cgd a2c213c028 fix code so that a 'generic' OFW kernel (which only uses OFW drivers)
will again compile.  This code needs a bunch of cleanup, and the
"generic OFW kernel" code should probably be split into a different
directory than the code which implements the interface to OFW.

thorpej 6626878e7b It is no longer necessary for pmap_pinit() and pmap_release() to be
pmap interface functions, as NetBSD no longer uses statically allocated
pmaps (except for the kernel pmap, which is special-cased anyhow).

cgd 2fb206b0cf clean up, get it closer to compiling. (Note that this change includes
a change marked XXX, where gcc -Wall pointed out a bit of the original
code that looked wrong.  The jury's still out on whether or not it was
really wrong, but it looked _very_ suspicious.)

cgd 72797e4632 Import sys/arch/arm32/{shark,ofw} bits of the Digital Network Appliance
Reference Design NetBSD source code, obtained from the pages under
http://www.research.digital.com/SRC/iag .  Some of this code (badly)
needs to be cleaned up, and as-is it doesn't compile.  However, getting
it in the tree is a start.

mark c1a332e5f7 Use a separate variable to indicate whether the fault is from USR mode
or not rather than orring in a USER bit into the fault code variable.
This simplifies the fault switch statement and some of the addition
checks that are made of the fault code.
Move the printing of data abort information out into a separate function
rather then duplicating a lot of similar printf() statements.
Removed the fault_code variables from the prefetch abort handler as it
is not actually used for anything.

mark 7c867905c5 Major overhaul of pagetable handing.
Page tables no longer occupy space in the processes vm_map. This
  means that page tables can now be allocated from pmap_enter() when the
  first entry is made in the page table rather than relying on taking
  a section fault and faulting in a page table. This also lowers
  the overheads in creating and deleting page tables and simplfies
  cpu_fork().
  A result of this change is that problems with mapping zero page and
  an associated pagetable when execing from a shared vm_map disappear
  fixing PR5178.

types large enough to hold any pointer.

mark 7782adb98e Use r12 as a temporary register in setrunqueue() and remrunqueue() as it
does not need to be preserved across function calls. This means the use
of r4 can be eliminated thus saving a stack push and pop for r4.

Remove a lurking spltty() just before a panic in the prefetch abort
handler.
1998-04-19 23:25:49 +00:00
mark 05a669badb General file cleanup. Grouped all the un-handled fault cases together
to share one panic string. Removed a number of postmortem() calls.
Use verbose_faults variable to dictate the printing of fault information.
In several address validation checks, reorder the conditions for more
optimial checking.

mark 464caff246 Since the kshell stuff is no longer ever built into the kernel,
the last possible hooks having been removed from rpc_machdep.c
and its use has been deprecated for a long long time lets finally
axe it.

howto to dictate what operations to perform.
Removed support for calling the deprecated kshell stuff.
Cleaned up a few bits of dead code and renamed rpc_sa110_kickstart() to
rpc_sa110_cc_setup().

as the first argument (currently unused).

tv b21bfbde11 Add -Wno-main conditional on compiler being gcc 2.8 or egcs. (This adds
a HAVE_GCC28 check-variable that can now be used to add other gcc-2.8
flags in cases where they may be useful, or to remove gcc 2.7.2 "bug
workaround" flags.)
