allocated slabs and bucket caches for free items. It will not go ask the vm
for pages. This differs from M_NOWAIT in that it not only doesn't block, it
doesn't even ask.
- Add a new zcreate option ZONE_VM, that sets the BUCKETCACHE zflag. This
tells uma that it should only allocate buckets out of the bucket cache, and
not from the VM. It does this by using the M_NOVM option to zalloc when
getting a new bucket. This is so that the VM doesn't recursively enter
itself while trying to allocate buckets for vm_map_entry zones. If there
are already allocated buckets when we get here we'll still use them but
otherwise we'll skip it.
- Use the ZONE_VM flag on vm map entries and pv entries on x86.

What really should be done is route the probe through
device_probe_and_attach bit this is one of those ICBBATIASS (I can't be
bothered as there is a simpler solution). The user can easily replug the
device after kldloading a new device driver.
'make load' if an object dir was, like it is used in /sys/modules. I.e.
cd /sys/modules/umass
make obj
make
make load
works again without having to install the module.
If no objdir was used the module in the current directory is used.
magic numbers. Use stxa_sync instead of stxa; membar #Sync; to ensure
that no instruction is placed between the two. This can cause random
corruption even though interrupts are already disabled.
Fixed pow(x, y) when x is very close to -1.0 and y is a very large odd
integer. E.g., pow(-1.0 - pow(2.0, -52.0), 1.0 + pow(2.0, 52.0)) was
0.0 instead of being very close to -exp(1.0).

Apply the same patch although it is just cosmetic because odd integers
large enough to cause the problem are too large to be precisely represented
as floats.

"snapend - l" underflows; this fixes a buffer overflow with malformed
NFS packets, and may fix other buffer overflows with malformed packets.

Since they were never documented and have never appeared in a FreeBSD
release, no repo-copy of the header is done. This removes namespace
pollution from <time.h>.
path... after we've talked to any RADIUS servers involved, so that we
haven't touched the data before it gets to the server.
Make it clearer in the code that this compensation is done by setting
a flag to a value of zero, a flag which rfc2759 says *MUST* be zero.
While we're here, don't bother passing the peer challenge into
radius_Authenticate(). It's already part of the key we're passing in
(this becomes obvious now that I've structured that data...).
This ``fix'' doesn't help to authenticate Win98/WinME users in my test
environment as ports/net/freeradius seems to ignore the flag
completely anyway, but it may help with other RADIUS servers.
o Move pmap_pageable() outside of Giant in vm_fault_unwire().
(pmap_pageable() is a no-op on all supported architectures.)
o Remove the acquisition and release of Giant from mlock().
CAM_QUIRK_HILUN devices we loop thru 32bits of lun. Oops.
Switch to using USEC_DELAY rather than USEC_SLEEP at isp_reset time.
Try to paper around a defect in clients that don't correctly registers
themeselves with the fabric nameserver.
Minor updates for Mirapoint support- they still use code that is not
HANDLE_LOOPSTATE_IN_OUTER_LAYERS, and, surprise surprise, this old
stuff had some bugs in it.
Clean up some target mode stuff.

topology, speed, loopid, WWPN/WWNN, etc.
Beef up target mode. Add isp_handle_platform_notify_scsi and
isp_handle_platform_notify_fc platform handlers to handle immediate
notifies (isp_handle_platform_notify_scsi is still stubbed out).
In implementation of isp_handle_platform_notify_fc, for IN_ABORT_TASK,
peel off a pending XPT_IMMED_NOTIFY and call xpt_done on it and hope
that somebody upstream is listening.
Make sure on final CTIO2s that we set residual correctly. These are
absolutely crucial. Make sure we set relative offset for each CTIO2
based upon bytes we've already xferred. This is what the private
adjunct datat to the original ATIO is. Note state of command so
we can figure out where to find it if we get an ABORT from the firmware.
Make sure we *always* set CAM_TAG_ACTION_VALID for ATIO2s. Make sure
we keep track of the original lun.
If se sent status (or we're otherwise done with the command), don't
forget to free the adjunct structure.
