as "machdep.msgbuf". It's needed in case of using stripped kernels, where
normal dmesg (which has to use kvm) doesn't work.
The buffer is unwound, meaning that the data will be linear, possibly
with some leading NULLs.

object format of the executable being dumped. This is the first
step toward producing ELF core dumps in the proper format. I will
commit the code to generate the ELF core dumps Real Soon Now. In
the meantime, ELF executables won't dump core at all. That is
probably no less useful than dumping a.out-style core dumps as they
have done until now.

standard places ("/etc/objformat", ${OBJFORMAT}, argv) for an
indication of the user's preferred object file format. This
consolidates some code that was starting to be duplicated in more
and more places.
Use the new function in ldconfig.
Note: I don't think that gcc should use getobjformat(), even though
it could. The compiler should limit itself to functions that are
widespread, to ease porting and cross-compilation.

files. I have split the object format specific code into separate
source files. It's cleaner than it was before, but it's still
pretty crufty.
Don't cheat on your make world for this update. A lot of things
have to be rebuilt for it to work, including the compiler and all
of the profiled libraries.

Maintain a mapping from (iopaic number, int pin) tuple to irq number,
and use this when configuring devices and programming the ioapics.
Previous code assumed that irq number was equal to int pin number, and
that the ioapic number was 0.
Don't let an AP enter _cpu_switch before all local apics are initialized.

make could do that!

Normally the full 640x480 (768x576 PAL) image is grabbed. This ioctl
allows a smaller area from anywhere within the video image to be
grabbed, eg a 400x300 image from (50,10).

- moved definition of MACHINE_ARCH from cpu.h to parm.h as alpha.
- Added definitions of _MACHINE and _MACHINE_ARCH.
- Added hw.ispc98. The hw.ispc98 is 1 in PC98 kernel and is 0 in
IBM-PC kernel.

were to be rebooted after installing the 3.0 binaries without the
new kernel, the system is hosed.
The addition of this config file reserves the name of the config file
that the upgrade procedure uses. If an upgrade is to be performed on
a 2.2.5/6/7 system system for which a GENERIC kernel is inadequate,
this config file must be replace with a suitable one before performing
the upgrade.
On systems which report 'uname -r' as 3.0-CURRENT, the kernel build
is not performed and this file is ignored.
Add a sysctl 'machdep.cs_recv_delay' to specify how long to wait after
receiving a packet in order to check for a subsequent (back-to-back)
packet. The cs8900 has a very small receive buffer, so this helps avoid
overflows at the cost of some extra CPU overhead.
