script mode like the MRI(Microtec Research Inc.) "librarian" program.
Originally this option is provided by Binutils ar(1) to ease the
transition for developers who are used to writing "librarian" scripts.
We added this option to BSD ar(1) because:
1. Further improve the compatibility with Binutils ar(1).
2. There are still a few software using this -M option. (at least one
in our ports collection)

initialize the vattr structure in VOP_GETATTR() with VATTR_NULL(),
vattr_null() or by zeroing it. Remove these to allow preinitialization
of fields work in vn_stat(). This is needed to get birthtime initialized
correctly.

VOP_GETATTR() call in vn_stat(). Thus if a file system doesn't
initialize those fields in VOP_GETATTR() they will have a sane default
value.

Reverse the direction of pmap_promote_pde()'s traversal over the specified
page table page. The direction of the traversal can matter if
pmap_promote_pde() has to remove write access (PG_RW) from a PTE that
hasn't been modified (PG_M). In general, if there are two or more such
PTEs to choose among, it is better to write protect the one nearer the
high end of the page table page rather than the low end. This is because
most programs access memory in an ascending direction. The net result of
this change is a sometimes significant reduction in the number of failed
promotion attempts and the number of pages that are write protected by
pmap_promote_pde().
MFamd64 SVN rev 179777 CVS rev 1.621
Tweak the promotion test in pmap_promote_pde(). Specifically, test PG_A
before PG_M. This sometimes prevents unnecessary removal of write access
from a PTE. Overall, the net result is fewer demotions and promotion
failures.

be compiled with "only" -mcpu=v9 for reference and testing purposes.

viewed as an anti-foot-shooting measure and has no impact on normal

they point to the very same device. This should make loader usable on
some (all?) PowerMacs, where "/chosen/stdout" is disconneted from the
"screen" by the OF init process by default, except when user actually
has requested interaction with OF by holding ALT-CMD-O-F. Along with
rev 183168 this should provide a way to build bootable FreeBSD/ppc
installation or live CD that works OOB. Also, it should bring PowerMac
experience closer to that on other arches.

kib@ and I have decided we will MFC the bpf(4)/snp(4) fixes after we've
released 7.1. Make sure the code in HEAD doesn't refer to a flag we
don't need anyway.
snp(4) in the MPSAFE TTY P4 branch already works, but still needs some
polishing before it can be integrated to SVN.
this also can be happened if we pull the USN stick out forcibly.
Currently the ZyDAS driver uses tsleep() when it try to query a read
command to the device and it'd make a timeout if the device doesn't
response within about 1 sec.
In a case of that the USB stick is gone by hand and the driver's
scanning with changing the channel numbers, the thread which is sleeping
until a command requested is responded can be waked up after all
detaching routines finished that means the zyd softc already freed.
Tring to touch the softc freed by the wakeup thread makes a panic.
So make sure that all sleeping threads should be waken up before the
detach is completed and any other new requests to the device should be
prevented.
