+ sh-mm-drop-allocate_pgdat.patch added to mm-new branch

The patch titled
     Subject: sh: mm: drop allocate_pgdat()
has been added to the -mm mm-new branch.  Its filename is
     sh-mm-drop-allocate_pgdat.patch

This patch will shortly appear at
     https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patches/sh-mm-drop-allocate_pgdat.patch

This patch will later appear in the mm-new branch at
    git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Note, mm-new is a provisional staging ground for work-in-progress
patches, and acceptance into mm-new is a notification for others take
notice and to finish up reviews.  Please do not hesitate to respond to
review feedback and post updated versions to replace or incrementally
fixup patches in mm-new.

The mm-new branch of mm.git is not included in linux-next

If a few days of testing in mm-new is successful, the patch will me moved
into mm.git's mm-unstable branch, which is included in linux-next

Before you just go and hit "reply", please:
   a) Consider who else should be cc'ed
   b) Prefer to cc a suitable mailing list as well
   c) Ideally: find the original patch on the mailing list and do a
      reply-to-all to that, adding suitable additional cc's

*** Remember to use Documentation/process/submit-checklist.rst when testing your code ***

The -mm tree is included into linux-next via various
branches at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm
and is updated there most days

allocate_pgdat() function used to allocate the node data structure and
initialize its node_start_pfn and node_spanned_pages fields.

Without CONFIG_NUMA there is no need to allocate the node data and setting
node_start_pfn and node_spanned_pages are redundant because they are
anyway overwritten later by core MM.

Remove allocate_pgdat() function.
