+Subject: [PATCH] os: detect PMULL support before enabling accelerated crc32c
+ on ARM
+
+Issue #1239 shows a crash on a FUJITSU/A64FX ARM platform at the
+following line:
+
+crc/crc32c-arm64.c:
+ 64                 t1 = (uint64_t)vmull_p64(crc1, k2);
+
+On armv8 PMULL crypto instructions like vmull_p64 are defined as
+optional (see
+https://github.com/google/crc32c/pull/6#issuecomment-328713398 and
+https://github.com/dotnet/runtime/issues/35143#issuecomment-617263508 ).
+
+Avoid the crash by gating use of the hardware accelerated ARM crc32c
+path behind runtime detection of PMULL.
+
+Fixes: https://github.com/axboe/fio/issues/1239
