_set_gpio_triggering uses read-modify-write on bank registers,
lock bank->lock around all calls to it to prevent register
corruption if two cpus access gpios in the same bank at the
same time.

Setting the IRQWAKEN bit was overwriting previous IRQWAKEN bits,
causing only the last bit set to take effect, resulting in lost
wakeups when the GPIO controller is in idle.
Replace direct writes to IRQWAKEN with MOD_REG_BIT calls to
perform a read-modify-write on the register.

The S3C_GPIO_PULL_UP macro value incorrectly maps to a reserved setting of GPIO
pull up/down registers on Exynos4 platform. Fix this incorrect mapping by adding

The find_next_zero_bit() is called with the from and to arguments in the
wrong order. This results in the function always returning 0, and all
media devices being registered with minor 0. Furthermore, mdev->minor is
then used before being assigned with the find_next_zero_bit() return
value. This really makes sure we'll always use minor 0.
Fix this and let the system support more than one media device.

Two ivtv_msleep_timeout() calls are incorrectly flagged as interruptable. The
first is in the init sequence for a capture and is required for stable
hardware setup. The second is at the end of the capture and used to handle the
last data transfer. Failure to wait for this last transfer can result in stale
data being read at the start of the next capture.

On my x86_64 system with >4GB of ram and swiotlb instead of
a hardware iommu (because I have a VIA chipset), the call
to pci_set_dma_mask (see below) with 40bits returns an error.
But it seems that the radeon driver is designed to have
need_dma32 = true exactly if pci_set_dma_mask is called
with 32 bits and false if it is called with 40 bits.
I have read somewhere that the default are 32 bits. So if the
call fails I suppose that need_dma32 should be set to true.
And indeed the patch fixes the problem I have had before
and which I had described here:

Wierdly the kms parser never initialised the family, it wasn't really used

The flush_to_ldisc() work entry has special logic to notice when it has
seen the original tail of the data queue, and it avoids continuing the
flush if it sees that _original_ tail rather than the current tail.
This logic can trigger in case somebody is constantly adding new data to
the tty while the flushing is active - and the intent is to avoid
excessive CPU usage while flushing the tty, especially as we used to do
this from a softirq context which made it non-preemptible.
However, since we no longer re-arm the work-queue from within itself
(because that causes other trouble: see commit a5660b41af6a "tty: fix
endless work loop when the buffer fills up"), this just leads to
possible hung tty's (most easily seen in SMP and with a test-program
that floods a pty with data - nobody seems to have reported this for any
real-life situation yet).
And since the workqueue isn't done from timers and softirq's any more,
it's doubtful whether the CPU useage issue is really relevant any more.
So just remove the logic entirely, and see if anybody ever notices.
Alternatively, we might want to re-introduce the "re-arm the work" for
just this case, but then we'd have to re-introduce the delayed work
model or some explicit timer, which really doesn't seem worth it for
this.

A tile on gen2 has a size of 2kb, stride of 128 bytes and 16 rows.
Userspace was broken and assumed 8 rows. Chris Wilson noted that the
kernel unfortunately can't reliable check that because libdrm rounds
up the size to the next bucket.

Rather than proceed on and silently return false by default, mention why
we rejected the presence of an EDID as implying the presence of a VGA
monitor. (The question arises whether there is a broken EDID which falsely
reports a digital connection when attached by VGA.)

The computation of the first-level watermarks for g4x and gen5+ are
based on the same algorithm, so we can refactor those code paths to
use a single function.
Note that g4x_compute_wm0 takes a 'plane' argument while
ironlake_compute_wm0 took a 'pipe' argument. Both should have used a
'plane' argument, so this patch fixes that as well (not that it caused
a problem; ironlake always uses pipe == plane).
