* alpha-linux-tdep.c: Include "gdb_string.h", "regset.h",

Browse source 
and "regcache.h".
	(alpha_linux_supply_gregset, alpha_linux_supply_fpregset): New.
	(alpha_linux_gregset, alpha_linux_fpregset): New variables.
	(alpha_linux_regset_from_core_section): New function.
	(alpha_linux_init_abi): Install it.
	* alpha-linux-nat.c: Do not include "gdbcore.h".  Include
	"alpha-tdep.h", <sys/ptrace.h>, <alpha/ptrace.h>,
	<sys/procfs.h>, and "gregset.h".
	(ALPHA_REGSET_BASE, ALPHA_REGSET_UNIQUE, ALPHA_UNIQUE_PTRACE_ADDR):
	Move from config/alpha/nm-linux.h.
	(supply_gregset, fill_gregset, supply_fpregset, fill_fpregset): Copy
	from alpha-nat.c.
	(alpha_linux_register_u_offset): Inline register_addr from alpha-nat.c.
	* alpha-nat.c: Remove #ifdef __linux__ section.
	(fetch_elf_core_registers, alpha_elf_core_fns): Remove.
	(_initialize_core_alpha): Do not register alpha_elf_core_fns.
	(ALPHA_UNIQUE_PTRACE_ADDR, ALPHA_REGSET_UNIQUE): Define unconditionally.
	(ALPHA_REGSET_BASE): Move from config/alpha/nm-osf.h.
	* config/alpha/alpha-linux.mh (NAT_FILE): Set to config/nm-linux.h.
	(NATDEPFILES): Remove alpha-nat.o.
	* config/alpha/nm-linux.h: Delete file.
	* config/alpha/nm-osf.h (ALPHA_REGSET_BASE): Move to alpha-nat.c.
	* Makefile.in (alpha-linux-nat.o): Update dependencies.
	(alpha-linux-tdep.o): Likewise.
