add support COMPAT_LINUX for aarch64

Do not uselessly include <sys/malloc.h>.

branches: 1.33.40; 1.33.58;
Include <sys/sched.h> before <sys/syscallargs.h> for cpuset_t.

branches: 1.32.2; 1.32.4;
Remove clause 3 and 4 from TNF licenses

branches: 1.31.6; 1.31.8; 1.31.10;
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: 1.30.4;
ANSIfy most of the function definitions in sys/compat (but not ndis).
All by the magic of sed ...

branches: 1.29.14; 1.29.16; 1.29.24;
Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.

branches: 1.28.2;
Merge newlock2 to head.

branches: 1.27.18; 1.27.48;
Merge the nathanw_sa branch.

add RCSIDs (including regeneration of files as appropriate)

branches: 1.25.24; 1.25.26;
Assign my copyright to TNF. Merge with others were appropriate.
Regen syscall files after script change.

Attempt to fix the mess.

Split compat/linux/linux_file.c into common and multi-architechture parts.

* Use sys___posix_{chown,fchown}() instead of sys_{chown,fchown}().
* Change reference from sys_posix_rename() to sys___posix_rename().

Fix the shared library versioning snafu caused by the recent changes
to the stat(2) family and msync(2). This uses a primitive function
versioning scheme.

This reverts the libc shared library major version from 13 to 12, and
adds a few new interfaces to bring us to libc version 12.20.

From Frank van der Linden <fvdl@NetBSD.ORG>.

Fix bogosity in mknod(2) translation.

check for st_nlink overflow

Add missing preparation of F_GETLK parameters in linux_sys_fcntl(); fixes PR
port-i386/4083 from Matthias Scheler <tron@lyssa.owl.de>, but vastly cleaned
up as previously suggested by myself.

branches: 1.17.4;
Use sys_posix_rename() instead of sys_rename() as it's the behaviour of the
native implementation.

printf -> kprintf, sprintf -> ksprintf

Update list of Linux syscalls and implement the ones that are likely to be
used and doable.

Prototyping changes.

Work around calling the NetBSD fcntl(F_{G,S}ETOWN) for now; it is too
restrictive to implement the Linux equivalent (and perhaps too restrictive
overall).

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

Make system calls conform to a standard prototype and bring those
prototypes into scope.

Fix some bugs & typing problems.

Add a hook for MD ioctl calls, plus a couple of more changes to make
svgalib binaries work on the i386

Rearrange #includes.

mkdir() has 2 arguments.. fixes PR 1248 (from Brad Spencer)

Fix totally bogus implementation of a few fcntl() calls. I think I'll go
live on a deserted island now..

Use compat_util.[ch].

* Changed to use generic ELF code from kern/exec_elf.c (which was taken
from the svr4 exec code plus the linux compat mods)
* Include file change
* Add multicast sockopts (from John Brezak)

Fix conversion of `type' and `whence' values in struct flock.

Added a few more system calls.
More consistent alternate root file semantics throughout.

Added Linux compat code.
