[PATCH] mm: consolidate get_order
Someone mentioned that almost all the architectures used basically the same implementation of get_order. This patch consolidates them into asm-generic/page.h and includes that in the appropriate places. The exceptions are ia64 and ppc which have their own (presumably optimised) versions.
