[PATCH 00/26] Eliminate create_proc_read_entry() [RFC]

[David Howells <dhowells@redhat.com>]

Here is a series of patches to eliminate create_proc_read_entry(), replacing it
with proc_create() and proc_create_data() and the use of seq_file facilities.

This requires file_operations structs and open methods to be provided in most
cases, though single_open() and single_open_size() suffice for the actual
translation into the seq_file environment.  I did try and reduce the number of
file_operations structs and open methods added by placing the show function
pointer into seq_file::private in some places.

Certain places (hostap most notably) required conversion of some files into
full seq_file iterators to handle the possibility that large lists might
overrun a single buffer full of data.

This reduces the size of the proc_dir_entry by the removal of the read_proc
pointer, plus the support mechanisms for these have been removed from the
procfs code.

These patches have been compile tested as best I can (apart from SH for which I
don't have a working compiler).  No runtime testing has been done outside of
the core procfs code as I don't have the requisite hardware.

These patches can be seen here also:
