* hppa-tdep.c (hppa_stub_unwind_sniffer, hppa_dump_tdep): Replace
	current_gdbarch by gdbarch.
	* hppa-linux-nat.c (fetch_register, store_register)
	(hppa_linux_fetch_inferior_registers)
	(hppa_linux_store_inferior_registers): Use get_regcache_arch or
	get_frame_arch to get at the current architecture by regcache or by
	frame, respectively.
	* hppa-hpux-tdep.c (hppa_hpux_skip_trampoline_code
	(hppa_hpux_unwind_adjust_stub): Likewise.
	* hppa-hpux-nat.c (hppa_hpux_fetch_register, hppa_hpux_store_register)
	(hppa_hpux_fetch_inferior_registers)
	(hppa_hpux_store_inferior_registers): Likewise.
