Merge tag 'x86-urgent-2021-09-26' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 fixes from Thomas Gleixner:
"A set of fixes for X86:
- Prevent sending the wrong signal when protection keys are enabled
and the kernel handles a fault in the vsyscall emulation.
- Invoke early_reserve_memory() before invoking e820_memory_setup()
which is required to make the Xen dom0 e820 hooks work correctly.
- Use the correct data type for the SETZ operand in the EMQCMDS
instruction wrapper.
- Prevent undefined behaviour to the potential unaligned accesss in
the instruction decoder library"
