| |
Hi Dan,
After merging the nvdimm tree, today's linux-next build (powerpc ppc64_defconfig) failed like this:
In file included from arch/powerpc/kernel/asm-offsets.c:22:0: include/linux/mman.h: In function 'calc_vm_flag_bits': include/linux/mman.h:109:48: warning: division by zero [-Wdiv-by-zero] ((bit1) <= (bit2) ? ((x) & (bit1)) * ((bit2) / (bit1)) \ ^ include/linux/mman.h:133:9: note: in expansion of macro '_calc_vm_trans' _calc_vm_trans(flags, MAP_SYNC, VM_SYNC ); ^ cc1: all warnings being treated as errors
and more like these ...
Caused by commit
ebd0722a382c ("mm: Define MAP_SYNC and VM_SYNC flags")
Not all architectures use asm-generic/mman.h
I have used the nvdimm tree from next-20171102 for today.
-- Cheers, Stephen Rothwell
