CVS commit: [nathanw_sa] src/lib/libpthread/arch/powerpc

[Nathan J Williams <nathanw%netbsd.org@localhost>]

Module Name:    src
Committed By:   nathanw

Modified Files:
        src/lib/libpthread/arch/powerpc [nathanw_sa]: pthread_switch.S

Log Message:
Rewrite pthread__switch() and adjust pthread__locked_switch() to
avoid storing the new saved-context pointer while still using the old
stack. This avoids a race condition with pthread__find_interrupted()
where a thread could lose its old state if it was interrupted in a
certain window in pthread__switch().
