There are a *LOT* of memory debugging options.  They are just scattered
all over the "Kernel Hacking" menu.  Sure, "memory debugging" is a very
vague term and it's going to be hard to make absolute rules about what
goes in here, but this has to be better than what we had before.

This does, however, leave out the architecture-specific memory
debugging options (like x86's DEBUG_SET_MODULE_RONX).  There would need
to be some substantial changes to move those in here.  Kconfig can not
easily mix arch-specific and generic options together: it really
requires a file per-architecture, and I think having an
arch/foo/Kconfig.debug-memory might be taking things a bit too far

HID: wacom: Intuos4 battery charging changes

Intuos4 WL is separately reporting power supply and battery
charging status - now hid-wacom is using that information.
Previously hid-wacom was wrongly treating "battery charging" bit
as "power supply connected". Now it should report battery charging,
battery discharging, battery full and power supply status.

Intuos4 WL sends reports when is in use (obvious) and when unplugging
power supply. If means that if the device is being charged, but it's not
being used it will never report "battery full". The same problem happens
after the device has been connected, but it's not in use - the
battery/ac status will be incorrect. Currently there is no mechanism to
ask the device to send a report containing battery/ac status.

    md/raid10: Allow skipping recovery when clean arrays are assembled

Causes raid10 to skip a recovery in certain cases where it is safe to
do so.  Unfortunately it also causes a reshape to be skipped which is
never safe.  The result is that an attempt to reshape a RAID10 will
appear to complete instantly, but no data will have been moves so the
array will now contain garbage.
(If nothing is written, you can recovery by simple performing the
reverse reshape which will also complete instantly).

Bug was introduced in 3.10, so this is suitable for 3.10-stable.

that the new minimum number of devices is large enough (which is
good), but it does so also after the reshape has started (bad).

This is bad because
 - the calculation is now wrong as mddev->raid_disks has changed

 - it is pointless because it is now too late to stop.

Currently, when a disconnect is requested by the user (via NBD_DISCONNECT
ioctl) the return from NBD_DO_IT is undefined (it is usually one of
several error codes).  This means that nbd-client does not know if a
manual disconnect was performed or whether a network error occurred.
Because of this, nbd-client's persist mode (which tries to reconnect after
error, but not after manual disconnect) does not always work correctly.

This change fixes this by causing NBD_DO_IT to always return 0 if a user
requests a disconnect.  This means that nbd-client can correctly either
persist the connection (if an error occurred) or disconnect (if the user
requested it).

rapidio: change endpoint device name format

Change endpoint device name format to use a component tag value instead of
device destination ID.

RapidIO specification defines a component tag to be a unique identifier
for devices in a network.  RapidIO switches already use component tag as
part of their device name and also use it for device identification when
processing error management event notifications.

Forming an endpoint's device name using its component tag instead of
destination ID allows to keep sysfs device directories unchanged in case
if a routing process dynamically changes endpoint's destination ID as a
result of route optimization.

This change should not affect any existing users because a valid device
destination ID always should be obtained by reading "destid" attribute and
not by parsing device name.

This patch also removes switchid member from struct rio_switch because it
simply duplicates the component tag and does not have other use than in

rapidio: update enumerator registration mechanism

Update enumeration/discovery method registration mechanism to allow
loading enumeration/discovery methods before all mports are registered.

Existing statically linked RapidIO subsystem expects that all available
RapidIO mport devices are initialized and registered before the
enumeration/discovery method is registered.  Switching to loadable mport
device drivers creates situation when mport device driver can be loaded
after enumeration/discovery method is attached (e.g., loadable mport
driver in a system with statically linked RapidIO core and enumerator).
This also will happen in a system with hot-pluggable RapidIO controllers.

To remove the dependency on the initialization/registration order this
patch introduces enumeration/discovery registration mechanism that
supports arbitrary registration order of mports and enumerator/discovery
methods.

The following registration rules are implemented:
- only one enumeration/discovery method can be registered for given mport ID
  (including RIO_MPORT_ANY);
- when new enumeration/discovery methods tries to attach to the registered mport
  device, method with matching mport ID will replace a default method previously
  registered for given mport (if any);
- enumeration/discovery method with target ID=RIO_MPORT_ANY will be attached
  only to mports that do not have another enumerator attached to them;
- when new mport device is registered with RapidIO subsystem, registration
  routine searches for the enumeration/discovery method with the best matching
  mport ID;

rapidio/rionet: rework driver initialization and removal

Rework probe/remove routines to prevent rionet driver from monopolizing
target RapidIO devices.  Fix conflict with modular RapidIO switch drivers.

Using one of RapidIO messaging channels rionet driver provides a service
layer common to all endpoint devices in a system's RapidIO network.  These
devices may also require their own specific device driver which will be
blocked from attaching to the target device by rionet (or block rionet if
loaded earlier).  To avoid conflict with device-specific drivers, the
rionet driver is reworked to be registered as a subsystem interface on the
RapidIO bus.

The reworked rio_remove_dev() and rionet_exit() routines also include
handling of individual rionet peer device removal which was not supported
before.

11 years agorapidio: convert switch drivers to modules
Alexandre Bounine [Wed, 3 Jul 2013 22:08:50 +0000 (15:08 -0700)]
rapidio: convert switch drivers to modules

Rework RapidIO switch drivers to add an option to build them as loadable
kernel modules.

This patch removes RapidIO-specific vmlinux section and converts switch
drivers to be compatible with LDM driver registration method.  To simplify
registration of device-specific callback routines this patch introduces
rio_switch_ops data structure.  The sw_sysfs() callback is removed from
the list of device-specific operations because under the new structure its
functions can be handled by switch driver's probe() and remove() routines.

If a specific switch device driver is not loaded the RapidIO subsystem
core will use default standard-based operations to configure a switch.
Because the current implementation of RapidIO enumeration/discovery method
relies on availability of device-specific operations for error management,
switch device drivers must be loaded before the RapidIO
enumeration/discovery starts.

This patch also moves several common routines from enumeration/discovery
module into the RapidIO core code to make switch-specific operations
accessible to all components of RapidIO subsystem.

/dev/oldmem: Remove the interface

/dev/oldmem provides the interface for us to access the "old memory" in
the dump-capture kernel.  Unfortunately, no one actually uses this
interface.

And this interface could actually cause some real problems if used on ia64
where the cached/uncached accesses are mixed.  See the discussion from the
link: https://lkml.org/lkml/2013/4/12/386.
So Eric suggested that we should remove /dev/oldmem as an unused piece of
code.
