Commit 9259826ccb8165f797e4c2c9d17925b41af5f6ae ("res_counter: remove
include of cgroup.h from res_counter.h") removed the indirect inclusion of
<linux/errno.h>, breaking the build on m68k and sparc:

In file included from mm/memcontrol.c:29:
include/linux/res_counter.h: In function ‘res_counter_set_limit’:
include/linux/res_counter.h:203: error: ‘EBUSY’ undeclared (first use in this function)
include/linux/res_counter.h:203: error: (Each undeclared identifier is reported only once
include/linux/res_counter.h:203: error: for each function it appears in.)
