Reading 64-bits register was not working because we inverted the steps
between reading the lower 32-bits of the register and reading the upper
32-bits. Swapping these operations is how the HW guarantees that 64-bits
reads are latched correctly. We only have a handful of 64-bits registers
for now, mostly MIB counters, so the imapct is low.

The ltpc driver is rather outdated and does not get built on most
platforms because it requires the ISA_DMA_API symbol. However
there are some ARM platforms that have ISA_DMA_API but no virt_to_bus,
and they get this build error when enabling the ltpc driver.
drivers/net/appletalk/ltpc.c: In function 'handlefc':
drivers/net/appletalk/ltpc.c:380:2: error: implicit declaration of function 'virt_to_bus' [-Werror=implicit-function-declaration]

The smc91x driver tries to support multiple platforms at compile
time, but they are mutually exclusive at runtime, and not clearly
defined.
Trying to build for CONFIG_SA1100_ASSABET without CONFIG_ASSABET_NEPONSET
results in this link error:
drivers/built-in.o: In function `smc_drv_probe':
:(.text+0x33310c): undefined reference to `neponset_ncr_frob'
since the neponset_ncr_set function is not defined otherwise.
Similarly, building for both CONFIG_SA1100_ASSABET and CONFIG_SA1100_PLEB
results in a different build error:
smsc/smc91x.c: In function 'smc_drv_probe':
smsc/smc91x.c:2299:2: error: implicit declaration of function 'neponset_ncr_set' [-Werror=implicit-function-declaration]
neponset_ncr_set(NCR_ENET_OSC_EN);

smsc/smc91x.c:2299:19: error: 'NCR_ENET_OSC_EN' undeclared (first use in this function)
neponset_ncr_set(NCR_ENET_OSC_EN);
^
This is an attempt to fix the call site responsible for both
errors, making sure we call the function exactly when the driver
is actually trying to run on the assabet/neponset machine. With
this patch, I no longer see randconfig build errors in this file.

If both promisc and allmulti are set, promisc should trump allmulti and
disable the MAC filter; otherwise, the interface is not really promisc.
Previously, this code checked IFF_ALLMULTI prior to and without regard for
IFF_PROMISC; if both were set, only multicast and direct unicast traffic
would make it through the filter.

phy_init_eee uses phy_find_setting(phydev->speed, phydev->duplex)
to find a valid entry in the settings array for the given speed
and duplex value. For full duplex 1000baseT, this will return
the first matching entry, which is the entry for 1000baseKX_Full.
If the phy eee does not support 1000baseKX_Full, this entry will not
match, causing phy_init_eee to fail for no good reason.

Commit a7854487cd7128a30a7f4f5259de9f67d5efb95f:
md: When RAID5 is dirty, force reconstruct-write instead of read-modify-write.
Causes an RCW cycle to be forced even when the array is degraded.
A degraded array cannot support RCW as that requires reading all data
blocks, and one may be missing.
Forcing an RCW when it is not possible causes a live-lock and the code
spins, repeatedly deciding to do something that cannot succeed.
So change the condition to only force RCW on non-degraded arrays.

Till now suspend-to-idle has not been able to save much more energy
than runtime PM because of timer interrupts that periodically bring
CPUs out of idle while they are waiting for a wakeup interrupt. Of
course, the timer interrupts are not wakeup ones, so the handling of
them can be deferred until a real wakeup interrupt happens, but at
the same time we don't want to mass-expire timers at that point.
The solution is to suspend the entire timekeeping when the last CPU
is entering an idle state and resume it when the first CPU goes out
of idle. That has to be done with care, though, so as to avoid
accessing suspended clocksources etc. end we need extra support
from idle drivers for that.
This series of commits adds support for quiescing timers during
suspend-to-idle and adds the requisite callbacks to intel_idle
and the ACPI cpuidle driver.

The dw_wdt_set_top() function takes in a value in seconds. In
dw_wdt_open() we were calling it with a value that's supposed to
represent the maximum value programmed into the "top" register with a
comment saying that we were trying to set the watchdog to its maximum
value. Instead we ended up setting the watchdog to ~15 seconds.
Let's fix this. However, setting things to the "max" gives me an 86
second watchdog in the system I'm looking at. 86 seconds feels a
little too long. We'll explicitly choose 30 seconds as a more
reasonable value.
NOTE: Ideally this driver should be transitioned to be a real watchdog
driver. Then we could use "watchdog_init_timeout" and let the timeout
be specified in a number of ways (device tree, module parameter, etc).
This patch should be considered a bit of a stopgap solution.

On some dw_wdt implementations the "top" register may be initted to 0
at bootup. In such a case, each "pat" of the watchdog will reset the
timer to 0xffff. That's pretty short.
The input clock of the wdt can be any of a wide range of values. On
an rk3288 system, I've seen the wdt clock be 24.75 MHz. That means
each tick is ~40ns and we'll count to 0xffff in ~2.6ms.
Because of the above two facts, it's a really good idea to pat the
watchdog after initting the "top" register properly and before
enabling the watchdog. If you don't then there's no way we'll get the
next heartbeat in time.
Jisheng Zhang fixed this problem on some dw_wdt versions by using the
TOP_INIT feature. However, the dw_wdt on rk3288 doesn't have TOP_INIT
so it's a good idea to also pat the watchdog manually.

Merge tag 'cleanup-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC cleanups from Olof Johansson:
"This is a good healthy set of various code removals. Total net delta
is 8100 lines removed.
Among the larger cleanups are:
- Removal of old Samsung S3C DMA infrastructure by Arnd
- Removal of the non-DT version of the 'lager' board by Magnus Damm
- General stale code removal on OMAP and Davinci by Rickard Strandqvist
- Removal of non-DT support on am3517 platforms by Tony Lindgren
... plus several other cleanups of various platforms across the board"

- A few things which were awaiting merges from linux-next:
- rtc
- ocfs2
- misc others
- Willy's "dax" feature: direct fs access to memory (mainly NV-DIMMs)
which isn't backed by pageframes.
* emailed patches from Andrew Morton <akpm@linux-foundation.org>: (37 commits)

This adds a driver for the Dallas/Maxim DS1685-family of RTC chips. It
supports the DS1685/DS1687, DS1688/DS1691, DS1689/DS1693, DS17285/DS17287,
DS17485/DS17487, and DS17885/DS17887 RTC chips. These chips are commonly
found in SGI O2 and SGI Octane systems. It was originally derived from a
driver patch submitted by Matthias Fuchs many years ago for use in
EPPC-405-UC modules, which also used these RTCs. In addition to the
time-keeping functions, this RTC also handles the shutdown mechanism of
the O2 and Octane and acts as a partial NVRAM for the boot PROMS in these
systems.
Verified on both an SGI O2 and an SGI Octane.

Since this is relating to FS_XIP, not KERNEL_XIP, it should be called
DAX instead of XIP.

"isil" and "isl" prefixes are used at various locations inside the kernel
to reference Intersil corporation. This patch is part of a series fixing
those locations were "isl" is used in compatible strings to use the now
expected "isil" prefix instead (NASDAQ symbol for Intersil and most used
version). The old compatible string is kept for backward compatibility.
