Jan said, you're free to not accept a patch removing the config option
until the filesystem is gone for good. I just feel like it's easier to remove
ReiserFS from all defconfigs in one fell swoop.

I'm happy with this as it is. The issue with AVX registers being clobbered
when xsave isn't supported is unlikely to matter in practice, and can
be fixed with a patch afterwards.

LGTM. Now we get to deal with the errors coming from config.debug

mask registers. Please make that explicit
in your comment, or replace intrinsics with inline assembler to support those
registers.
Several x86 crypto routines use these larger registers which could overwrite
userspace registers. These modules aren't built by default, and may not be

Several x86 crypto routines use these larger registers which could overwrite
userspace registers. These modules aren't built by default, and may not be
available on UML. Even so, this issue is worth a comment, at the least.
On my system, lscpu within uml shows all the feature flags that are available
on the host system, which includes AVX extentions.
