I don't mind. tcrypt these days isn't used so much for correctness
testing. It's mostly being used for speed testing. A secondary
use is to instantiate templates.

I think it may be needed for those split-SG test cases where
we deliberately create a buffer that straddles a page boundary.

It doesn't really matter because in FIPS mode when a correctness
test fails the kernel panics.

The returning -EAGAIN is irrelevant in FIPS mode. It's more of
an aid in normal mode when you use tcrypt for speed testing.
