we don't use two-letters names already many years.
2) Make xterm-color just plain alias to xterm instead of unnecessary
reduplication of color capabilities already exist in xterm entry.
- Get the initial mode from the prom settings and don't clobber the mode
on open.
- Copy output into an internal ring buffer instead of accessing the tty
outq directly in the interrupt handler. This fixes a problem where
garbage would show up in the output stream.
- Reset the console port completely and reprogram all the parameters
before enabling it. This fixes seemingly random hangs on startup
when using a fast interrupt handler.
- Add minimal locking in place of spls.
- Remove dead code and minor cleanups.
available at module compile time. Do not #include the bogus
opt_kstack_pages.h at this point and instead refer to the variables that
are also exported via sysctl.
PS_STRINGS and USRSTACK is. This is necessary in order to decode a.out
core dumps. kern_proc.c was already referring to both of these values
but was missing the #include "opt_kstack_pages.h". Make the sysctl
variables visible so that certain kld modules can see how their parent
kernel was configured.
support this, we do have MI code that references it and is otherwise
unaware of an override. The alternative is to put knowledge in these
MI files about which platforms have the opt_kstack_pages.h option file.
It is more likely that other platforms will gain the ability to tune the
kstack size.
to userland in the signal handler that were not being iflled out before, but
should and can be.
This part of sendsig could be slightly refactored to use an MI interface, or
ideally, *sendsig*() would have an API change to accept a siginfo_t, which
would be filled out by an MI function in the level above sendsig, and said MI
function would make a small call into MD code to fill out the MD parts (some
of which may be bogus, such as the si_addr stuff in some places). This would
eventually make it possible for parts of the kernel sending signals to set up
a siginfo with meaningful information.

- add dependencies on opt_cpu.h and opt_kstack_pages.h to the linux module
Makefile in the i386 case. The latter is needed by an i386-only file, the
former by the i386 implementation of linux_sysvec.c (opt_cpu.h is used for
architecture-dependent options, so I added it only for i386, although this
file is also generated for the alpha).
- add a dependency on opt_kstack_pages.h to the pecoff module Makefile.
of pointers to strings. These two arrays were fixed to the same size, but one
had an implicit zeroed trailer element, which was unused because the size was
used up by the ones before said zeroed trailer element. So the unused limb was
chopped off the over-sized-but-not-over-sized array, and everyone lived happily
ever after.
if compiling with I686_CPU as a target. CPU_DISABLE_SSE will prevent
this from happening and will guarantee the code is not compiled in.
I am still not happy with this, but gcc is now generating code that uses
these instructions if you set CPUTYPE to p3/p4 or athlon-4/mp/xp or higher.
