6e39ad36a6 In pccngetc(), don't treat cn_tab->cn_dev as a valid device number until 
it's initialized.

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".

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.

0afda495f5 Do the Pentium bug fix differently. Put the IDT in a read-only page and check 
for a write fault on the illegal instruction descriptor.  Don't ask why this
works unless you have a strong stomach.

6a310175c6 Some general cleanup: 
* Call gdt_init() earlier on.
* Don't bother to check for TSS and LDT descriptors in verr_gdt().
* Nuke the sti special case for trace and breakpoint traps.
* Move some variable declarations into more appropriate locations.

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.

90e33ee203 When using XMS, use the XMS size returned by the BIOS only if the other 
methods to detect extended memory didn't work well.
