Subject: [PATCH] mm/hugetlb: move hugetlb_sysctl_init() to the __init section

From: Marc Herbert <Marc.Herbert@...ux.intel.com>

hugetlb_sysctl_init() is only invoked once by an __init function and is
merely a wrapper around another __init function so there is not reason
to keep it.

Fixes the following warning when toning down some GCC inline options:

 WARNING: modpost: vmlinux: section mismatch in reference:
   hugetlb_sysctl_init+0x1b (section: .text) ->
     __register_sysctl_init (section: .init.text)
