Add change_page_attr to change page attributes for the kernel linear map.
Fix AGP driver to use change_page_attr for the AGP buffer.
Clean up AGP driver a bit (only tested on i386/VIA+AMD)
Change ioremap_nocache to use change_page_attr to avoid mappings with
conflicting caching attributes.

Since namespace.h needs the contents of dcache, task struct and
semaphores, it seems sensible to include these two files into
namespace.h.
For the future: If the task_struct in sched.h is split into its own
include file, namespace.h could include this file, but namespace.h
will also need asm/semaphore.h

This moves the vmalloc wrappers from <linux/vmalloc.h> into mm/vmalloc.c.
Doing this will later allow us to remove <linux/mm.h> from <linux/vmalloc.h>,
along with some other #include fixups.

This patch removes VALID_PAGE(), as the test was always too late for
discontinous memory configuration. It is replaced with pfn_valid()/
virt_addr_valid(), which are used to test the original input value.
Other helper functions:
pte_pfn() - extract the page number from a pte
pfn_to_page()/page_to_pfn() - convert a page number to/from a page struct

asm/pgtable.h and/or asm/pgalloc.h to asm/cacheflush.h, and
tlb flushing routines to asm/tlbflush.h.
