Subject: linux-next: build failure after merge of the final tree (akpm tree
 related)

Hi all,

After merging the final tree, today's linux-next build (sparc64 defconfig)
failed like this:

arch/sparc/kernel/sys_sparc_64.c: In function 'arch_get_unmapped_area':
arch/sparc/kernel/sys_sparc_64.c:92:16: error: unused variable 'start_addr' [-Werror=unused-variable]
arch/sparc/kernel/sys_sparc_64.c: In function 'arch_get_unmapped_area_topdown':
arch/sparc/kernel/sys_sparc_64.c:194:20: error: 'do_colour_align' undeclared (first use in this function)
arch/sparc/kernel/sys_sparc_64.c:194:20: note: each undeclared identifier is reported only once for each function it appears in
arch/sparc/kernel/sys_sparc_64.c:194:51: error: 'shm_align_mask' undeclared (first use in this function)

Caused by commit "mm: use vm_unmapped_area() on sparc64 architecture".  I
have reverted that commit for today (and the following fix patch).

arch/sparc/mm/hugetlbpage.c: In function 'hugetlb_get_unmapped_area_topdown':
arch/sparc/mm/hugetlbpage.c:63:25: error: unused variable 'vma' [-Werror=unused-variable]

Caused by commit "mm: use vm_unmapped_area() in hugetlbfs on sparc64
architecture".  I have reverted that commit for today.
