Ulrich Weigand 7714d83ad4 * inf-ptrace.c (inf_ptrace_register_u_offset): Adapt parameter list.
(inf_ptrace_fetch_register): Add register_u_offset callback parameters
	GDBARCH and STORE_P.  Handle callback (CORE_ADDR) -1 return value.
	(inf_ptrace_store_register): Likewise.
	(inf_ptrace_trad_target): Adapt register_u_offset parameter list.
	* inf-ptrace.h (inf_ptrace_trad_target): Likewise.

	* vax-nat.c (vax_register_u_offset): Adapt parameter list.

	* linux-nat.c (linux_trad_target): Adapt parameter list.
	* linux-nat.h (linux_trad_target): Likewise.

	* alpha-linux-nat.c (alpha_linux_register_u_offset): Adapt parameters.

	* mips-linux-nat.c (mips_linux_cannot_fetch_register): Remove.
	(mips_linux_cannot_store_register): Likewise.
	(mips_linux_register_addr): Add GDBARCH and STORE_P parameters.
	Return (CORE_ADDR) -1 for registers that cannot be fetched or
	stored via ptrace.  Use GDBARCH instead of current_gdbarch.
	(mips64_linux_register_addr): Likewise.
	(mips_linux_register_u_offset): Adapt parameter list.  Pass
	GDBARCH and STORE_P on to mips{64}_linux_register_addr.

	* config/mips/linux.mh (NAT_FILE): Set to config/nm-linux.h.
	* config/mips/nm-linux.h: Delete file.
