Hi Bob,

[auto build test ERROR on v4.3-rc7 -- if it's inappropriate base, please suggest rules for selecting the more suitable base]

config: x86_64-allyesconfig (attached as .config)
# save the attached .config to linux build tree
make ARCH=x86_64

Note: the linux-review/Bob-Liu/xen-block-multi-hardware-queues-rings-support/20151102-122806 HEAD b29fe44b095649f8faddc4474daba13199c1f5e0 builds fine.
It only hurts bisectibility.

All errors (new ones prefixed by >>):
