Commit 4dcfa60071 ("ARM: DMA-API: better
handing of DMA masks for coherent allocations") added an additional
check to the coherent DMA mask that results in an error when the mask is
larger than what dma_addr_t can address.
Set the LCDC coherent DMA mask to DMA_BIT_MASK(32) instead of ~0 to fix
the problem.

Commit 7d7e1eb (ARM: OMAP2+: Prepare for irqs.h removal) and commit
ec2c082 (ARM: OMAP2+: Remove hardcoded IRQs and enable SPARSE_IRQ)
updated the way interrupts for OMAP2/3 devices are defined in the
HWMOD data structures to being an index plus a fixed offset (defined
by OMAP_INTC_START).
Couple of irqs in the OMAP2/3 hwmod data were misconfigured completely
as they were missing this OMAP_INTC_START relative offset. Add this
offset back to fix the incorrect irq data for the following modules:
OMAP2 - GPMC, RNG
OMAP3 - GPMC, ISP MMU & IVA MMU

With commit '7dedd34: ARM: OMAP2+: hwmod: Fix a crash in _setup_reset() with
DEBUG_LL' we moved from parsing cmdline to identify uart used for earlycon
to using the requsite hwmod CONFIG_DEBUG_OMAPxUARTy FLAGS.
On DRA7 though, we seem to be missing this flag, and atleast on the DRA7 EVM
where we use uart1 for console, boot fails with DEBUG_LL enabled.

Fill in asic family specific versions rather than
using the generic version. This lets us handle asic
specific differences more easily. In this case, we
disable sw swapping of the rtpr writeback value on
r6xx+ since the hw does it for us. Fixes bogus
rptr readback on BE systems.

We need more control over the ordering of dpm init with
respect to the rest of the asic. Specifically, the SMC
has to be initialized before the rlc and cg/pg. The pm
code currently initializes late in the driver, but we need
it to happen much earlier so move pm handling into the asic
specific callbacks.
This makes dpm more reliable and makes clockgating work
properly on CIK parts and should help on SI parts as well.

"There's one interseting commit - "libata, freezer: avoid block device
removal while system is frozen". It's an ugly hack working around a
deadlock condition between driver core resume and block layer device
removal paths through freezer which was made more reproducible by
writeback being converted to workqueue some releases ago. The bug has
nothing to do with libata but it's just an workaround which is easy to
backport. After discussion, Rafael and I seem to agree that we don't
really need kernel freezables - both kthread and workqueue. There are
few specific workqueues which constitute PM operations and require
freezing, which will be converted to use workqueue_set_max_active()
instead. All other kernel freezer uses are planned to be removed,
followed by the removal of kthread and workqueue freezer support,
hopefully.
Others are device-specific fixes. The most notable is the addition of
NO_NCQ_TRIM which is used to disable queued TRIM commands to Micro

selinux_setprocattr() does ptrace_parent(p) under task_lock(p),
but task_struct->alloc_lock doesn't pin ->parent or ->ptrace,
this looks confusing and triggers the "suspicious RCU usage"
warning because ptrace_parent() does rcu_dereference_check().
And in theory this is wrong, spin_lock()->preempt_disable()
doesn't necessarily imply rcu_read_lock() we need to access
the ->parent.
