thorpej b27ebeeac1 Work-around the situation where the buffer cache is larger than
16M, thus eating up all candidate bounce pages, which are not allocated
until autoconfiguration runs, by deferring allocation of the buffer
cache pages until after autoconfiguration has run.

XXX This is safe because the i386 port doesn't read any disklabels
XXX during autoconfiguration.

fvdl be205fedc0 Define constants for the start and end VA of user page tables. 1997-12-07 21:30:11 +00:00
fvdl 4357e617d2 When getting a pagefault for a PT page, wire it. Normally we fault them in
ourselves, but this can still happen on a 386 in copyout & friends.

Fixes pmap_changebit panics seen on 386s. Thanks to Juergen Hannken-Illjes
for providing detailed info on bug occurances.

bouyer d45f82208d Add a cpu_setup() function to "struct cpu_nocpuid_nameclass" and
"struct cpu_cpuid_family", so that we can have a cpu_setup function per
known cpu type. For now use it only for cyrix 6x86 to enable suspend-on-halt
and implement cyrix's workaround to the "coma bug".

thorpej 46c5ad921d Add a workaround for buggy i486 PCI chipsets that have trouble with
memory-mapped device access (manifested by an apparent wedging of the
PCI bus):
- If cpu_class == CPUCLASS_486, disable memory-mapped PCI device access,
  leaving only i/o-mapped access enabled.
- Provide a patchable kernel variable (i486_pci_mem_enabled) and a kernel
  option (I486_PCI_MEM_ENABLED) to re-enable it.

works unless you have a strong stomach.

thorpej 4730a8cbec Bug fixes and cleanup from Chris Demetriou <cgd@pa.dec.com>:
- fix _C_LABEL so that it actually works.
- make __RENAME use _C_LABEL.
- fix __RENAME so that it expects an unquoted argument.
- fix __indr_reference and __warn_references so that they
  supply their own final semicolon.
- define __warn_references to nothing if not GNU C (required
  by the way it's used).

The __warn_references semicolon change has to be made
so that __warn_references can be defined into nothing.
(A ; all by itself isn't a great idea.)  The __indr_reference
change was made for consistency.
