Regarding the checkpatch warnings, I intentionally ignored these: WARNING: line over 80 characters #181: FILE: arch/x86/kernel/cpu/sgx/ioctl.c:547: + if (atomic_read(&encl->flags) & (SGX_ENCL_INITIALIZED | SGX_ENCL_DEAD)) { WARNING: line over 80 characters #248: FILE: arch/x86/kernel/cpu/sgx/reclaim.c:386: + (atomic_read(&encl->flags) & (SGX_ENCL_DEAD | SGX_ENCL_INITIALIZED))) total: 0 errors, 2 warnings, 181 lines checked The one in ioctl.c is ephemeral, i.e. won't exist once the whole series is squashed, and I felt the code in reclaim.c was more readable by letting the line poke out a few chars. That being said, I definitely don't care if you want to tweak the code to eliminate the warning.
