Luoqi Chen 645682fd40 Add a per-signal flag to mark handlers registered with osigaction, so we ... can provide the correct context to each signal handler. Fix broken sigsuspend(): don't use p_oldsigmask as a flag, use SAS_OLDMASK as we did before the linuxthreads support merge (submitted by bde). Move ps_sigstk from to p_sigacts to the main proc structure since signal stack should not be shared among threads. Move SAS_OLDMASK and SAS_ALTSTACK flags from sigacts::ps_flags to proc::p_flag. Move PS_NOCLDSTOP and PS_NOCLDWAIT flags from proc::p_flag to procsig::ps_flag. Reviewed by: marcel, jdp, bde		1999-10-11 20:33:17 +00:00
