[PATCH] fix smc-mca cleanup breakage
The latest set of smc-mca fixes broke the driver. Apparently, it wasn't
realised that request_region() actually returns a pointer to the region
you're requesting if it can. Without this fix, the smc-mca cannot
attach to any device.

[PATCH] PROT_GROWSDOWN/PROT_GROWSUP flags for mprotect
There is currently no clean and efficient way to apply mprotect to all of a
program's stack, i.e. to the moving edge of a GROWSDOWN or GROWSUP mapping.
Some processes want to change these protections, particularly to set or
clear the PROT_EXEC bits on stack space. As it is, an mprotect done to
cover the precise edge page of the mapping will have the desired effect of
changing the protection for existing pages and having that new protection
carried over to new pages grown later. But there is no very reasonable way
of ascertaining where the edge of the mapping is if it might have grown in
the past beyond the usage at the moment. An mprotect call that doesn't
cover the edge page splits the mapping and doesn't do what we need.
This patch adds flags that can be OR'd into the protection bits in an
mprotect system call. PROT_GROWSDOWN means the memory lies in a GROWSDOWN
mapping and the start address of the region to be changed should be
extended down to the current low page of that mapping. Similarly,
PROT_GROWSUP means the pages lie in a GROWSUP mapping and the length of the
region to be changed should be extended up to include its highest page.
These flags also explicitly request the (already implicit) behavior that
the protection change applied to the lowest/highest page of a growing
mapping is passed on to new pages grown later. There are no other changes
to the mprotect behavior; in particular, the boundary in the non-growing
direction (the end address computed from the start+len arguments in the
GROWSDOWN case, and the start argument in the GROWSUP case) is as given by
the arguments to the system call. This is desireable in the use of this
call by a process on its stack, so it can change the protections of the
growing mapping used for program stack distinctly from the protections on
the arguments, environment, and AT_* data from exec.

[PATCH] USB: usb_set_configuration() rework (v2)
This is the latest update of the patch resolving bugs in how device
configurations were reflected in the driver model. It addresses
the last significant problems I know about in that area.
- Moves code around so that usb_set_configuration() updates sysfs
to reflect the current configuration. Previously, that only
worked right for the initial configuration chosen by khubd.
* Previous interfaces are inaccessible. The code to handle this
moved from usb_disconnect() into usb_disable_device(), which
is now called both on disconnect and set_configuration paths.
* There are new interfaces. The code to handle this moved
from usb_new_device() into usb_set_configuration().
* Resolves a double-refcount problem with USB interfaces,
by not getting the extra reference in the first place
and switching to use device_del() to disable interfaces.
* Comments a similar double-refcount problem with usb
devices (not interfaces).
Its kerneldoc is updated appropriately. The main point being
that calling usb_set_configuration() in driver probe() methods
is even more of a no-no, since it'll self-deadlock.
- Sysfs names for USB interfaces now include the configuation
number, so that user mode code can't get as easily confused.
Old style: "3-1:0" for configs 2 and 3 (interface zero).
New style: "3-1:2.0" for config 2, "3-3:3.0" for config 3.
- Moves usb_new_device() code around a bit, so that the device
is visible in sysfs before usb_set_configuration() is called.
(Before the devices for that config's interfaces appear.)
- Makes the bConfigurationValue be writable through sysfs, so
device configurations can be easily changed from user mode.
(Or devices can be de-configured, by setting config 0.)
There are devices that can benefit from this functionality;
notably, cdc-acm modems need it right now, so that they can
be told to use the non-proprietary configuration. (Since
the old "change config in probe callback" trick won't work.)
