When sysmem reservation occurs exactly at the end of an existing block that block is deleted, because it is incorrectly included in the range of memblocks to remove. Fix that by skipping such block.

Concentrate code to modify totalram_pages into the mm core, so the arch memory initialized code doesn't need to take care of it. With these changes applied, only following functions from mm core modify global variable totalram_pages: free_bootmem_late(), free_all_bootmem(), free_all_bootmem_node(), adjust_managed_page_count().
With this patch applied, it will be much more easier for us to keep totalram_pages and zone->managed_pages in consistence.

Address more review comments from last round of code review. 1) Enhance free_reserved_area() to support poisoning freed memory with pattern '0'. This could be used to get rid of poison_init_mem() on ARM64. 2) A previous patch has disabled memory poison for initmem on s390 by mistake, so restore to the original behavior. 3) Remove redundant PAGE_ALIGN() when calling free_reserved_area().

include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h
percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies.
percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion.
http://userweb.kernel.org/~tj/misc/slabh-sweep.py
The script does the followings.
* Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h.
* When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order.
* If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file.
The conversion was done in the following steps.
1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files.
2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files.
3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind.
4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually.
5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary.
6. percpu.h was updated not to include slab.h.
7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq).
* x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig
8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point.
Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

arches: drop superfluous casts in nr_free_pages() callers

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.

xtensa: cope with ram beginning at higher addresses
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_SIZE
The 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.

xtensa: don't make bootmem bitmap larger than required
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.

xtensa: fix init_bootmem_node() argument order
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.

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().

SL*B: drop kmem cache argument from constructor
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.c
This is flag day, yes.
