Revert vadvise(2) removal

This system call was used in legacy Lisp code, that was inherited to modern
age and still compiled against supported compat layers (e.g. in clisp,
oaklisp, Franz Lisp).

It used to instruct the kernel about paging policy (G/C aware, flush etc).

Newly compiled code (assuming that it will detect vadvise()) will use the
libc stub for vadvise(). The headers for this interface are gone.

vadvise(2) could be marked as COMPAT_80, but as long as we support ultrix,
sunos or aout68k ABI, don't bother with this.

compat/sunos: Drop SYS_vadvise

The (o)vadvise syscall is dummy since the beginning of NetBSD.

compat/sunos: Drop SYS_sbrk

sbrk - change data segment size

This syscall is dummy since the inception of the project.

compat sunos: Drop the sstk(2) syscall

sstk(2) has never been implemented by the NetBSD kernel.

Fix dup/dup2/dup3 argument types (u_int -> int).

One more overcomplex ENOSYS bites the dust.

branches: 1.74.4;
Convert the syscalls.master to a format from which it is easier
to parse and generate the compat name and basename (e.g. __stat50
and stat). Use this to autogenerate __RENAME()'s to the rump_syscalls
header so that they can be called e.g. rump_sys_socket() instead
of rump_sys___socket30().

UNIMPL police

Update for compat_50 stuff. (compile test only)

merge christos-time_t

Make the emulations, exec formats, coredump, NFS, and the NFS server
into modules. By and large this commit:

- shuffles header files and ifdefs
- splits code out where necessary to be modular
- adds module glue for each of the components
- adds/replaces hooks for things that can be installed at runtime

branches: 1.69.2; 1.69.4;
Include <sys/sched.h> before <sys/syscallargs.h> for cpuset_t.

branches: 1.68.6; 1.68.8; 1.68.12; 1.68.14; 1.68.16;
Convert all the system call entry points from:
int foo(struct lwp *l, void *v, register_t *retval)
to:
int foo(struct lwp *l, const struct foo_args *uap, register_t *retval)
Fixup compat code to not write into 'uap' and (in some cases) to actually
pass a correctly formatted 'uap' structure with the right name to the
next routine.
A few 'compat' routines that just call standard ones have been deleted.
All the 'compat' code compiles (along with the kernels required to test
build it).
98% done by automated scripts.

branches: 1.67.16; 1.67.24; 1.67.28;
Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.

branches: 1.66.2;
Merge newlock2 to head.

branches: 1.65.2;
Don't conditionalize *sys_ptrace. The lack of sys_ptrace will be dealt
with differently.

Update for options PTRACE.

request the COMPAT_30 getfh in the master files. (Changes to the generated
ones would be lost.)

branches: 1.62.4; 1.62.8;

nuke trailing whitespace

Merge the nathanw_sa branch.

move the COMPAT_SUNOS SO_BROADCAST hack out of uipc_socket.c into the
compat/sunos code. besides being cleaner this allows the sunos LKM
to properly work without any special kernel hacks.

branches: 1.58.2;
use _KERNEL_OPT.

branches: 1.57.2;
Get rid of the damn EMUL_GET* flags.

Add the %% separators.

LKMify

rename some unimplimented (because they are OLD in sunos) syscalls to avoid confusion.

branches: 1.53.2;
XSH5: change function signature to `void *sbrk(intptr_t)'.

branches: 1.52.4;
Use standard system fchroot instead of emulation-specific copy.

Const poisoning and CHECK_ALT_CREAT fixes

remove compat_xxx dependencies where they don't belong

Defopt COMPAT_43

Defopt SYSVMSG, SYSVSEM and SYSVSHM.

Signal compat: sunos sigset_t conversions;
new sunos_sigvec() & sunos_sigpending()

defopt NFSSERVER

Include the NFS option header.

Make mman(2) functions args consistent (caddr_t -> void *)

ostat -> stat43

sys_getdirentries -> compat_12_sys_getdirentries from Juergen Hannken-Illjes.

branches: 1.41.4;
Use compat_12_sys_swapon().

now need sunos_sys_swapon() as ours is different.

branches: 1.39.2; 1.39.6;
NFSCLIENT -> NFS

branches: 1.38.2;
Modify poll(2) prototype.

Implement poll(2).

add obsolete stime(2)

Implement sunos_sys_execve(). The previous code simply called
sys_execve() without doing an alternate patch check, which was
incorrect. Bug pointed out by Krister Walfridsson <cato@df.lth.se>
on port-sparc@NetBSD.ORG.

Catch up with setre[ug]id() changes.

branches: 1.33.4;
Insert sunos_sys_fcntl().

Prefix names of system call implementation functions with `sys_'.

Start using sunos_sigvec().

Oops... NOARGS for compat_43_sigvec.

sigvec -> compat_43_sigvec.

Use compat_util.[ch]

Go with the flow; use `/emul/sunos' pseudo-root (from Matthew Green).
Note: sunos_stat() and sunos_lstat() were added too.

Added sunos_reboot().

- added struct emul to all emulations.
- removed all setup functions.
- added copyargs() functions where needed.

repair SYSV_* system calls

a few other things which work

sunos ptrace & poll emulation

fix sunos_mmap

new RCS ID format.

whoops

rename, new syscall interface, etc.

New RCS ID's, take two. they're more aesthecially pleasant, and use 'NetBSD'

update to match recent getdtablesize() change

backwards compat for a few things.

three changes i forgot, from Gordon Ross (gwr@lamp)

SunOS's RLIMIT_NOFILE is different: add sun_[gs]rlimit().

fix botch

do the syscall shuffle

first cut at a SUNOS_COMPAT sysconf() system call.

m68k/sparc sunos binary compatibility code, pulled down from magnum branch
for consumption by the m68k masses

branches: 1.8.2;
moved from arch/sparc/sunos to compat/sunos

new compat functions: sun_open, sun_auditsys, sun_setpgid, sun_uname
some from Markus.

update to kern/syscalls.master, for SYSVSEM & SYSVMSG

update to 4.4 way of doing syscall#0

use the standard {get,set}domainname stuff

Add a stub auditsys() system call that does nothing.
SunOS /sbin/fsck calls it..

various changes, suffice to say that 4.4 syscalls do not look like ours

Chris Torek's sparc port. Missing lots of things.
