[PATCH V4] gic: preserve gic V2 bypass bits in cpu ctrl register

2014-05-06 Thread Feng Kan
This change is made to preserve the GIC v2 bypass bits in the GIC_CPU_CTRL register (also known as the GICC_CTLR register in spec). This code will preserve all bits configured by the bootload regarding v2 bypass group bits. In the X-Gene platform (as well others), the bypass functionality is not ge
