Pull ARM SoC fixes from Olof Johansson: "This is a batch of fixes for arm-soc platforms, most of it is for OMAP but there are others too (i.MX, Tegra, ep93xx). Fixes warnings, some broken platforms and drivers, etc. A bit all over the map really." There was some concern about commit 68136b10 ("RM: sunxi: Change device tree naming scheme for sunxi"), but Tony says: "Looks like that's trivial to fix as needed, no need to rebuild the branch to fix that AFAIK. The fix can be done once Olof is available online again.

2012-12-20dma-buf: might_sleep() in dma_buf_unmap_attachment()Rob Clark1-0/+2
We never really clarified if unmap could be done in atomic context. But since mapping might require sleeping, this implies mutex in use to synchronize mapping/unmapping, so unmap could sleep as well. Add a might_sleep() to clarify this.

Fix regression introduced by 85b144f860176 "drm/ttm: call ttm_bo_cleanup_refs with reservation and lru lock held, v3" Slowpath ttm_bo_cleanup_refs_and_unlock accidentally tried to increase refcount on &bo->sync_obj instead of bo->sync_obj. The compiler didn't complain since sync_obj_ref takes a void pointer, so it was still valid c.

However this shows that the code isn't very robust and future changes could easily introduce a buffer overflow. So let's add a safety check to prevent that and make smatch happy.

2012-12-19ksz884x: fix receive polling race conditionLennert Buytenhek1-3/+9
The ksz884x driver does receive processing in a custom tasklet, and seems to be assuming that since it takes its private interface spinlock with spin_lock_irq(), it won't be running concurrently with its own interrupt handler, as it cannot be preempted by it, but since its interrupt handler doesn't do any locking whatsoever, the receive processing tasklet and interrupt handler can end up running concurrently on different CPUs. As a result of this, the ksz884x receive path ends up locking up fairly easily, when the receive processing tasklet's reenabling of receive interrupts (due to it being done with polling the receive ring) races with the interrupt handler's disabling of receive interrupts (due to a new receive interrupt coming in) resulting in the receive interrupt being masked but the receive processing tasklet not being scheduled. Fix this by making the ksz884x interrupt handler take its private interface spinlock. This requires upgrading the spin_lock() in the transmit cleanup tasklet to a spin_lock_irq(), as otherwise the IRQ handler can preempt transmit cleanup and deadlock the system, but with those two changes, no more receive lockups have been observed.

2012-12-19of: Fix export of of_find_matching_node_and_match()Grant Likely1-1/+1
Commit 50c8af4cf9, "of: introduce for_each_matching_node_and_match()" renamed of_find_matching_node() to of_find_matching_node_and_match() and created a new static inline of_find_matching_node() wrapper around the new name. However, the change neglected to change the EXPORT_SYMBOL() reference causing build errors for modules. This patch fixes the EXPORT_SYMBOL() statement. Discovered on a PowerPC Efika build with the mpc52xx_uart driver being built as a module.
