Linus Torvalds 8d561baae5 - Remove a transitional asm/cpuid.h header which was added only as
a fallback during cpuid helpers reorg
 
 - Initialize reserved fields in the SVSM page validation calls structure
   to zero in order to allow for future structure extensions
 
 - Have the sev-guest driver's buffers used in encryption operations be
   in linear mapping space as the encryption operation can be offloaded
   to an accelerator
 
 - Have a read-only MSR write when in an AMD SNP guest trap to the
   hypervisor as it is usually done. This makes the guest user experience
   better by simply raising a #GP instead of terminating said guest
 
 - Do not output AVX512 elapsed time for kernel threads because the data
   is wrong and fix a NULL pointer dereferencing in the process
 
 - Adjust the SRSO mitigation selection to the new attack vectors
