Subject: [PATCH 0/4] Basic recovery for machine checks inside SGX
Date:   Thu,  8 Jul 2021 11:14:19 -0700

Cover the easy cases:
1) memory errors reported by patrol scrubber in unused SGX pages
2) machine checks due to poison consumption from SGX_PAGE_TYPE_REG
   pages
3) When poison is consumed in an enclave inside a guest, just kill
   the guest.

Tony Luck (4):
  x86/sgx: Track phase and type of SGX EPC pages
  x86/sgx: Add basic infrastructure to recover from errors in SGX memory
  x86/sgx: Hook sgx_memory_failure() into mainline code
  x86/sgx: Add hook to error injection address validation
