(eg: above 0xffc00000). Programs using /dev/kmem are implicitly racing
the kernel, and can get right up high in memory. I've been running
these for some time now, but with printfs. It's saved two panics at
least that I can remember.
md_regs being struct trapframe *. Do a npxsave() if needed and copy the
pcb rather than use the increasingly defunct savectx(). Copy %edi and
%ebp explicitly.

XXX npxproc could be declared in npx.h so the externs with smp fruit
are not needed.
Remove TF_REGP() macro and use. The original reason (address space
problems due to having UPAGES in mapped into user space) is gone. It
looks cleaner without it.
the patches in freefall:/home/dfr/ld.diffs to your ld sources and set
BINFORMAT to aoutkld when linking the kernel.
Library changes and userland utilities will appear in a later commit.

Stifle an annoying dma_start busy message for the sound cards.

. It makes cd9660 root f/s working again.
. It makes CD9660 a new-style option.
. It adds support to mount an ISO9660 multi-session CD-ROM as the root
filesystem (the last session actually, but that's what is expected
behaviour).
Sigh. The CDIOREADTOCENTRYS did a copyout() of its own, and thus has
been unusable for me for this work. Too bad it didn't simply stuff
the max 100 entries into the struct ioc_read_toc_entry, but relied on
a user supplied data buffer instead. :-( I now had to reinvent the
wheel, and created a CDIOREADTOCENTRY ioctl command that can be used
in a kernel context.
While doing this, i noticed the following bogosities in existing CD-ROM
drivers:
wcd: This driver is likely to be totally bogus when someone tries
two succeeding CDIOREADTOCENTRYS (or now CDIOREADTOCENTRY)
commands with requesting MSF format, since it apparently
operates on an internal table.
scd: This driver apparently returns just a single TOC entry only for
the CDIOREADTOCENTRYS command.
I have only been able to test the CDIOREADTOCENTRY command with the
cd(4) driver. I hereby request the respective maintainers of the
other CD-ROM drivers to verify my code for their driver. When it
comes to merging this CD-ROM multisession stuff into RELENG_2_2 i will
only consider drivers where i've got a confirmation that it actually
works.
simplifies some assumptions and stops some code compile problems.
This should fix the compile hiccup in PR#3491, but smp kernel profiling
isn't likely to be fixed by this.
- one-liners all become inline.
- multi-liners become functions.
- FAST_IPI defines go away.
re-worked APICIPI_BANDAID code.
- now refered to as DETECT_DEADLOCK.
- on by default.
Added [SR]RGBMASKs ioctl for byte swapping.

Generalized RGBMASK ioctls for general pixel

Clipping support added.
1.18 4/23/97 Clean up after failed CAP_SINGLEs where bt
interrupt isn't delivered, and fixed fixing
CAP_SINGLEs that for ODD_ONLY fields.

This code re-numbers PCI busses in the MP table to match PCI semantics
when the MP BIOS fails to do it properly.
