Makefile: add optimizing flags vor neon-vfpv4
Update linux kernel from 3.4.79 to 3.4.80
ARM: Use -mcpu=cortex-a15 when targeting MSM Krait CPUs
Enable compiler optimizations specific to the Cortex-A15
processor when targeting MSM Krait CPUs. This is necessary
take advantage of the UDIV/SDIV instructions supported by
these processors. To accomplish this, we need to remove the
-march=armv7-a ISA restriction from the compiler options
because 'cortex-a15' is a superset of 'armv7-a'.
