Hi,
I'm seeing lots of build failures in mm/madvise.c.

Is Minchin's patch only partially applied or is it just missing some pieces?

a. mm/madvise.c needs to #include <linux/uio.h>

b. looks like the sys_process_madvise() prototype in <linux/syscalls.h>
has not been updated:

In file included from ../mm/madvise.c:11:0:
../include/linux/syscalls.h:239:18: error: conflicting types for ‘sys_process_madvise’
asmlinkage long sys##name(__MAP(x,__SC_DECL,__VA_ARGS__)) \

thanks.
