allows this tool to compile again. Albeit, now to test a new malloc
implementation one has to install the new libc which may have bad
consequences (i.e. if the new malloc implementation were buggy).
Add logic to workaround malloc's current behaviour of returning an
invalid non-NULL pointer for 0 byte allocation requests; this prevents the
tool from coring during the NOPS loop.
Add $FreeBSD$ tags.
down, even if there are hung processes and the mount is non-
interruptible.
This works by having nfs_unmount call a new function nfs_nmcancelreqs()
in the FORCECLOSE case. It scans the list of outstanding requests
and marks as interrupted any requests belonging to the specified
mount. Then it waits up to 30 seconds for all requests to terminate.
A few other changes are necessary to support this:
- Unconditionally set a socket timeout so that even hard mounts
are guaranteed to occasionally check the R_SOFTTERM flag on
requests. For hard mounts this flag can only be set by
nfs_nmcancelreqs().
- Reject requests on a mount that is currently being unmounted.
- Never grant the receive lock to a request that has been cancelled.
This should also avoid an old problem where a forced NFS unmount
could cause a crash; it occurred when a VOP on an unlocked vnode
(usually VOP_GETATTR) was in progress at the time of the forced
unmount.
Add support for handling floating point disabled traps mostly in userland
for the simple single threaded case. Not yet enabled by default.
Implement __sparc_utrap_install as specified by the sparc abi.
This gives a bit of a sluggish console, but it prevents the console from
getting stuck if we poll too fast, as well as other badness on certain
machines.

for certain user pages, stores to kernel pages would not update the
affected cache lines, which would sometimes cause the wrong data to be
returned for loads from kernel pages. This was especially fatal when
the addresses affected held the kernel stack pointer, and a random
value was loaded into it.
Fix a harmless off by one error in a dcache_inval_phys call.
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.

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.
Some cleanup patches from Marco Molteni.
