Module Name: src
Committed By: abs
Date: Thu Dec 15 09:38:21 UTC 2011
Modified Files:
src/sys/arch/x86/include: mtrr.h specialreg.h
src/sys/arch/x86/x86: mtrr_i686.c
Log Message:
Increase MTRR_I686_NVAR_MAX from 8 to 16. Avoids
"FIXME: more than 8 MTRRs (10)" message on booting Thinkpad W520 and
similar. While here replace a magic number with MTRR_I686_NVAR_MAX * 2
