Alexander Usyskin 8f642155c5 mei: drop unused hw dependent fw status functions
We introduced unified FW status function in patch
mei: add per device configuration (lkml.org/lkml/2014/5/12/607)

This change made hw_ops functions unused and obsolete
therefore we remove these functions from source code.

Himangi Saraogi 4734e39064 misc: bh1770glc: Use managed functions
This patch introduces the use of managed interfaces like devm_kzalloc,
devm_regulator_bulk_get and does away with the functions to free the
allocated memory in the probe and remove functions. Also, some labels
are removed and renamed to preserve the ordering.

Alexander Usyskin d5d83f8abe mei: don't schedule suspend in pm idle
Calling pm_schedule_suspend from the runtime pm idle callback
may reschedule existing timer, thus in case of frequent runtime
rpm idle call the suspend maybe starved.
Instead we call pm_runtime_autosuspend which is checking if the
timer is already charged.

An example is monitoring device pci config space.
Pci config sysfs handlers calls pci_config_pm_runtime_put/get
helpers which in turns calls to device idle callback

Alexander Usyskin 3e37ebb718 mei: reset client connection state on timeout
On connection timeout we leave the connecting client in
connecting state. Since a new connection is stalled till
previous connection is completed in this case no new connection
is possible till the user space does release the file handle.
Therefore on timeout we move the client to disconnected state.

Helge Deller ab8a261ba5 parisc: fix fanotify_mark() syscall on 32bit compat kernel
On parisc we can not use the existing compat implementation for fanotify_mark()
because for the 64bit mask parameter the higher and lower 32bits are ordered
differently than what the compat function expects from big endian
architectures.

Specifically:
It finally turned out, that on hppa we end up with different assignments
of parameters to kernel arguments depending on if we call the glibc
wrapper function
 int fanotify_mark (int __fanotify_fd, unsigned int __flags,
                    uint64_t __mask, int __dfd, const char *__pathname);
or directly calling the syscall manually
 syscall(__NR_fanotify_mark, ...)

Reason is, that the syscall() function is implemented as C-function and
because we now have the sysno as first parameter in front of the other
parameters the compiler will unexpectedly add an empty paramenter in
front of the u64 value to ensure the correct calling alignment for 64bit
values.
This means, on hppa you can't simply use syscall() to call the kernel
fanotify_mark() function directly, but you have to use the glibc
function instead.

This patch fixes the kernel in the hppa-arch specifc coding to adjust
the parameters in a way as if userspace calls the glibc wrapper function
fanotify_mark().

- update the parent for Auudss clock because kernel will be hang
   during late boot if the parent clock is disabled in bootloader.
 - enable clk handing in power domain because while power domain
   on/off, its regarding clock source will be reset and it causes
   a problem so need to handle it.
 - add mux clocks to be used by power domain for exynos5420-mfc
   during power domain on/off and property in device tree also.
 - register cpuidle only for exynos4210 and exynos5250 because a
   system failure will be happened on other exynos SoCs.

Dell kernel driver dell-smo8800 provides same freefall interface as hp_accel so
program hpfall.c works also on Dell laptops. So rename it to freefall.c.

Dell driver does not provide hp::hddprotect led so make sure that freefall.c
works also if hp::hddprotect does not exist in sysfs.

Additionally write info to syslog.

Horia Geanta cbb4d3e651 scripts/kernel-doc: handle object-like macros
Object-like macros are different than function-like macros:
https://gcc.gnu.org/onlinedocs/cpp/Object-like-Macros.html
https://gcc.gnu.org/onlinedocs/cpp/Function-like-Macros.html

They are not parsed correctly, generating invalid intermediate
files (xmls) for cases like:
    #define BIT_MASK    (0xFF << BIT_SHIFT)
where "OxFF <<" is considered to be parameter type.

When parsing, we can differentiate beween these two types of macros by
checking whether there is at least one whitespace b/w "#define" and
first opening parenthesis.

The paragraph on mcelog currently describes kernel v2.6.31. In that
kernel the mce code (for i386, that is) was in transition. Ever since
v2.6.32 the situation is much simpler (eg, mcelog is now needed to
process events on almost all x86 machines, i386 and x86-64). Since this
"document is designed to provide a list of the minimum levels of
software necessary to run the 3.0 kernels" let's just describe that
situation.

Siva Yerramreddy 95b4ecbf75 dma: MIC X100 DMA Driver
This patch implements DMA Engine API for DMA controller on MIC X100
Coprocessors. DMA h/w is shared between host and card s/w.
Channels 0 to 3 are used by host and 4 to 7 are used by card.
Since the DMA device doesn't show up as PCIe device, a virtual bus called mic
bus is created and virtual devices are added on that bus to follow device model.
Allowed dma transfer directions are host to card, card to host and card to card.

This MIC virtual bus driver takes the responsibility of creating all
the virtual devices connected to the PCIe device on the host and the
platform device on the card. The MIC bus hardware operations provide
a way to abstract certain hardware details from the base physical devices.
Examples of devices added on the MIC virtual bus include host DMA and card DMA.
This abstraction enables using a common DMA driver on host and card.

If probe fails then we need to call pm_runtime_disable() to balance
out the previous pm_runtime_enable() call. Else it will cause
unbalanced pm_runtime_enable() call in the succeding probe call.

This anomaly was observed when the call to devm_phy_create() failed
with -EPROBE_DEFER.

Balance out the pm_runtime_enable() call in .remove() as well.
