Hi all,

After merging the tip tree, today's linux-next build (x86_64 allmodconfig)
failed like this:

arch/x86/crypto/blake2s-core.S: Assembler messages:
arch/x86/crypto/blake2s-core.S:50: Error: invalid character '(' in mnemonic
arch/x86/crypto/blake2s-core.S:176: Error: invalid character '(' in mnemonic
arch/x86/crypto/blake2s-core.S:180: Error: invalid character '(' in mnemonic
arch/x86/crypto/blake2s-core.S:257: Error: invalid character '(' in mnemonic

Caused by commit

ed0356eda153 ("crypto: blake2s - x86_64 SIMD implementation")

from the crypto tree interacting with commit

6dcc5627f6ae ("x86/asm: Change all ENTRY+ENDPROC to SYM_FUNC_*")

from the tip tree.

I have applied the following merge fix patch.
