Validate usec ranges in netbsd32___select50()

Later in the code selcommon() checks for proper timespec, check only
correct usec of timeval before type conversions.

Replace M_IOV and some malloc(9)s with kmem(9), and while there:
- Fix invalid free (M_TEMP vs M_IOV) in do_sys_recvmsg(), spotted by jakllsch@.
Also, same fix in osf1_sys_sendmsg_xopen().
- Fix at

Also, same fix in osf1_sys_sendmsg_xopen().
- Fix attempt to free non-allocated memory in error path in netbsd32___getfh30().
- Plug a memory leak in compat_43_netbsd32_orecvmsg().

- selcommon/pollcommon: drop redundant l argument.
- Use cached curlwp->l_fd, instead of p->p_fd.
- Inline selscan/pollscan.

Move the internal poll/select related API's to use timespec instead
of timeval (rides the uvm bump).

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

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.

ANSIfy most of the function definitions in sys/compat (but not ndis).
All by the magic of sed ...

Change all the NETBSD32PTR64(SCARG(uap, xxx))) to SCARG_P32(uap, xxx).

remove all the double (and triple) casts used to convert 32bit userspace

remove all the double (and triple) casts used to convert 32bit userspace
pointers to and from 64bit kernel pointers. Instead use the defines
NETBSD32PTR64(p32) to read a 32bit pointer and (the new) NETBSD32PTR32(p32,p64)
to write a 32bit pointer throughout.
The 32bit pointer is now a struct to enforce the above.
amd64 (with linux emul) and sparc64 will both compile (when the arch stuff
goes in soon), and amd64 still runs some i386 binaries.

Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.

merge ktrace-lwp.

Fix lossage I created with the 64 bit ino_t change.

Implement pselect(2) and pollts(2).

Make netbsd32_select() use selcommon() instead of a gross copy/paste of
the old sys_select() code.

Don't do the tsleep dance if timo is 0; simplify the code.

Merge the nathanw_sa branch.

In preparation for COMPAT_NETBSD32 on SH-5:

- The MD netbsd32_machdep.h header now defines the 32-bit pointer type
instead of using u_int32_t everywhere,
- The MD netbsd32_machdep.h header now

In preparation for COMPAT_NETBSD32 on SH-5:

- The MD netbsd32_machdep.h header now defines the 32-bit pointer type
instead of using u_int32_t everywhere,
- The MD netbsd32_machdep.h header now defines a macro (at least on
current implementations) which converts a 32-bit pointer to its 64-bit
equivalent,
- Change the MI code to utilise the above two items in all the right places,
- Implement netbsd32___sigaction_sigtramp().

Tested on Sparc64 by Matt Green.

have no special interpretations besides simple syscall args conversion.
