kernel will panic if an USB keyboard is plugged later.
Of course there will be a problem on a desktop machine with an USB attached
keyboard, but that cannot be fixed without access to such a machine..
CSR separately (and now from the correctly sized __fpregset_t). The
FP CSR is copied separately to avoid endianness/alignment issues.
Part of fix for PR port-mips/25942. Thanks to Christos Zoulas and
Klaus Klein for help with debugging this.
This areas is called the comm pages. It is used to provide fast access to
several data and functions.
The comm pages are mapped starting at 0xffff800 (address chosed so that
absolute branch can be used, so it can be accessed even when dynamic linking
is not ready). NetBSD has the user stack here, so we need to provide a
Darwin-specific stack setup routine which sets the top of the stack at
0xbfff0000.
This implementation is not complete but it does enough to get MacOS X.3
starting again (static binaries run, dynamic binaries still have an issue).
in the comm pages functions, we only implement bcopy, pthread_self and
memcpy.
TODO:
- clean up the powerpc specific code from MD parts
- for now we map only one page to avoid a crash, we want two pages.
- write all the comm functions.
Added membar_store, membar_load macros.
No need to set %asi _after_ alternate space use in corresponding functions.
Enable(unifdef) casa functions for __arch64__.
non-specific EOIs. This really shouldn't matter so much, but I'm guessing
there's a strange interaction with the PALcode (possibly related to the fact
that the PALcode itself may be sending an EOI itself on some systems).
I have tested this on a Multia, and it appears to work just fine without the
INITIALLY_{ENABLED,LEVEL_TRIGGERED}() stuff now, so I'm also removing that.
to all GENERIC-like kernel config files where SYSV* options were already

Fix lib/25897 and lib/25898.
off, or priority inversion can occur, which can lead to IPI deadlocks.
Leaves interrupts off for a bit longer, sadly, but with no noticeable
effects on the systems I tested on.
From YAMAMOTO Takashi.
* On systems where it's relevant (6600, kn300, kn8ae), check which PCI bus
hierarchy we're looking at.
* Consistently check PCI function numbers (important for quad-channel ATA
controllers).
* Check the channel number (important for ATA and multi-channel SCSI
controllers).
* Check logical unit numbers.
* Use strcasecmp() to check b->protocol; the case is different depending on
the firmware revision.
* Remove b->boot_dev_type check; it's unneeded.
* Remove extraneous unneeded variables.
Not only does this fix a few PRs and multiple long-standing bugs, but the
code is smaller too.

require that all bus tags have pointers to bus_space_read/write functions,
i.e. no run-time hunting for the first "upstream" implementation.
Since this changes the way bus tags should be constructed it makes sense
to do the same thing for the rest of the bus space methods.
So, now bus space tags are generally constructed by copying the parent's bus
tag and then overriding the methods that the bus driver needs to handle,
instead of starting with an empty bus tag and fiiling in only the fields needed.
This allows boot1() to change the sector number (of the boot partition)
that bootxx.S passes through to boot2().
This means that boot2() will find the correct partition when boot1()
reads /boot from the 'a' partition instead of the mbr boot partition.
This all happens when you update a system that used a small 'wd0h' partition
to boot a raid1 set to the new bootcode. Deleting /boot from the 'wd0h'
partition will make the new bootcode find /boot and the root filesystem
inside the raid set.
we're executing on; besides dealing with the bits not implemented in the
601's MSR it also removes the silent failure behaviour when passing
PSL_VEC set on a CPU not implementing it.
Also, fix those masks for the 4xx again.
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)

Use the real RF_PROTECTED_SECTORS define instead of a local magic number.

conditional on DIAGNOSTIC later, but there's no time-critical code
involved here.
Move the double fault stack away from the IPI stack. It's now shared
between CPUs, but that's not a big deal; double faults are fatal
and can't be recovered from.
