Error compiling sun4i-emac.o: implicit declaration of function ‘writesl’

Hi Simon.

I was trying to build this kernel with some more stuff built as modules, and got this:

CC [M] drivers/net/ethernet/allwinner/sun4i-emac.o

Hacked KVM so it actually works. Thanks to @apritzel for remembering the bug and what to fix.

custom .config file (started with sun50iw1p1smp_linux_defconfig ), but with existing stuff not touched.

Any ideas? Some missing header includes?

I am using gcc 5.3.1-16, and doing native compilation.

Why do you need sun4i-emac? Makes no sense if you ask me and does not seem to support 64bit.
