[kernel-3.10.21-armv6-qemu.patch] Kernel 3.10.21-armv6 Patch for QEMU #kernel #arm #linux #qemu #raspberrypi
Make the "Arm Versatile" board even more versatile, for QEMU, which can
stick weird processors into things that were never meant to receive them.
Based on: http://unicorn.drogon.net/rpi/linux-arm.patch
