This patch was dropped because it was folded into kexec-load-and-relocate-purgatory-at-kernel-load-time.patch

From: Vivek Goyal <vgoyal@xxxxxxxxxx>
Subject: kexec-load-and-relocate-purgatory-at-kernel-load-time-fix
Set CRYPTO=y and CRYPTO_SHA256=y for all arch supporting kexec.
Generic kexec implementation now makes use of crypto API to calculate the
sha256 digest of loaded kernel segments (for new syscall kexec_file_load()).
That means one need to enforce that CRYPTO and CRYPTO_SHA256 are built in
for kexec to compile and for new syscall to work.
I created this dependency for x86 but forgot to do for other arches
supporting kexec. And ran into compilation failure reports from kbuild
test robot.
