+Subject: [PATCH] Linux ppc64le ieee128 compat: Do not redefine __asm on
+ external headers
+
+There is an external assembly declaration extension in GNU C that glibc
+uses when building with ieee128 floating point support on ppc64le.
+Marking that as volatile makes no sense, so the build breaks.
+
+It does not make sense to only mark this as volatile on Linux, since if
+do not want the compiler reordering things on Linux, we do not want the
+compiler reordering things on any other platform, so we stop treating
+Linux specially and just manually inline the CPP macro so that we can
+eliminate it. This should fix the build on ppc64le.
+
+Closes openzfs/zfs#14308
