Subject: sha/asm/sha512-armv8.pl: fix big-endian support in __KERNEL__ case.
X-Git-Tag: OpenSSL_1_1_1-pre1~3008

sha/asm/sha512-armv8.pl: fix big-endian support in __KERNEL__ case.

In non-__KERNEL__ context 32-bit-style __ARMEB__/__ARMEL__ macros were
set in arm_arch.h, which is shared between 32- and 64-bit builds. Since
it's not included in __KERNEL__ case, we have to adhere to official
64-bit pre-defines, __AARCH64EB__/__AARCH64EL__.

[If we are to share more code, it would need similar adjustment.]
