Diff reduction against bsdtar 2.8.3
MFC 206487 (kientzle):
If a file is specifically both included and excluded, then:
* It is not extracted (because it is excluded)
* If it's not present in the archive, then an error is
reported (because the file was requested and not found)
* If it is present in the archive, no error is reported.
Previously, this would always report an error because the
exclusion prevented the entry from matching the inclusion.
Also, tar is now more reluctant to report unmatched inclusions.
Previously, "tar x file1 'file*'" against an archive that contained a
single entry "file1" would match file1 and then report an error for
the second pattern because it wasn't matched. It now considers both
inclusions to be matched and reports no error.

MFC 202871 (kientzle):
If we can't stat a file, return the correct ARCHIVE_FAILED (this entry can't
be processed any further) and a suitable error string.
In particular, this improves the error-reporting when cpio -o is

MFC 202872 (kientzle):
Use a simpler memory-management strategy for the file objects.
Instead of trying to reference-count them and free them as soon

The new NFSv4 client handled NFSERR_GRACE as a fatal error
for the remove and rename operations. Some NFSv4 servers will
report NFSERR_GRACE for these operations. This patch changes
the behaviour of the client so that it handles NFSERR_GRACE
like NFSERR_DELAY for non-state related operations like
remove and rename. It also exempts the delegreturn operation
from handling within newnfs_request() for NFSERR_DELAY/NFSERR_GRACE
so that it can handle NFSERR_GRACE in the same manner as before.
This problem was resolved thanks to discussion with bfields at fieldses.org.
The problem was identified at the recent NFSv4 ineroperability
bakeathon.

PCIB_ALLOC_MSIX() may already fail on the first pass, f.e. when the PCI-PCI
bridge is blacklisted. In that case just return from pci_alloc_msix_method(),
otherwise we continue without a single MSI-X resource, causing subsequent
attempts to use the seemingly available resource to fail or when booting
verbose to NULL-dereference rle->start when trying to print the IRQ in
pci_alloc_msix_method().

- Current testing shows that (ab)using the JBC performance counter in bus
cycle mode as timecounter just works fine. My best guess is that a firmware
update has fixed this, so check at run-time whether it advances and use a
positive quality if it does. The latter will cause this timecounter to be
used instead of the tick counter based one, which just sucks for SMP.

UltraSPARC-IV CPUs seem to be affected by a not publicly documented
erratum causing them to trigger stray vector interrupts accompanied by a
state in which they even fault on locked TLB entries. Just retrying the
instruction in that case gets the CPU back on track though. OpenSolaris
also just ignores a certain number of stray vector interrupts.
While at it, implement the stray vector interrupt handling for SPARC64-VI
which use these for indicating uncorrectable errors in interrupt packets.

- For Cheetah- and Zeus-class CPUs don't flush all unlocked entries from
the TLBs in order to get rid of the user mappings but instead traverse
them an flush only the latter like we also do for the Spitfire-class.
Also flushing the unlocked kernel entries can cause instant faults which
when called from within cpu_switch() are handled with the scheduler lock
held which in turn can cause timeouts on the acquisition of the lock by
other CPUs. This was easily seen with a 16-core V890 but occasionally
also happened with 2-way machines.
While at it, move the SPARC64-V support code entirely to zeus.c. This
causes a little bit of duplication but is less confusing than partially
using Cheetah-class bits for these.
- For SPARC64-V ensure that 4-Mbyte page entries are stored in the 1024-
entry, 2-way set associative TLB.
- In {d,i}tlb_get_data_sun4u() turn off the interrupts in order to ensure
that ASI_{D,I}TLB_DATA_ACCESS_REG actually are read twice back-to-back.

that the following sequence:
ifconfig bge0 media 1000baseT mediaopt full-duplex
ifconfig bge0 media 100baseTX
results in 100baseTX full-duplex to be set or that:
ifconfig bge0 media autoselect mediaopt flowcontrol
ifconfig bge0 media 1000baseT mediaopt full-duplex
tries to set 1000baseT full-duplex with flowcontrol, which isn't suported
und thus fails while the following:
ifconfig re0 media 1000baseT mediaopt flowcontrol,full-duplex
ifconfig re0 media autoselect
just switches to autoselection without flowcontrol.
