The patch titled
powerpc: fix MAX_ORDER config problem
has been removed from the -mm tree. Its filename was
powerpc-fix-max_order-config-problem.patch
This patch was dropped because it was merged into mainline or a subsystem tree

Subject: powerpc: fix MAX_ORDER config problem
From: Stephen Rothwell <sfr@xxxxxxxxxxxxxxxx>
The allyesconfig (among others) build was giving this:
In file included from include/linux/gfp.h:4,
from include/linux/slab.h:14,
from include/linux/percpu.h:5,
from include2/asm/time.h:18,
from include2/asm/cputime.h:26,
from include/linux/sched.h:67,
from
arch/powerpc/kernel/asm-offsets.c:17:
include/linux/mmzone.h:791:2: error: #error Allocator MAX_ORDER exceeds SECTION_SIZE
Kconfig options are order depenendent, so move the setting of
FORCE_MAX_ZONEORDER to after the setting of PPC_64K_PAGES. Also add an
explicit !PPC_64K_PAGES.
