d3a993d46b Improve *access*() parameter name consistency.
The current code mixes the use of `flags' and `mode'. This is a bit
confusing, since the faccessat() function as a `flag' parameter to store
the AT_ flag.

Make this less confusing by using the same name as used in the POSIX
specification -- `amode'.

af5bf12239 Now that all system calls are MPSAFE, retire the SYF_MPSAFE flag used to
mark system calls as being MPSAFE:
- Stop conditionally acquiring Giant around system call invocations.
- Remove all of the 'M' prefixes from the master system call files.
- Remove support for the 'M' prefix from the script that generates the
  syscall-related files from the master system call files.
- Don't explicitly set SYF_MPSAFE when registering nfssvc.

95e7d19dfa - Explicitly lock Giant to protect the fields in the svr4_strm structure
except for s_family (which is read-only once after it is set when the
  structure is created).
- Mark svr4_sys_ioctl(), svr4_sys_getmsg(), and svr4_sys_putmsg() MPSAFE.

52d639a953 Add conditional VFS Giant locking to svr4_sys_fchroot() and mark it MPSAFE.
Also, call change_dir() instead of doing part of it inline (this now adds
a mac_check_vnode_chdir() call) to match fchdir() and call
mac_check_vnode_chroot() to match chroot().  Also, use the change_root()
function to do the actual change root to match chroot().

a3616b117c Make svr4_sys_waitsys() a lot less ugly and mark it MPSAFE.
- If the WNOWAIT flag isn't specified and either of WEXITED or WTRAPPED is
  set, then just call kern_wait() and let it do all the work.  This means
  that this function no longer has to duplicate the work to teardown
  zombies that is done in kern_wait().  Instead, if the above conditions
  aren't true, then it uses a simpler loop to implement WNOWAIT and/or
  tracing for only stopped or continued processes.  This function still
  has to duplicate code from kern_wait() for the latter two cases, but
  those are much simpler.
- Sync the code to handle the WCONTINUED and WSTOPPED cases with the
  equivalent code in kern_wait().
- Fix several places that would return with the proctree lock still held.
- Lock the current process to prevent lost wakeup races when blocking.

be5747d5b5 - Add conditional VFS Giant locking to getdents_common() (linux ABIs),
ibcs2_getdents(), ibcs2_read(), ogetdirentries(), svr4_sys_getdents(),
  and svr4_sys_getdents64() similar to that in getdirentries().
- Mark ibcs2_getdents(), ibcs2_read(), linux_getdents(), linux_getdents64(),
  linux_readdir(), ogetdirentries(), svr4_sys_getdents(), and
  svr4_sys_getdents64() MPSAFE.

bb639715d4 Use kern_shmctl() in svr4_sys_shmctl() and drop use of the stackgap. Mark

49d409a108 - Add a kern_semctl() helper function for __semctl(). It accepts a pointer
to a copied-in copy of the 'union semun' and a uioseg to indicate which
  memory space the 'buf' pointer of the union points to.  This is then used
  in linux_semctl() and svr4_sys_semctl() to eliminate use of the stackgap.
- Mark linux_ipc() and svr4_sys_semsys() MPSAFE.

f3596e3370 Introduce a new field in the syscalls.master file format to hold the
audit event identifier associated with each system call, which will
be stored by makesyscalls.sh in the sy_auevent field of struct sysent.
For now, default the audit identifier on all system calls to AUE_NULL,
but in the near future, other BSM event identifiers will be used.  The
mapping of system calls to event identifiers is many:one due to
multiple system calls that map to the same end functionality across
compatibility wrappers, ABI wrappers, etc.

2ca25ab53e Fix the ABI wrappers to use kern_fcntl() rather than calling fcntl()

the syscalls using these wrappers MP safe where appropriate.

ac2b067b9a Change the 'exit()' system call to 'sys_exit()'. This avoids overlapping
gcc's internal exit() prototypes and the (futile) hackery that we did to
try and avoid warnings.  main() was renamed for similar reasons.
Remove an exit related hack from makesyscalls.sh.

43914915de Fixed the "created from" lines generated from this file. makesyscalls.sh

8bc3445472 Fixed the return type and args struct tag for exit(). They were wrong in
all emulators.  These entries were unused, so the bug had no effect, but
the the args struct tag will be used to calculate sy_nargs correctly.

6d6fd92936 SVR4 emulator source files now take their compilation options from
opt_global.h and opt_svr4.h, instead of from the command line.  This
brings them in-line with most of the rest of the kernel.

svr4_ioctl.c has also failed to compile with debugging for a while
now;  fixed by adding systm.h and socketvar.

Some svr4 source files are automatically generated from syscalls.master;
these have been committed as consequential changes, otherwise everyone
will have to "make svr4_sysent.c".

Changes:

sys/svr4/svr4.h			include opt_global.h and opt_svr4.h
sys/svr4/svr4_ioctl.c		include svr4.h, sys/systm.h and sys/socketvar.h
sys/svr4/svr4_ipc.c		include svr4.h
sys/svr4/svr4_resource.c 	include svr4.h
sys/svr4/svr4_socket.c		include svr4.h
sys/svr4/svr4_ttold.c		include svr4.h
sys/svr4/syscalls.master	include svr4.h
sys/svr4/svr4_syscallnames.c	dependent on syscalls.master
sys/svr4/svr4_sysent.c		dependent on syscalls.master
sys/svr4/svr4_syscall.h		dependent on syscalls.master
sys/svr4/svr4_proto.h		dependent on syscalls.master
sys/modules/svr4/Makefile	create opt_global.h and opt_svr4.h

ea5216bcc7 Remove unnecessary includes.
phk's script walked through .c and .h files, but some of the ones on
the list are actually derived from sys/svr4/syscalls.master.  Make
the necessary changes here and the others will implicitly follow...
