there should be an #else here i think, which maps find_next_bit to
__find_next_bit / etc.
No, that is intentional: architectures are expected to either set
CONFIG_GENERIC_FIND_NEXT_BIT, or provide their own implementation of
find_next_bit.
indeed, you are right.
This version runs fine on qemu.
great - i've queued it up into x86.git.
