Subject: [PATCH] crypto: wp512 - disable kmsan checks in
wp512_process_buffer()
The memory sanitizer causes excessive register spills in this function:
crypto/wp512.c:782:13: error: stack frame size (2104) exceeds limit (2048) in 'wp512_process_buffer' [-Werror,-Wframe-larger-than]
Assume that this one is safe, and mark it as needing no checks to
get the stack usage back down to the normal level.
