Merge tag 'x86_misc_for_v7.1_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull misc x86 updates from Borislav Petkov:
- Reference the tip tree maintainer handbook directly from the relevant
MAINTAINERS file entries (covering timers, IRQ, locking, scheduling,
perf, x86, and others) so that contributors and tooling can know
where to look
- Enable interrupt remapping in defconfig, which is an architectural
requirement for x2APIC to function correctly on bare metal. Without
it, x2APIC was effectively enabled but non-functional.
- Ensure that drivers which register custom restart handlers (such as
those needed for SoC-based x86 devices like Intel Lightning Mountain)
are actually invoked during reboot, bringing x86 in line with how
other architectures handle this.
- Cleanups
* tag 'x86_misc_for_v7.1_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
MAINTAINERS: Add references to tip tree handbook
x86/64/defconfig: Add CONFIG_IRQ_REMAP
x86/reboot: Execute the kernel restart handler upon machine restart
x86/mtrr: Use kstrtoul() in parse_mtrr_spare_reg()
