The value in EAX has an 8 bit field for the linear address size and one for
the physical address size when calling that function. A recent change
implemented it but returned 0xff for both of those fields. That implies that
linear and physical addresses are 255 bits wide which is wrong. When using the
KVM CPU model this causes an error, presumably because some of those bits are
actually reserved, or the CPU or kernel realizes 255 bits is a bad value.
This change makes those values 48.
Note that clflush is only being enabled. It is not implemented
in actual. A warning is printed if the cpu encounters a clflush
instruction. We need to enable this instruction in cpuid since
JRE 1.7 tests for it.
Ran all the source files through 'perl -pi' with this script:
s|\s*(};?\s*)?/\*\s*(end\s*)?namespace\s*(\S+)\s*\*/(\s*})?|} // namespace $3|;
s|\s*};?\s*//\s*(end\s*)?namespace\s*(\S+)\s*|} // namespace $2\n|;
s|\s*};?\s*//\s*(\S+)\s*namespace\s*|} // namespace $1\n|;
Also did a little manual editing on some of the arch/*/isa_traits.hh files
and src/SConscript.
