ti_sci_intr_irq_domain_free() assumes that out_irq of intr is stored in
data->chip_data and uses it for calling ti_sci irq_free() and then
mark the out_irq as available resource. But ti_sci_intr_irq_domain_alloc()
is storing p_hwirq(parent's hardware irq) which is translated from out_irq.
This is causing resource leakage and eventually out_irq resources might
be exhausted. Fix ti_sci_intr_irq_domain_alloc() by storing the out_irq
in data->chip_data.

[ Upstream commit f65607cdbc6b0da356ef5a22552ddd9313cf87a0 ]
When we set up a TDLS station, we set sta->sta.bandwidth solely based
on the capabilities, because the "what's the current bandwidth" check
is bypassed and only applied for other types of stations.
This leads to the unfortunate scenario that the sta->sta.bandwidth is
160 MHz if both stations support it, but we never actually configure
this bandwidth unless the AP is already using 160 MHz; even for wider
bandwidth support we only go up to 80 MHz (at least right now.)
For iwlwifi, this can also lead to firmware asserts, telling us that
we've configured the TX rates for a higher bandwidth than is actually
available due to the PHY configuration.
For non-TDLS, we check against the interface's requested bandwidth,
but we explicitly skip this check for TDLS to cope with the wider BW
case. Change this to
(a) still limit to the TDLS peer's own chandef, which gets factored
into the overall PHY configuration we request from the driver,
and
(b) limit it to when the TDLS peer is authorized, because it's only
factored into the channel context in this case.

[ Upstream commit 14653942de7f63e21ece32e3901f09a248598a43 ]
The R-Car V3U clock driver defines the R and OSC clocks using R-Car Gen3
clock types. However, The R-Car V3U clock driver does not use the R-Car
Gen3 clock driver core, hence registering the R and OSC clocks fails:
renesas-cpg-mssr e6150000.clock-controller: Failed to register core clock osc: -22
renesas-cpg-mssr e6150000.clock-controller: Failed to register core clock r: -22
Fix this by introducing clock definition macros specific to R-Car V3U.
Note that rcar_r8a779a0_cpg_clk_register() already handled the related
clock types. Drop the now unneeded include of rcar-gen3-cpg.h.

There isn't any need to overwrite the mode here in the driver with what
has been detected by the firmware, such as DT or ACPI. In fact, if we
use the SPI CS gpio descriptor feature we will overwrite the mode with
SPI_MODE_0 where it already contains SPI_MODE_0 and more importantly
SPI_CS_HIGH. Clearing the SPI_CS_HIGH bit causes the CS line to toggle
when the device is probed when it shouldn't change, confusing the driver
and making it fail to probe. Drop the assignment and let the spi core
take care of it.

Fix to restore BTF if single-stepping causes a page fault and
it is cancelled.
Usually the BTF flag was restored when the single stepping is done
(in resume_execution()). However, if a page fault happens on the
single stepping instruction, the fault handler is invoked and
the single stepping is cancelled. Thus, the BTF flag is not
restored.

[ Upstream commit ca9364dde50daba93eff711b4b945fd08beafcc2 ]
Since commit b4868b44c5 ("NFSv4: Wait for stateid updates after
CLOSE/OPEN_DOWNGRADE"), every inter server copy operation suffers 5
seconds delay regardless of the size of the copy. The delay is from
nfs_set_open_stateid_locked when the check by nfs_stateid_is_sequential
fails because the seqid in both nfs4_state and nfs4_stateid are 0.
Fix by modifying nfs4_init_cp_state to return the stateid with seqid 1
instead of 0. This is also to conform with section 4.8 of RFC 7862.
Here is the relevant paragraph from section 4.8 of RFC 7862:
A copy offload stateid's seqid MUST NOT be zero. In the context of a
copy offload operation, it is inappropriate to indicate "the most
recent copy offload operation" using a stateid with a seqid of zero
(see Section 8.2.2 of [RFC5661]). It is inappropriate because the
stateid refers to internal state in the server and there may be
several asynchronous COPY operations being performed in parallel on
the same file by the server. Therefore, a copy offload stateid with
a seqid of zero MUST be considered invalid.
