+Subject: [PATCH] m68k: Fix build with -mcpu=68040 or higher (BZ 30740)
+
+GCC currently does not define __mc68020__ for -mcpu=68040 or higher,
+which memcpy/memmove assumptions. Since this memory copy optimization
+seems only intended for m68020, disable for other m680X0 variants.
+
+Checked on a build for m68k-linux-gnu target mc68020 and mc68040.

+Subject: [PATCH] m68k: Use M68K_SCALE_AVAILABLE on __mpn_lshift and
+ __mpn_rshift
+
+This patch adds a new macro, M68K_SCALE_AVAILABLE, similar to gmp
+scale_available_p (mpn/m68k/m68k-defs.m4) that expand to 1 if a
+scale factor can be used in addressing modes. This is used
+instead of __mc68020__ for some optimization decisions.
+
+Checked on a build for m68k-linux-gnu target mc68020 and mc68040.
