* rs6000-nat.c (exec_one_dummy_insn, regmap): Add gdbarch as parameter

	and replace current_gdbarch by gdbarch.

	(store_register): Update call for exec_one_dummy_insn.
	(fetch_register, store_register): Update call of regmap.

	* ppcnbsd-nat.c (getregs_supplies, getfpregs_supplies): Add gdbarch as
	parameter and replace current_gdbarch by gdbarch.

	(ppcnbsd_store_inferior_registers): Use get_regcache_arch to get at
	the current architecture. Update call for getregs_supplies and
	getfpregs_supplies.
	(ppcnbsd_fetch_inferior_registers): Likewise.

	* ppcobsd-nat.c (getfpregs_supplies): Add gdbarch as parameter and
	replace current_gdbarch by gdbarch.
	(ppcobsd_fetch_registers, ppcobsd_store_registers): Use
	get_regcache_arch to get at the current architecture. Update call for
	getfpregs_supplies.
