Commit 96177299416dbccb73b54e6b344260154a445375 ("Drop free_pages()")
modified nr_free_pages() to return 'unsigned long' instead of 'unsigned
int'. This made the casts to 'unsigned long' in most callers superfluous,
so remove them.[akpm@linux-foundation.org: coding-style fixes]

The current assumption of the memory code is that the first RAM PFN in
the system is 0.Adjust the relevant code to play well with setups where memory starts
at higher addresses, indicated by PLATFORM_DEFAULT_MEM_START.The new memory model looks like this:
+----------+--+----------------------+----------------+
| | | | |
| | | RAM | |
| | | | |
+----------+--+----------------------+----------------+
| | | | |
+- PFN 0 | +- min_low_pfn +- max_low_pfn +- max_pfn
|
+- ARCH_PFN_OFFSET
+- PLATFORM_DEFAULT_MEM_START >> PAGE_SIZEThe memory map contains pages starting from pfn ARCH_PFN_OFFSET up to
max_low_pfn. The only zone used right now will span exactly the same
region.Usually, ARCH_PFN_OFFSET and min_low_pfn are the same value. Handle
them separately for robustness. Gapping pages will be in the memory
map but marked as reserved and won't be touched.Signed-off-by: Johannes Weiner

If min_low_pfn is non-zero, the bitmap reserved for bootmem is bigger
than needed. The number of pages bootmem has to maintain is the range
from min_low_pfn to max_low_pfn.For now it has only been a theoretical mistake, min_low_pfn was always
zero.Signed-off-by: Johannes Weiner

The second argument to init_bootmem_node() is the PFN to place the
bootmem bitmap at and the third argument is the first PFN on the node.This is currently backwards but never made any problems as both values
were always zero.Signed-off-by: Johannes Weiner

Remove arch-specific show_mem() in favor of the generic version.
This also removes the following redundant information display:
- free pages, printed by show_free_areas()
- pages in swapcache, printed by show_swap_cache_info()where show_mem() calls show_free_areas(), which calls
show_swap_cache_info().Signed-off-by: Johannes Weiner

Kmem cache passed to constructor is only needed for constructors that are
themselves multiplexeres. Nobody uses this "feature", nor does anybody uses
passed kmem cache in non-trivial way, so pass only pointer to object.Non-trivial places are:
arch/powerpc/mm/init_64.c
arch/powerpc/mm/hugetlbpage.cThis is flag day, yes.

Add support for processors that have cache-aliasing issues, such as
the Stretch S5000 processor. Cache-aliasing means that the size of
the cache (for one way) is larger than the page size, thus, a page
can end up in several places in cache depending on the virtual to
physical translation. The method used here is to map a user page
temporarily through the auto-refill way 0 and of of the DTLB.
We probably will want to revisit this issue and use a better
approach with kmap/kunmap.Signed-off-by: Chris Zankel

The Xtensa port contained many header files that were never needed. This
rather lengthy patch removes all those files. Unfortunately, there were
many dependencies that needed to be updated, so this patch touches quite a
few source files.Signed-off-by: Chris Zankel

set_page_count usage outside mm/ is limited to setting the refcount to 1.
Remove set_page_count from outside mm/, and replace those users with
init_page_count() and set_page_refcounted().This allows more debug checking, and tighter control on how code is allowed
to play around with page->_count.Signed-off-by: Nick Piggin
