commit f7b32e7850 upstream.
Callers of mutex_unlock() have to make sure that the mutex stays alive
for the whole duration of the function call. For io_uring that means
that the following pattern is not valid unless we ensure that the
context outlives the mutex_unlock() call.
mutex_lock(&ctx->uring_lock);
req_put(req); // typically via io_req_task_submit()
mutex_unlock(&ctx->uring_lock);
Most contexts are fine: io-wq pins requests, syscalls hold the file,
task works are taking ctx references and so on. However, the task work
fallback path doesn't follow the rule.

notice readers the rethook is stopped (unregistered) or not, it should
be an __rcu pointer and use appropriate functions to be accessed. This
will use appropriate memory barrier when accessing it. OTOH,
rethook::data is never changed, so we don't need to check it in

NOTE: To avoid sparse warning, rethook::handler is defined by a raw

[ Upstream commit dccf78d39f ]
Ignat Korchagin complained that a potential config regression was
introduced by commit 89cde45591 ("kexec: consolidate kexec and crash
options into kernel/Kconfig.kexec"). Before the commit, CONFIG_CRASH_DUMP
has no dependency on CONFIG_KEXEC. After the commit, CRASH_DUMP selects
KEXEC. That enforces system to have CONFIG_KEXEC=y as long as
CONFIG_CRASH_DUMP=Y which people may not want.
In Ignat's case, he sets CONFIG_CRASH_DUMP=y, CONFIG_KEXEC_FILE=y and
CONFIG_KEXEC=n because kexec_load interface could have security issue if
kernel/initrd has no chance to be signed and verified.
CRASH_DUMP has select of KEXEC because Eric, author of above commit, met a
LKP report of build failure when posting patch of earlier version. Please
see below link to get detail of the LKP report:
https://lore.kernel.org/all/3e8eecd1-a277-2cfb-690e-5de2eb7b988e@oracle.com/T/#u
In fact, that LKP report is triggered because arm's <asm/kexec.h> is
wrapped in CONFIG_KEXEC ifdeffery scope. That is wrong. CONFIG_KEXEC
controls the enabling/disabling of kexec_load interface, but not kexec
feature. Removing the wrongly added CONFIG_KEXEC ifdeffery scope in
<asm/kexec.h> of arm allows us to drop the select KEXEC for CRASH_DUMP.
Meanwhile, change arch/arm/kernel/Makefile to let machine_kexec.o
relocate_kernel.o depend on KEXEC_CORE.

This is because we called riscv_noncoherent_supported() for all the stages
during IOCP probe. riscv_noncoherent_supported() function sets
noncoherent_supported variable to true which has an annotation set to
"__ro_after_init" due to which we were seeing the above splat. Fix this by
probing for IOCP only once in boot stage by having a boolean variable
"done" which will be set to true upon IOCP probe in errata_probe_iocp()
and we bail out early if "done" is set to true.
While at it make return type of errata_probe_iocp() to void as we were
not checking the return value in andes_errata_patch_func().

[ Upstream commit 37f3d61087 ]
JEDEC standard JESD84-B51 defines the eMMC Data Strobe line, which is
currently used only in HS400 mode, as a device->host clock signal that
"is used only in read operation. The Data Strobe is always High-Z (not
driven by the device and pulled down by RDS) or Driven Low in write
operation, except during CRC status response." RDS is a pull-down
resistor specified in the 10K-100K ohm range. Thus per the standard, the
Data Strobe is always pulled to ground (by the eMMC and/or RDS) during
write operations.
Evidently, the eMMC host controller in the RK3588 considers an active
voltage on the eMMC-DS line during a write to be an error.
The default (i.e. hardware reset, and Rockchip BSP) behavior for the
RK3588 is to activate the eMMC-DS pin's builtin pull-down. As a result,
many RK3588 board designers do not bother adding a dedicated RDS
resistor, instead relying on the RK3588's internal bias. The current
devicetree, however, disables this bias (`pcfg_pull_none`), breaking
HS400-mode writes for boards without a dedicated RDS, but with an eMMC
chip that chooses to High-Z (instead of drive-low) the eMMC-DS line.
(The Turing RK1 is one such board.)
Fix this by changing the bias in the (common) emmc_data_strobe case to
reflect the expected hardware/BSP behavior. This is unlikely to cause
regressions elsewhere: the pull-down is only relevant for High-Z eMMCs,
and if this is redundant with a (dedicated) RDS resistor, the effective
result is only a lower resistance to ground -- where the range of
tolerance is quite high. If it does, it's better fixed in the specific
devicetrees.

Function trace_buffered_event_disable() produces an unexpected warning
when the previous call to trace_buffered_event_enable() fails to
allocate pages for buffered events.
The situation can occur as follows:
* The counter trace_buffered_event_ref is at 0.
* The soft mode gets enabled for some event and
trace_buffered_event_enable() is called. The function increments
trace_buffered_event_ref to 1 and starts allocating event pages.
* The allocation fails for some page and trace_buffered_event_disable()
is called for cleanup.
* Function trace_buffered_event_disable() decrements
trace_buffered_event_ref back to 0, recognizes that it was the last
use of buffered events and frees all allocated pages.
* The control goes back to trace_buffered_event_enable() which returns.
The caller of trace_buffered_event_enable() has no information that
the function actually failed.
* Some time later, the soft mode is disabled for the same event.
Function trace_buffered_event_disable() is called. It warns on
"WARN_ON_ONCE(!trace_buffered_event_ref)" and returns.
Buffered events are just an optimization and can handle failures. Make
trace_buffered_event_enable() exit on the first failure and left any
cleanup later to when trace_buffered_event_disable() is called.

Since commit c7e73b5051 ("ARM: imx: mach-imx6ul: remove 14x14 EVK
specific PHY fixup")thet Ethernet PHY is no longer configured via code
in board file.
This caused Ethernet to stop working.
Fix this problem by describing the clocks and clock-names to the
Ethernet PHY node so that the KSZ8081 chip can be clocked correctly.

[ Upstream commit 209043cf09 ]
The i.MX8MP and i.MX8MQ devices both use the same DWC3 controller and
are both affected by a known issue with the controller due to specific
behaviour when park mode is enabled in SuperSpeed host mode operation.
Under heavy USB traffic from multiple endpoints the controller will
sometimes incorrectly process transactions such that some transactions
are lost, or the controller may hang when processing transactions. When
the controller hangs it does not recover.
This issue is documented partially within the linux-imx vendor kernel
which references a Synopsys STAR number 9001415732 in commits [1] and
additional details in [2]. Those commits provide some additional
controller internal implementation specifics around the incorrect
behaviour of the SuperSpeed host controller operation when park mode is
enabled.
The summary of this issue is that the host controller can incorrectly
enter/exit park mode such that part of the controller is in a state
which behaves as if in park mode even though it is not. In this state
the controller incorrectly calculates the number of TRBs available which
results in incorrect access of the internal caches causing the overwrite
of pending requests in the cache which should have been processed but
are ignored. This can cause the controller to drop the requests or hang
waiting for the pending state of the dropped requests.
The workaround for this issue is to disable park mode for SuperSpeed
operation of the controller through the GUCTL1[17] bit. This is already
available as a quirk for the DWC3 controller and can be enabled via the
'snps,parkmode-disable-ss-quirk' device tree property.
It is possible to replicate this failure on an i.MX8MP EVK with a USB
Hub connecting 4 SuperSpeed USB flash drives. Performing continuous
small read operations (dd if=/dev/sd... of=/dev/null bs=16) on the block
devices will result in device errors initially and will eventually
result in the controller hanging.

The VA addresses are coming from rdma-core in this diagram can be
arbitrary, but for 64k pages, the VA may be offset by some number of HCA
4k pages and followed by some number of HCA 4k pages.
The current iterator doesn't account for either the preceding 4k pages or
the following 4k pages.
Fix the issue by extending the ib_block_iter to contain the number of DMA
pages like comment [1] says and by using __sg_advance to start the
iterator at the first live HCA page.
The changes are contained in a parallel set of iterator start and next
functions that are umem aware and specific to umem since there is one user
of the rdma_for_each_block() without umem.
These two fixes prevents the extra pages before and after the user MR
data.
Fix the preceding pages by using the __sq_advance field to start at the
first 4k page containing MR data.
Fix the following pages by saving the number of pgsz blocks in the
iterator state and downcounting on each next.
This fix allows for the elimination of the small page crutch noted in the
Fixes.

The multiplier is already promoted to unsigned long, however the
frequency calculations done when using level indexing mode doesn't

value of 1000 at all the usage sites.
Clean that up by assigning the multiplier value of 1000 when using
the perf level indexing mode and update the frequency calculations to
use the multiplier instead. It should fix the possible frequency
truncation for all the values greater than or equal to 4GHz on 64-bit
machines.
