Subject: crc32c: include acconfig.h to fix ceph_crc32c_aarch64()
X-Git-Tag: v12.1.0~264^2
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=67d3049b02b014ed205b44437d2377d138d3ab0d;p=ceph.git

crc32c: include acconfig.h to fix ceph_crc32c_aarch64()

HAVE_ARMV8_CRC is defined by "acconfig.h". so we need to include it for
the definition.

it's a regresssion introduced by 2a3382f. in that change,
crc32c_intel_baseline.h was removed from crc32.cc, and that header
includes accconfig.h indirectly. that's why we will have a dummy
ceph_crc32c_aarch64() which always returns 0. the dummy implementation
was intended to please the compiler. but we can probably just drop it in
future as a cleanup.
