On a system which support SME but not SVE we can now disable streaming mode
via ptrace by writing FPSIMD formatted data through NT_ARM_SVE with a VL of
0. Extend fp-ptrace to cover rather than skip these cases, relax the check
for SVE writes of FPSIMD format data to not skip if SME is supported and
accept 0 as the VL when performing the ptrace write.

In order to allow exiting streaming mode on systems with SME but not SVE
we allow writes of FPSIMD format data via NT_ARM_SVE even when SVE is not
supported, add a test case that covers this to sve-ptrace.
We do not support reads.

Currently it is not possible to disable streaming mode via ptrace on SME
only systems, the interface for doing this is to write via NT_ARM_SVE but
such writes will be rejected on a system without SVE support. Enable this
functionality by allowing userspace to write SVE_PT_REGS_FPSIMD format data
via NT_ARM_SVE with the vector length set to 0 on SME only systems. Such
writes currently error since we require that a vector length is specified
which should minimise the risk that existing software is relying on current
behaviour.
Reads are not supported since I am not aware of any use case for this and
there is some risk that an existing userspace application may be confused if
it reads NT_ARM_SVE on a system without SVE. Existing kernels will return
FPSIMD formatted register state from NT_ARM_SVE if full SVE state is not
stored, for example if the task has not used SVE. Returning a vector length
of 0 would create a risk that software would try to do things like allocate
space for register state with zero sizes, while returning a vector length of
128 bits would look like SVE is supported. It seems safer to just not make
the changes to add read support.
It remains possible for userspace to detect a SME only system via the ptrace
interface only since reads of NT_ARM_SSVE and NT_ARM_ZA will succeed while
reads of NT_ARM_SVE will fail. Read/write access to the FPSIMD registers in
non-streaming mode is available via REGSET_FPR.
sve_set_common() already avoids allocating SVE storage when doing a FPSIMD
formatted write and allocating SME storage when doing a NT_ARM_SVE write so
we change the function to validate the new case and skip setting a vector
length for it.
The aim is to make a minimally invasive change, no operation that would
previously have succeeded will be affected, and we use a previously
defined interface in new circumstances rather than define completely new
ABI.

If there is a flood of faults then the MMU can become saturated while it
waits for the kernel to process the first fault and resume it, so that
the GMU becomes blocked. This is mainly a problem when the kernel reads
the state of the GPU for a devcoredump, because this takes a while. If
we timeout waiting for the GMU, check if this has happened and retry

The crashstate_get_bos() function allocates memory for `state->bos`
using kcalloc(), but the vmbind path does not check for allocation
failure before dereferencing it in the following drm_gpuvm_for_each_va()
loop. This could lead to a NULL pointer dereference if memory allocation
fails.
Fix this by wrapping the drm_gpuvm_for_each_va() loop with a NULL check
on state->bos, similar to the safety check in the non-vmbind path.

On BCM6358 (and also observed on BCM6368) the controller appears to
only generate as many SPI clocks as bytes that have been written into
the TX FIFO. For RX-only transfers the driver programs the transfer
length in SPI_MSG_CTL but does not write anything into the FIFO, so
chip select is deasserted early and the RX transfer segment is never
fully clocked in.
A concrete failing case is a three-transfer MAC address read from
SPI-NOR:
- TX 0x03 (read command)
- TX 3-byte address
- RX 6 bytes (MAC)
In contrast, a two-transfer JEDEC-ID read (0x9f + 6-byte RX) works
because the driver uses prepend_len and writes dummy bytes into the
TX FIFO for the RX part.
Fix this by writing 0xff dummy bytes into the TX FIFO for RX-only
segments so that the number of bytes written to the FIFO matches the
total message length seen by the controller.

The Devicetree Specification states:
The root of the interrupt tree is determined when traversal of the
interrupt tree reaches an interrupt controller node without an
interrupts property and thus no explicit interrupt parent.
However, of_irq_init() gratuitously assumes that a node without
interrupts has an actual interrupt parent if it finds an
interrupt-parent property higher up in the device tree. Hence when such
a property is present (e.g. in the root node), the root interrupt
controller may not be detected as such, causing a panic:
OF: of_irq_init: children remain, but no parents
Kernel panic - not syncing: No interrupt controller found.
Commit e91033621d ("of/irq: Use interrupts-extended to find
parent") already fixed a first part, by checking for the presence of an
interrupts-extended property. Fix the second part by only calling
of_irq_find_parent() when an interrupts property is present.

- Fix hostfs mounting when passing host root during boot
- Fix dynamic lookup to fail on cell lookup failure
- Fix missing file type when reading bfs inodes from disk
- Enforce checking of sb_min_blocksize() calls and update all callers
accordingly
- Restore write access before closing files opened by open_exec() in
binfmt_misc
- Always freeze efivarfs during suspend/hibernate cycles
- Fix statmount()'s and listmount()'s grab_requested_mnt_ns() helper to
actually allow mount namespace file descriptor in addition to mount
namespace ids
- Fix tmpfs remount when noswap is specified
- Switch Landlock to iput_not_last() to remove false-positives from
might_sleep() annotations in iput()
- Remove dead node_to_mnt_ns() code
- Ensure that per-queue kobjects are successfully created

xfs: check the return value of sb_min_blocksize() in xfs_fs_fill_super
isofs: check the return value of sb_min_blocksize() in isofs_fill_super
exfat: check return value of sb_min_blocksize in exfat_read_boot_sector
vfat: fix missing sb_min_blocksize() return value checks
mnt: Remove dead code which might prevent from building

afs: Fix dynamic lookup to fail on cell lookup failure
hostfs: Fix only passing host root in boot stage with new mount
fs: Fix uninitialized 'offp' in statmount_string()
Five fixes addressing PREEMPT_RT compatibility and locking issues. Three
commits fix potential deadlocks and sleeps in atomic contexts on RT kernels by
converting locks to raw spinlocks and ensuring IRQ work runs in hard-irq
context. The remaining two fix unsafe locking in the debug dump path and a
variable dereference typo.

Now target is removed from nvme_fc_ctrl_free() which is the ctrl->ref
release handler. And even admin queue is unquiesced there, this way
is definitely wrong because the ctr->ref is grabbed when submitting
command.
And Marco observed that nvme_fc_ctrl_free() can be called from request
completion code path, and trigger kernel warning since request completes
from softirq context.
Fix the issue by moveing target removal into nvme_fc_delete_ctrl(),
which is also aligned with nvme-tcp and nvme-rdma.
Patch originally proposed by Ming Lei, then modified to move the tagset
removal down to after nvme_fc_delete_association() after further testing.
