After applying this patch, and building things, I get the following
errors:

drivers/built-in.o: In function `ram_console_write':
ram_console.c:(.text+0x1690b9): undefined reference to `persistent_ram_write'

What went wrong?

I've now applied the first 3 patches in this series to my tree, plus the
2 others from the linux-next tree, so care to just fix up these last
three and resend them?

thanks,
