asm-generic: page.h: Remove useless get_user_page and free_user_page
They are not symmetric with each other, neither are used in real world (can not be found by grep command in source code root directory), so remove them.

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.

fixed generic page.h for non-zero PAGE_OFFSET

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.

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.

[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.

[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.
