   # HEAD: 02b670c1f88e78f42a6c5aee155c7b26960ca054 x86/mm: Remove broken vsyscall emulation code from the page fault code

Misc fixes:

 - Remove the broken vsyscall emulation code from
   the page fault code.

 - Fix kexec crash triggered by certain SEV RMP
   table layouts.

 - Fix unchecked MSR access error when disabling
   the x2APIC via iommu=off.

 Thanks,

	Ingo
