I wrote a patch to clean up get_order(). When I'd done a rough cut of it
I did some google searches and found that Andrey Panin had already wrote
a nearly equivelant patch (down to some of the same identifier names :-)
over a year ago for kernel 2.5.10:
  http://www.ussg.iu.edu/hypermail/linux/kernel/0204.3/0720.html

I combined some ideas from his patch into mine. He really deserves
the credit since he came up with it first.

Anyway, all architectures but two (ia64, ppc) use the same get_order()
inline function in asm-*/page.h. This patch adds a asm-generic/get_order.h
file that all of them now #include.

1. For the majority of archs that DON'T have their own assembly version
   of get_order() we now provide it in one place - lib/get_order.c

   This is one place where my patch is different than Andrey's - he left
   it as an inline like it is currently. I personally don't think it's
   worth inlining - it IS very short (22 bytes on i386) but it's still
   longer than a function call. It's rarely (if ever) called from
   performance cricial points. Usually it's just used in setup/teardown
   code.

   Architectures with inline-assembly implementations of get_order()
   continue to use them instead.

2. We now compute get_order(CONSTANT) at compile-time. There aren't
   too many cases of this, but there are some. Now that it's free
   it may get useful in more places.

When Andrey posted his patch it didn't seem to generate any discussion.
Any interest this time?
