2024-10-30alienware-wmi: alienware_wmax_command() is now input size agnosticKurt Borja
alienware_wmax_command() now takes void * and size_t instead of struct wmax_basic_args to extend support to new WMAX methods. Also int *out_data was changed to u32 *out_data, because new interface specifies u32 as output parameter and all previous callers would pass u32 * regardless.

Convert all platform drivers below drivers/platform/x86/ to use .remove(), with the eventual goal to drop struct platform_driver::remove_new().

2024-09-29x86: kvm: fix build errorLinus Torvalds
The cpu_emergency_register_virt_callback() function is used unconditionally by the x86 kvm code, but it is declared (and defined) conditionally: #if IS_ENABLED(CONFIG_KVM_INTEL) || IS_ENABLED(CONFIG_KVM_AMD) void cpu_emergency_register_virt_callback(cpu_emergency_virt_cb *callback); ... leading to a build error when neither KVM_INTEL nor KVM_AMD support is enabled: arch/x86/kvm/x86.c: In function ‘kvm_arch_enable_virtualization’: arch/x86/kvm/x86.c:12517:9: error: implicit declaration of function ‘cpu_emergency_register_virt_callback’ [-Wimplicit-function-declaration] 12517 | cpu_emergency_register_virt_callback(kvm_x86_ops.emergency_disable_virtualization_cpu); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ arch/x86/kvm/x86.c: In function ‘kvm_arch_disable_virtualization’: arch/x86/kvm/x86.c:12522:9: error: implicit declaration of function ‘cpu_emergency_unregister_virt_callback’ [-Wimplicit-function-declaration] 12522 | cpu_emergency_unregister_virt_callback(kvm_x86_ops.emergency_disable_virtualization_cpu); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Fix the build by defining empty helper functions the same way the old cpu_emergency_disable_virtualization() function was dealt with for the same situation. Maybe we could instead have made the call sites conditional, since the callers (kvm_arch_{en,dis}able_virtualization()) have an empty weak fallback. I'll leave that to the kvm people to argue about, this at least gets the build going for that particular config.

Pull more bcachefs updates from Kent Overstreet: "Assorted minor syzbot fixes, and for bigger stuff: Fix two disk accounting rewrite bugs: - Disk accounting keys use the version field of bkey so that journal replay can tell which updates have been applied to the btree. This is set in the transaction commit path, after we've gotten our journal reservation (and our time ordering), but the BCH_TRANS_COMMIT_skip_accounting_apply flag that journal replay uses was incorrectly skipping this for new updates generated prior to journal replay. This fixes the underlying cause of an assertion pop in disk_accounting_read. - A couple of fixes for disk accounting + device removal. Checking if acocunting replicas entries were marked in the superblock was being done at the wrong point, when deltas in the journal could still zero them out, and then additionally we'd try to add a missing replicas entry to the superblock without checking if it referred to an invalid (removed) device. A whole slew of repair fixes: - fix infinite loop in propagate_key_to_snapshot_leaves(), this fixes an infinite loop when repairing a filesystem with many snapshots - fix incorrect transaction restart handling leading to occasional "fsck counted ..." warnings - fix warning in __bch2_fsck_err() for bkey fsck errors - check_inode() in fsck now correctly checks if the filesystem was clean - there shouldn't be pending logged ops if the fs was clean, we now check for this - remove_backpointer() doesn't remove a dirent that doesn't actually point to the inode - many more fsck errors are AUTOFIX" * tag 'bcachefs-2024-09-28' of git://evilpiepirate.org/bcachefs: (35 commits) bcachefs: check_subvol_path() now prints subvol root inode bcachefs: remove_backpointer() now checks if dirent points to inode bcachefs: dirent_points_to_inode() now warns on mismatch bcachefs: Fix lost wake up bcachefs: Check for logged ops when clean bcachefs: BCH_FS_clean_recovery bcachefs: Convert disk accounting BUG_ON() to WARN_ON() bcachefs: Fix BCH_TRANS_COMMIT_skip_accounting_apply bcachefs: Check for accounting keys with bversion=0 bcachefs: rename version -> bversion bcachefs: Don't delete unlinked inodes before logged op resume bcachefs: Fix BCH_SB_ERRS() so we can reorder bcachefs: Fix fsck warnings from bkey validation bcachefs: Move transaction commit path validation to as late as possible bcachefs: Fix disk accounting attempting to mark invalid replicas entry bcachefs: Fix unlocked access to c->disk_sb.sb in bch2_replicas_entry_validate() bcachefs: Fix accounting read + device removal bcachefs: bch_accounting_mode bcachefs: fix transaction restart handling in check_extents(), check_dirents() bcachefs: kill inode_walker_entry.seen_this_pos ...
