[ Original patch from Arnd (see [0]) ]

Hi,

as reported in [1] this is the last patch we "ClangBuiltLinux folks"
need to be full compliant with LLVM_IAS=1 (for example with Linux
v5.8-rc4).

These two commits entered recently cryptodev-2.6.git:

commit 44069737ac9625a0f02f0f7f5ab96aae4cd819bc
"crypto: aesni - add compatibility with IAS"

commit 3347c8a079d67af21760a78cc5f2abbcf06d9571
"crypto: aesni - Fix build with LLVM_IAS=1"

With these three patches we are full compliant with LLVM_IAS=1 in
x86/crypto tree.

Feel free to add my:

   Tested-by: Sedat Dilek <sedat.dilek@...il.com>

Thanks.

Regards,
