I take this back ... in next-20101011 the disease has spread:

fs/signalfd.c: In function ‘signalfd_copyinfo’:
fs/signalfd.c:109: error: ‘const struct <anonymous>’ has no member
named ‘_addr_lsb’
fs/signalfd.c:109: warning: type defaults to ‘int’ in declaration of ‘__pu_x’
fs/signalfd.c:109: error: ‘const struct <anonymous>’ has no member
named ‘_addr_lsb’

So today I have build problems :-(

A question about the naming/type of this new field. "lsb" sounds like
it might mean
"least significant byte (or perhaps bit)" ... why is the type "short"?
