Hi André,

Instead of explicitly defining set_mempolicy_home_node as sys_ni_sycall in
the syscall table, define it as the real syscall entry point,
sys_set_mempolicy_home_node. As per commit fdb7d9b7acd0 ("alpha: remove
DISCONTIGMEM and NUMA"), alpha doesn't have NUMA support, so none of the
mempolicy sycalls will ever be compiled for alpha, resulting in the
COND_SYSCALL() fallback being used to result in the sys_ni_syscall.

There's no function change here, but this step helps to unify the syscall
tables and create a common table to rule them all.

Looks good to me.
