lib/nodemask: inline next_node_in() and node_random()
The functions are pretty thin wrappers around find_bit engine, and keeping them in c-file prevents compiler from small_const_nbits() optimization, which must take place for all systems with MAX_NUMNODES less than BITS_PER_LONG (default is 16 for me). Moving them to header file doesn't blow up the kernel size: add/remove: 1/2 grow/shrink: 9/5 up/down: 968/-88 (880) CC: Andy Shevchenko <andriy.shevchenko@linux.intel.com> CC: Benjamin Herrenschmidt <benh@kernel.crashing.org> CC: Michael Ellerman <mpe@ellerman.id.au> CC: Paul Mackerras <paulus@samba.org> CC: Rasmus Villemoes <linux@rasmusvillemoes.dk> CC: Stephen Rothwell <sfr@canb.auug.org.au> CC: linuxppc-dev@lists.ozlabs.org Signed-off-by: Yury Norov <yury.norov@gmail.com>
