Hi Andrew, After merging the akpm-current tree, today's linux-next build (bfin TCM-BF537_defconfig and many others) failed like this: (.init.text+0x5f8): undefined reference to `ioremap_huge_init' Caused by commit 45eaed3ec431 ("lib/ioremap.c: add huge I/O map capability interfaces"). lib/ioremp.o is only built if CONFIG_MMU is set ... -- Cheers, Stephen Rothwell sfr@canb.auug.org.au
