Hi all,

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

drivers/crypto/hisilicon/qm.c: Assembler messages:
drivers/crypto/hisilicon/qm.c:334: Error: no such instruction: `ldp %rdx,%rcx,%bl'
drivers/crypto/hisilicon/qm.c:335: Error: no such instruction: `stp %rdx,%rcx,%al'
drivers/crypto/hisilicon/qm.c:336: Error: number of operands mismatch for `ds'

Caused by commit

  62c455ca853e ("crypto: hisilicon - add HiSilicon ZIP accelerator support")

I also got the following warnings:

This latter from commit

  dfed0098ab91 ("crypto: hisilicon - add hardware SGL support")

I have disabled CRYPTO_DEV_HISI_ZIP for now.  You should not select
CONFIG options that have dependencies (without also depending on the
same things and being very careful).
