[Lucid SRU 0/5] Enable Sandybridge AVX

[Steve Conklin]

BugLink: http://bugs.launchpad.net/bugs/607653

These patches are from upstream but have not been queued for stable.

Intel Advanced Vector Extensions (AVX) introduce 256-bit vector processing capability. it's the next generation of the SSE instructions, and useful for many things, especially multi-media codecs. More about AVX at http://software.intel.com/sites/avx.

AVX enablement has taken place as follows:
- Kernel xsave/xrestore (done in 2.6.28)
- Kernel patch enabling AVX (done in 2.6.30)
- gcc( done in 4.4.2) ; binutils (done in 2.20.51.0.2 )

glibc 2.11 has AVX support, so we need to enable debugging support in the kernel to support glibc.
