Module Name:    src
Committed By:   mrg
Date:           Tue Jul  1 15:27:34 UTC 2008

Modified Files:
        src/sys/arch/x86/include: mtrr.h
        src/sys/arch/x86/x86: mtrr_i686.c

Log Message:
hack around PR#38480:

- rename MTRR_I686_NVAR to MTRR_I686_NVAR_MAX, still set to 8
- store mtrr VCNT value into i686_mtrr_vcnt.  if it is less than 8,
  zero out the relevant parts of mtrr_raw[].msraddr
- replace all usage of MTRR_I686_NVAR with either i686_mtrr_vcnt or
  with MTRR_I686_NVAR_MAX as appropriate
- in i686_mtrr_reload() and mtrr_init_first() don't use mtrr_raw[]
  addresses of 0

still needs a bunch of reworking to handle VCNT > 8 case.
