Vineet Gupta	16f9afe651	ARC: pt_regs update #3: Remove unused gutter at start of callee_regs ... This is trickier than prev two: * context switching code saves kernel mode callee regs in the format of struct callee_regs thus needs adjustment. This also reduces the height of topmost kernel stack frame by 1 word. * Since kernel stack unwinder is sensitive to height of topmost kernel stack frame, that needs a word of adjustment too. ptrace needs a bit of updating since pt_regs now diverges from user_regs_struct.

Vineet Gupta	c08098f28e	ARC: Last bits (stubs) to get to a running kernel with UART ... This was part of port buildup strategy from Arnd to have a minimal kernel at first and then add optional features (stacktracing, ptrace, smp, kprobes, oprofile....)
