Pull TIF bit unification updates from Thomas Gleixner:
"A set of changes to consolidate the generic TIF (thread info flag)
bits accross architectures.
All architectures define the same set of generic TIF bits. This makes
it pointlessly hard to add a new generic TIF bit or to change an
existing one.
Provide a generic variant and convert the architectures which utilize
the generic entry code over to use it. The TIF space is divided into
16 generic bits and 16 architecture specific bits, which turned out to
provide enough space on both sides"
