Input: keyboard - fix braille keyboard keysym generation

Keysyms stored in key_map[] are not simply K() values, but U(K()) values,
as can be seen in the KDSKBENT ioctl handler. The kernel-generated
braille keysyms thus need a U() call too.

This patch (as1305) fixes a bug in the irq-enable settings and removes
some related overhead in the runtime PM code.
In __pm_runtime_resume(), within the scope of the original
spin_lock_irq(), we know that irqs are disabled. There's no
reason to go through a pair of enable/disable cycles when
acquiring and releasing the parent's lock.
In __pm_runtime_set_status(), irqs are already disabled when
the parent's lock is acquired, and they must remain disabled
when it is released.

Here is the final set of patches I used to get ffado to work with the
new firewire stack. With these patches, I was able to start ardour
and record from and playback to my PreSonus Inspire1394 from a
(mostly) Fedora 12 system.

Until now, firewire-ohci exposed only the transmit cycle of the last
transmitted packet at each isochronous transmit complete event. This
made it impossible for FFADO (FireWire audio drivers in userspace) to
synchronize audio-out streams. The fix is to store the timestamp of
each packet in the iso xmit event. As a bonus, the transfer status is
stored too.

Calling the START_ISO ioctl with a nonnegative cycle paramater has
never worked. Last night I got around to figuring out why. Most of
this patch is a big comment explaining why we enable an interrupt
source then don't actually do anything when we get one. As the
comment says, we should do more, but we don't have a way to tell
userspace what happened. . .

For CRT hotplug detect status, we have four test results as blue
channel only, green channel only, both blue and green channel, and
no channel attached. Origin code only marks both blue and green channel
case as connected, but ignore other possible connected states. This one
trys to detect CRT by checking no channel attached case instead.

When the ideal error range can't be reached, this will safely use
a most closed one. Clean up some dumb codes in DPLL function too.
This fixes DPLL clock issue against one monitor at 1680x1050@60hz.

There is a problem in the quirk tables used by tpacpi_is_fw_known() and
tpacpi_check_outdated_fw(), which causes outdated BIOSes that are lacking
the EC firmware ID DMI field to never match.
This breaks module loading on, e.g. a T23 with outdated BIOS, and the
module will refuse to load unless the "force_load=1" parameter is given.
Fix the quirk tables so that they can also match the outdated BIOSes,
which in turn will both fix the module loading, and also warn the user
that he is using outdated firmware and should upgrade.
This fixes a serious regression, introduced by commit
e675abafcc0df38125e6e94a9ba91c92fe774f52, "thinkpad-acpi: be more strict
when detecting a ThinkPad".

_BIF was returning buffer instead of a string since day 1 of ACPI.
Adding a warning for that is noble, but people don't like

When the framebuffer driver does not publish detailed timing information
for the current video mode, the correct value for the pixclock field is
zero, not -1.
Since pixclock is actually unsigned, the value -1 would be interpreted
as 4294967295 picoseconds (i.e., about 4 milliseconds) by
register_framebuffer() and userspace programs.
This patch allows X.org's fbdev driver to work.

Some architectures compute ->vm_page_prot depending on ->vm_flags, so we
need to update the protections after adjusting the flags.
AFAIK this only affects running X under Xen; without this patch you get
lots of coloured blobs on the screen, or maybe a complete lockup. Or
anything really.
But that still depends on lots of out-of-tree stuff, so I don't think
there are any consequences for anyone else. But it is wrong in principle.

On broken EDID we were reporting vga connector to be disconnected
even if ddc probe did found a monitor. This patch report that the
connector is connected on such case. This allow drm to add a fail
safe mode (800x600 at the time of this patch) thus user can boot
and later add a mode which match its monitor capabilities.

unused_nodes modification needs to be protected by unused_lock spinlock.
Here is an example of an usage where there is no such protection without
this patch.
Process 1: 1-drm_mm_pre_get(this function modify unused_nodes list)
2-spin_lock(spinlock protecting mm struct)
3-drm_mm_put_block(this function might modify unused_nodes
list but doesn't protect modification with unused_lock)
4-spin_unlock(spinlock protecting mm struct)
Process2: 1-drm_mm_pre_get(this function modify unused_nodes list)
At this point Process1 & Process2 might both be doing modification to
unused_nodes list. This patch add unused_lock protection into
drm_mm_put_block to avoid such issue.

RS400,RC410,RS480 chipset seems to report a lot of false positive
with load detect on TV output. We haven't yet found a way to make
load detect reliable on those chipset, thus just disable it for TV
output. Would avoid user to experience phantom screen because X
believe there is a monitor connected to the TV output.

This fixes RH bugzilla #527874.
On resume the atom posting wasn't working, however vbe posting was
going fine, after 2 weeks over irc, and 8 hrs with the hardware,
I tracked it down to the memory device table and it access the MC
registers via IIO, it appears the rv515 atom iio table might not
be fully functional, so adding a readback before doing a write
either provides enough delay to make things resume correctly.
