Fix several issues with parsing the notes for ELF objects.
Badly formed ELF note may cause the caclulated pointer to the next note
to point both after the note region, that was checked in the code, but
also to point before the region, that was not checked [1]. Remember the
first note location in note0 and leap out if the note is not between
note0 and note_end.
In the similar way, badly formed note may cause infinite loop by
pointing next note into the same or previous note. Guard against this by
limiting amount of loop iterations by arbitrary choosen big number.
For clarity, check the calculated note alignment in each iteration.

NO_INQUIRY is wrong for this device. Alternatively, if it is right,
it is right for only a tiny fraction of these devices and this

In general, the kernel virtual address of the pml4 page table page that is
stored in the pmap is from the direct map region. The two exceptions have
been the kernel pmap and the swapper's pmap. These pmaps have used a
kernel virtual address established by pmap_bootstrap() for their shared
pml4 page table page. However, there is no reason not to use the direct
map for these pmaps as well.

Eliminate the recomputation of pcb_cr3 from cpu_set_upcall(). The

In nfs_request(), always exit using the nfsmout label once we're
definitely doing an NFSv2 or NFSv3 RPC, rather than sometimes doing
so and sometimes not. This makes it easier to add a DTrace return
probe at a single point in the function.
Fix a bug in the recent update to the Chelsio driver.
The tick routine was not being restarted in the init_locked routine
which could resulted in loss of carrier when updating the MTU.

- In bge_ifmedia_upd_locked() take advantrage of LIST_FOREACH().
- If boot verbose, print asicrev, chiprev and bus type on attach.
- For PCI Express devices:
1) Adjust max read request size to 4Kbytes
2) Turn on FIFO_LONG_BURST in RDMA during bge_blockinit()
Though 1) does not seem to have much to do with the poor TX performance
observed on PCI Express bge(4), 2) does fix the problem. [1]
- Nuke the RX CPU self-diag, which prevents working cards from working
(Linux tg3 does not have this diag neither does OpenBSD's bge(4)).

Expand the per-node access cache to cache permissions for multiple users.
The number of entries in the cache defaults to 8 but is easily changed in
nfsclient/nfs.h. When the cache is filled, the oldest cache entry is
evicted when space is needed.
I mirrored the changes to the NFSv[23] client in the NFSv4 client to fix
compile breakage. However, the NFSv4 client doesn't actually use the
access cache currently.

Just use default behaviour on tabstops when using too many columns.
It seems I didn't fix this issue before committing teken to the tree. My
initial idea was to somehow add an error mechanism to instruct the video
driver author to increase T_NUMCOL when using very big terminals. It
turns out we have platforms where we have gigantic consoles on systems
like the Apple PowerMac G5, which means we crash there right now.
Just ignore tabstops placed beyond column 160. Just force tabs to be
placed on each 8 columns.

Call the interface's if_ioctl from ifioctl(), if the protocol didn't
handle the ioctl. There are other paths that already call it, but this
allows for a non-interface socket (like AF_LOCAL which ifconfig now
uses) to use a broader class of interface ioctls.
Do not underflow the buffer and then report the problem. Check for the
condition before the buffer write.
Also, since buflen is unsigned, previous check was ignored.
