2010-04-09drm/nv50: another dodgy DP hackBen Skeggs
Allows *some* DP cards to keep working in some corner cases that most people shouldn't hit. I hit it all the time with development, so this can stay for now. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2010-04-09drm/nv50: punt hotplug irq handling out to workqueueBen Skeggs
On DP outputs we'll likely end up running vbios init tables here, which may sleep. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2010-04-09drm/nv50: preserve an unknown SOR_MODECTRL value for DP encodersBen Skeggs
This value interacts with some registers we don't currently know how to program properly ourselves. The default of 5 that we were using matches what the VBIOS on early DP cards do, but later ones use 6, which would cause nouveau to program an incorrect mode on these chips.

2010-04-09drm/nv40: rework lvds table parsingBen Skeggs
All indications seem to be that the version 0x30 table should be handled the same way as 0x40 (as used on G80), at least for the parts that we currently try use. This commit cleans up the parsing to make it clearer about what we're actually trying to achieve, and unifies the 0x30/0x40 parsing. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2010-04-09drm/nouveau: detect vram amount once, and save the valueBen Skeggs
As opposed to repeatedly reading the amount back from the GPU every time we need to know the VRAM size. We should now fail to load gracefully on detecting no VRAM, rather than something potentially messy happening. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2010-04-08libata: Fix accesses at LBA28 boundary (old bug, but nasty) (v2)Mark Lord
Most drives from Seagate, Hitachi, and possibly other brands, do not allow LBA28 access to sector number 0x0fffffff (2^28 - 1). So instead use LBA48 for such accesses. This bug could bite a lot of systems, especially when the user has taken care to align partitions to 4KB boundaries. On misaligned systems, it is less likely to be encountered, since a 4KB read would end at 0x10000000 rather than at 0x0fffffff.

2010-04-08ASoC: imx-ssi: Use a hrtimer in FIQ modeSascha Hauer
Using a regular timer results in poll times < 1 jiffie with small buffers, so we loaded the timer with the actual jiffie value. We can be more accurate using a hrtimer. Also, we have to call snd_pcm_period_elapsed after playing period_bytes and not runtime->period_size (which is in samples and not in bytes).

2010-04-08udf: potential integer overflowDan Carpenter
bloc->logicalBlockNum is unsigned so it's never less than zero. When I saw that, it made me worry that "bloc->logicalBlockNum + count" could overflow. That's why I changed the check for less than zero to an overflow check. (The test works because "count" is also unsigned.)

2010-04-08hvc_console: Fix race between hvc_close and hvc_removeAnton Blanchard
I don't claim to understand the tty layer, but it seems like hvc_open and hvc_close should be balanced in their kref reference counting. Right now we get a kref every call to hvc_open: if (hp->count++ > 0) { tty_kref_get(tty); <----- here spin_unlock_irqrestore(&hp->lock, flags); hvc_kick(); return 0; } /* else count == 0 */ tty->driver_data = hp; hp->tty = tty_kref_get(tty); <------ or here if hp->count was 0 But hvc_close has: tty_kref_get(tty); if (--hp->count == 0) { ... /* Put the ref obtained in hvc_open() */ tty_kref_put(tty); ... } tty_kref_put(tty); Since the outside kref get/put balance we only do a single kref_put when count reaches 0. The patch below changes things to call tty_kref_put once for every hvc_close call, and with that my machine boots fine.

2010-04-08virtio: disable multiport console support.Michael S. Tsirkin
Move MULTIPORT feature and related config changes out of exported headers, and disable the feature at runtime.

Tsirkin <mst@redhat.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2010-04-08virtio: console makes incorrect assumption about virtio APIRusty Russell
The get_buf() API sets the second arg to the number of bytes *written* by the other side; in this case it should be zero as these are output buffers. lguest gets this right (obviously kvm's console doesn't), resulting in continual buildup of console writes.

2010-04-08virtio: console: Fix early_put_chars usageFrançois Diakhaté
Currently early_put_chars is not used by virtio_console because it can only be used once a port has been found, at which point it's too late because it is no longer needed. This patch should fix it.

2010-04-07rwsem generic spinlock: use IRQ save/restore spinlocksKevin Hilman
rwsems can be used with IRQs disabled, particularily in early boot before IRQs are enabled. Currently the spin_unlock_irq() usage in the slow-patch will unconditionally enable interrupts and cause problems since interrupts are not yet initialized or enabled. This patch uses save/restore versions of IRQ spinlocks in the slowpath to ensure interrupts are not unintentionally disabled.

When manually assigning the path records to use for a connection, save the number of paths that were set. Otherwise, checks against num_path will show 0, even though path record data is available. This was discovered by manually setting the path records from user space, then querying the kernel to see if the correct path records were assigned, only to discover that the kernel returned 0 path records to the query.
