Dan Williams 12f188f2e5 ueagle-atm: fix PHY signal initialization race
A race exists when initializing ueagle-atm devices where the generic atm
device may not yet be created before the driver attempts to initialize
it's PHY signal state, which checks whether the atm device has been
created or not.  This often causes the sysfs 'carrier' attribute to be
'1' even though no signal has actually been found.

uea_probe
   usbatm_usb_probe
      driver->bind (uea_bind)
         uea_boot
            kthread_run(uea_kthread)     uea_kthread
      usbatm_atm_init                       uea_start_reset
         atm_dev_register                      UPDATE_ATM_SIGNAL

UPDATE_ATM_SIGNAL checks whether the ATM device has been created and if
not, will not update the PHY signal state.  Because of the race that
does not always happen in time, and the PHY signal state remains
ATM_PHY_SIG_FOUND even though no signal exists.

To fix the race, just create the kthread during initialization, and only
after initialization is complete, start the thread that reboots the
device and initializes PHY state.

flush_scheduled_work() is being deprecated.  Directly flush or cancel
work items instead.

* u_ether, isp1301_omap, speedtch conversions are straight-forward.

* ochi-hcd should only flush when quirk_nec() is true as otherwise the
  work wouldn't have been initialized.

* In oti6858, cancel_delayed_work() + flush_scheduled_work() ->
  cancel_delayed_work_sync().

Dan Williams d9ca676bcb atm: correct sysfs 'device' link creation and parent relationships
The ATM subsystem was incorrectly creating the 'device' link for ATM
nodes in sysfs.  This led to incorrect device/parent relationships
exposed by sysfs and udev.  Instead of rolling the 'device' link by hand
in the generic ATM code, pass each ATM driver's bus device down to the
sysfs code and let sysfs do this stuff correctly.

The command endpoint is either a bulk or interrupt endpoint, but using
the wrong type of transfer causes an error if CONFIG_USB_DEBUG is
enabled after commit f661c6f8c6, which
checks for this mismatch.

Detect which type of endpoint it is and use a bulk/int URB as
appropriate. There are other function calls specifying a bulk pipe,
but usb_clear_halt doesn't use the pipe type (only the endpoint) and
usb_bulk_msg auto-detects interrupt transfers.

Tejun Heo 5a0e3ad6af include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h
percpu.h is included by sched.h and module.h and thus ends up being
included when building most .c files.  percpu.h includes slab.h which
in turn includes gfp.h making everything defined by the two files
universally available and complicating inclusion dependencies.

percpu.h -> slab.h dependency is about to be removed.  Prepare for
this change by updating users of gfp and slab facilities include those
headers directly instead of assuming availability.  As this conversion
needs to touch large number of source files, the following script is
used as the basis of conversion.

  http://userweb.kernel.org/~tj/misc/slabh-sweep.py

The script does the followings.

* Scan files for gfp and slab usages and update includes such that
  only the necessary includes are there.  ie. if only gfp is used,
  gfp.h, if slab is used, slab.h.

* When the script inserts a new include, it looks at the include
  blocks and try to put the new include such that its order conforms
  to its surrounding.  It's put in the include block which contains
  core kernel includes, in the same order that the rest are ordered -
  alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
  doesn't seem to be any matching order.

* If the script can't find a place to put a new include (mostly
  because the file doesn't have fitting include block), it prints out
  an error message indicating which .h file needs to be added to the
  file.

The conversion was done in the following steps.

1. The initial automatic conversion of all .c files updated slightly
   over 4000 files, deleting around 700 includes and adding ~480 gfp.h
   and ~3000 slab.h inclusions.  The script emitted errors for ~400
   files.

2. Each error was manually checked.  Some didn't need the inclusion,
   some needed manual addition while adding it to implementation .h or
   embedding .c file was more appropriate for others.  This step added
   inclusions to around 150 files.

3. The script was run again and the output was compared to the edits
   from #2 to make sure no file was left behind.

4. Several build tests were done and a couple of problems were fixed.
   e.g. lib/decompress_*.c used malloc/free() wrappers around slab
   APIs requiring slab.h to be added manually.

5. The script was run on all .h files but without automatically
   editing them as sprinkling gfp.h and slab.h inclusions around .h
   files could easily lead to inclusion dependency hell.  Most gfp.h
   inclusion directives were ignored as stuff from gfp.h was usually
   wildly available and often used in preprocessor macros.  Each
   slab.h inclusion directive was examined and added manually as
   necessary.

6. percpu.h was updated not to include slab.h.

7. Build test were done on the following configurations and failures
   were fixed.  CONFIG_GCOV_KERNEL was turned off for all tests (as my
   distributed build env didn't work with gcov compiles) and a few
   more options had to be turned off depending on archs to make things
   build (like ipr on powerpc/64 which failed due to missing writeq).

   * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
   * powerpc and powerpc64 SMP allmodconfig
   * sparc and sparc64 SMP allmodconfig
   * ia64 SMP allmodconfig
   * s390 SMP allmodconfig
   * alpha SMP allmodconfig
   * um on x86_64 SMP allmodconfig

8. percpu.h modifications were reverted so that it could be applied as
   a separate patch and serve as bisection point.

Given the fact that I had only a couple of failures from tests on step
6, I'm fairly confident about the coverage of this conversion patch.
If there is a breakage, it's likely to be something in one of the arch
headers which should be easily discoverable easily on most builds of
the specific arch.

Simon Arlott 817db5b34e USB: cxacru: remove cxacru-cf.bin loader
This has never worked properly because wsize passed to
cxacru_cm() is incorrectly set to the number of values
instead of the data bytes. The maximum number of values
that can be set at once is 7 which means the device will
not get enough data to work with and none of the
configuration values will be used.

At least one existing cxacru-cf.bin file contains invalid
data which will prevent the modem from syncing properly.

Fixing it is likely to break existing systems, and the
new sysfs interface for setting configuration parameters
can provide the same functionality. A script is provided
to convert from the original format.

Simon Arlott 4ac37208e9 USB: cxacru: add write-only sysfs attribute for modem configuration
The modem can be configured using CM_REQUEST_CARD_DATA_SET,
although CM_REQUEST_CARD_DATA_GET does not return any data.

Tested by setting the modulation (0x0a) option.

There is a list of parameters in the following archive,
but the meaning of many of them is not well documented:
  http://sourceforge.net/project/shownotes.php?release_id=301825

This source also indicates that the highest parameter set
is 0x4a but this varies by model so an arbitrary limit of
0x7f has been used (the index is a 32-bit integer).

Simon Arlott 885582c48e USB: cxacru: firmware writes on OHCI are slow, log progress
Firmware writing takes 256ms per 4KB with OHCI, which
is very slow compared to 7ms per 4KB with UHCI.

Until I have access to a hardware USB analyser it may
not be possible to determine why this happens.

Instead of appearing to do nothing, log progress when
writing firmware and then log the ATM device information
when finished. Remove an unnecessary 4 second delay.

Simon Arlott 9fc950d322 USB: cxacru: check device isn't being removed during sysfs calls
It is possible for usb_get_intfdata() to return NULL if
sysfs is accessed while the module is being unloaded or
the device is being removed.

Move the access code to an inline function in usbatm.h,
and return -ENODEV if any of the pointers are NULL.

It should not be possible for the instance data or atm
device to be invalid until after unbind() completes and
the sysfs attributes have been removed.

Simon Arlott 5d0a9c7932 USB: cxacru: check data length is not negative
When attempting to read data that is not actually
an array of values, the length may be negative
which causes an Oops due to a likely access off
the end of the data array.

This bug should not occur under normal use unless
the device returns an invalid response.

Johannes Berg 9ebfbd45f9 firmware_class: make request_firmware_nowait more useful
Unfortunately, one cannot hold on to the struct firmware
that request_firmware_nowait() hands off, which is needed
in some cases. Allow this by requiring the callback to
free it (via release_firmware).

Additionally, give it a gfp_t parameter -- all the current
users call it from a GFP_KERNEL context so the GFP_ATOMIC
isn't necessary. This also marks an API break which is
useful in a sense, although that is obviously not the
primary purpose of this change.

This patch (as1150) fixes a problem in the speedtch driver.  When it
resets the modem during probe it will be unbound from the other
interfaces it has claimed, because it doesn't define a pre_reset and a
post_reset method.

The patch defines "do-nothing" methods.  This fixes Bugzilla #11767.
