In 5.15.0-1045, only loading enclaves with XFRM set to 3 works, sgx_encl_init returns EINVAL. The only reason this wouldn't work properly is if sgx_drv_init thinks XSAVE isn't enabled. This works fine in 5.15.0-1043.

Likely cause:
1045 adds this patch: https://github.com/torvalds/linux/commit/b81fac906a8f9e682e513ddd95697ec7a20878d4 . This later patch indicates that the former patch introduced some ordering problems. https://github.com/torvalds/linux/commit/2c66ca3949dc701da7f4c9407f2140ae425683a5 . That later patch isn't applied to 1045.
