[ Upstream commit c954b252dee956d33ee59f594710af28fb3037d9 ]
This patch is to fix an issue when simd is not usable that data mismatch may occur. The fix is to register algs as SIMD modules so that the algorithm is excecuted when SIMD instructions is usable. Called gcm_update() to generate the final digest if needed.
A new module rfc4106(gcm(aes)) is also added.
Fixes: cdcecfd9991f ("crypto: p10-aes-gcm - Glue code for AES/GCM stitched implementation")

crypto: powerpc/p10-aes-gcm - Re-write AES/GCM stitched implementationadded that function...
Ah, thanks, I'll go drop this patch from everywhere.
OK.
Looking at the queue, it looks like a prereq for un-BROKEN-ing the module in the next patch: 8b6c1e466eec crypto: powerpc/p10-aes-gcm - Add dependency on CRYPTO_SIMDand re-enable CRYPTO_AES_GCM_P10
Dropping the two, this one has to be dropped too: 3574a5168ff3 crypto: aes-gcm-p10 - Use the correct bit to test for P10
thanks,
