether or not our PMU interrupt can be signalled
as an NMI until considerably later in the boot process, the Arm PMU
driver attempts to re-initialise the lockup detector off the back of a
device_initcall(). Unfortunately, this is called from preemptible
context and results in the following splat:
| BUG: using smp_processor_id() in preemptible [00000000] code: swapper/0/1

Rather than bodge this with raw_smp_processor_id() or randomly disabling

do this properly.

Allow issuing an IOCTL_PRIVCMD_MMAP_RESOURCE ioctl with num = 0 and
addr = 0 in order to fetch the size of a specific resource.
Add a shortcut to the default map resource path, since fetching the
size requires no address to be passed in, and thus no VMA to setup.
This is missing from the initial implementation, and causes issues
when mapping resources that don't have fixed or known sizes.

Commit e7b5d63a82fe ("mmc: sdhci-brcmstb: Add shutdown callback")
that added a shutdown callback to the diver, is causing "mmc timeout"
errors on S5 suspend. The problem was that the "remove" was queuing
additional MMC commands after the "shutdown" and these caused
timeouts as the MMC queues were cleaned up for "remove". The
shutdown callback will be changed to calling sdhci-pltfm_suspend
which should get better power savings because the clocks will be
shutdown.

The function bnxt_get_ulp_stat_ctxs() does not count the stats contexts
used by the RDMA driver correctly when the RDMA driver is freeing the
MSIX vectors. It assumes that if the RDMA driver is registered, the
additional stats contexts will be needed. This is not true when the
RDMA driver is about to unregister and frees the MSIX vectors.
This slight error leads to over accouting of the stats contexts needed
after the RDMA driver has unloaded. This will cause some firmware
warning and error messages in dmesg during subsequent config. changes
or ifdown/ifup.
Fix it by properly accouting for extra stats contexts only if the
RDMA driver is registered and MSIX vectors have been successfully
requested.

This commit enables the use of the r8153_ecm driver, introduced with
commit c1aedf015ebdd0 ("net/usb/r8153_ecm: support ECM mode for
RTL8153") for the Lenovo Powered USB-C Hub (17ef:721e) based on the
Realtek RTL8153B chip.
This results in the following driver preference:
- if r8152 is available, use the r8152 driver
- if r8152 is not available, use the r8153_ecm driver
This is done to prevent the NIC from constantly sending pause frames
when the host system enters standby (fixed by using the r8152 driver
in "r8152: Add Lenovo Powered USB-C Travel Hub"), while still allowing
the device to work with the r8153_ecm driver as a fallback.

This USB-C Hub (17ef:721e) based on the Realtek RTL8153B chip used to
use the cdc_ether driver. However, using this driver, with the system
suspended the device constantly sends pause-frames as soon as the
receive buffer fills up. This causes issues with other devices, where
some Ethernet switches stop forwarding packets altogether.
Using the Realtek driver (r8152) fixes this issue. Pause frames are no
longer sent while the host system is suspended.

Sometimes, when dm-crypt executes decryption in a tasklet, we may get
"BUG: KASAN: use-after-free in tasklet_action_common.constprop..."
with a kasan-enabled kernel.
When the decryption fully completes in the tasklet, dm-crypt will call
bio_endio(), which in turn will call clone_endio() from dm.c core code. That
function frees the resources associated with the bio, including per bio private
structures. For dm-crypt it will free the current struct dm_crypt_io, which
contains our tasklet object, causing use-after-free, when the tasklet is being
dequeued by the kernel.
To avoid this, do not call bio_endio() from the current tasklet context, but
delay its execution to the dm-crypt IO workqueue.
