3.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Geert Uytterhoeven <geert@linux-m68k.org>
commit a8abbca6617e1caa2344d2d38d0a35f3e5928b79 upstream.
Fix the m32r link error:
LD arch/m32r/boot/compressed/vmlinux arch/m32r/boot/compressed/misc.o: In function `zlib_updatewindow': misc.c:(.text+0x190): undefined reference to `memcpy' misc.c:(.text+0x190): relocation truncated to fit: R_M32R_26_PLTREL against undefined symbol `memcpy' make[5]: *** [arch/m32r/boot/compressed/vmlinux] Error 1
by adding our own implementation of memcpy().
