Several people have reported failures in dynamic major device number handling
due to the recent changes in there to avoid handing out the local/experimental
majors.
Rolf reports that this is due to a gcc-4.1.0 bug.
The patch refactors that code a lot in an attempt to provoke the compiler into
behaving.

Somehow we got the layout of the v3 superblock wrong, which causes crashes due
to overindexing of the buffer_head array in statfs on large fielsystems.

If one of clear_bit, change_bit or set_bit is defined as a do { } while (0)
function usage of these functions in parenthesis like
(foo_bit(23, &var))
while be expaned to something like
(do { ... } while (0)}).
resulting in a build error. This patch removes the useless parenthesis.

Instead, platform-specific code enables the ports supported by the
hardware. After this patch, these config variables are only used in

Aculab E1/T1 PMXc cPCI carrier card cards present a natsemi on the cPCI
bus with an oversized EEPROM using a direct MII<->MII connection with no
PHY. This patch adds a new device table entry supporting these cards.

This patch provides code paths which allow the natsemi driver to use the
external MII port on the chip but ignore any PHYs that may be attached to it.
The link state will be left as it was when the driver started and can be
configured via ethtool. Any PHYs that are present can be accessed via the MII
ioctl()s.
This is useful for systems where the device is connected without a PHY
or where either information or actions outside the scope of the driver
are required in order to use the PHYs.

flush_scheduled_work() in net_device->close has a slight tendency
to deadlock with tasks on the workqueue that hold RTNL.
rtl8169_close/down simply need the recovery tasks to not meddle
with the hardware while the device is going down.

fb_info->bl_mutex is badly thought out and the backlight class doesn't
need it if the framebuffer/backlight register/unregister order is
consistent, particularly after the backlight locking fixes.
Fix the drivers to use the order:
backlight_device_register()
register_framebuffer()
unregister_framebuffer()
backlight_device_unregister()
and turn bl_mutex into a lock for the bl_curve data only.

Remove uneeded update_status call from chipsfb.c since the

too.
Signed-off-by: Richard Purdie <rpurdie@rpsys.net>
|
|
The backlight class wants notification whenever the console is blanked
but doesn't get this when hardware blanking fails and software blanking
is used. Changing FB_EVENT_BLANK to report both would be a behaviour
change which could confuse the console layer so add a new event for
software blanking and have the backlight class listen for both.

Convert internal semaphore to a mutex
Signed-off-by: Richard Purdie <rpurdie@rpsys.net>
|
|
backlight_device->sem has a very specific use as documented in the
header file. The external users of this are using it for a different
reason, to serialise access to the update_status() method.
backlight users were supposed to implement their own internal
serialisation of update_status() if needed but everyone is doing
things differently and incorrectly. Therefore add a global mutex to
take care of serialisation for everyone, once and for all.
Locking for get_brightness remains optional since most users don't
need it.
Also update the lcd class in a similar way.
