- Authentication-results: sourceware.org; auth=none
As mentioned in http://www.spinics.net/lists/arm-kernel/msg290896.html, we should change gdb's notion of cpsr to be 64bit.
OK? Build and tested for aarch64-linux-gnu with no regressions.
I also double checked to make sure that what is passed down from the kernel (via sigcontext), is the full 64bit.
Thanks,
Andrew Pinski
