Similarly, the vast majority of key handlers has no need for such. 1: serial: fake IRQ-regs context in poll handlers 2: keyhandler: drop regs parameter from handle_keyregs() 3: serial: drop serial_rx_fn's regs parameter 4: PV-shim: drop pv_console_rx()'s regs parameter 5: serial: drop serial_[rt]x_interrupt()'s regs parameter 6: IRQ: drop regs parameter from handler functions 7: x86/APIC: drop regs parameter from direct vector handler functions 8: consolidate do_bug_frame() / bug_fn_t I think it is now only the lack of an ack for the 1st patch which is keeping this series from going in.
