Pull LSM support for IORING_OP_URING_CMD from Paul Moore:
"Add SELinux and Smack controls to the io_uring IORING_OP_URING_CMD.
These are necessary as without them the IORING_OP_URING_CMD remains
outside the purview of the LSMs (Luis' LSM patch, Casey's Smack patch,
and my SELinux patch). They have been discussed at length with the
io_uring folks, and Jens has given his thumbs-up on the relevant
patches (see the commit descriptions).
There is one patch that is not strictly necessary, but it makes
testing much easier and is very trivial: the /dev/null
IORING_OP_URING_CMD patch."

By using 16-bit I/O on the GPIO peripheral, which is apparently not safe
on MIPS, the IMR can end up containing garbage. This then results in
interrupt triggers for lines that don't have an interrupt handler
associated. The irq_desc lookup fails, and the ISR will not be cleared,
keeping the CPU busy until reboot, or until another IMR operation
restores the correct value. This situation appears to happen very
rarely, for < 0.5% of IMR writes.
Instead of using 8-bit or 16-bit I/O operations on the 32-bit memory
mapped peripheral registers, switch to using 32-bit I/O only, operating
on the entire bank for all single bit line settings. For 2-bit line
settings, with 16-bit port values, stick to manual (un)packing.
This issue has been seen on RTL8382M (HPE 1920-16G), RTL8391M (Netgear
GS728TP v2), and RTL8393M (D-Link DGS-1210-52 F3, Zyxel GS1900-48).

The cache_size field of copen is specified by the user daemon.
If cache_size < 0, then the OPEN request is expected to fail,

Fix this by returning error when cache_size is an invalid error code.

The function neigh_timer_handler() is a timer handler that runs in an
atomic context. When used by rocker, neigh_timer_handler() calls
"kzalloc(.., GFP_KERNEL)" that may sleep. As a result, the sleep in
atomic context bug will happen. One of the processes is shown below:
ofdpa_fib4_add()
...
neigh_add_timer()
(wait a timer)
neigh_timer_handler()
neigh_release()
neigh_destroy()
rocker_port_neigh_destroy()
rocker_world_port_neigh_destroy()
ofdpa_port_neigh_destroy()
ofdpa_port_ipv4_neigh()
kzalloc(sizeof(.., GFP_KERNEL) //may sleep
This patch changes the gfp_t parameter of kzalloc() from GFP_KERNEL to
GFP_ATOMIC in order to mitigate the bug.

Check if drm_sched_job_init is performed before job_free by checking
s_fence.
v2: Check hw_fence.ops instead since it could be NULL if fence is not
initialized. Reverse the condition since !=NULL check is discouraged in
kernel.

[Why]
When ODM is enabled, H timing control register reset
to 0. Div mode manual field get overwritten causing
no display on certain modes for dcn314.
[How]
Use REG_UPDATE instead of REG_SET to set div_mode
field.

[Why]
Each index in the DPSTREAMCLK_CNTL register
phyiscally maps 1-to-1 with HPO stream encoder
instance. On the other hand, each index in
DTBCLK_P_CNTL physically maps 1-to-1 with OTG
instance.
Current DCN32 DPSTREAMCLK_CLK programing assumes
that OTG instance always maps 1-to-1 with
HPO stream encoder instance. This is not always
guaranteed and can result in blackscreen.
[How]
Program the correct dpstreamclk instance with
the correct dtbclk_p source.

The alignment check in prepare_hugepage_range() is wrong for 2 GB
hugepages, it only checks for 1 MB hugepage alignment.
This can result in kernel crash in __unmap_hugepage_range() at the
BUG_ON(start & ~huge_page_mask(h)) alignment check, for mappings
created with MAP_FIXED at unaligned address.
Fix this by correctly handling multiple hugepage sizes, similar to the
generic version of prepare_hugepage_range().

Add proper alignment for .nospec_call_table and .nospec_return_table in
vmlinux.
[hca@linux.ibm.com]: The problem with the missing alignment of the nospec
tables exist since a long time, however only since commit e6ed91fd07
("s390/alternatives: remove padding generation code") and with
CONFIG_RELOCATABLE=n the kernel may also crash at boot time.
The above named commit reduced the size of struct alt_instr by one byte,
so its new size is 11 bytes. Therefore depending on the number of cpu
alternatives the size of the __alt_instructions array maybe odd, which
again also causes that the addresses of the nospec tables will be odd.
If the address of __nospec_call_start is odd and the kernel is compiled
With CONFIG_RELOCATABLE=n the compiler may generate code that loads the
address of __nospec_call_start with a 'larl' instruction.
This will generate incorrect code since the 'larl' instruction only works
with even addresses. In result the members of the nospec tables will be
accessed with an off-by-one offset, which subsequently may lead to
addressing exceptions within __nospec_revert().

The failing address alignment to HPAGE_MASK in do_exception(), for
hugetlb faults, was useless from the beginning. With 2 GB hugepage
support it became wrong, but w/o further negative impact. Now it
could have negative performance impact because it breaks the cacheline
optimization for process_huge_page().
Therefore, remove it.
Note that we still have failing address alignment by HW to PAGE_SIZE,
for all page faults, not just hugetlb faults. So this patch will not
fix UFFD_FEATURE_EXACT_ADDRESS for userfaultfd handling. It will just
move the failing address for hugetlb faults a bit closer to the real
address, at 4K page granularity, similar to normal page faults.

- Since the commit 1227d2a20c ("bus: mhi: host: Move IRQ allocation to
controller registration phase"), the MHI context gets freed during
mhi_unregister_controller(). But when the MHI IRQs are shared, the IRQ
handler may get invoked during __free_irq() if CONFIG_DEBUG_SHIRQ is set.
In that case, there will be a null pointer dereference because of trying to
use the freed context struct.
So for fixing the issue, let's check for the existence of the context struct
at the start of the handler before handling the IRQ.
