v2: - fix performance issues in sha256-avx2-asm.S and sha512-avx2-asm.S (Eric) Many of the x86 crypto functions use RBP as a temporary register. This breaks frame pointer convention, and breaks stack traces when unwinding from an interrupt in the crypto code. Convert most* of them to leave RBP alone. These pass the crypto boot tests for me. Any further testing would be appreciated! [*] There are still a few crypto files left that need fixing, but the fixes weren't trivial and nobody reported unwinder warnings about them yet, so I'm skipping them for now.
