Subject: [PATCH] mempolicy.h: Remove unnecessary header file inclusions

Originally, linux/mempolicy.h included linux/pagemap.h because vma_migratable()
was implemented inline within the header, requiring mapping_gfp_mask()
function to implement vma_migratable(). Now that vma_migratable() is only
declared in linux/mempolicy.h and its implementation has been moved to mempolicy.c,
the inclusion of linux/pagemap.h in the header is no longer necessary.

Additionally, since mempolicy.c includes internal.h, and internal.h already
includes linux/pagemap.h, so there is no need to modify mempolicy.c after
removing the direct inclusion of linux/pagemap.h from linux/mempolicy.h
