Browse Source 
This removes yet another instance of a deprecated_xfer_memory user.

Completely untested.

gdb/
2014-02-26  Pedro Alves  <palves@redhat.com>

	* nto-procfs.c (procfs_xfer_memory): Adjust interface as a
	to_xfer_partial helper.  Rewrite.
	(procfs_xfer_partial): New function.
	(init_procfs_ops): Don't install a deprecated_xfer_memory hook.
	Install a to_xfer_partial hook.
