panic( "xxxxx\n" );
to:
printf( "xxxxx\n" );
panic( "\n" );
For some as yet undetermined reason the argument to panic() is often NOT
printed, and the system sometimes hangs before reaching the panic printout.
So we hopefully at least print some useful info before the hang, as oppossed to
leaving the user clueless as to what has happened.
Remove "setdefs.h" and arrange to generate it automatically at
ELF kernel build time.
"gensetdefs.c" is a utility which scans a set of ELF object files
and outputs a line ``DEFINE_SET(name, length);'' for each linker
set that it finds. When generating an ELF kernel, this is run just
before the final link to generate "setdefs.h".
Remove the init_sets() function from "setdef0.c", and its call from
"machdep.c". Since "gensetdefs.c" calculates the length of each
set, it is no longer necessary in an ELF kernel to count the set
elements at kernel initialization time. Also remove "set_of_sets"
which was used for this purpose.
Link "setdef0" and "setdef1" into the kernel only if building for
ELF. Since init_sets() is no longer used, there is no need to link
them into an a.out kernel.
all uses of it with the equivalent calls to setbits().
This change incidentally eliminates a problem building ELF kernels
that was caused by SETBITS.

1) Adjust NFRAMES from 16 to 8 per 16k of memory.
2) Acknowledge interrupts to the card early in the interrupt
handler before processing the event that caused the interrupt.
This frees the card to process addtional events instead of
waiting for the driver to finish handling events.
3) Changed the initialization of the transmit buffers to be a
loop so that the number of buffers can be more easily changed.
4) Moved the code to take the adapter out of loop back mode to just
before we enable the receiver.
I also made the driver dynamically size its resource arrays at attach
time so that we can take full advantage of adapters with more than 16k
of memory.
Richard has some other changes he's working on to improve performance,
but this should get ee16 support working reliably again.

full implementation of the sate machine as described in RFC1661, and
provides support for plugging in various control protocols. I needed
this to provide PPP support for the BISDN project (right now).
Unfortunatley, while the existing API was almost up to the point, i
needed one minor API change in order to decouple the this-layer-
started and this-layer-finished actions from the respective Up and
Down events of the lower layer. This requires two additional lines in
the attach routines of all existing lower layer interface drivers that
are using syncPPP (shortcutting these actions and events). Apart from
this, i believe i didn't change the API of all this, so everything
should plug in without too many hassles. Please report if i broke
something in the existing drivers.
For a list of features (including new ones like dial-on-demand), and
things still to be done, please refer to the man page i'll commit asap.

- gcc assumes that %ecx and %edx are clobbered (due to calling
conventions), thus there is no need for saving/restoring those two
registers.
- %es is reset to default value by real_to_prot, thus there is no need
for saving/restorig that register.

When an ioctl command SW_XXXX is issued, scioctl() checks if the font
appropriate for the specified mode is already loaded. The check was
correctly done for 8 line and 16 line fonts, but not for 14 line font.
The symbols FONT_8, FONT_14 and FONT_16 were defined as numbers but
were sometimes treated as bit flags. They are now defined as bit
flags.
2) screen blinking (two fixes)
Removed a redundant call to timeout() in do_bell().
Don't let blink_screen() write to the video buffer if the screen is in
the graphics (UNKNOWN) mode.
3) screen saver timeout
The ioctl command CONS_BLANKTIME sets the screen saver's timeout. The
value of zero will disable the screen saver. If the screen saver is
currently running it should be stopped.
4) border color and destructive cursor (two fixes)
The border color and the cursor type can be changed via escape
sequences. But only VGA can change the border color and set the
cursor type to destructive (CHAR_CURSOR) in the current syscons.
scan_esc() failed to check this.

Remove TF_REGP() macro and use. The original reason (address space
