CPUInfo updates

A new release of cpuinfo is now available. cpuinfo is both a library and a sample program to gather information about the underlying processor. In particular, it gathers information about the caches hierarchy and instruction sets supported by the CPU. Here are the changes:

• Relicense the library under LGPL
• Add Perl bindings
• Add new ppc CPUs (PA6T-1682M, PowerPC 750CL and 970GX)
• Fix detection of VIA processors (C3, C7)
• Fix detection of early AMD processors (K5, K6)
• Fix detection of early Intel processors (Pentium III)
• Fix caches detection for HP-UX/ia64 (use machinfo tool)
• Fix caches detection for some VIA C3 & AMD Duron (errata)
• Add more ia64 standard feature flags (SIMD, POPCOUNT)
• Add more x86 feature flags (3DNow!, SSE4.1, SSE4.2, SSE4A, POPCNT, ABM)
• Add more ppc feature flags (gfxopt, mfcrf, popcntb, fprnd, mfpgpr)

A few docs worth reading:

• AMD CPUID Specification updates (ABM, SSE4A)
• Software Optimization Guide for AMD Family 10h Processors (K10, Barcelona)
• Intel® SSE4 Programming Reference (SSE4.1 in Penryn, SSE4.2 in Nehalem)
• P.A. Semi PWRfficient PA6T-1682M (product brief)
