Merge tag 'x86-irq-2021-06-29' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 interrupt related updates from Thomas Gleixner: - Consolidate the VECTOR defines and the usage sites. - Cleanup GDT/IDT related code and replace open coded ASM with proper native helper functions. * tag 'x86-irq-2021-06-29' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/kexec: Set_[gi]dt() -> native_[gi]dt_invalidate() in machine_kexec_*.c x86: Add native_[ig]dt_invalidate() x86/idt: Remove address argument from idt_invalidate() x86/irq: Add and use NR_EXTERNAL_VECTORS and NR_SYSTEM_VECTORS x86/irq: Remove unused vectors defines
