objects.
Programs such as sshd depend on two pointers to the same function being
equal in a given process. However, the current ia64 implementation
ensures that they're equal when both the pointers are instantiated in
the same ELF object. The attached patch ensures that they're equal
irrespective of where they're instantiated.

- Move UltraSPARC I and II (spitfire, blackbird, sapphire, sabre) specific
functions to spitfire.c, and add cheetah.c for UltraSPARC III specific
functions. Initially just cache flushing, but there are a few other
functions that will need to move here.
- Add an ipi handler for data cache flushing on UltraSPARC III.
- Use function pointers to select the right cache flushing functions based
on cpu_impl.
With this it is possible to boot single user from an mfs root on UltraSPARC
III systems, including spinning up secondary processors. There is currently
no support for the host to pci bridge, and no documentation for it is
publically available.

III+ cpus.

- Disable the "system tick" interrupt for UltraSPARC III. This avoids
an interrupt storm on startup since we're not prepared for these at
all. This feature has questionable use anyway.
- Clear tick on startup and then leave it alone.

routine, for example pthread_cond_timedwait().
Also extract upcall scheduling code from kse_reassign and create
a new function called thread_switchout to include these code.

careless users vulnerable to terminal control sequence attacks,
since they expect uudecode to just drop (or overwrite) a file in
the current directory. POSIX also says that the full pathname from
the input should be used when writing a file, which we only do if
the -s (shoot me in the foot) option is specified; therefore this
revision means that you now need to use -s for standard /dev/stdout
handling.

I have no further plans for mutilating this API at this point in
time, and will update the man-page to reflect current reality as
the next thing.

the devstat is for an "interior" GEOM node and register using the
name argument as a geom identity pointer. Do not put these devstat
structures on the list returned by the sysctl.
This gives us the ability to tell the two kinds of nodes apart and
leave the current "strictly physical" view of devstat intact without
modifications, yet be able to use devstat for both kinds of devices.
It also saves us bloating struct devstat with another 48 bytes of
space for the name. At least for now.

Add a mutex and protect the allocation and traversal of the list with it.
When we allocate a page for devstat use we drop the mutex and use
M_WAITOK this is not nice, but under the given circumstances the
best we can do.
In the sysctl handler for returning the devstat entries we do not want to
hold the mutex across copyout(9) calls, so we keep a very careful eye on
the devstat_generation count, and abandon with EBUSY if it changes under
our feet.
Specifically test for BIO_WRITE, rather than default non-read,non-deletes
as write. Make the default be DEVSTAT_NO_DATA.
Add atomic increments of the sequence[01] fields so applications using the
mmap'ed view stand a chance of detecting updates in progress.
