[PATCH] ppc64 need HPAGE_SHIFT when huge pages disabled
With the new powerpc architecture we don't seem to be able to disable huge pages anymore. mm/built-in.o(.toc1+0xae0): undefined reference to `HPAGE_SHIFT' make: *** [.tmp_vmlinux1] Error 1 We seem to need to define HPAGE_SHIFT to something when HUGETLB_PAGE isn't defined. This patch defines it to PAGE_SHIFT when we have no support.
