Switch LogBuffer from Coherent<[u8]> (unsized) to
Coherent<[u8; LOG_BUFFER_SIZE]> (sized). The buffer size is a
compile-time constant (RM_LOG_BUFFER_NUM_PAGES * GSP_PAGE_SIZE), so a
fixed-size array is more precise and avoids the need for the runtime
length parameter of zeroed_slice().

The last step of virtscsi_handle_event() is to call
virtscsi_kick_event(), which calls INIT_WORK on its own work
item. INIT_WORK resets the work item's data bits to 0.
If this occurs while the work item is being flushed by
cancel_work_sync(), then kernel/workqueue.c/work_offqd_enable triggers a
kernel warning, as it expects the "disable" bit to be 1:

[ * DRM_GEM_SHMEM_HELPER is a tristate; when a module driver selects it,

built into vmlinux and can't reference symbols from a module,
causing link errors.
Thus, add RUST_DRM_GEM_SHMEM_HELPER bool Kconfig that selects
DRM_GEM_SHMEM_HELPER, forcing it built-in when Rust drivers need it;
use cfg(CONFIG_RUST_DRM_GEM_SHMEM_HELPER) for the shmem module.
* Add cfg_attr(not(CONFIG_RUST_DRM_GEM_SHMEM_HELPER), expect(unused))
on pub(crate) use impl_aref_for_gem_obj and BaseObjectPrivate, so
that unused warnings are suppressed when shmem is not enabled.

Since the ChaCha permutation is invertible, the local variable
'permuted_state' is sufficient to compute the original 'state', and thus
the key, even after the permutation has been done.
While the kernel is quite inconsistent about zeroizing secrets on the
stack (and some prominent userspace crypto libraries don't bother at all
since it's not guaranteed to work anyway), the kernel does try to do it
as a best practice, especially in cases involving the RNG.
Thus, explicitly zeroize 'permuted_state' before it goes out of scope.

Replace the deprecated[1] strncpy() with strscpy() in
transport_dump_vpd_proto_id(), transport_dump_vpd_assoc(),
transport_dump_vpd_ident_type(), and transport_dump_vpd_ident().
All four functions follow the same pattern: a local
buf[VPD_TMP_BUF_SIZE] (254 bytes) is zeroed with memset(), populated
via sprintf()/snprintf() (always NUL-terminated), then conditionally
copied to p_buf with strncpy(). The p_buf destination is used as a
C string by all callers in target_core_configfs.c: strlen(buf) and
sprintf(page+len, "%s", buf) to build sysfs output.
NUL-padding is not required: callers in target_core_configfs.c
pre-zero p_buf with memset() or initializer before calling these
functions, and consume p_buf only as a NUL-terminated C string via
strlen() and "%s", never exposing trailing bytes.
No behavioral change: the source buf is always NUL-terminated and
shorter than VPD_TMP_BUF_SIZE, so strscpy() produces identical output.

reenqueueing but the BPF scheduler cannot directly iterate or move tasks
from them. %SCX_DSQ_GLOBAL is similar but also doesn't support
reenqueueing because it maps to multiple per-node DSQs, making the scope
difficult to define.

Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
The current probe time ownership check for Soft Reserved memory based
solely on CXL window intersection is insufficient. dax_hmem probing is not
always guaranteed to run after CXL enumeration and region assembly, which
can lead to incorrect ownership decisions before the CXL stack has
finished publishing windows and assembling committed regions.
Introduce deferred ownership handling for Soft Reserved ranges that
intersect CXL windows. When such a range is encountered during the
initial dax_hmem probe, schedule deferred work to wait for the CXL stack
to complete enumeration and region assembly before deciding ownership.
Once the deferred work runs, evaluate each Soft Reserved range
individually: if a CXL region fully contains the range, skip it and let
dax_cxl bind. Otherwise, register it with dax_hmem. This per-range
ownership model avoids the need for CXL region teardown and
alloc_dax_region() resource exclusion prevents double claiming.
Introduce a boolean flag dax_hmem_initial_probe to live inside device.c
so it survives module reload. Ensure dax_cxl defers driver registration
until dax_hmem has completed ownership resolution. dax_cxl calls
dax_hmem_flush_work() before cxl_driver_register(), which both waits for
the deferred work to complete and creates a module symbol dependency that
forces dax_hmem.ko to load before dax_cxl.

Move hmem/ earlier in the dax Makefile so that hmem_init() runs before
dax_cxl.
In addition, defer registration of the dax_cxl driver to a workqueue
instead of using module_cxl_driver(). This ensures that dax_hmem has
an opportunity to initialize and register its deferred callback and make
ownership decisions before dax_cxl begins probing and claiming Soft
Reserved ranges.
Mark the dax_cxl driver as PROBE_PREFER_ASYNCHRONOUS so its probe runs
out of line from other synchronous probing avoiding ordering
dependencies while coordinating ownership decisions with dax_hmem.
