Hi,
 
When booting latest kernel with the CONFIG_CRYPTO_SHA1_MB enabled, I
observe a panic.
 
After having a quick look, on reverting the following patches, I am able
to complete the booting process.
aec4d0e301f17bb143341c82cc44685b8af0b945
8691ccd764f9ecc69a6812dfe76214c86ac9ba06
68874ac3304ade7ed5ebb12af00d6b9bbbca0a16
 
Of the 3 patches, aec4d0e301f17bb143341c82cc44685b8af0b945 seems wrong.
The r10 to r15 registers are used in sha1_x8_avx2.S, which is called
from sha1_mb_mgr_flush_avx2.S.
 
I do not think the functionality of the SHA1-MB crypto algorithm has
been tested after applying these changes. (I am not sure if any of the
other crypto algorithms have been affected by these changes).
 
Thanks,
Megha
