Fix a potential race in setting up the per-cpu pointer if the special
restore fails on return to user mode fails and we need to trap back
into the kernel to fault in more stack.
Remove debug code.
an efficient way for the kernel to bounce certain mundane traps back to
userland for handling there. A user trap handler returns directly to the
trapping user code, rather than going through the kernel again. Only a
handful of instructions are actually executed in kernel mode.
Implement sysarch(SPARC_UTRAP_INSTALL).
Add code to handle sharing of the user trap table across forks and unsharing
at exec.
This can be used to implement efficient tracking of floating point register
usage in userland, fe by a thread library, and to handle alignment fault
fixups and instruction emulation in userland, for which the code may need
to be different for 32bit and 64bit binaries.
something wrong with the kernel stack.
Add code to check the kernel stack pointer in various important places
and try hard not to go down in flames if its wrong.
- Move from msleep/wakeup to condvar.
- Return either zero or a positive errno value from a function.
Return additional result via references.
- Unify the typedef of callback functions.

a packed array so sizeof work. This broke RFMON mode and passing
up 802.11 packets.
The Linux emulation code was derived from the open source Linux driver to
maintain compatibility.
LEAP support is added, hints from Richard Johnson. I've verified this
locally with PC350v42510.img firmware. More bug fixing from Marco to
fix long passwords.
Change DELAYs in flash part of driver to FLASH_DELAY which uses tsleep
so it doesn't look like your system died during a flash update.
Install header files in /usr/include/dev/an
Cleanup some ifmedia bugs add "Home" key mode to ifmedia and ancontrol.
This way you can manage 2 keys a little easier. Map the home mode into
key 5. Enhance ifconfig to dump the various configured SSIDs. I use
a bunch of different ones and roam between them. Use the syntax similar
to the WEP keys to deal with setting difference SSIDs.
Bump up up the Card capabilities RID since they added 2 bytes to it
in the latest firmware. Thankfully we changed it from a terminal
failure so the card still worked but the driver whined.

they were right. Fix both kenter() and kremove() for SMP by ensuring that
the tlb is flushed on other cpu's. This will directly solve random-corruption
panic issues in -stable when it is MFC'd. Better to be safe then sorry, we
can optimize this later.

Maybe MFC: immediately on re's permission
socreate(), rather than getting it implicitly from the thread
argument.
o Make NFS cache the credential provided at mount-time, and use
the cached credential (nfsmount->nm_cred) when making calls to
socreate() on initially connecting, or reconnecting the socket.
This fixes bugs involving NFS over TCP and ipfw uid/gid rules, as well
as bugs involving NFS and mandatory access control implementations.

must have been inadvertently changed to '>'. This broke nfsm_adv()
in the case where the advancement count is equal to the amount of
data remaining in the current mbuf. Instead of moving the current
position N bytes forward, nfs_adv() could end up moving it back to
N bytes from the start of the mbuf data.
This should fix the client-side readdirplus problems that have been
reported since September.
In order of importance:
* Make ugen use updated frlengths.
* More tests for NULL pipes.
* Generate better error codes on bulk write.
* Error messages in general.
