[PATCH 06/10] powerpc: remove GCC version check for UPD_CONSTR

From: Nick Desaulniers <hidden>
Date: 2021-09-10 23:41:20
Also in: linuxppc-dev, lkml
Subsystem: linux for powerpc (32-bit and 64-bit), the rest · Maintainers: Madhavan Srinivasan, Michael Ellerman, Linus Torvalds

Now that GCC 5.1 is the minimum supported version, we can drop this
workaround for older versions of GCC. This adversely affected clang,
too.
