The generic LED code now makes sure that suspended devices don't blink,
so we no longer need to do it ourselves. For the suspend to disk case,
however, we need to make sure that we don't blink if the PMU sysdev
was suspended before the LED device.Signed-off-by: Johannes Berg

Fix the flakiness in the CUDA ADB driver on m68k macs (keypresses getting
wedged down or ADB just going AWOL altogether).The only IRQ used by this driver is the VIA shift register IRQ. The PowerMac
conditional code disables the other VIA IRQ sources, so don't mess with the
other IRQ flags in the common code -- m68k macs need them.When polling, don't disable local interrupts when we only need to disable the
CUDA interrupt.Unless polling, don't clear the shift register IRQ flag. On m68k macs this
creates a race that often breaks CUDA ADB.Tested on Quadra 840av and LC630 (both m68k); also Beige G3 (powerpc).

Fix a crash caused by requests placed in the queue with the completed flag
already set. This lead to some ADB_SYNC requests returning early and their
request structs being popped off the stack while still queued. Stack corruption
ensued or an invalid request callback pointer was invoked or both. Eliminate
macii_retransmit() and its buggy implementation of macii_write(). Have
macii_queue_poll() fully initialise the request queues.Fix a bug in macii_queue_poll() where the last_req pointer was not being set.
This caused some requests to leave the queue before being completed (and would
also corrupt the stack under certain conditions).Fix a race in macii_start that could set the state machine to "reading" while
current_req was null.No longer send poll commands with the ADBREQ_REPLY flag -- doing that caused
the replies to be stored in the request buffer where they were forgotten
about.Don't autopoll by continuously sending new Talk commands. Get the controller to
do that for us. This reduces the ADB interrupt rate on an idle bus to about 5
per second. Only autopoll the devices that were probed.Explicitly clear the interrupt flag when polling.
Use disable_irq rather than local_irq_save when polling.
Remove excess local_irq_save/restore pairs.
Improve bus timeout and service request detection.
Remove unused code (last_reply, adb_dir etc) and unneeded code (prefix_len,
first_byte etc).Change TIP and TACK to their correct names on this ADB controller (ST_EVEN and
ST_ODD).Add some commentry.
Add a generous quantity of sanity checks (BUG_ONs).
Let m68k macs use the adb_sync boot param too.
Tested on Mac II, Mac IIci, Quadra 650, Quadra 700 etc.

Move the setting/unsetting of pmac_backlight into the
backlight core instead of doing it in each driver.Signed-off-by: Richard Purdie
-
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.

Remove uneeded owner field from backlight_properties structure.
Nothing uses it and it is unlikely that it will ever be used. The

The semantic effect of insert_at_head is that it would allow new registered
sysctl entries to override existing sysctl entries of the same name. Which is
pain for caching and the proc interface never implemented.I have done an audit and discovered that none of the current users of
register_sysctl care as (excpet for directories) they do not register
duplicate sysctl entries.So this patch simply removes the support for overriding existing entries in
the sys_sysctl interface since no one uses it or cares and it makes future
enhancments harder.Signed-off-by: Eric W. Biederman

After Al Viro (finally) succeeded in removing the sched.h #include in module.h
recently, it makes sense again to remove other superfluous sched.h includes.
There are quite a lot of files which include it but don't actually need
anything defined in there. Presumably these includes were once needed for
macros that used to live in sched.h, but moved to other header files in the
course of cleaning it up.To ease the pain, this time I did not fiddle with any header files and only
removed #includes from .c-files, which tend to cause less trouble.Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
configs in arch/arm/configs on arm. I also checked that no new warnings were
introduced by the patch (actually, some warnings are removed that were emitted
by unnecessarily included header files).Signed-off-by: Tim Schmielau

Many struct file_operations in the kernel can be "const". Marking them const
moves these to the .rodata section, which avoids false sharing with potential
dirty data. In addition it'll catch accidental writes at compile time to
these shared resources.[akpm@sdl.org: dvb fix]
