BXT supports following intermediate link rates for edp:
2.16GHz, 2.43GHz, 3.24GHz, 4.32GHz.
Adding support for programming the intermediate rates.
v2: Adding clock in bxt_clk_div struct and then look for the entry with
required rate (Ville)
v3: 'clock' has the selected value, no need to use link_bw or rate_select
for selecting pll(Ville)
v4: Make bxt_dp_clk_val const and remove size (Ville)
v5: Rebased
v6: Removed setting of vco while rebasing in v5, adding it back

Pull vfs fix from Al Viro:
"Off-by-one in d_walk()/__dentry_kill() race fix.
It's very hard to hit; possible in the same conditions as the original
bug, except that you need the skipped branch to contain all the
remaining evictables, so that the d_walk()-calling loop in
d_invalidate() decides there's nothing more to do and doesn't go for
another pass - otherwise that next pass will sweep the sucker.
So it's not too urgent, but seeing that the fix is obvious and the
original commit has spread into all -stable branches..."

There is just one configfs subsystem in the target code, so we might as
well add two helpers to reference / unreference it from the core code
instead of passing pointers to it around.
This fixes a regression introduced for v4.1-rc1 with commit 9ac8928e6,
where configfs_depend_item() callers using se_tpg_tfo->tf_subsys would
fail, because the assignment from the original target_core_subsystem[]
is no longer happening at target_register_template() time.

This fixes a bug uncovered by a recent driver core change that
modified the implementation of the ACPI_COMPANION_SET() macro to
strictly rely on its second argument to be either NULL or a valid
pointer to struct acpi_device.
As it turns out, pcibios_root_bridge_prepare() on x86 and ia64
works with the assumption that the only code path calling
pci_create_root_bus() is pci_acpi_scan_root() and therefore
the sysdata argument passed to it will always match the
expectations of pcibios_root_bridge_prepare(). That need not
be the case, however, and in particular it is not the case for
the Xen pcifront driver that passes a pointer to its own private
data strcture as sysdata to pci_scan_bus_parented() which then
passes it to pci_create_root_bus() and it ends up being used
incorrectly by pcibios_root_bridge_prepare().

looping indefinitely upon mounting NFS root.
Use conditional assembly to avoid a microMIPS code size regression.
Using $at unconditionally would cause such a regression as there are no
16-bit instruction encodings available for ALU operations using this
register. Using $v1 unconditionally would produce short microMIPS
encodings, but would prevent this register from being used across calls
to this function.
The extra LI operation introduced is free, replacing a NOP originally
scheduled into the delay slot of the branch that follows.

dm_merge_bvec() was originally added in f6fccb ("dm: introduce
merge_bvec_fn"). In that commit a value in sectors is converted to
bytes using << 9, and then assigned to an int. This code made
assumptions about the value of BIO_MAX_SECTORS.
A later commit 148e51 ("dm: improve documentation and code clarity in
dm_merge_bvec") was meant to have no functional change but it removed
the use of BIO_MAX_SECTORS in favor of using queue_max_sectors(). At
this point the cast from sector_t to int resulted in a zero value. The
fallout being dm_merge_bvec() would only allow a single page to be added
to a bio.
This interim fix is minimal for the benefit of stable@ because the more
comprehensive cleanup of passing a sector_t to all DM targets' merge
function will impact quite a few DM targets.

dm-multipath accepts 0 path mapping.
# echo '0 2097152 multipath 0 0 0 0' | dmsetup create newdev
Such a mapping can be used to release underlying devices while still
holding requests in its queue until working paths come back.
However, once the multipath device is created over blk-mq devices,
it rejects reloading of 0 path mapping:
# echo '0 2097152 multipath 0 0 1 1 queue-length 0 1 1 /dev/sda 1' \
| dmsetup create mpath1
# echo '0 2097152 multipath 0 0 0 0' | dmsetup load mpath1
device-mapper: reload ioctl on mpath1 failed: Invalid argument
Command failed
With following kernel message:
device-mapper: ioctl: can't change device type after initial table load.
DM tries to inherit the current table type using dm_table_set_type()
but it doesn't work as expected because of unnecessary check about
whether the target type is hybrid or not.
Hybrid type is for targets that work as either request-based or bio-based
and not required for blk-mq or non blk-mq checking.

When stacking request-based dm device on non blk-mq device and
device-mapper target could not map the request (error target is used,
multipath target with all paths down, etc), the WARN_ON_ONCE() in
free_rq_clone() will trigger when it shouldn't.
The warning was added by commit aa6df8d ("dm: fix free_rq_clone() NULL
pointer when requeueing unmapped request"). But free_rq_clone() with
clone->q == NULL is valid usage for the case where
dm_kill_unmapped_request() initiates request cleanup.
Fix this false warning by just removing the WARN_ON -- it only generated
false positives and was never useful in catching the intended case
(completing clone request not being mapped e.g. clone->q being NULL).

- Booting v4.1-rc kernel with old DTBs will fail with a fat warning
(require low-level debug to be seen), due to the adoption of stacked
IRQ domain. The first fix improves the situation by allowing kernel
boot up with old DTBs, although suspend/resume still breaks.
- Booting new kernel with old DTBs that do not have power-domain info

Without this frontbuffer flip when enabling planes PSR got compromised
and wasn't being enabled waiting forever on the flush that never
arrived.
Another solution would to create a enable_cursor function and split this
frontbuffer flip among the different plane enable and disable functions.
But if necessary this can be done in a follow up work. For now let's
just fix the regression.

The hotplug status is cached in hp_control, and will be passed on to
bottom halves through intel_hpd_irq_handler(), so we can clear the
sticky bits earlier.
While at it, drop the redundant logging of the hotplug status, which
will also be logged by pch_get_hpd_pins().

Split intel_hpd_irq_handler into platforms specific and platform
agnostic parts. The platform specific parts decode the registers into
information about which hpd pins triggered, and if they were long
pulses. The platform agnostic parts do further processing, such as
interrupt storm mitigation and scheduling bottom halves.

As the hpd loops have been merged together, we don't have to maintain
state for all hpd triggers.

Nothing in the two consecutive loops over hpd pins depends on state in a
larger context than the single hpd pin. If we skip the rest of the loop
on short hpd pulses, we can merge the two loops into one.
