No idea. Code looks all different in 3.10.

Never seen in my log collection from kissb, which doesn't build
chroma_defconfig.

Fixed in v3.7-rc6:

    HID: microsoft: do not use compound literal - fix build

blackfin/defconfig:

sh/defconfig:
drivers/built-in.o: In function `fb_mmap':
fbmem.c:(.text+0x5e8): undefined reference to `vm_iomap_memory'

Both look similar and might be easy to fix if someone knows what is wrong.

Fixed in v3.9:

That one might be tricky (or simple if someone knows what is wrong).
