I was curious why sys_kcmp wasn't working, which led me to the testcase.

dma-debug: new interfaces to debug dma mapping errors

Add dma-debug interface debug_dma_mapping_error() to debug drivers that
fail to check dma mapping errors on addresses returned by dma_map_single()
and dma_map_page() interfaces.  This interface clears a flag set by
debug_dma_map_page() to indicate that dma_mapping_error() has been called
by the driver.  When driver does unmap, debug_dma_unmap() checks the flag
and if this flag is still set, prints warning message that includes call
trace that leads up to the unmap.  This interface can be called from
dma_mapping_error() routines to enable dma mapping error check debugging.

Tested: Intel iommu and swiotlb (iommu=soft) on x86-64 with
        CONFIG_DMA_API_DEBUG enabled and disabled.

random: make it possible to enable debugging without rebuild

The module parameter that turns debugging mode (which basically means
printing a few extra lines during runtime) is in '#if 0' block.  Forcing
everyone who would like to see how entropy is behaving on his system to
rebuild seems to be a little bit too harsh.

If we were concerned about speed, we could potentially turn 'debug' into a
static key, but I don't think it's necessary.

ipc/sem.c: alternatives to preempt_disable()

ipc/sem.c uses a custom wakeup scheme that relies on preempt_disable().
On -RT, this causes increased latencies and debug warnings.

The patch adds two additional schemes:
- one built around a completion - could be better for -RT kernels
- one built around a spinlock - unfortunately it's broken
- and the current one

My preferred solution would be the spinlock implementation: RT would use
premptible spinlocks, mainline normal spinlocks.  Thus both get the
optimal implementation without any special code in ipc/sem.c.
Unfortunately, I don't see how it could be fixed.

procfs: add VmFlags field in smaps output

During c/r sessions we've found that there is no way at the moment to
fetch some VMA associated flags, such as mlock() and madvise().

This leads us to a problem -- we don't know if we should call for mlock()
and/or madvise() after restore on the vma area we're bringing back to
life.

This patch intorduces a new field into "smaps" output called VmFlags,
where all set flags associated with the particular VMA is shown as two
letter mnemonics.

[ Strictly speaking for c/r we only need mlock/madvise bits but it has been
  said that providing just a few flags looks somehow inconsistent.  So all
  flags are here now. ]

This feature is made available on CONFIG_CHECKPOINT_RESTORE=n kernels, as
other applications may start to use these fields.

The data is encoded in a somewhat awkward two letters mnemonic form, to
encourage userspace to be prepared for fields being added or removed in
the future.

proc: don't show nonexistent capabilities

Without this patch it is really hard to interpret a bounding set, if
CAP_LAST_CAP is unknown for a current kernel.

Non-existant capabilities can not be deleted from a bounding set with help
of prctl.

E.g.: Here are two examples without/with this patch.
CapBnd: ffffffe0fdecffff
CapBnd: 00000000fdecffff

I suggest to hide non-existent capabilities. Here is two reasons.
* It's logically and easier for using.
* It helps to checkpoint-restore capabilities of tasks, because tasks
can be restored on another kernel, where CAP_LAST_CAP is bigger.

fat: modify nfs mount option

This patchset eliminates the client side ESTALE errors when a FAT
partition exported over NFS has its dentries evicted from the cache.

One of the reasons for this error is lack of permanent inode numbers on
FAT which makes it difficult to construct persistent file handles.  This
can be overcome by using fat_encode_fh() that include i_pos in file
handle.

Once the i_pos is available, it is only a matter of reading the directory
entries from the disk clusters to locate the matching entry and rebuild
the corresponding inode.

We reached the conclusion support stable inode's read-only export first
after discussing with OGAWA and Bruce.  And will make it writable with
some operation(unlink and rename) limitation next time.

This patch:

Provide two possible values 'stale_rw' and 'nostale_ro' for the -o nfs
mount option.  The first one allows all file operations but does not
reduce ESTALE errors on memory constrained systems.  The second one
eliminates ESTALE errors but mounts the filesystem as read-only.  Not
specifying a value defaults to 'stale_rw'.

user_info and finder_info fields as for file (struct hfsplus_cat_file) as
for folder (struct hfsplus_cat_folder).  Moreover, current mainline
implementation of hfsplus file system driver doesn't support special
metadata file - attributes tree.

Mac OS X 10.4 and later support extended attributes by making use of the
HFS+ filesystem Attributes file B*-tree feature which allows for named
forks.  Mac OS X supports only inline extended attributes, limiting their
size to 3802 bytes.  Any regular file may have a list of extended
attributes.  HFS+ supports an arbitrary number of named forks.  Each
attribute is denoted by a name and the associated data.  The name is a
null-terminated Unicode string.  It is possible to list, to get, to set,
and to remove extended attributes from files or directories.

It exists some peculiarity during getting of extended attributes list by
means of getfattr utility.  The getfattr utility expects prefix "user."
before any extended attribute's name.  So, it ignores any names that don't
contained such prefix.  Such behavior of getfattr utility results in
unexpected empty output of extended attributes list even in the case when
file (or folder) contains extended attributes.  It needs to use empty
string as regular expression pattern for names matching (getfattr
--match="").

For support of extended attributes in HFS+:

1. It was added necessary on-disk layout declarations related to
   Attributes tree into hfsplus_raw.h file.

2. It was added attributes.c file with implementation of functionality
   of manipulation by records in Attributes tree.

3. It was reworked hfsplus_listxattr, hfsplus_getxattr,
   hfsplus_setxattr functions in ioctl.c.  Moreover, it was added
   hfsplus_removexattr method.

This patch:

Add all neccessary on-disk layout declarations related to attributes
file.

rtc: omap: add runtime pm support

OMAP1 RTC driver is used in multiple devices like, OMAPL138 and AM33XX.
Driver currently doesn't handle any clocks, which may be right for OMAP1
architecture but in case of AM33XX, the clock/module needs to be enabled
in order to access the registers.

So convert this driver to runtime pm, which internally handles rest.

rtc: omap: kicker mechanism support

OMAP RTC IP can have kicker feature.  This prevents spurious writes to
register.  To write to registers kicker lock has to be released.
Procedure to do it as follows,

1. write to kick0 register, 0x83e70b13
2. write to kick1 register, 0x95a4f1e0

Writing value other than 0x83e70b13 to kick0 enables write locking, more
details about kicker mechanism can be found in section 20.3.3.5.3 of
AM335X TRM @www.ti.com/am335x

Here id table information is added and is used to distinguish those that
require kicker handling and the ones that doesn't need it.  There are more
features in the newer IP's compared to legacy ones other than kicker,
which driver currently doesn't handle, supporting additional features
would be easier with the addition of id table.

Older IP (of OMAP1) doesn't have revision register as per TRM, so revision
register can't be relied always to find features, hence id table is being
used.

While at it, replace __raw_writeb/__raw_readb with writeb/readb; this
driver is used on ARMv7 (AM335X SoC)

The reason for a single patch covering powerpc, tile, sparc and arm64 is
to keep it bisectable, otherwise kernel building may fail with mismatched

The mutex for accessing lp855x registers is used in case of the user-space
interaction.  When the brightness is changed via sysfs, the mutex is

drivers/video/backlight/lp855x_bl.c: use generic PWM functions

The LP855x family devices support the PWM input for the backlight control.
 Period of the PWM is configurable in the platform side.  Platform
specific functions are unnecessary anymore because generic PWM functions
are used inside the driver.

(PWM input mode)
To set the brightness, new lp855x_pwm_ctrl() is used.
If a PWM device is not allocated, devm_pwm_get() is called.
The PWM consumer name is from the chip name such as 'lp8550' and 'lp8556'.
To get the brightness value, no additional handling is required.
Just the value of 'props.brightness' is returned.

If the PWM driver is not ready while initializing the LP855x driver, it's
OK.  The PWM device can be retrieved later, when the brightness value is
changed.

Documentation is updated with an example.
