Disabling CONFIG_BUG creates an insane amount of build warnings, which
makes it useless to check for building defconfigs to see if new
warnings show up.

exynos_pm_add_dev_to_genpd is used if one or more out of a large
number of Kconfig symbols are enabled. However the new
exynos_defconfig selects none of those, so the function becomes
unused. Marking it so lets the compiler automatically discard
it.

The EETI touchscreen asserts its IRQ line as soon as it has data in its
internal buffers. The line is automatically deasserted once all data has
been read via I2C. Hence, the driver has to monitor the GPIO line and
cannot simply rely on the interrupt handler reception.
In the current implementation of the driver, irq_to_gpio() is used to
determine the GPIO number from the i2c_client's IRQ value.
As irq_to_gpio() is not available on all platforms, this patch changes
this and makes the driver ignore the passed in IRQ. Instead, a GPIO is
added to the platform_data struct and gpio_to_irq is used to derive the
IRQ from that GPIO. If this fails, bail out. The driver is only able to
work in environments where the touchscreen GPIO can be mapped to an
IRQ.

Commit 3d55c29 "ARM: tegra: harmony: add regulator supply name and its
input supply" was supposed to fix all the problems with regulators on
Harmony. However, it appears that I only tested it when booting using
board files, not when booting using device tree. This change fixes two
problems with regulators when booting using device tree:
1) That patch only created the vdd_sys regulator when booting using a
board file. Since this is the root of the whole regulator tree, this
caused no regulators to successfully initialize when booting using
device tree. The registration of vdd_sys is moved to fix this.
2) When booting use DT, the regulator core sets has_full_constraints,
which in turn causes the core to turn off any regulators not marked
as always on. Some of the affected regulators are required for basic
system operation. To solve this, add always on constraints to all
relevant regulators. This doesn't affect booting using a board file
since nothing sets has_full_constraints in that case.

The native 31 bit and the compat behaviour for the mmap system calls differ:
In native 31 bit mode the passed in address for the mmap system call will be
unmodified passed to sys_mmap_pgoff().
In compat mode however the passed in address will be modified with
compat_ptr() which masks out the most significant bit.
The result is that in native 31 bit mode each mmap request (with MAP_FIXED)
will fail where the most significat bit is set, while in compat mode it
may succeed.
This odd behaviour was introduced with d3815898 "[S390] mmap: add missing
compat_ptr conversion to both mmap compat syscalls".
To restore a consistent behaviour accross native and compat mode this
patch functionally reverts the above mentioned commit.

There are multiple errors in how sys_32_personality() handles personality
flags stored in top three bytes.
- directly comparing current->personality against PER_LINUX32 doesn't work
in cases when any of the personality flags stored in the top three bytes
are used.
- directly forcefully setting personality to PER_LINUX32 or PER_LINUX
discards any flags stored in the top three bytes
Fix the first one by properly using personality() macro to compare only
PER_MASK bytes.

The CONFIG_DEFAULT_MMAP_MIN_ADDR was set to 65536 in mxs_defconfig,
this caused severe breakage of userland applications since the upper
limit for ARM is 32768. By default CONFIG_DEFAULT_MMAP_MIN_ADDR is
set to 4096 and can also be changed via /proc/sys/vm/mmap_min_addr
if needed.
Quoting Russell King [1]:
"4096 is also fine for ARM too. There's not much point in having
defconfigs change it - that would just be pure noise in the config
files."
the CONFIG_DEFAULT_MMAP_MIN_ADDR can be removed from the defconfig
altogether.
This problem was introduced by commit cde7c41 (ARM: configs: add
defconfig for mach-mxs).

The imx5 common clock migration causes a regression with smsc911x

to be functional. In the new imx5 clock driver, there is no use count
incremented for the clock by enabling it, so the framework closes the
clock at late init time and makes EIM stop working then.

Coupled cpuidle was meant to merge for 3.5 through Len Brown's tree, but
didn't go in because the pull request ended up rejected. So it just got
merged, and we got this staged branch that enables the coupled cpuidle
code on OMAP.
With a stable git workflow from the other maintainer we could have staged
this earlier, but that wasn't the case so we have had to merge it late.
The alternative is to hold it off until 3.7 but given that the code is
well-isolated to OMAP and they are eager to see it go in, I didn't push
back hard in that direction.

The only way to write LATCHED registers to write LATCH_BIT to LATCH register,
that will latch COUNTER into LATCHED.e.g.

Writing values to LATCHED registers directly is useless at all.

When we release pages back during bootup:
Freeing 9d-100 pfn range: 99 pages freed
Freeing 9cf36-9d0d2 pfn range: 412 pages freed
Freeing 9f6bd-9f6bf pfn range: 2 pages freed

Freeing 9f7e0-9f7ff pfn range: 31 pages freed
Freeing 9f800-100000 pfn range: 395264 pages freed
Released 395979 pages of unused memory
We then try to populate those pages back. In the P2M tree however
the space for those leafs must be reserved - as such we use extend_brk.
We reserve 8MB of _brk space, which means we can fit over
1048576 PFNs - which is more than we should ever need.
Without this, on certain compilation of the kernel we would hit:
(XEN) domain_crash_sync called from entry.S

(XEN) Guest stack trace from rsp=ffffffff81801c98:
.. which is extend_brk hitting a BUG_ON.
Interestingly enough, most of the time we are not going to hit this
b/c the _brk space is quite large (v3.5):
ffffffff81a25000 B __brk_base
ffffffff81e43000 B __brk_limit
= ~4MB.
vs earlier kernels (with this back-ported), the space is smaller:
ffffffff81a25000 B __brk_base
ffffffff81a7b000 B __brk_limit
= 344 kBytes.
where we would certainly hit this and hit extend_brk.
Note that git commit c3d93f8801
(xen: populate correct number of pages when across mem boundary (v2))
exposed this bug).
[v1: Made it 8MB of _brk space instead of 4MB per Jan's suggestion]

There are multiple errors in how sys_sparc64_personality() handles
personality flags stored in top three bytes.
- directly comparing current->personality against PER_LINUX32 doesn't work
in cases when any of the personality flags stored in the top three bytes
are used.
- directly forcefully setting personality to PER_LINUX32 or PER_LINUX
discards any flags stored in the top three bytes
Fix the first one by properly using personality() macro to compare only
PER_MASK bytes.
Fix the second one by setting only the bits that should be set, instead of
overwriting the whole value.

Pull ARM DMA engine updates from Russell King:
"This looks scary at first glance, but what it is is:
- a rework of the sa11x0 DMA engine driver merged during the previous
cycle, to extract a common set of helper functions for DMA engine
implementations.
- conversion of amba-pl08x.c to use these helper functions.
- addition of OMAP DMA engine driver (using these helper functions),
and conversion of some of the OMAP DMA users to use DMA engine.
Nothing in the helper functions is ARM specific, so I hope that other
implementations can consolidate some of their code by making use of
these helpers.
This has been sitting in linux-next most of the merge cycle, and has
been tested by several OMAP folk. I've tested it on sa11x0 platforms,
and given it my best shot on my broken platforms which have the
amba-pl08x controller.
The last point is the addition to feature-removal-schedule.txt, which
will have a merge conflict. Between myself and TI, we're planning to
remove the old TI DMA implementation next year."

iret # clears ds, es due to mismatched rpl

Fix by avoiding the optimization on i386 and reloading ds, es on the

When a guest migrates to a new host, the system time difference from the
previous host is used in the updates to the kvmclock system time visible
to the guest, resulting in a continuation of correct kvmclock based guest
timekeeping.
The wall clock component of the kvmclock provided time is currently not
updated with this same time offset. Since the Linux guest caches the
wall clock based time, this discrepency is not noticed until the guest is
rebooted. After reboot the guest's time calculations are off.
This patch adjusts the wall clock by the kvmclock_offset, resulting in
correct guest time after a reboot.

to merge LEGACY, LINEAR and TREE mappings into a single system, but had
to back off from that after some last minute bugs. Instead it mainly
reorganizes the code and ensures that the reverse map gets populated
when the irq is mapped instead of the first time it is looked up.
Merging of the irq_domain types is deferred to v3.7

Some PMUs don't provide a full register set for their sample,
specifically 'advanced' PMUs like AMD IBS and Intel PEBS which provide
'better' than regular interrupt accuracy.
In this case we use the interrupt regs as basis and over-write some
fields (typically IP) with different information.
The perf core however uses user_mode() to distinguish user/kernel
samples, user_mode() relies on regs->cs. If the interrupt skid pushed
us over a boundary the new IP might not be in the same domain as the
interrupt.
Commit ce5c1fe9a9 ("perf/x86: Fix USER/KERNEL tagging of samples")
tried to fix this by making the perf core use kernel_ip(). This
however is wrong (TM), as pointed out by Linus, since it doesn't allow
for VM86 and non-zero based segments in IA32 mode.
Therefore, provide a new helper to set the regs->ip field,
set_linear_ip(), which massages the regs into a suitable state
assuming the provided IP is in fact a linear address.
Also modify perf_instruction_pointer() and perf_callchain_user() to
deal with segments base offsets.
