ChangeLog:

Browse Source 
* defs.h (enum info_proc_what): Moved here from linux-nat.c
	* infcmd.c: (info_proc_cmd_1): New function.
	(info_proc_cmd): New function, moved here from equivalent routine
	orignally in linux-nat.c.
	(info_proc_cmd_mappings): Likewise.
	(info_proc_cmd_stat): Likewise.
	(info_proc_cmd_status): Likewise.
	(info_proc_cmd_cwd): Likewise.
	(info_proc_cmd_cmdline): Likewise.
	(info_proc_cmd_exe): Likewise.
	(info_proc_cmd_all): Likewise.
	(_initialize_infcmd): Install "info proc" command and subcommands.

	* target.h (struct target_ops): Add to_info_proc.
	(target_info_proc): Add prototype.
	* target.c (target_info_proc): New function.

	* procfs.c (procfs_info_proc): Add prototype.
	(info_proc_cmd): Rename into ...
	(procfs_info_proc): ... this.  Update argument types as appropriate
	for a to_info_proc implementation.  Handle "what" argument.
	(procfs_target): Install procfs_info_proc.
	(_initialize_procfs): No longer install "info proc" command.

	* linux-nat.c: (enum info_proc_what): Remove.
	(linux_nat_info_proc_cmd_1): Rename into ...
	(linux_nat_info_proc): ... this.  Update argument types as appropriate
	for a to_info_proc implementation.
	(linux_nat_info_proc_cmd): Remove.
	(linux_nat_info_proc_cmd_mappings): Likewise.
	(linux_nat_info_proc_cmd_stat): Likewise.
	(linux_nat_info_proc_cmd_status): Likewise.
	(linux_nat_info_proc_cmd_cwd): Likewise.
	(linux_nat_info_proc_cmd_cmdline): Likewise.
	(linux_nat_info_proc_cmd_exe): Likewise.
	(linux_nat_info_proc_cmd_all): Likewise.
	(linux_target_install_ops): Install linux_nat_info_proc.
	(_initialize_linux_nat): No longer install "info proc" command
	and subcommands.

testsuite/ChangeLog:

	* gdb.base/info-proc.exp: Also run on remote targets.  Main
	"info proc" command is now always present; whether target supports
	actual info proc operation is detected when attempting to issue
	the command.
