2f6edb6bcb ARM: dts: aspeed: Fix AST2600 quad spi group
Requesting quad mode for the FMC resulted in an error:

  &fmc {
         status = "okay";
 +       pinctrl-names = "default";
 +       pinctrl-0 = <&pinctrl_fwqspi_default>'

[    0.742963] aspeed-g6-pinctrl 1e6e2000.syscon:pinctrl: invalid function FWQSPID in map table


This is because the quad mode pins are a group of pins, not a function.

After applying this patch we can request the pins and the QSPI data
lines are muxed:

 # cat /sys/kernel/debug/pinctrl/1e6e2000.syscon\:pinctrl-aspeed-g6-pinctrl/pinmux-pins |grep 1e620000.spi
 pin 196 (AE12): device 1e620000.spi function FWSPID group FWQSPID

Qualcomm ARM64 DeviceTree fixes for 5.17

This starts off by fixing an issue introduced in a bug fix in the
global clock controller, where the symbol clocks for UFS would
end up picking the wrong parent clock which breaks UFS.

It then makes sure that the reference clock for the USB blocks are
enabled, even with booting without clk_ignore_unused.

It corrects the apps SMMU interrupts defintion by adding a missing
interrupt in the list.

Lastly it disables the Qualcomm crypto hardware (for now) on the Lenovo
Yoga C630, to prevent the cryptomanager tests during boot from crashing
the device.

c432cd598a soc: mediatek: mt8192-mmsys: Fix dither to dsi0 path's input sel
In commit d687e056a1 ("soc: mediatek: mmsys: Add mt8192 mmsys routing table"),
the mmsys routing table for mt8192 was introduced but the input selector
for DITHER->DSI0 has no value assigned to it.

This means that we are clearing bit 0 instead of setting it, blocking
communication between these two blocks; due to that, any display that
is connected to DSI0 will not work, as no data will go through.
The effect of that issue is that, during bootup, the DRM will block for
some time, while atomically waiting for a vblank that never happens;
later, the situation doesn't get better, leaving the display in a
non-functional state.

To fix this issue, fix the route entry in the table by assigning the
dither input selector to MT8192_DISP_DSI0_SEL_IN.

32568ae375 arm64: dts: mt8183: jacuzzi: Fix bus properties in anx's DSI endpoint
mt8183-kukui-jacuzzi has an anx7625 bridge connected to the output of
its DSI host. However, after commit fd0310b6fe ("drm/bridge: anx7625:
add MIPI DPI input feature"), a bus-type property started being required
in the endpoint node by the driver to indicate whether it is DSI or DPI.

Add the missing bus-type property and set it to 5
(V4L2_FWNODE_BUS_TYPE_PARALLEL) so that the driver has its input
configured to DSI and the display pipeline can probe correctly.

While at it, also set the data-lanes property that was also introduced
in that same commit, so that we don't rely on the default value.

Running the memfd script ./run_hugetlbfs_test.sh will often end in error

    fuse: DONE

If no hugetlb pages have been preallocated, run_hugetlbfs_test.sh will
allocate 'just enough' pages to run the test.  In the SEAL-FUTURE-WRITE
test the mfd_fail_write routine maps the file, but does not unmap.  As a
result, two hugetlb pages remain reserved for the mapping.  When the
fallocate call in the SEAL-SHRINK test attempts allocate all hugetlb
pages, it is short by the two reserved pages.

Fix by making sure to unmap in mfd_fail_write.

f798a1d4f9 mm: fix use-after-free bug when mm->mmap is reused after being freed
oom reaping (__oom_reap_task_mm) relies on a 2 way synchronization with
exit_mmap.  First it relies on the mmap_lock to exclude from unlock
path[1], page tables tear down (free_pgtables) and vma destruction.
This alone is not sufficient because mm->mmap is never reset.

For historical reasons[2] the lock is taken there is also MMF_OOM_SKIP
set for oom victims before.

The oom reaper only ever looks at oom victims so the whole scheme works
properly but process_mrelease can opearate on any task (with fatal
signals pending) which doesn't really imply oom victims.  That means
that the MMF_OOM_SKIP part of the synchronization doesn't work and it
can see a task after the whole address space has been demolished and
traverse an already released mm->mmap list.  This leads to use after
free as properly caught up by KASAN report.

Fix the issue by reseting mm->mmap so that MMF_OOM_SKIP synchronization
is not needed anymore.  The MMF_OOM_SKIP is not removed from exit_mmap
yet but it acts mostly as an optimization now.

e79ce98323 hugetlbfs: fix a truncation issue in hugepages parameter
When we specify a large number for node in hugepages parameter, it may
be parsed to another number due to truncation in this statement:

	node = tmp;

For example, add following parameter in command line:

	hugepagesz=1G hugepages=4294967297:5

and kernel will allocate 5 hugepages for node 1 instead of ignoring it.

I move the validation check earlier to fix this issue, and slightly
simplifies the condition here.

70effdc375 kasan: test: prevent cache merging in kmem_cache_double_destroy
With HW_TAGS KASAN and kasan.stacktrace=off, the cache created in the
kmem_cache_double_destroy() test might get merged with an existing one.
Thus, the first kmem_cache_destroy() call won't actually destroy it but
will only decrease the refcount.  This causes the test to fail.

Provide an empty constructor for the created cache to prevent the cache
from getting merged.

the kernel can't use huge_pte_offset before it set the pte entry because
a page table lookup check for huge PTE bit in the page table to
differentiate between a huge pte entry and a pointer to pte page.  A
huge_pte_alloc won't mark the page table entry huge and hence kernel
should not use huge_pte_offset after a huge_pte_alloc.

Currently, --entries uses -e as the short version in the hist mode of
timerlat and osnoise tools. But as -e is already used to enable events
on trace sessions by other tools, thus let's keep it available for the
same usage for all rtla tools.

Make -E the short version of --entries for hist mode on all tools.

Note: rtla was merged in this merge window, so rtla was not released yet.

Al Viro brought it to my attention that the dentries may not be filled
when the parse_options() is called, causing the call to set_gid() to
possibly crash. It should only be called if parse_options() succeeds
totally anyway.

He suggested the logical place to do the update is in apply_options().

22e9f71072 RDMA/cma: Do not change route.addr.src_addr outside state checks
If the state is not idle then resolve_prepare_src() should immediately
fail and no change to global state should happen. However, it
unconditionally overwrites the src_addr trying to build a temporary any
address.

For instance if the state is already RDMA_CM_LISTEN then this will corrupt
the src_addr and would cause the test in cma_cancel_operation():

           if (cma_any_addr(cma_src_addr(id_priv)) && !id_priv->cma_dev)

Which would manifest as this trace from syzkaller:

  BUG: KASAN: use-after-free in __list_add_valid+0x93/0xa0 lib/list_debug.c:26

This is indicating that an rdma_id_private was destroyed without doing
cma_cancel_listens().

Instead of trying to re-use the src_addr memory to indirectly create an
any address derived from the dst build one explicitly on the stack and
bind to that as any other normal flow would do. rdma_bind_addr() will copy
it over the src_addr once it knows the state is valid.

This is similar to commit bc0bdc5afa ("RDMA/cma: Do not change
route.addr.src_addr.ss_family")
