Subject: [RFC PATCH v1 00/19] kill free_all_bootmem() and clean up VALID_PAGE()

Commit 600cc5b7f6 "mm: Kill NO_BOOTMEM version free_all_bootmem_node()"
has kill free_all_bootmem_node() for NO_BOOTMEM.

Currently the usage pattern for free_all_bootmem_node() is like:
for_each_online_pgdat(pgdat)
	free_all_bootmem_node(pgdat);

It's equivalent to free_all_bootmem(), so this patchset goes one
step further to kill free_all_bootmem_node() for BOOTMEM too.

This patchset also tries to clean up code and comments related to
VALID_PAGE() because it has been removed from kernel long time ago.

Patch 1-11:
	Kill free_all_bootmem_node()
Patch 12-16:
	Clean up code and comments related to VALID_PAGE()
Patch 17:
	Fix a minor build warning for m68k
Patch 18:
	merge Alpha's mem_init() for UMA and NUMA.
Patch 19:
	call register_page_bootmem_info_node() from mm core

This patch is based on patchset at
http://marc.info/?l=linux-mm&m=136525931917910&w=2
