Subject: mm/sparsemem: use PAGES_PER_SECTION to remove redundant nr_pages parameter
X-Git-Tag: v3.13-rc1~106^2~217
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=85b35feaecd4d2284505b22708795bc1f03fc897;p=pandora-kernel.git

mm/sparsemem: use PAGES_PER_SECTION to remove redundant nr_pages parameter

For below functions,

- sparse_add_one_section()
- kmalloc_section_memmap()
- __kmalloc_section_memmap()
- __kfree_section_memmap()

they are always invoked to operate on one memory section, so it is
redundant to always pass a nr_pages parameter, which is the page numbers
in one section.  So we can directly use predefined macro PAGES_PER_SECTION
instead of passing the parameter.
