This patch changes the initialization of alps tdee4 tuner in

written specifically for Cablestar cards by Patrick Boettcher. This

before enabling external interrupts. The external interrupt at the

Driver for the Silicon Motion SM501 multifunction device framebuffer

This driver supports both the CRT and LCD panel heads, with some simple
acceleration for the cursor plotting and support for screen panning.  There
is no current support for bitblt/drawing engines, which should be added at
a later date.

This has been tested on a number of configurations, including PCI and
generic-bus, on PPC, ARM and SH4

da68d61f89 [PATCH] remove modpost false warnings on ARM
This patch stops "modpost" from issuing erroneous modpost warnings on ARM
builds, which it's been doing since since maybe last summer.  A canonical
example would be driver method table entries:

  WARNING: <path> - Section mismatch: reference to .exit.text:<name>_remove
	from .data after '$d' (at offset 0x4)

That "$d" symbol is generated by tools conformant with ARM ABI specs; in
this case it's a symbol **in the middle of** a "<name>_driver" struct.

The erroneous warnings appear to be issued because "modpost" whitelists
references from "<name>_driver" data into init and exit sections ...  but
doesn't know should also include those "$d" mapping symbols, which are not
otherwise associated with "<name>_driver" symbols.

This patch prevents the modpost symbol lookup code from ever returning
those mapping symbols, so it will return a whitelisted symbol instead.
Then things work as expected.

Now to revert various code-bloating "fixes" that got merged because of this
modpost bug....

5d4675a811 [PATCH] at91_rtc updates
Various bug fixes to the at91rm9200 RTC:

 - alarm:  setalarm() should pay attention to the "enabled" flag

 - init:  cleaner handling of the wakeup flags, which cpu init should
   really have set up.  Doing it here is just a workaround.

 - linkage:  since the at91_rtc driver probe() routine is in the init
   section, it should use platform_driver_probe() instead of leaving
   that pointer around in the driver struct after init section removal.

 - linkage:  likewise, remove() belongs in the exit section.

Among other things, the init and alarm changes ensure that this driver
handles the new sysfs "wakealarm" attribute properly.

32b49da46c [PATCH] rtc-sa1100 rtc_wklarm.enabled bugfixes
Some rtc-sa1100 bugfixes:

 - The read_alarm() method reports the rtc_wkalrm.enabled field properly.
   This patch is already in the handhelds.org tree.

 - And the set_alarm() method now handles that flag correctly, rather than
   making mismatched {en,dis}able_irq_wake() calls, which trigger runtime
   warning messages.  (Those calls are best made in suspend/resume methods.)

Note that while this SA1100/PXA RTC is fully capable of waking those ARM
processors from sleep states, that mechanism isn't properly supported on
either processor family, or in this driver.  Some boards have board-specific
PM glue providing partial workarounds for the weak generic PM support.

2be3c79046 [PATCH] affs: implement ->drop_inode
affs wants to truncate the inode when the last user goes away, currently it
does that through a potentially racy i_count check in ->put_inode.  But we
already have a method that's called just after the we dropped the last
reference, ->drop_inode.  This patch implements affs_drop_inode to take
advantage of this.

c9ffec4848 [PATCH] autofs4: check for directory re-create in lookup
This problem was identified and fixed some time ago by Jeff Moyer but it fell
through the cracks somehow.

It is possible that a user space application could remove and re-create a
directory during a request.  To avoid returning a failure from lookup
incorrectly when our current dentry is unhashed we need to check if another
positive, hashed dentry matching this one exists and if so return it instead
of a fail.

f50b6f8691 [PATCH] autofs4: fix another race between mount and expire
Jeff Moyer has identified a race between mount and expire.

What happens is that during an expire the situation can arise that a directory
is removed and another lookup is done before the expire issues a completion
status to the kernel module.  In this case, since the the lookup gets a new
dentry, it doesn't know that there is an expire in progress and when it posts
its mount request, matches the existing expire request and waits for its
completion.  ENOENT is then returned to user space from lookup (as the dentry
passed in is now unhashed) without having performed the mount request.

The solution used here is to keep track of dentrys in this unhashed state and
reuse them, if possible, in order to preserve the flags.  Additionally, this
infrastructure will provide the framework for the reintroduction of caching of
mount fails removed earlier in development.
