d4b259f874 With asbestos suit on, make the options indenting a little more consistant 
so that it doesn't screw up the alignment when commenting out an entry.
Also dequote two entries that do not need it.

9df9bf36b2 Dequote like on the i386 configs. Also remove some references to old 
i386 isa drivers that used to be order sensitive.  The probe order of
those drivers is now determined by a list in isa_compat.c and config
file order is totally irrelevant.

0676b04846 idev->id_irq is an interrupt MASK, not an interrupt number. 
Thus, we need to convert the mask to the number (by ffs()) when
writing back this value to the resource in save_resource().

7fb3641907 Keyboard allocation/deallocation fix. 
- Do not try to allocate a keyboard in pccnprobe() when probing the vt
  driver for the kernel console.  Rather, allocate a keyboard when
  initializing the vt driver in pccninit().
- Release the keyboard in pccnterm().
- Don't try to read from the keyboard, if it is not present.

934ebfaf1b Fill in tp->t_windowsize AFTER the call to (*linesw[tp->t_line].l_open)(), 
rather than BEFORE the call.  Otherwise the structure will be `zero'ed out
by l_open, which actually is ttyopen(), if !TS_OPEN.

582bbe6a3b No longer need to set B_ASYNC flag since BUF_KERNPROC now 
unconditionally sets the identity of the buffer.
 1999-06-29 15:57:40 +00:00

5f8ebc1b91 Hopefully fix the remaining glitches with the BUF_*() changes. This should 
(really this time) fix pageout to swap and a couple of clustering cases.

This simplifies BUF_KERNPROC() so that it unconditionally reassigns the
lock owner rather than testing B_ASYNC and having the caller decide when
to do the reassign.  At present this is required because some places use
B_CALL/b_iodone to free the buffers without B_ASYNC being set.  Also,
vfs_cluster.c explicitly calls BUF_KERNPROC() when attaching the buffers
rather than the parent walking the cluster_head tailq.

9a460a1161 Add some extra alpha_pal_imb()'s in overkill mode. This makes this PC164SX 
run quite reliably now.  I've explicitly tagged them as /* XXX overkill? */
although one does actually check for VM_PROT_EXECUTE.

cafc37474e Revert back to not using -DKERNEL - it exposes inlines etc. 
Zap symbols.raw and glue to make symbols.* - it's not used on the ELF-only

in-kernel linker symbol lookup.

0d5e2c5c4f When requesting an exclusive lock with LK_NOWAIT, do not panic 
if LK_RECURSIVE is not set, as we will simply return that the
lock is busy and not actually deadlock. This allows processes
to use polling locks against buffers that they may already
hold exclusively locked.

0b4727f459 The BUF_*() routines must be internally splbio() protected otherwise they 
can cause a biodone() from a disk interrupt to spin when the interrupt
code tries to grab the simplelock.  Masking BIO here means buftimelock
and/or lk->lk_interlock shouldn't be held when an interrupt tries to grab
them.
