[PATCH 0/5] Enable Drivers for Intel MIC X100 Coprocessors.
An Intel MIC X100 device is a PCIe form factor add-in coprocessor
card based on the Intel Many Integrated Core (MIC) architecture
that runs a Linux OS. It is a PCIe endpoint in a platform and therefore
implements the three required standard address spaces i.e. configuration,
memory and I/O. The host OS loads a device driver as is typical for
PCIe devices. The card itself runs a bootstrap after
