Hi Christophe,
Hmm, I'm not so sure I like this very much. I think it's important for
these tests to fail when an arch tries to hook up the function to the
vDSO, but it's still not exported for some reason. This also regresses
the AR
The chacha vDSO selftest doesn't check the way the counter is handled
by __arch_chacha20_blocks_nostack(). It indirectly checks that the
counter is writen on exit and read back on new entry, but it doesn't
check that the format is correct. It has led to an invisible erroneous
implementation on powe
Without -O2, the generated code for testing chacha function is awful.
GCC even implements rol32() as a function instead of just using the
rotlwi instruction, that function is 20 instructions long.

Hi Christophe,
Hmm, I'm not so sure I like this very much. I think it's important for
these tests to fail when an arch tries to hook up the function to the
vDSO, but it's still not exported for some reason. This also regresses
the ARCH=x86_64 vs ARCH=x86 thing, which SRCARCH fixes.
What about, in
