f750dde2c0 Fixed issue #4: Advanced Power Management Features 
- Move detection of constant_tsc to common; it is spec'd in Intel docs
- Fix broken interpretation of EAX in leaf 80000000h: it shows max
  800000xx-value, not max xx-value. This causes, for example, to seek
  for extended features on Pentium II, where the extended leafs aren't
  supported by the CPU at all.
  This is only in common feature detection. AMD detection is fine.
- Add detection of a few new features in AMD leaf 80000007h: cbp (core
  performance boost), aperfmperf (APERF/MPERF MSRs supported),
  pfi (processor feedback interface) and pa (processor accumulator).

"make test" is broken right now, to be fixed in a subsequent commit.

2914256486 Update ChangeLog; bump the version to 0.2.1 everywhere. 
Previously, 0.2.1 was mentioned in libcpuid.h, but this was not,
actually, in effect; it wasn't mentioned in autoconf and Visual Studio
project files. Also, cpuid_lib_version() still returned "0.2.0".

23c629295a Add *.sln, *.vcproj files to automake for "make dist" to work. 
The .am files contained obsolete data (to include libcpuid.sln/libcpuid.vcproj
in a dist). These files are now in libcpuid_vc71.* and libcpuid_vc9.* flavours,
thus this change. "make dist" now works.

c5b459c5b2 Fix issue #2: There is no configure binary and get some statements while building it. 
There's no reason to keep a configure binary in source control. I added the
necessary steps to create it in the README.

45651ef7bc Merge 141243f from http://github.com/eloaders/libcpuid 
This adds support for x2apic detection. This is not a direct merge, since

- the feature is spelled as 'x2apic' instead of 'x2APIC', for consistency with other flags;
- tests are added
- the id of the feature is moved to the end of the cpu_feature_t enum, for binary
  compatibility.

0f90f77910 Fixed a crash with gcc-4.6.3 in 32-bit mode. The compiler aggressively optimizes exec_cpuid(), making the stack layout not exactly what the assembly expects. Rearranging instructions seems to fix things. The 64-bit changes aren't tested, though.

3623c5639d Added SSE unit size detection, based on the AMD extended leaf 1a, bit 0. Added a field in cpu_id_t to specify SSE unit size. Also added a hints array, similar to the flags array, which will hold various detection-specific hints. The only currently present hint is about the way the SSE unit size is inferred - whether it is based on the old CPU family/model guesswork (which fails for the AMD Brazos-based cores). Also, added the features XOP, FMA4, TBM and F16C. Changed the library version due to breaking binary compatibility.

0bd7a6d83f The logic behind the big IFDEF at msrdriver.c was wrong. You could compile a 32-bit build and run it on 64-bit windows, and in this case you will still need the 64-bit driver. So the platform detection is made runtime, and the correct driver for the platform is extracted on demand.
