Enabling spi6 caused boot loop on my device(Huawei Matebook E Go),

	&spi6 {

After looking into this, I found the clocks for spi0 to spi7 are
wrong, we can derive the correct clocks from the regular pattern
between spi8 to spi15, spi16 to spi23. Or we can verify it according
to the hex file of BSRC_QSPI.bin(From windows driver qcspi8280.cab)

This patch adds support for MEDIUM PARTITION PAGE in MODE SELECT and the
FORMAT MEDIUM command for tapes. After these additions, the virtual tape
can be partitioned containing either one or two partitions. The POFM flag
in the mode page is set, meaning that the FORMAT MEDIUM command must be
used to create the partitioning defined in the mode page.

e1ac21310a scsi: scsi_debug: Add write support with block lengths and 4 bytes of data
The tape is implemented as fixed number (10 000) of 8-byte units.  The
first four bytes of a unit contains the type of the unit (data block,
filemark or end-of-data mark). If the units is a data block, the first four
bytes contain the block length and the remaining four bytes the first bytes
of written data. This allows the user to use tags to see that the read
block is what it was supposed to be.

The tape can contain two partitions. Initially it is formatted as one
partition consisting of all 10 000 units.

This patch adds the WRITE(6) command for tapes and the WRITE FILEMARKS (6)
command. The REWIND command is updated.

b899434857 cpufreq/amd-pstate: Remove the unnecessary cpufreq_update_policy call
The update_limits callback is only called in two conditions.

* When the preferred core rankings change. In which case, we just need to
change the prefcore ranking in the cpudata struct. As there are no changes
to any of the perf values, there is no need to call cpufreq_update_policy()

* When the _PPC ACPI object changes, i.e. the highest allowed Pstate
changes. The _PPC object is only used for a table based cpufreq driver
like acpi-cpufreq, hence is irrelevant for CPPC based amd-pstate.

Hence, the cpufreq_update_policy() call becomes unnecessary and can be
removed.

6ceb877d5c cpufreq/amd-pstate: Modify the min_perf calculation in adjust_perf callback
Instead of setting a fixed floor at lowest_nonlinear_perf, use the
min_limit_perf value, so that it gives the user the freedom to lower the
floor further.

There are two minimum frequency/perf limits that we need to consider in
the adjust_perf callback. One provided by schedutil i.e. the sg_cpu->bw_min
value passed in _min_perf arg, another is the effective value of
min_freq_qos request that is updated in cpudata->min_limit_perf. Modify the
code to use the bigger of these two values.

c67c2332f8 firmware: arm_ffa: Skip the first/partition ID when parsing vCPU list
The FF-A notification id list received in response to the call
FFA_NOTIFICATION_INFO_GET is encoded as: partition ID followed by 0 or
more vCPU ID. The count includes all of them.

Fix the issue by skipping the first/partition ID so that only the list
of vCPU IDs are processed correctly for a given partition ID. The first/
partition ID is read before the start of the loop.

201b62ccc8 bpf: Refactor check_ctx_access()
Reduce the variable passing madness surrounding check_ctx_access().
Currently, check_mem_access() passes many pointers to local variables to
check_ctx_access(). They are used to initialize "struct
bpf_insn_access_aux info" in check_ctx_access() and then passed to
is_valid_access(). Then, check_ctx_access() takes the data our from
info and write them back the pointers to pass them back. This can be
simpilified by moving info up to check_mem_access().

No functional change.

eb963d7948 clk: sunxi-ng: h616: Reparent GPU clock during frequency changes
The H616 manual does not state that the GPU PLL supports
dynamic frequency configuration, so we must take extra care when changing
the frequency. Currently any attempt to do device DVFS on the GPU lead
to panfrost various ooops, and GPU hangs.

The manual describes the algorithm for changing the PLL
frequency, which the CPU PLL notifier code already support, so we reuse
that to reparent the GPU clock to GPU1 clock during frequency
changes.
