Flag irq_remapping_enabled is only set by intel_enable_irq_remapping(),
which is called after detect_intel_iommu(). So moving pr_info() from
detect_intel_iommu() to intel_enable_irq_remapping(), which also
slightly simplifies implementation.

In Intel IOMMU driver, it calculate page table level from adjusted guest
address width as 'level = (agaw - 30) / 9', which assumes (agaw -30)
could be divided by 9. On the other hand, 64bit is a valid agaw and
(64 - 30) can't be divided by 9, so it needs special handling.
This patch enhances Intel IOMMU driver to correctly handle 64bit agaw.
It's mainly for code readability because there's no hardware supporting
64bit agaw yet.

Currently Intel interrupt remapping drivers uses the "present" flag bit
in remapping entry to track whether an entry is allocated or not.
It works as follow:
1) allocate a remapping entry and set its "present" flag bit to 1
2) compose other fields for the entry
3) update the remapping entry with the composed value
The remapping hardware may access the entry between step 1 and step 3,
which then observers an entry with the "present" flag set but random
values in all other fields.
This patch introduces a dedicated bitmap to track remapping entry
allocation status instead of sharing the "present" flag with hardware,
thus eliminate the race window. It also simplifies the implementation.

After commit 88f718e3fa
"ARM: pxa: delete the custom GPIO header" a compilation
error was introduced in the PXA25x gadget driver.
An attempt to fix the problem was made in
commit b144e4ab1e
"usb: gadget: fix pxa25x compilation problems"
by explictly stating the driver needs the <mach/hardware.h>
header, which solved the compilation for a few boards,
such as the pxa255-idp and its defconfig.
However the Lubbock board has this special clause in
drivers/usb/gadget/pxa25x_udc.c:
This include file has an implicit dependency on
<mach/irqs.h> having been included before <mach/lubbock.h>
was included.
Before commit 88f718e3fa
"ARM: pxa: delete the custom GPIO header" this implicit
dependency for the pxa25x_udc compile on the Lubbock was
satisfied by <linux/gpio.h> implicitly including
<mach/gpio.h> which was in turn including <mach/irqs.h>,
apart from the earlier added <mach/hardware.h>.
Fix this by having the PXA25x <mach/lubbock.h> explicitly
include <mach/irqs.h>.

Looks like the LCD panel on LDP has been broken quite a while, and
recently got fixed by commit 0b2aa8bed3 (gpio: twl4030: Fix regression
for twl gpio output). However, there's still an issue left where the panel
backlight does not come on if the LCD drivers are built into the
kernel.
Fix the issue by registering the DPI LCD panel only after the twl4030
GPIO has probed.

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.

Pull libata fixes from Tejun Heo:
"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
M500 SSDs which otherwise suffers data corruption"

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.
