39d61db0ed [PATCH] LOG2: Alter get_order() so that it can make use of ilog2() on a constant
Alter get_order() so that it can make use of ilog2() on a constant to produce
a constant value, retaining the ability for an arch to override it in the
non-const case.

fd4fd5aac1 [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.
