The SWR2 Soundwire instance has 1 output and 4 input ports, so for the
headset recording (via the WCD9385 codec and the TX macro codec) we want
to use the next DAI, not the first one (see qcom,dout-ports and
qcom,din-ports for soundwire@6d30000 node).
Original code was copied from other devices like SM8450 and SM8550. On
the SM8450 this was a correct setting, however on the SM8550 this worked
probably only by coincidence, because the DTS defined no output ports on
SWR2 Soundwire.
This is a necessary fix for proper audio recording via analogue
microphones connected to WCD9385 codec (e.g. headset AMIC2).

Pull parisc fix from Helge Deller:
"On parisc we have suffered since years from random segfaults which
seem to have been triggered due to cache inconsistencies. Those
segfaults happened more often on machines with PA8800 and PA8900 CPUs,
which have much bigger caches than the earlier machines.
Dave Anglin has worked over the last few weeks to fix this bug. His
patch has been successfully tested by various people on various
machines and with various kernels (6.6, 6.8 and 6.9), and the debian
buildd servers haven't shown a single random segfault with this patch.
Since the cache handling has been reworked, the patch is slightly
bigger than I would like in this stage, but the greatly improved
stability IMHO justifies the inclusion now"

Al reported a possible use-after-free (UAF) in kvm_spapr_tce_attach_iommu_group().
It looks up `stt` from tablefd, but then continues to use it after doing
fdput() on the returned fd. After the fdput() the tablefd is free to be
closed by another thread. The close calls kvm_spapr_tce_release() and
then release_spapr_tce_table() (via call_rcu()) which frees `stt`.
Although there are calls to rcu_read_lock() in
kvm_spapr_tce_attach_iommu_group() they are not sufficient to prevent
the UAF, because `stt` is used outside the locked regions.
With an artifcial delay after the fdput() and a userspace program which
triggers the race, KASAN detects the UAF:

Fix it by delaying the fdput() until `stt` is no longer in use, which
is effectively the entire function. To keep the patch minimal add a call
to fdput() at each of the existing return paths. Future work can convert
the function to goto or __cleanup style cleanup.
With the fix in place the test case no longer triggers the UAF.

An ASLR regression was noticed [1] and tracked down to file-mapped areas
being backed by THP in recent kernels. The 21-bit alignment constraint
for such mappings reduces the entropy for randomizing the placement of
64-bit library mappings and breaks ASLR completely for 32-bit libraries.
The reported issue is easily addressed by increasing vm.mmap_rnd_bits and
vm.mmap_rnd_compat_bits. This patch just provides a simple way to set
ARCH_MMAP_RND_BITS and ARCH_MMAP_RND_COMPAT_BITS to their maximum values
allowed by the architecture at build time.

The only key that should wake up the phone is power button press. This
prevents accidental wakeup due to e.g. pressing the buttons in the
pocket or backpack and is in line what userspace uses to unblank the
device.

The memory object in this case is for efi_rt_stack_top and is allocated
in an initcall. So this is certainly a false positive. Mark the object
as not a leak to quash it.

The logic in __efi_memmap_init() is shared between two different
execution flows:
- mapping the EFI memory map early or late into the kernel VA space, so
that its entries can be accessed;
- the x86 specific cloning of the EFI memory map in order to insert new
entries that are created as a result of making a memory reservation
via a call to efi_mem_reserve().
In the former case, the underlying memory containing the kernel's view
of the EFI memory map (which may be heavily modified by the kernel
itself on x86) is not modified at all, and the only thing that changes
is the virtual mapping of this memory, which is different between early
and late boot.
In the latter case, an entirely new allocation is created that carries a
new, updated version of the kernel's view of the EFI memory map. When
installing this new version, the old version will no longer be
referenced, and if the memory was allocated by the kernel, it will leak
unless it gets freed.
The logic that implements this freeing currently lives on the code path
that is shared between these two use cases, but it should only apply to
the latter. So move it to the correct spot.
While at it, drop the dummy definition for non-x86 architectures, as
that is no longer needed.

EFI runtime services are remapped into the lower 1 GiB of virtual
address space at boot, so they are guaranteed to be able to co-exist
with the kernel virtual mappings without the need to allocate space for
them in the kernel's vmalloc region, which is rather small.
This means those mappings are covered by TTBR0 when LPAE PAN is enabled,
and so 'user' access must be enabled while such calls are in progress.
