    [PATCH] Hugepage consolidation · 63551ae0
    David Gibson authored
    A lot of the code in arch/*/mm/hugetlbpage.c is quite similar.  This patch
    attempts to consolidate a lot of the code across the arch's, putting the
    combined version in mm/hugetlb.c.  There are a couple of uglyish hacks in
    order to covert all the hugepage archs, but the result is a very large
    reduction in the total amount of code.  It also means things like hugepage
    lazy allocation could be implemented in one place, instead of six.
    Tested, at least a little, on ppc64, i386 and x86_64.
    	- this patch changes the meaning of set_huge_pte() to be more
    	  analagous to set_pte()
    	- does SH4 need s special huge_ptep_get_and_clear()??
