x86/sgx: Fix NULL pointer dereference on non-SGX systems (2022-01-07 08:47:23 -0800)
---------------------------------------------------------------- - Add support for handling hw errors in SGX pages: poisoning, recovering from poison memory and error injection into SGX pages
- A bunch of changes to the SGX selftests to simplify and allow of SGX features testing without the need of a whole SGX software stack
- Add a sysfs attribute which is supposed to show the amount of SGX memory in a NUMA node, similar to what /proc/meminfo is to normal memory
- The usual bunch of fixes and cleanups too
