When CRYPTO_DEV_HISI_SEC=y, below compilation error is found after 'commit894b68d8be("crypto: hisilicon/des - switch to new verification routines")': drivers/crypto/hisilicon/sec/sec_algs.o: In function `sec_alg_skcipher_setkey_des_cbc': sec_algs.c:(.text+0x11f0): undefined reference to `des_expand_key' drivers/crypto/hisilicon/sec/sec_algs.o: In function `sec_alg_skcipher_setkey_des_ecb': sec_algs.c:(.text+0x1390): undefined reference to `des_expand_key' make: *** [vmlinux] Error 1 This because DES library has been moved to lib/crypto in this commit '04007b0e6cbb ("crypto: des - split off DES library from generic DES cipher driver")'. Fix this by selecting CRYPTO_LIB_DES in CRYPTO_DEV_HISI_SEC.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
