af0121c2d3 kbuild: rust: add CONFIG_RUSTC_LLVM_VERSION
Each version of Rust supports a range of LLVM versions. There are cases where
we want to gate a config on the LLVM version instead of the Rust version.
Normalized cfi integer tags are one example [1].

The invocation of rustc-version is being moved from init/Kconfig to
scripts/Kconfig.include for consistency with cc-version.

e72a076c62 kbuild: fix issues with rustc-option
Fix a few different compiler errors that cause rustc-option to give
wrong results.

If KBUILD_RUSTFLAGS or the flags being tested contain any -Z flags, then
the error below is generated. The RUSTC_BOOTSTRAP environment variable
is added to fix this error.

	error: the option `Z` is only accepted on the nightly compiler
	help: consider switching to a nightly toolchain: `rustup default nightly`
	note: selecting a toolchain with `+toolchain` arguments require a rustup proxy;
	      see <https://rust-lang.github.io/rustup/concepts/index.html>
	note: for more information about Rust's stability policy, see
	      <https://doc.rust-lang.org/book/appendix-07-nightly-rust.html#unstable-features>
	error: 1 nightly option were parsed

Note that RUSTC_BOOTSTRAP is also defined in the top-level Makefile,
but Make-exported variables are unfortunately *not* inherited. That said,
this is changing as of commit 98da874c4303 ("[SV 10593] Export variables
to $(shell ...) commands"), which is part of Make 4.4.

The probe may also fail with the error message below. To fix it,
the /dev/null argument is replaced with a file containing the crate
attribute #![no_core]. The #![no_core] attribute ensures that rustc does
not look for the standard library. It's not possible to instead supply
a standard library (i.e. `core`) to rustc, as we need `rustc-option`
before the Rust standard library is compiled.

	error[E0463]: can't find crate for `std`
	  |
	  = note: the `aarch64-unknown-none` target may not be installed
	  = help: consider downloading the target with `rustup target add aarch64-unknown-none`
	  = help: consider building the standard library from source with `cargo build -Zbuild-std`

The -o and --out-dir parameters are altered to fix this warning:

	warning: ignoring --out-dir flag due to -o flag

The --sysroot flag is provided as we would otherwise require it to be
present in KBUILD_RUSTFLAGS. The --emit=obj flag is used to write the
resulting object file to /dev/null instead of writing it to a file
in $(TMPOUT).

I verified that the Kconfig version of rustc-option doesn't have the
same issues.

cc-option-yn and cc-disable-warning duplicate the compile command seen
a few lines above. These can be defined based on cc-option.

I also refactored rustc-option-yn in the same way, although there are
currently no users of it.

  execve("./postinst", ...) = -1 ENOEXEC (Exec format error)
  strace: exec: Exec format error

However running the scripts via shell does work (at least with bash)
because the shell attempts to execute the file as a shell script when
execve() fails.

b6c57b70a3 platform/x86: dell-laptop: Do not fail when encountering unsupported batteries
If the battery hook encounters a unsupported battery, it will
return an error. This in turn will cause the battery driver to
automatically unregister the battery hook.

On machines with multiple batteries however, this will prevent
the battery hook from handling the primary battery, since it will
always get unregistered upon encountering one of the unsupported
batteries.

Fix this by simply ignoring unsupported batteries.

c8d430db8e KVM/arm64 fixes for 6.12, take #1
- Fix pKVM error path on init, making sure we do not change critical
   system registers as we're about to fail
 
 - Make sure that the host's vector length is at capped by a value
   common to all CPUs
 
 - Fix kvm_has_feat*() handling of "negative" features, as the current
   code is pretty broken
 
 - Promote Joey to the status of official reviewer, while James steps
   down -- hopefully only temporarly

2a5fe5a016 x86/reboot: emergency callbacks are now registered by common KVM code
Guard them with CONFIG_KVM_X86_COMMON rather than the two vendor modules.
In practice this has no functional change, because CONFIG_KVM_X86_COMMON
is set if and only if at least one vendor-specific module is being built.
However, it is cleaner to specify CONFIG_KVM_X86_COMMON for functions that
are used in kvm.ko.

Reported-by: Linus Torvalds <torvalds@linux-foundation.org>
Fixes: 590b09b1d8 ("KVM: x86: Register "emergency disable" callbacks when virt is enabled")
Fixes: 6d55a94222 ("x86/reboot: Unconditionally define cpu_emergency_virt_cb typedef")

ea4290d77b KVM: x86: leave kvm.ko out of the build if no vendor module is requested
kvm.ko is nothing but library code shared by kvm-intel.ko and kvm-amd.ko.
It provides no functionality on its own and it is unnecessary unless one
of the vendor-specific module is compiled.  In particular, /dev/kvm is
not created until one of kvm-intel.ko or kvm-amd.ko is loaded.

Use CONFIG_KVM to decide if it is built-in or a module, but use the
vendor-specific modules for the actual decision on whether to build it.

This also fixes a build failure when CONFIG_KVM_INTEL and CONFIG_KVM_AMD
are both disabled.  The cpu_emergency_register_virt_callback() function
is called from kvm.ko, but it is only defined if at least one of
CONFIG_KVM_INTEL and CONFIG_KVM_AMD is provided.

8f602276d3 bcachefs fixes for 6.12-rc2
A lot of little fixes, bigger ones include:
 
 - bcachefs's __wait_on_freeing_inode() was broken in rc1 due to vfs
   changes, now fixed along with another lost wakeup
 - fragmentation LRU fixes; fsck now repairs successfully (this is the
   data structure copygc uses); along with some nice simplification.
 - Rework logged op error handling, so that if logged op replay errors
   (due to another filesystem error) we delete the logged op instead of
   going into an infinite loop)
 - Various small filesystem connectivitity repair fixes
 
 The final part of this patch series, fixing snapshots + unlinked file
 handling, is now out on the list - I'm giving that part of the series
 more time for user testing.

The reason for this error is physical_package_ids assigned by VMware VMM
are not continuous and have gaps. This will cause value returned by
topology_physical_package_id() to be more than topology_max_packages().

Here the allocation uses topology_max_packages(). The call to
topology_max_packages() returns maximum logical package ID not physical
ID. Hence use topology_logical_package_id() instead of
topology_physical_package_id().

72350ee0ea bcachefs: Kill snapshot arg to fsck_write_inode()
It was initially believed that it would be better to be explicit about
the snapshot we're updating when writing inodes in fsck; however, it
turns out that passing around the snapshot separately is more error
prone and we're usually updating the inode in the same snapshow we read
it from.

This is different from normal filesystem paths, where we do the update
in the snapshot of the subvolume we're in.

c7da5ee2e5 bcachefs: Check for unlinked inodes with dirents
link count works differently in bcachefs - it's only nonzero for files
with multiple hardlinks, which means we can also avoid checking it
except for files that are known to have hardlinks.

That means we need a few different checks instead; in particular, we
don't want fsck to delet a file that has a dirent pointing to it.

260af1562e bcachefs: Kill alloc_v4.fragmentation_lru
The fragmentation_lru field hasn't been needed since we reworked the LRU
btrees to use the btree write buffer; previously it was used to resolve
collisions, but the revised LRU btree uses the backpointer (the bucket)
as part of the key.

It should have been deleted at the time of the LRU rework; since it
wasn't, that left places for bugs to hide, in check/repair.

This fixes LRU fsck on a filesystem image helpfully provided by a user
who disappeared before I could get his name for the reported-by.

01bf5e3bd2 bcachefs: minor lru fsck fixes
check_lru_key() wasn't using write buffer updates for deleting bad lru
entries - dating from before the lru btree used the btree write buffer.

And when possibly flushing the btree write buffer (to make sure we're
seeing a real inconsistency), we need to be using the modern
bch2_btree_write_buffer_maybe_flush().

6b63a948a7 bcachefs: Add missing wakeup to bch2_inode_hash_remove()
This fixes two different bugs:

- Looser locking with the rhashtable means we need to recheck if the
  inode is still hashed after prepare_to_wait(), and add a corresponding
  wakeup after removing from the hash table.

- da18ecbf0f ("fs: add i_state helpers") changed the bit waitqueues
  used for inodes, and bcachefs wasn't updated and thus broke; this
  updates bcachefs to the new helper.

6121258c2b ext4: fix off by one issue in alloc_flex_gd()

==================================================================
EXT4-fs (dm-5): resizing filesystem from 7168 to 786432 blocks
------------[ cut here ]------------
kernel BUG at fs/ext4/resize.c:324!
CPU: 9 UID: 0 PID: 3576 Comm: resize2fs Not tainted 6.11.0+ #27
RIP: 0010:ext4_resize_fs+0x1212/0x12d0

==================================================================

While reviewing the patch, Honza found that when adjusting resize_bg in
alloc_flex_gd(), it was possible for flex_gd->resize_bg to be bigger than
flexbg_size.

The reproduction of the problem requires the following:

 o_group = flexbg_size * 2 * n;
 o_size = (o_group + 1) * group_size;
 n_group: [o_group + flexbg_size, o_group + flexbg_size * 2)
 o_size = (n_group + 1) * group_size;

Take n=0,flexbg_size=16 as an example:

              last:15
|o---------------|--------------n-|
o_group:0    resize to      n_group:30

The corresponding reproducer is:

img=test.img
rm -f $img
truncate -s 600M $img
mkfs.ext4 -F $img -b 1024 -G 16 8M
dev=`losetup -f --show $img`
mkdir -p /tmp/test
mount $dev /tmp/test
resize2fs $dev 248M

Delete the problematic plus 1 to fix the issue, and add a WARN_ON_ONCE()
to prevent the issue from happening again.

[ Note: another reproucer which this commit fixes is:

  img=test.img
  rm -f $img
  truncate -s 25MiB $img
  mkfs.ext4 -b 4096 -E nodiscard,lazy_itable_init=0,lazy_journal_init=0 $img
  truncate -s 3GiB $img
  dev=`losetup -f --show $img`
  mkdir -p /tmp/test
  mount $dev /tmp/test
  resize2fs $dev 3G
  umount $dev
  losetup -d $dev

04e6ce8f06 ext4: mark fc as ineligible using an handle in ext4_xattr_set()
Calling ext4_fc_mark_ineligible() with a NULL handle is racy and may result
in a fast-commit being done before the filesystem is effectively marked as
ineligible.  This patch moves the call to this function so that an handle
can be used.  If a transaction fails to start, then there's not point in
trying to mark the filesystem as ineligible, and an error will eventually be
returned to user-space.
