06d5e032ad include/asm-generic/page.h: calculate virt_to_page and page_to_virt via predefined macro
On NOMMU architectures, if physical memory doesn't start from 0,
ARCH_PFN_OFFSET is defined to generate page index in mem_map array.
Because virtual address is equal to physical address, PAGE_OFFSET is
always 0.  virt_to_page and page_to_virt should not index page by
PAGE_OFFSET directly.

b7a0556e0f fixed generic page.h for non-zero PAGE_OFFSET
asm-generic/page.h had several problems when used with a non-zero PAGE_OFFSET.
This patch adds a default ARCH_PFN_OFFSET and fixes the __va, __pa, and
pfn_valid macros to work with non-zero PAGE_OFFSETs.

5c01b46bb6 asm-generic: add generic NOMMU versions of some headers
Memory management in generic is highly architecture specific,
but on NOMMU architectures, it is mostly trivial, so just
add a default implementation in asm-generic that applies
to all NOMMU architectures.

The two files cache.h and cacheflush.h can possibly also
be used by architectures that have an MMU but never require
flushing the cache or have cache lines larger than 32 bytes.

5b17e1cd89 asm-generic: rename page.h and uaccess.h
The current asm-generic/page.h only contains the get_order
function, and asm-generic/uaccess.h only implements
unaligned accesses. This renames the file to getorder.h
and uaccess-unaligned.h to make room for new page.h
and uaccess.h file that will be usable by all simple
(e.g. nommu) architectures.

38f3323037 Revert "[PATCH] LOG2: Alter get_order() so that it can make use of ilog2() on a constant"
This reverts commit 39d61db0ed.

The commit was buggy in multiple ways:
 - the conversion to ilog2() was incorrect to begin with
 - it tested the wrong #defines, so on all architectures but FRV you'd
   never see the bug except for constant arguments.
 - the new "get_order()" macro used its arguments multiple times, and
   didn't even parenthesize them properly
 - despite the comments, it was not true that you could use it for
   constant initializers, since not all architectures even use the
   generic page.h header file.

All of the problems are individually fixable, but it all boils down to:
better just revert it, and re-do it from scratch.

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.
