From: Ulrich Weigand <uweigand@de.ibm.com>
Date: Wed, 25 Apr 2007 22:22:11 +0000
Subject: 	* mips-linux-nat.c: No longer include "gdbcore.h". 
 (mips_linux_register_addr): Move from mips-linux-tdep.c. 
 (mips64_linux_register_addr): Likewise. 
 (mips_linux_register_u_offset): Call mips_linux_register_addr or 
 mips64_linux_register_addr instead of register_addr. 	* mips-linux-tdep.c
 (mips_linux_register_addr, 	mips64_linux_register_addr): Move to
 mips-linux-nat.c. 	(register_addr): Remove. 	(register_addr_data,
 init_register_addr_data): Remove. 	(_initialize_mips_linux_tdep): Do not
 initialize register_addr_data. 	(set_mips_linux_register_addr):
 Remove. 	(mips_linux_init_abi): Do not call
 set_mips_linux_register_addr. 	* Makefile.in (mips-linux-nat.o): Update
 dependencies.
