split mmap
This is a straightforward split of do_mmap_pgoff() into two functions: - do_mmap_pgoff() checks the parameters, and calculates the vma flags. Then it calls - mmap_region(), which does the actual mapping Signed-off-by: Miklos Szeredi <mszeredi@suse.cz> Acked-by: Peter Zijlstra <a.p.zijlstra@chello.nl> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
