Switch all davinci boards supporting device tree to using the new
clocksource driver: remove the previous OF_TIMER_DECLARE() from
mach-davinci and select davinci-timer for ARCH_DAVINCI.

Boards from the dm* family rely on register offset definitions from
arch/arm/mach-davinci/include/mach/time.h. We'll be removing this file
soon, so move the required defines to davinci.h where the rest of such
constants live.

Hi Sekhar,
once the clocksource driver is in some upstream branch, you can pick this
series up - it contains the platform code necessary to use the new module.
Tested on da850-evm/lcdk, da830-evm and dm365-evm.

The cpufreq_online and the cpufreq_offline [un]register the driver as
a cooling device. This is done if the driver is flagged as a cooling
device in addition with a IS_ENABLED macro to compile out the branching

Group this test in a stub function added in the cpufreq header instead

Currently the function cpufreq_cooling_register() returns a cooling
device pointer which is used back as a pointer to call the function
cpufreq_cooling_unregister(). Even if it is correct, it would make
sense to not leak the structure inside a cpufreq driver and keep the
code thermal code self-enca

Ok for all, I can work more on refactoring if we agree on the basics.
For instance I can change the driver to use reg-names, same as

Tools such as vpnc try to flush routes when run inside network
namespaces by writing 1 into /proc/sys/net/ipv4/route/flush. This
currently does not work because flush is not enabled in non-initial

Since routes are per network namespace it is safe to enable

Allow fsinfo() to be used to query the filesystem attached to an fs_context
once a superblock has been created or if it comes from fspick().
The caller must specify AT_FSINFO_FROM_FSOPEN in the parameters and must
supply the fd from fsopen() as dfd and must set filename to NULL.
This is done with
Provide fsinfo() attributes that can be used to query a filesystem
parameter description. To do this, fsinfo() can be called on an
fs_context that doesn't yet have a superblock created and attached.
It can be obtained by doing, for example:
fd = fsopen("ext4", 0);

Implement parameter value retrieval with fsinfo() - akin to parsing

This allows all the parameters to be retrieved in one go with:

Each parameter comes as a pair of blobs wit

to see if a mount has changed its attributes or its children.
Future patches will:
(1) Provide this value through fsinfo() attributes.
(2) Hook into the notify_mount() function to provide a notification
interface
Introduce a non-repeating system-unique superblock ID that can be used to
tag superblock notification messages. The ID is time-based to make it
harder to use it as a covert communications channel.
Make it so that this ID can be fetched by the fsinfo() system call.

Latest -next fails to boot on POWER9 PowerVM LPAR due to RCU stalls.
This problem was introduced with next-20190620 (dc636f5d78).
next-20190619 was last good kernel.
Reverting following commit allows the kernel to boot.

Allow the fsinfo() syscall to look up a mount object by ID rather than by
pathname. This is necessary as there can be multiple mounts stacked up at
the same pathname and there's no way to look through them otherwise.
This is done by passing AT_FSINFO_MOUNTID_PATH to fsinfo() in the
parameters and

Implement LSM parameter value retrieval with fsinfo() - akin to parsing
/proc/mounts. This allows all the LSM parameters to be retrieved in one go
with:
struct fsinfo_params params = {
.request= FSINFO_ATTR_LSM_PARAMETER,
};
The format is a blob containing

Allow mount information, including information about the topology tree to
be queried with the fsinfo() system call. Usage of AT_FSINFO_MOUNTID_PATH
allows overlapping mounts to be queried.
To this end, four fsinfo() attributes are provided:
(1) FSINFO_ATTR_MOUNT_INFO.
This is a structure
