------------------
From: Geert Uytterhoeven <geert@xxxxxxxxxxxxxx>
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().
