same as on bootrap processor

my x301 and t420 run out of archfiles with *acpi= while trying to add
hdacmd from audiohda.

on 82579LM, the phy status is inaccessible without
a cable plugged, so we wait and retry phyprobe() once
the link status changes.

timeout, timeout in blocked state, fix essid seprint race
- add some milisecond timestamps to the status change debug printing
- flush the packets in the queue on deassoc to avoid processing old pae
packets on next association.
- make roaming timeout shorter (60 -> 20 seconds)
- automatically timeout and restart wpa/pae blocked state
- fix printing race when essid gets changed underneath seprint

from openbsd driver, it seems the Centrino Advanced-N 6030 and 6235
cards share the same device revision as the 6205 (Type6005). Also
changing the device revision field from 4 to 5 bits.

- drivers enable short preamble and sort timeslot depending
on the ap beacon capinfo field (bss->cap)
- wifi sets short preamble bit in capinfo on association request
- wifi sets short timeslot bit when ap advertized it in beacon

given that the igfx driver doesnt provide any acceleration functions
and drawing is usually faster with double buffering as it eleminates
reads over the pci bus, enable softscreen by default.

on 386 kernel, each processor has its own pdb where the primary
pdb for kernel mappings is on cpu0 and other cpu's lazily pull
pdb entries from cpu0 when they fault in vmapsync().
so we have to edit the table tables in the pdb of cpu0 and not
the current processor.

on some modern machines like the x250, the bios arranges the mtrr's
and the framebuffer membar in a way that doesnt allow us to mark
the framebuffer pages as write combining, leading to slow graphics.
since the pentium III, the processor interprets the page table bit
combinations of the WT, CD and bit7 bits as an index into the
page attribute table (PAT).
to not change the semantics of the WT and CD bits, we preserve
the bit patterns 0-3 and use the last entry 7 for write combining.
(done in mmuinit() for each core).
the new patwc() function takes virtual address range and changes
the page table marking the range as write combining. no attempt
is made on invalidating tlb's. doesnt matter in our case as the
following mtrr() call in screen.c does it for us.

acpimem routines
get rid of _INI and _REG method calls, this is not full acpi environment
anyway and all we really want todo at kernel boot time is figuring out
the interrupt routing. aux/acpi can try to enable more stuff if it needs
to later when battery status desired.
dont snoop memory space regions in amlmapio(), this is just wrong as
amlmapio() is *lazily* mapping regions as they are accessed, so the
range table would never be really complete. instead, we provide generic
access to the physical address space, excluding kernel and user memory
with acpimem file.

the first time rtl8169link is called (from rtl8169pnp), the link isn't up, so
setting edev->mbps based on Phystatus register is skipped. edev->mbps is then
still set at the default 100, and that ends up being what devether uses.
this is why some rtl8169 cards are misprinted as 100Mbps in kmesg.
later, after rtl8169link is called again from rtl8169interrupt, the link is up
and edev->mbps is set to the correct value (as shown by e.g. /net/ether0/stats).
so instead, set speed regardless of link status.

http://www.9legacy.org/9legacy/patch/pc-ether82563-i210.diff (thanks k0ga)
This patch is only an adaptation for 9front of the patch located in
http://www.9legacy.org/9legacy/patch/pc-ether82563-i210.diff. The
major difference is that this patch ignores errors in checksum of
eeprom, because in my system the checksum was wrong. After 3 months,
I didn't have problems, and I think the patch can be used. although
it has some things that need to be fixed. If the link is inactive
when the system boots then it will remain inactive forever.

access to the axi segment hangs the machine when the fpga
is not programmed yet. to prevent access, we introduce a
new SG_FAULT flag, that when set on the Segment.type or
Physseg.attr, causes the fault handler to immidiately
return with an error (as if the segment would not be mapped).
during programming, we temporarily set the SG_FAULT flag
on the axi physseg, flush all processes tlb's that have
the segment mapped and when programming is done, we clear
the flag again.

this code was if(0) for a long time due to wrong parentesis,
fixed parentesis cause print spam on some machines making them
unusage (kenji okomoto). removing the check alltogether.

apparently, this causes some quadcore ramnode vm to hang on boot,
even tho all cores successfully started up and are operational.
i suspect some side effect from timersinit()... this would also
mean *notsc= would break it (syncclock() would continue)...
its unclear.
i'm reverting this for now until the problem is better understood.

thunderbirdsarego
when testing in qemu, launching each ap became slower and slower
because all the ap's where spinning in syncclock() waiting for
cpu0 to update its mach0->tscticks, which happens only much later
after all cpu's have been started up.
now we wait for each cpu to do its timer callibration and
manually update our tscticks while we wait and each cpu will
not spin but halt while waiting for active.thunderbirdsarego.
this reduces the system load and noise for timer callibration
and makes the mp startup linear with regard to the number of
cores.

introduce cpushutdown() function that does the common
operation of initiating shutdown, returning once all
cpu's got the message and are about to shutdown. this
avoids duplicated code which isnt really machine specific.
automatic reboot on panic only when *debug= is not set
and the machine is a cpu server or has no display,
otherwise just hang.

if beacon/proble contains both wpa information element and rsne, the rsne wins.

introduce wificfg() function to convert ether->opt[] strings
to wifictl messages, which needs quoting for the value. so
etherX=type=iwl essid='something with spaces' works.
