uvm_km_alloc() (which allocates some virtual space and then
$size_of_mapping pages which it then enters) *then* pmap_kenter the
bus_space address that we wish to map, it's just a little bit stupid and
a waste of memory.
replace with uvm_km_valloc and ponies for everyone.

Also set it to 4, to accommodate for future UTF-8 support (rfc3629).

supported it doesn't do any harm), so put the KNOTE() in selwakeup() itself and
remove it from any occurences where both are used, except one for kqueue itself
and one in sys_pipe.c (where the selwakeup is under a PIPE_SEL flag).
Based on a diff from tedu.

long discussion with nicm, murmers of consent from tedu and miod, noone
else seems to care of kqueue is busted as long as it makes their sockets
move data fast... pretty sad.

This is needed for the addition of further suspend/resume actions.

return zero on success and nonzero on failure.
This commit only performs mechanical changes for the existing emulops to
always return zero.

first instead of trying to push data transfers forward. Also, ensure that
DONE interrupts are only un-masked when we are on the last sub-block, and
that otherwise we process based on RD_REQ and WR_REQ interrupts coming in.
Done with drahn and marex (starting from bizzare workarounds by marex
which we could not explain)
This appears to make Zaurus SD reads & writes completely reliable, even at
very low cpu speeds.

It is not needed to read MMC_STAT if DPRINTF is empty.

This patch also eliminates the bug causing any write to the card to hang the
whole controller (partly).

errnos. Note that the error strings are being ignored, since we long ago
decided to not spam the console, and there is no other nice way to use the
errors (without changing the ioctls to pass it back)
The errno is now useful, since we can pass b_error from failing IO up, and
the drive can decide how to use that

bus_space_alloc() as a bitmask of flags, and not a boolean controlling
cacheability; and make sure the three MI BUS_SPACE_MAP_xxx values documented
in the manual page are defined on all platforms as well.

The change was unrelated to v7 support, it was a cleanup item. For some reason
this breaks ksyms on zaurus. however zaurus uses the old loadfile that

For the possibility of sleeping, the first two flags are UVM_PLA_WAITOK
and UVM_PLA_NOWAIT. It is an error not to show intention, so assert that
one of the two is provided. Switch over every caller in the tree to
using the appropriate flag.

MD code would free resources that couldn't be freed until we were no
longer running in that processor. However, it's is unused on all
architectures since mikeb@'s tss changes on x86 earlier in the year.

- Split up run queues so that every cpu has one.
- Make setrunqueue choose the cpu where we want to make this process
runnable (this should be refined and less brutal in the future).
- When choosing the cpu where we want to run, make some kind of educated
guess where it will be best to run (very naive right now).
Other:
- Set operations for sets of cpus.
- load average calculations per cpu.
- sched_is_idle() -> curcpu_is_idle()

map to real hardware interrupt levels to have soft ipl values overlapping
hard ipl values without breaking spl asserts.

try to be smart for the address range, uvm_pglistalloc() is smart enough
nowadays.

APM_IOC_{SUSPEND,STANDBY}_REQ: This is to fix an issue with apm suspend
where a call to zzz suspended the machine immediately, not giving anyone
listening for apm events (other than apmd) a chance to deal with the
upcoming change. This hit X hard since the introduction of drm, since it
needs to have time to idle the 3d engine and otherwise get the device
into a recoverable state. Such things are needed until we support
modesetting in the kernel.
Now, instead of forcing a suspend, using ioctl sends out an event similar
to if you had put the lid down, giving all userland applications a
chance to reply.
tested by sthen@ and beck@, especial thanks to sthen for sitting there
while I tried to debug this remotely, I owe him beer.
