Linus Torvalds 8426226217 - Have the Automatic IBRS setting check on AMD does not falsely fire in
the guest when it has been set already on the host
 
 - Make sure cacheinfo structures memory is allocated to address a boot NULL
   ptr dereference on Intel Meteor Lake which has different numbers of subleafs
   in its CPUID(4) leaf
 
 - Take care of the GDT restoring on the kexec path too, as expected by
   the kernel
 
 - Make sure SMP is not disabled when IO-APIC is disabled on the kernel
   cmdline
 
 - Add a PGD flag _PAGE_NOPTISHADOW to instruct machinery not to propagate
   changes to the kernelmode page tables, to the user portion, in PTI
 
 - Mark Intel Lunar Lake as affected by an issue where MONITOR wakeups can get
   lost and thus user-visible delays happen
 
 - Make sure PKRU is properly restored with XRSTOR on AMD after a PRKU write of
   0 (WRPKRU) which will mark PKRU in its init state and thus lose the
   actual buffer
