[SRU][mantic:linux-gcp, lunar:linux-gcp][PATCH 0/2] SEV_SNP failure to init

[John Cabaj]

BugLink: https://bugs.launchpad.net/bugs/2037316

[Impact]

* Kernel fails to boot on SEV-SNP instances when compiled with GCC 12.3.0

[Fix]

* https://lore.kernel.org/lkml/20230912002703.3924521-1-acdunlap@google.com/

[Test Case]

* Compile tested
* Boot tested
* Tested by Google

[Where things could go wrong]

* Patches relatively isolated and maintain similar checking functionality, 
  just earlier in boot. Likely a low chance of regression.

Adam Dunlap (2):
  x86/sev-es: Allow copy_from_kernel_nofault in earlier boot
  x86/sev-es: Only set x86_virt_bits to correct value
