Subject: x86, efi: Fix processor-specific memcpy() build error
From: Matt Fleming <[email protected]>
commit 0f905a43ce955b638139bd84486194770a6a2c08 upstream.
Building for Athlon/Duron/K7 results in the following build error,
arch/x86/boot/compressed/eboot.o: In function `__constant_memcpy3d':
eboot.c:(.text+0x385): undefined reference to `_mmx_memcpy'
arch/x86/boot/compressed/eboot.o: In function `efi_main':
eboot.c:(.text+0x1a22): undefined reference to `_mmx_memcpy'
because the boot stub code doesn't link with the kernel proper, and
therefore doesn't have access to the 3DNow version of memcpy. So,
follow the example of misc.c and #undef memcpy so that we use the
version provided by misc.c.
