This commit makes the stack guard page somewhat less visible to user
space. It does this by:

- not showing the guard page in /proc/<pid>/maps

It looks like lvm-tools will actually read /proc/self/maps to figure
out where all its mappings are, and effectively do a specialized
"mlockall()" in user space. By not showing the guard page as part of
the mapping (by just adding PAGE_SIZE to the start for grows-up
pages), lvm-tools ends up not being aware of it.

- by also teaching the _real_ mlock() functionality not to try to lock
the guard page.

That would just expand the mapping down to create a new guard page,
so there really is no point in trying to lock it in place.

It would perhaps be nice to show the guard page specially in
/proc/<pid>/maps (or at least mark grow-down segments some way), but
let's not open ourselves up to more breakage by user space from programs
that depends on the exact deails of the 'maps' file.

Special thanks to Henrique de Moraes Holschuh for diving into lvm-tools
source code to see what was going on with the whole new warning.

"plat_id" is always non-NULL here. There is a zero element on the end
of the m25p_ids[] array and if we hit the end of the loop then plat_id
points to that.

This would lead to a NULL pointer dereference later on in the function.

This is just a cleanup, it doesn't fix any bugs.

These functions all check retlen inconsistently and it generates a
warning in Smatch (http://smatch.sf.net). If retlen were ever NULL it
would cause an oops and the code has been this way since 2006 so someone
would have complained. Also I looked at other places that implemented
the mtd read and write functions and they dereference retlen without
checking.

I removed the checks.

Enable discard support in the DM multipath target.

This discard support depends on a few discard-specific fixes to the
block layer's request stacking driver methods.

Discard requests are optional so don't allow a failed discard to trigger
path failures. If there is a real problem with a given path the
barriers associated with the discard (either before or after the
discard) will cause path failure. That said, unconditionally passing
discard failures up the stack is not ideal. This must be fixed once DM
has more information about the nature of the underlying storage failure.
