Merge tag 'x86_sgx_for_v5.17_rc1' of git://git./linux/kernel/git/tip/tip

Pull x86 SGX updates from Borislav Petkov:

 - 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
