2f832df90c Do proc0's TSS and LDT initialization at the end of configure() (i.e. 
once the FPU has been attached).

8371eb7a88 Clean up the BIOS disk matching code a bit (better naming, one structure 
and sysctl to export to userland). Also, only use total number of sectors
given in the extended parameters if the physical chs geometry is
marked invalid. Hopefully fixes a problem where BIOSs would not correctly
fill in this field.

bdb770bc34 Create a list of native disks too, and make it retrievable. It contains 
all matching BIOS disks per entry, so that we have complete match info.
Enable the matching code.

5db52a7a6b Add some fields to the already defined, but unused, bootinfo structure 
for BIOS geometry. Define CPU_BIOS_GEOM sysctl value in cpu.h.

49c62c4336 Changes to support fork_kthread(): 
- cpu_set_kpc() now takes void *arg third argument, passed to the
  entry point.
- cpu_fork() allows parent to be non-curproc iff parent is proc0.
  When forking non-curproc, assume its state has already been saved.
- Adjust various pieces of machine-dependent code to account of all of this.

d374462dfc Move the code that does the deferred (post-autoconfiguration) buffer 
cache allocation to its own function, and call it at the end of configure().

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".

c15f6d921f Changes for NKPDE calculation from cgd. 
- New variables: biosextmem, biosbasemem, nkpde
- Above can be set by using the options BIOSEXTMEM, BIOSBASEMEM,
  and NKPDE respectively (EXTMEM_SIZE is now called BIOSEXTMEM).
  When preset this way, they won't be filled in / calculated.
- Readable by sysctl using machdep.nkpde, machdep.biosbasemem
  and machdep.biosextmem.
- nkpde is calculated as:

	min(NKPDE_MAX, NKPDE_BASE + (biosextmem >> 10) * NKPDE_SCALE)

  Where NKPDE_MAX is 31, NKPDE_BASE is 4, NKPDE_SCALE = 1.

72805df917 Various changes from John Kohl and me: 
Map kernel stacks only at unique addresses.
Use one TSS per process.
Add sysarch calls for modifying IOPL and the I/O permission bitmap.
Add a compacting GDT entry allocator, for TSS and LDT selectors.
Enable modifying %fs and %gs with PT_SETREGS.
Sanitize various bits of code.
