There is a proposed change to the miscdevice's behaviour on open(). Currently
file->private_data stays NULL, but only because we don't have an open-entry in
struct file_operations.
This may change so that private_data, more consistently, is always set to
struct miscdevice, not only *if* the driver has it's own open() routine and
fops-entry, see https://lkml.org/lkml/2014/12/4/939 and commit
94e4fe2cab
In short: If we rely on file->private_data being NULL, we should ensure
it is NULL ourselves.

This patch introduces a new data structure to represent advertising

The patch provide an API to get MPIC version for reusing the code.
Also, some other IP block may need MPIC version for their own use.
The API for external use is also provided.
This function had been previously added but was removed by commit
5e86bfde9c ("powerpc/mpic: remove unused functions") due to the

The /sys/kernel/mobility/migration interface was added all the way back
in 2.6.37. However, the drmgr userspace tool was never augmented to use
this interface to perfrom migrations. Instead it has continued using a
faux rtas call coupled with performing the device tree update processing
in userspace and communicating it back to the kernel via the ugly
/proc/ppc64/ofdt interface.
Up until 3.12 the device tree update code in the kernel was badly broken
and bit rotting. This code was fixed in 3.12 and is now utilized by the
kernel suspend code as of 3.15. The kernel is now better suited to
handle the post-mobility fixup of the device tree and drmgr should be
transitioned to using the sysfs migration interface.
This patch introduces the api_version sysfs file to /sys/kernel/mobility
as a means for drmgr to query the current implementation level of the
kernel migration code. This initial versioning indicates it is capable
of perfroming all current PAPR requirements for migration including the
post-mobility firmware activation and device tree update.

In the current parent mapping code, we can get duplicate or inconsistent
indexes, which leads to discrepancy between the number of elements in the
array and the number of parents. Until now, this was solved with some
reordering but this is not always possible.
This patch introduces index tables that are used to define the relations
between the PLL source and the hardware mux configuration value.
To accomplish this, here we do the following:
- Define a parent_map struct to map the relations between PLL source index
and register configuration value.
- Add a qcom_find_src_index() function for finding the index of a clock
matching the specific PLL configuration.
- Update the {set,get}_parent RCG functions use the newly introduced
parent_map struct.
- Convert all existing drivers to the new parent_map tables.

Currently, a RCG's M/N counter (used for fraction division) is
set to either 'bypass' (counter disabled) or 'dual edge' (counter
enabled) based on whether the corresponding rcg struct has a mnd
field specified and a non-zero N.
In the case where M and N are the same value, the M/N counter is
still enabled by code even though no division takes place.
Leaving the RCG in such a state can result in improper behavior.
This was observed with the DSI pixel clock RCG when M and N were
both set to 1.
Add an additional check (M != N) to enable the M/N counter only
when it's needed for fraction division.

pm_genpd_remove_device() tries hard to validate the generic PM domain
passed to it, but the validation is not complete.
dev->pm_domain contains a struct dev_pm_domain, which is the "base
class" of generic PM domains. Other users of dev_pm_domains include
stuff like vga_switheroo. Hence, a device could have a generic PM
domain or a vga_switcheroo PM domain in dev->pm_domain.
We need ot be certain that the PM domain is actually valid before we
try to remove it. We can do this easily as we have a way to get the
current validated generic PM domain for a struct device. This must
match the generic PM domain being requested for removal.
Convert the code to use this alternative validation method instead.

Commit c4db59d31e ("fs: don't reassign dirty inodes to
default_backing_dev_info") exposed DM to a latent race in free_dev() vs
add_disk() in relation to management of the device's minor number.
Fix this by refactoring free_dev() to match cleanup order of the
alloc_dev() error path. Move cleanup of the gendisk, queue, and bdev
to _before_ the cleanup of the idr managed minor number.
Also, purely due to cleanup that fell out during the free_dev() audit:
- adjust dm_blk_close() to access the gendisk's private_data under
the _minor_lock spinlock.
- move __dm_destroy()'s dm_get_live_table() call out from under the
_minor_lock spinlock.
