Subject: 2007-07-31  Martin Hunt  <hunt@redhat.com>

	* */syscalls.stp: Added mmap functions.
	Continued moving common compatibility functions to
	the main tapset.

	* aux_syscalls.stp (_shmat_flags_str): New.
	(__get_compat_argv): New.

	* syscalls.stp (adjtimex): Just print hex argument.
	(compat_adjtimex): New.
	(clock_getres): Also probe compat_clock_getres.
	(clock_gettime): Also probe compat funcs.
	(compat_clock_nanosleep): New.
	(compat_execve): New.
	(fstatat): New.
	(get[e][gu]id): Also probe sys32.
	(getsockopt): Make optional. Also probe compat.
	(mmap, mmap2): These are arch-specific, so move to individual
	architecture subdirs.
	(compat_sys_msgctl): New.
	(compat_sys_msgrcv): New.
	(compat_sys_msgsnd): New.

	* syscalls.stp (pread32): Remove. It calls pread64 .
	(quotactl): Make optional.
	(recv): Probe correct function.
	(recvfrom): Fix args.
	(compat_sys_recvmsg): New.
	(semctl): Make optional.
	(compat_sys_semctl): New.
	(semget): Make optional.
	(semop): Make optional.

	(send): Make optional.
	(sendmsg): Make optional.
	(compat_sys_sendmsg): New.
	(sendto): Make optional.
	(setsockopt): Make optional. Add compat.
	(shmat): New.
	(compat_sys_shmat): New.
	(shmctl): New.
	(compat_sys_shmctl): New.
	(shmdt): New.
	(shmget): New.
	(shutdown): Make optional.
