The HAVE_CFI_ICALL_NORMALIZE_INTEGERS option has some tricky conditions when KASAN or GCOV are turned on, as in that case we need some clang and rustc fixes [1][2] to avoid boot failures. The intent with the current setup is that you should be able to override the check and turn on the option if your clang/rustc has the fix. However, this override does not work in practice. Thus, use the new RUSTC_LLVM_VERSION to correctly implement the check for whether the fix is available. Additionally, remove KASAN_HW_TAGS from the list of incompatible options. The CFI_ICALL_NORMALIZE_INTEGERS option is incompatible with KASAN because LLVM will emit some constructors when using KASAN that are assigned incorrect CFI tags. These constructors are emitted due to use of -fsanitize=kernel-address or -fsanitize=kernel-hwaddress that are respectively passed when KASAN_GENERIC or KASAN_SW_TAGS are enabled. However, the KASAN_HW_TAGS option relies on hardware support for MTE instead and does not pass either flag. (Note also that KASAN_HW_TAGS does not `select CONSTRUCTORS`.)

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.

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. Fixes: c4229743 ("kbuild: rust: Define probing macros for rustc") Co-developed-by:

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. Reviewed-by:

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:

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.

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().

Initially it was thought that we just wanted to ignore errors from logged op replay, but it turns out we do need to catch -EROFS, or we'll go into an infinite loop. Signed-off-by:Kent Overstreet <kent.overstreet@linux.dev>

These shouldn't always be fatal errors - logged op resume, in particular, and we want it as a parameter there. Signed-off-by: -

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. Signed-off-by: -

We want to check for this early so it can be reattached if necessary in check_unreachable_inodes(); better than letting it be deleted and having the children reattached, losing their filenames. Signed-off-by: -

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. Signed-off-by:
