than losing, do what Windows does: just request the maximum size, and allow a
shorter response. Obsoletes the need for UQ_NO_STRINGS, and therefore these
"quirks" are removed.
just have to take an interrupt for each sector.
Tested with one laptop disk (which normally runs in DMA mode and was forced
to single-sector transfers) and 3 CF cards. Increases the performance of
the CF cards substantially (760KB/s->1240KB/s in one case, 410KB/s->750KB/s
in the other two cases).
- pfsync (due to protocol # assignment issues)
- carp (not really a PF portion, but thought important to mention)
- PF and ALTQ are mutually-exclusive. this will be sorted out when
kjc@csl.sony.co.jp updates ALTQ and PF (and API inbetween)

torture-test is very welcomed.
my ALi-based drive enclosure (it works now, rather than failing to attach).
Also seems to work with a GL811-based enclosure and an ASUS enclosure with a
CD-RW, on both Intel and NEC controllers.
Note: The ALi enclosure is currently very SLOW, due to some issue with taking
too long to notice that the QTD is complete. This requires more investigation.
newer machines (iBook G4), it is in pseudo-hid (without typo), and there
are no `adb-kbd-ihandle or `usb-kbd-ihandles methods. In that situation,
just try to attach anything we can.
This patch fixes spurious inputs on iBook G4.
property of "/chosen" node in OF tree. On newer machines (e.g: iBook G4),
this property does not exist. We look for the node "mpic" as a second attempt
after a failure in /chosen.
This makes the iBook G4 keyboard almost usable (there are still some spurious
inputs on system startupi)
doing copy-on-write.
- Change VFS_SNAPSHOT() to return the snapshot vnode locked.
- Make the IO path for copy-on-write and snapshot-read more lightweight.
Avoids deadlocks where vn_rdwr(...READ...) has a shared lock and needs
to copy-on-write.
Avoids deadlocks/panics where to clean pages the copy-on-write needs
to allocate pages for its VOP_PUTPAGES().

overloading "usec". The counter isn't counting micro-seconds, and using
the same variable to mean two different things is false economy: with
this change, the compiled object is 72 bytes smaller on i386, and the
code is easier to understand, to boot.
