expensive than assigning NULL to ro.ro_rt and bzero of ro.ro_dst.

idx'th present CPU with pc_acpi_id equal to *acpi_id. If *acpi_id
does not match that processor's pc_acpi_id, return the value for
ProcId derived from the MADT in *acpi_id. If pc_acpi_id is 0xffffffff,
always override it with the value of *acpi_id. Finally, return
pc_cpuid in *cpu_id and use that as our primary key.
* Use pc_cpuid as our unique key because we know it is valid since
MD code set it. The values for ProcId in the ASL and MADT don't
match up on some machines (!), forcing us to fall back to ordered
probing in that case.
* Remove some #ifdef SMP since the refcount doesn't hurt performance
and will be needed for dynamic _CST objects. Only one #ifdef SMP
(for smp_rendezvous) remains.
* Hook up SMP in the compile flags in the Makefile.

KERNBUILDDIR by hand to achive the same effect.
I plan on referting this change after 5.2 is released, or sooner if
the issues with building releases are resolved and re@ approves.

transfer descriptors when a large request needs to be split into

take into account the offset of the chunk within the overall request.

for ipfw processing w/o an indication the packets were generated
by ipfw--and so should not be processed (this manifested itself
as a LOR.) The flag bit in the mbuf that was used to mark the
packets was not listed in M_COPYFLAGS so if a packet had a header
prepended (as done by IPsec) the flag was lost. Correct this by
defining a new M_PROTO6 flag and use it to mark packets that need
this processing.

Otherwise, stack junk would be left in sin_zero, which could

This should fix the wrong source address selection for connect() to

the MTRR Base/Mask registers. If you use the documented algorithm in the
systems programming guide, you'll get a GPF. The only thing that has
prevented this so far is that the bios pre-sets some MTRR entries which
we mis-interpreted sufficiently to fool the memcontrol interface into
thinking all the address space was taken and therefore rejected XFree86's
requests. However, not all bioses do this.. You get an insta-panic in
that case. Grrr. A better fix (dynamic mask) will happen by 5.3/5-stable
so that we automatically adapt to more than 40 physical bits.

very early (SI_SUB_TUNABLES - 1) and is responsible for setting mp_maxid.
cpu_mp_probe() is now called at SI_SUB_CPU and determines if SMP is
actually present and sets mp_ncpus and all_cpus. Splitting these up
allows an architecture to probe CPUs later than SI_SUB_TUNABLES by just
setting mp_maxid to MAXCPU in cpu_mp_setmaxid(). This could allow the
CPU probing code to live in a module, for example, since modules
sysinit's in modules cannot be invoked prior to SI_SUB_KLD. This is
needed to re-enable the ACPI module on i386.
- For the alpha SMP probing code, use LOCATE_PCS() instead of duplicating
its contents in a few places. Also, add a smp_cpu_enabled() function
to avoid duplicating some code. There is room for further code
reduction later since much of this code is also present in cpu_mp_start().
- All archs besides i386 still set mp_maxid to the same values they set it
to before this change. i386 now sets mp_maxid to MAXCPU.

different kernel to boot with kernel="NAME" would load the kernel and
loader.conf-selected modules from /boot/NAME, but it would not change
module_path. So, for instance, the automatically loaded acpi.ko would come
from /boot/kernel/acpi.ko, *always*.
Mind you, this happened for unassisted boot. If you interrupted, typed
"unload" and then "boot NAME", it would Do The Right Thing.
The source of the problem is the double initialization with beastie's
loader.rc. One would happen inside "start", and would load the kernel. The
next one would happen later in the loader.rc script, resetting module_path.
Because module_path is set to the Right Value by the functions in support.4th
that actually load the kernel, when beastie.4th proceeded to boot
module_path would remain wrong, as the kernel was already loaded.
This can be corrected by removing either initialization, and also by changing
the command used by beastie.4th from "boot" to "boot-conf", which makes sure
you use the right kernel and modules.
I chose to remove the second initialization, since this let you interrupt
(or confirm) boot before beastie even comes up. I avoid also doing the
boot-conf change because that would simply cause the kernel and modules to
be loaded twice (in fact, that was my original patch, until, in writing this
very commit message, I saw the error of my ways).
This commit changes the semantics of module loading when using the beastie
menu. Now it does what one would expect it to, but not what it was actually
doing, so something may break for unusual setups depending on broken
behavior. As our japanese friends so nicely put it, shikata ga nakatta. :-)

known samples of broken chipsets that needed mixed mode in the first place
are so broken (ie: locks up) that we can't use IO APIC mode at all and it
needs to be turned off in the bios. So, the MIXED_MODE penalty on the
good chipsets gained nothing.
