ae8e1d08d7 This patch clears the way for removing a number of tty related
fields in struct cdevsw:

        d_stop          moved to struct tty.
        d_reset         already unused.
        d_devtotty      linkage now provided by dev_t->si_tty.

These fields will be removed from struct cdevsw together with
d_params and d_maxio Real Soon Now.

The changes in this patch consist of:

        initialize dev->si_tty in *_open()
        initialize tty->t_stop
        remove devtotty functions
        rename ttpoll to ttypoll
        a few adjustments to these changes in the generic code
        a bump of __FreeBSD_version
        add a couple of FreeBSD tags

4be2eb8c49 I got tired of seeing all the cdevsw[major(foo)] all over the place.
Made a new (inline) function devsw(dev_t dev) and substituted it.

Changed to the BDEV variant to this format as well: bdevsw(dev_t dev)

DEVFS will eventually benefit from this change too.

f711d546d2 Suser() simplification:
1:
  s/suser/suser_xxx/

2:
  Add new function: suser(struct proc *), prototyped in <sys/proc.h>.

3:
  s/suser_xxx(\([a-zA-Z0-9_]*\)->p_ucred, \&\1->p_acflag)/suser(\1)/

The remaining suser_xxx() calls will be scrutinized and dealt with
later.

There may be some unneeded #include <sys/cred.h>, but they are left
as an exercise for Bruce.

More changes to the suser() API will come along with the "jail" code.

8e203b83a7 Undo #undef KERNEL hack for vnode.h to avoid vnode_if.h.
XXX It probably makes sense to have a flag for bsd.kern.mk to avoid these
    rules.
XXX IO_NDELAY seems to be the main reason for it, when used in a cdevsw
    read or write "flag" context.  Perhaps a redundant declaration
    somewhere like sys/conf.h might help remove the need for vnode.h in
    these device drivers in the first place.

ecbb00a262 This commit fixes various 64bit portability problems required for
FreeBSD/alpha.  The most significant item is to change the command
argument to ioctl functions from int to u_long.  This change brings us
inline with various other BSD versions.  Driver writers may like to
use (__FreeBSD_version == 300003) to detect this change.

The prototype FreeBSD/alpha machdep will follow in a couple of days
time.

227ee8a188 Eradicate the variable "time" from the kernel, using various measures.
"time" wasn't a atomic variable, so splfoo() protection were needed
around any access to it, unless you just wanted the seconds part.

Most uses of time.tv_sec now uses the new variable time_second instead.

gettime() changed to getmicrotime(0.

Remove a couple of unneeded splfoo() protections, the new getmicrotime()
is atomic, (until Bruce sets a breakpoint in it).

A couple of places needed random data, so use read_random() instead
of mucking about with time which isn't random.

Add a new nfs_curusec() function.

Mark a couple of bogosities involving the now disappeard time variable.

Update ffs_update() to avoid the weird "== &time" checks, by fixing the
one remaining call that passwd &time as args.

Change profiling in ncr.c to use ticks instead of time.  Resolution is
the same.

Add new function "tvtohz()" to avoid the bogus "splfoo(), add time, call
hzto() which subtracts time" sequences.

a4daaa09f2 Implement the spirit but not the letter of Terrys hot-char patch.
The differences Terrys patch and this patch are:
 * Remove a lot of un-needed comments.
 * Don't put l_hotchar at the front of stuct linesw, there is no need to.
 * Use the #defines for the hotchar in the SLIP and PPP line disciplines

42d263adde Don't test for conflicting combinations of PPP_FILTER/BPFILTER here.
Testing in if_ppp.c is good enough.

Added comments about bogus #includes and #defines.

Removed unused #includes.

Don't depend on gcc's misfeature of rewriting short args in old-style
function definitions to match wrong prototypes.  I just changed the
function definition to match the prototype, since this is easy to
verify automatically (it causes no changes in the object code), but
it breaks K&R1 support and doesn't fix the pessimal type.

2d4b190bc5 Update kernel parts of pppd from 2.2.0 to 2.3.0. I've yet to look at the
2.3.0 -> 2.3.1 changes, but I seem to recall that there are certain
"issues" with 2.3.1 (I'm not sure if it's just pppd or the whole lot, I
am not quite that far).  The present pppd seems to work with it just fine
for the time being.

Among the changes are that zlib (aka LZ77 aka deflate aka gzip) compression
is implemented as well as the original compress(1) LZW style.

3bb3b0463e Fix this damn mbuf with a negative m_len. It turns
out to be a problem with VJ header compression.
davidg spotted this in usr.sbin/ppp/slcompress.c
a while ago, but I believe gave the wrong reasons -
it's too easy to reproduce !  The only scenario that
I've been able to reproduce the problem under is when
m_len is *exactly* 40 !  So go figure !

443e72b45a Protect against garbage mbufs in pppstart.
Remove previous hack in pppfcs().

This is still not the correct solution.  We shouldn't
have any incorrect mbufs.  This patch does however make
pppd/natd work (rather than jamming the interface).

a353ca89cd Bruce mentioned to me that Paul Traina had noticed that the ppp_tty
interrupt mask hackery wasn't happening when being modloaded via the
if_ppp lkm.  It seems that the lkm system doesn't particularly like having
two sets of load/unload/etc routines. :-]  This really should be fixed
by having a seperate if_ppp and ppp_tty lkm, but that requires that ppp_tty
is loaded after if_ppp, and needs to be able to link with symbols in
if_ppp.  This gets messy, it is a better task for the in-kernel linker.
(if_ppp is generic, ppp_tty is a tty-specific bottom end for if_ppp, it's
 not _too_ hard to have another "provider" (such as a hdlc sync card)
 connected to if_ppp)
