Merge tag 'x86_urgent_for_v5.12-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 fixes from Borislav Petkov:
"The freshest pile of shiny x86 fixes for 5.12:
- Add the arch-specific mapping between physical and logical CPUs to
fix devicetree-node lookups
- Restore the IRQ2 ignore logic
- Fix get_nr_restart_syscall() to return the correct restart syscall
number. Split in a 4-patches set to avoid kABI breakage when
backporting to dead kernels"
* tag 'x86_urgent_for_v5.12-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
x86/apic/of: Fix CPU devicetree-node lookups
x86/ioapic: Ignore IRQ2 again
x86: Introduce restart_block->arch_data to remove TS_COMPAT_RESTART
x86: Introduce TS_COMPAT_RESTART to fix get_nr_restart_syscall()
x86: Move TS_COMPAT back to asm/thread_info.h
kernel, fs: Introduce and use set_restart_fn() and arch_set_restart_data()
