miod pointed out that time_second should be compared to 1 not 0 in the
md resettodr() functions as it is initialised to 1.

Tested on aviion and luna88k.

stack from the main processor, instead of from the secondary processors
themselves. This used to work until recent churn in uvm require the kernel
lock to be taken, and cpu_configure() runs with the kernel lock held by the
boot processor.
Allocating the idle stack on the secondary processors themselves was choosen
early on, because there is no easy way, from the boot processor, to know the
assocation between physical cpu number (ci_cpuid) and logical cpu number
(the order they are initialized and reported in), especially on luna88k where
there is no way to get secondary processors parked by the prom.
Regression noticed by aoyama@. Verified to work on 2 and 4 cpu luna88k systems
and 2 cpu aviion systems.

- rename uiomove() to uiomovei() and update all its users.
- introduce uiomove(), which is similar to uiomovei() but with a size_t.
- rewrite uiomovei() as an uiomove() wrapper.

This should catch all the same bad cases, but be a little less aggravating
in circumstances where a prototype isn't necessary

PROT_NONE, PROT_READ, PROT_WRITE, and PROT_EXEC from mman.h.
PROT_MASK is introduced as the one true way of extracting those bits.
Remove UVM_ADV_* wrapper, using the standard names.

This makes it easier to remove components not required to do an install,
and subsequently add other desireable components ...
In snapshots (in various forks) for about a week.
Do some upgrades and installs, please.

CIRCLEQ_* is deprecated and not called in the tree. The other queue types
have *_END macros which were added for symmetry with CIRCLEQ_END. They are
defined as NULL. There's no reason to keep the other *_END macro calls.

- Always use either: ((x & RB_XXX) != 0) or ((x & RB_XXX) == 0) in boolean
context (mostly if (x), or x ? y : z)
- prom_halt() in alpha is confirmed to take int as boolean

rebooting a machine, like it is done in the hibernate case.
At least some USB host controller drivers rely on this to busy way instead
of sleeping. Avoid a panic on macppc with an uhci(4) cardbus plugged in.

Again remove slightly different comments to reduce diffs. These will be
re-added once boot() become MI and its specification is clearly re-defined.
OK miod@
|

RB_TIMEBAD is documented well enough that the comment is not needed. sparc64
does slightly different and its comment is left with XXX.

denormal results) with C code using softfloat to correctly round the inexact
results in the best possible way according to the current rounding mode.
No functional change intended, and this assembly code was surprisingly almost
non-buggy, as opposed to the precise exception code replaced a few weeks ago;
still an improvement as this replaces 900 lines of arcane assembly with 90
lines of understandable C code.

fault handling with a C wrapper around the softfloat code, as already done for
88110 kernels.
As a bonus, attempting to read or write FPU control registers but fcr62 and
fcr63 in userland will now correctly signal an illegal instruction, instead
of leaving the destination register unchanged and pretending nothing bad
happened.
Be sure to rm m88100_fp.d in your kernel compile directory after updating your
tree.

with softraid(4) disks.
softraid(4) is the last real consumer of the doshutdownhooks(9) API and it is
not trivial to convert its hook to a DVACT_POWERDOWN handler since the latter
does not allow to sleep.

"mainbus" device. this breaks when mpath is enabled because it
attaches before mainbus and therefore takes the head position.
have autoconf provide device_mainbus() which looks up mainbus_cd,
and use that instead.
discussed with deraadt who just wants mpath stuff to move forward
despite there being many ways to shine this particular turd.
