Microcode fixes for Intel P6-core chips are uploaded to the CPU either
by the BIOS, or by a driver. Linux obviously doesn't have a driver,
which means it has to be done by the BIOS (usually shipped as part of
the BIOS) or we have to get a driver.

The microcode update itself is delivered from Intel as a binary blob.
