Merge tag 'x86_apic_for_6.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 apic updates from Dave Hansen: "This includes a very thorough rework of the 'struct apic' handlers. Quite a variety of them popped up over the years, especially in the 32-bit days when odd apics were much more in vogue. The end result speaks for itself, which is a removal of a ton of code and static calls to replace indirect calls. If there's any breakage here, it's likely to be around the 32-bit museum pieces that get light to no testing these days. Summary: - Rework apic callbacks, getting rid of unnecessary ones and coalescing lots of silly duplicates. - Use static_calls() instead of indirect calls for apic->foo() - Tons of cleanups an crap removal along the way" * tag 'x86_apic_for_6.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (64 commits) x86/apic: Turn on static calls x86/apic: Provide static call infrastructure for APIC callbacks x86/apic: Wrap IPI calls into helper functions x86/apic: Mark all hotpath APIC callback wrappers __always_inline x86/xen/apic: Mark apic __ro_after_init x86/apic: Convert other overrides to apic_update_callback() x86/apic: Replace acpi_wake_cpu_handler_update() and apic_set_eoi_cb() x86/apic: Provide apic_update_callback() x86/xen/apic: Use standard apic driver mechanism for Xen PV x86/apic: Provide common init infrastructure x86/apic: Wrap apic->native_eoi() into a helper x86/apic: Nuke ack_APIC_irq() x86/apic: Remove pointless arguments from [native_]eoi_write() x86/apic/noop: Tidy up the code x86/apic: Remove pointless NULL initializations x86/apic: Sanitize APIC ID range validation x86/apic: Prepare x2APIC for using apic::max_apic_id x86/apic: Simplify X2APIC ID validation x86/apic: Add max_apic_id member x86/apic: Wrap APIC ID validation into an inline ...
