[PATCH 1/2] ARC: gdbserver breakage in Big-Endian configuration #1

[Based on mainline commit 502a0c775c7f0a: "ARC: pt_regs update #5"] gdbserver needs @stop_pc, served by ptrace, but fetched from pt_regs differently, based on in_brkpt_traps(), which in turn relies on additional machine state in pt_regs->event bitfield. unsigned long orig_r8:16, event:16;

Hi Greg, I'd posted these patches for stable backport. Do I need to do anything more to get them included. https://patchwork.kernel.org/patch/2841153/ [1/2] ARC: gdbserver breakage in Big-Endian configuration #1] https://patchwork.kernel.org/patch/2

Exception handling keeps additional state (whether exception was Trap and if it was due to a breakpoint) in pt_regs->event, a bitfield member unsigned long orig_r8:16, event:16; A bitfield esentially has an "offset" and a "length". What I wasn't aware of was that, bitfields in a union loo
