comlock, I'd like to find and analyse these cases to see if they
really are valid.
So, throw in a lock here and wait for the (hopefully!) inevitable
complaints.
- As it turns out, MSI-X is broken for at least LSI SAS1068E when passed
through by VMware so blacklist their PCI-PCI bridge for MSI/MSI-X here.
Note that besides currently there not being a quirk type that disables
MSI-X only and there's no evidence that MSI doesn't work with the VMware
pass-through, it's really questionable whether MSI generally works in
that setup as VMware only mention three know working devices [1, p. 4].
Also not that this quirk entry currently doesn't affect the devices
emulated by VMware in any way as these don't claim support MSI/MSI-X to
begin with. [2]
While at it, make the PCI quirk table const and static.
- Remove some duplicated empty lines.
- Use DEVMETHOD_END.

- Remove all attempts to guess physical temperature using DiodeOffset.
There are too many reports that it varies wildly depending on motherboard.
Instead, if it is known to scale well and its offset is known from other
temperature sensors on board, the user may set "dev.amdtemp.0.sensor_offset"
tunable to compensate the difference. Document the caveats in amdtemp(4).
- Add a quirk for Socket AM2 Revision G processors. These processors are
known to have a different offset according to Linux k8temp driver.
- Warn about Family 10h Erratum 319. These processors have broken sensors.
- Report temperature in more logical orders under dev.amdtemp node. For
example, "dev.amdtemp.0.sensor0.core0" is now "dev.amdtemp.0.core0.sensor0".
- Replace K8, K10 and K11 with official processor names in amdtemp(4).
v_writecount. Keep the amount of the virtual address space used by
the mappings in the new vm_object un_pager.vnp.writemappings
counter. The vnode v_writecount is incremented when writemappings gets
non-zero value, and decremented when writemappings is returned to
zero.
Writeable shared vnode-backed mappings are accounted for in vm_mmap(),
and vm_map_insert() is instructed to set MAP_ENTRY_VN_WRITECNT flag on
the created map entry. During deferred map entry deallocation,
vm_map_process_deferred() checks for MAP_ENTRY_VN_WRITECOUNT and
decrements writemappings for the vm object.
Now, the writeable mount cannot be demoted to read-only while
writeable shared mappings of the vnodes from the mount point
exist. Also, execve(2) fails for such files with ETXTBUSY, as it
should be.

a new jail parameter node with the following parameters:
allow.mount.devfs:
allow mounting the devfs filesystem inside a jail
allow.mount.nullfs:
allow mounting the nullfs filesystem inside a jail
Both parameters are disabled by default (equals the behavior before
devfs and nullfs in jails). Administrators have to explicitly allow
mounting devfs and nullfs for each jail. The value "-1" of the
devfs_ruleset parameter is removed in favor of the new allow setting.

"panic in 8.3-PRERELEASE" on Feb. 22, 2012. This panic was caused
by use of a mix of tsleep() and msleep() calls on the same event
in the new NFS server DRC code. It did "mtx_unlock(); tsleep();"
in two places, which kib@ noted introduced a slight risk that the
wakeup() would occur before the tsleep(), resulting in a 10sec
delay before waking up. This patch fixes the problem by replacing
"mtx_unlock(); tsleep();" with mtx_sleep(..PDROP..). It also
changes a nfsmsleep() call to mtx_sleep() so that the code uses
mtx_sleep() consistently within the file.
