Subject: [PATCH v3 0/7] Basic recovery for machine checks inside SGX

Changes since v2:

Jarkko:
	1) Don't provide a dummy non-NULL value for "owner" of new SGX EPC
	   pages at the call site. Instead change sgx_alloc_epc_page() to
	   provide a non-NULL value.
	2) Add description of the new debugfs files to sgx.rst
	   [Added a whole section on uncorrected memory errors]

Tony Luck (7):
  x86/sgx: Provide indication of life-cycle of EPC pages
  x86/sgx: Add infrastructure to identify SGX EPC pages
  x86/sgx: Initial poison handling for dirty and free pages
  x86/sgx: Add SGX infrastructure to recover from poison
  x86/sgx: Hook sgx_memory_failure() into mainline code
  x86/sgx: Add hook to error injection address validation
  x86/sgx: Add documentation for SGX memory errors
