If these msrs are read by the emulator (e.g due to 'force emulation' prefix),
SVM code currently fails to extract the corresponding segment bases,
and return them to the emulator.

Fix that.

Grab kvm->srcu when processing KVM_SET_VCPU_EVENTS, as KVM will forcibly
leave nested VMX/SVM if SMM mode is being toggled, and leaving nested VMX
reads guest memory.

Note, kvm_vcpu_ioctl_x86_set_vcpu_events() can also be called from KVM_RUN
via sync_regs(), which already holds SRCU.  I.e. trying to precisely use
kvm_vcpu_srcu_read_lock() around the problematic SMM code would cause
problems.  Acquiring SRCU isn't all that expensive, so for simplicity,
grab it unconditionally for KVM_SET_VCPU_EVENTS.

Error out if kvm_mmu_reload() fails when pre-faulting memory, as trying to
fault-in SPTEs will fail miserably due to root.hpa pointing at garbage.

Note, kvm_mmu_reload() can return -EIO and thus trigger the WARN on -EIO
in kvm_vcpu_pre_fault_memory(), but all such paths also WARN, i.e. the
WARN isn't user-triggerable and won't run afoul of warn-on-panic because
the kernel would already be panicking.

fuse_notify_store(), unlike fuse_do_readpage(), does not enable page
zeroing (because it can be used to change partial page contents).

So fuse_notify_store() must be more careful to fully initialize page
contents (including parts of the page that are beyond end-of-file)
before marking the page uptodate.

The current code can leave beyond-EOF page contents uninitialized, which
makes these uninitialized page contents visible to userspace via mmap().

This is an information leak, but only affects systems which do not
enable init-on-alloc (via CONFIG_INIT_ON_ALLOC_DEFAULT_ON=y or the
corresponding kernel command line parameter).

Pull bcachefs fixes from Kent OverstreetL

 - New on disk format version, bcachefs_metadata_version_disk_accounting_inum

   This adds one more disk accounting counter, which counts disk usage
   and number of extents per inode number. This lets us track
   fragmentation, for implementing defragmentation later, and it also
   counts disk usage per inode in all snapshots, which will be a useful
   thing to expose to users.

 - One performance issue we've observed is threads spinning when they
   should be waiting for dirty keys in the key cache to be flushed by
   journal reclaim, so we now have hysteresis for the waiting thread, as
   well as improving the tracepoint and a new time_stat, for tracking
   time blocked waiting on key cache flushing.

Although there are several patches improving the extent map shrinker,
there are still reports of too frequent shrinker behavior, taking too
much CPU for the kswapd process.

So let's only enable extent shrinker for now, until we got more
comprehensive understanding and a better solution.

  nvdimm/pmem: Set dax flag for all 'PFN_MAP' cases

io_uring_cqe's user_data field refers to `sqe->data`, but io_uring_sqe
does not have a data field. Fix the comment to say `sqe->user_data`.

Pull rust fixes from Miguel Ojeda:

 - Fix '-Os' Rust 1.80.0+ builds adding more intrinsics (also tweaked in
   upstream Rust for the upcoming 1.82.0).

 - Fix support for the latest version of rust-analyzer due to a change
   on rust-analyzer config file semantics (considered a fix since most
   developers use the latest version of the tool, which is the only one
   actually supported by upstream). I am discussing stability of the
   config file with upstream -- they may be able to start versioning it.

 - Fix GCC 14 builds due to '-fmin-function-alignment' not skipped for
   libclang (bindgen).

 - A couple Kconfig fixes around '{RUSTC,BINDGEN}_VERSION_TEXT' to
   suppress error messages in a foreign architecture chroot and to use a
   proper default format.

 - Clean 'rust-analyzer' target warning due to missing recursive make
   invocation mark.

 - Clean Clippy warning due to missing indentation in docs.

 - Clean LLVM 19 build warning due to removed 3dnow feature upstream.

Pull RISC-V fixes from Palmer Dabbelt:

 - reintroduce the text patching global icache flush

 - fix syscall entry code to correctly initialize a0, which manifested
   as a strace bug

 - XIP kernels now map the entire kernel, which fixes boot under at
   least DEBUG_VIRTUAL=y

 - initialize all nodes in the acpi_early_node_map initializer

 - fix OOB access in the Andes vendor extension probing code

 - A new key for scalar misaligned access performance in hwprobe, which
   correctly treat the values as an enum (as opposed to a bitmap)

Pull tracing fixes from Steven Rostedt:
 "A couple of fixes for tracing:

   - Prevent a NULL pointer dereference in the error path of RTLA tool

   - Fix an infinite loop bug when reading from the ring buffer when
     closed. If there's a thread trying to read the ring buffer and it
     gets closed by another thread, the one reading will go into an
     infinite loop when the buffer is empty instead of exiting back to
     user space"
