+Subject: [PATCH 2/4] i386, x86_64, ppc: fix switch fallthrough cases with GCC7
+
+In util/getroot and efidisk slightly modify exitsing comment to mostly
+retain it but still make GCC7 compliant with respect to fall through
+annotation.
+
+In grub-core/lib/xzembed/xz_dec_lzma2.c it adds same comments as
+upstream.
+
+In grub-core/tests/setjmp_tets.c declare functions as "noreturn" to
+suppress GCC7 warning.
+
+In grub-core/gnulib/regexec.c use new __attribute__, because existing
+annotation is not recognized by GCC7 parser (which requires that comment
+immediately precedes case statement).
+
+Otherwise add FALLTHROUGH comment.
+
