Hi,

this patch adds gdbarch to register_name callback in sh-tdep.c. It also replaces some trivial occurences of current_gdbarch.

Is this ok to commit?

ChangeLog: 


	* sh-tdep.c (sh_sh_register_name, sh_sh3_register_name)
	(sh_sh3e_register_name, sh_sh2e_register_name, sh_sh2a_register_name)
	(sh_sh2a_nofpu_register_name, sh_sh_dsp_register_name)
	(sh_sh3_dsp_register_name, sh_sh4_register_name)
	(sh_sh4_nofpu_register_name, sh_sh4al_dsp_register_name): Add gdbarch
	parameter.
	(fv_reg_base_num, dr_reg_base_num, sh_justify_value_in_reg)
	(sh_next_flt_argreg): Add gdbarch parameter and update caller. Replace
	current_gdbarch by gdbarch.
	(sh_extract_return_value_fpu, sh_store_return_value_fpu): Use
	get_regcache_arch to get at the current architecture by regcache.
