+Subject: kthread: Extract KTHREAD_IS_PER_CPU
+
+From: Peter Zijlstra <peterz@infradead.org>
+
+[ Upstream commit ac687e6e8c26181a33270efd1a2e2241377924b0 ]
+
+There is a need to distinguish geniune per-cpu kthreads from kthreads
+that happen to have a single CPU affinity.
+
+Geniune per-cpu kthreads are kthreads that are CPU affine for
+correctness, these will obviously have PF_KTHREAD set, but must also
+have PF_NO_SETAFFINITY set, lest userspace modify their affinity and
+ruins things.
+
+However, these two things are not sufficient, PF_NO_SETAFFINITY is
+also set on other tasks that have their affinities controlled through
+other means, like for instance workqueues.
+
+Therefore another bit is needed; it turns out kthread_create_per_cpu()
+already has such a bit: KTHREAD_IS_PER_CPU, which is used to make
+kthread_park()/kthread_unpark() work correctly.
+
+Expose this flag and remove the implicit setting of it from
+kthread_create_on_cpu(); the io_uring usage of it seems dubious at
+best.

+Subject: objtool: Don't fail on missing symbol table
+
+From: Josh Poimboeuf <jpoimboe@redhat.com>
+
+[ Upstream commit 1d489151e9f9d1647110277ff77282fe4d96d09b ]
+
+Thanks to a recent binutils change which doesn't generate unused
+symbols, it's now possible for thunk_64.o be completely empty without
+CONFIG_PREEMPTION: no text, no data, no symbols.
+
+We could edit the Makefile to only build that file when
+CONFIG_PREEMPTION is enabled, but that will likely create confusion
+if/when the thunks end up getting used by some other code again.
+
+Just ignore it and move on.

+Subject: platform/x86: touchscreen_dmi: Add swap-x-y quirk for Goodix
+ touchscreen on Estar Beauty HD tablet
+
+From: Hans de Goede <hdegoede@redhat.com>
+
+[ Upstream commit 46c54cf2706122c37497896d56d67b0c0aca2ede ]
+
+The Estar Beauty HD (MID 7316R) tablet uses a Goodix touchscreen,
+with the X and Y coordinates swapped compared to the LCD panel.
+
+Add a touchscreen_dmi entry for this adding a "touchscreen-swapped-x-y"
+device-property to the i2c-client instantiated for this device before
+the driver binds.
+
+This is the first entry of a Goodix touchscreen to touchscreen_dmi.c,
+so far DMI quirks for Goodix touchscreen's have been added directly
+to drivers/input/touchscreen/goodix.c. Currently there are 3
+DMI tables in goodix.c:
+1. rotated_screen[] for devices where the touchscreen is rotated
+ 180 degrees vs the LCD panel
+2. inverted_x_screen[] for devices where the X axis is inverted
+3. nine_bytes_report[] for devices which use a non standard touch
+ report size
+
+Arguably only 3. really needs to be inside the driver and the other
+2 cases are better handled through the generic touchscreen DMI quirk
+mechanism from touchscreen_dmi.c, which allows adding device-props to
+any i2c-client. Esp. now that goodix.c is using the generic
+touchscreen_properties code.
+
+Alternative to the approach from this patch we could add a 4th
+dmi_system_id table for devices with swapped-x-y axis to goodix.c,
+but that seems undesirable.

+Subject: scsi: ibmvfc: Set default timeout to avoid crash during migration
+
+From: Brian King <brking@linux.vnet.ibm.com>
+
+[ Upstream commit 764907293edc1af7ac857389af9dc858944f53dc ]
+
+While testing live partition mobility, we have observed occasional crashes
+of the Linux partition. What we've seen is that during the live migration,
+for specific configurations with large amounts of memory, slow network
+links, and workloads that are changing memory a lot, the partition can end
+up being suspended for 30 seconds or longer. This resulted in the following
+scenario:
+
+CPU 0 CPU 1
+------------------------------- ----------------------------------
+scsi_queue_rq migration_store
+ -> blk_mq_start_request -> rtas_ibm_suspend_me
+ -> blk_add_timer -> on_each_cpu(rtas_percpu_suspend_me
+ _______________________________________V
+ |
+ V
+ -> IPI from CPU 1
+ -> rtas_percpu_suspend_me
+ -> __rtas_suspend_last_cpu
+
+-- Linux partition suspended for > 30 seconds --
+ -> for_each_online_cpu(cpu)
+ plpar_hcall_norets(H_PROD
+ -> scsi_dispatch_cmd
+ -> scsi_times_out
+ -> scsi_abort_command
+ -> queue_delayed_work
+ -> ibmvfc_queuecommand_lck
+ -> ibmvfc_send_event
+ -> ibmvfc_send_crq
+ - returns H_CLOSED
+ <- returns SCSI_MLQUEUE_HOST_BUSY
+-> __blk_mq_requeue_request
+
+ -> scmd_eh_abort_handler
+ -> scsi_try_to_abort_cmd
+ - returns SUCCESS
+ -> scsi_queue_insert
+
+Normally, the SCMD_STATE_COMPLETE bit would protect against the command
+completion and the timeout, but that doesn't work here, since we don't
+check that at all in the SCSI_MLQUEUE_HOST_BUSY path.
+
+In this case we end up calling scsi_queue_insert on a request that has
+already been queued, or possibly even freed, and we crash.
+
+The patch below simply increases the default I/O timeout to avoid this race
+condition. This is also the timeout value that nearly all IBM SAN storage
+recommends setting as the default value.

+Subject: scsi: scsi_transport_srp: Don't block target in failfast state
+
+From: Martin Wilck <mwilck@suse.com>
+
+[ Upstream commit 72eeb7c7151302ef007f1acd018cbf6f30e50321 ]
+
+If the port is in SRP_RPORT_FAIL_FAST state when srp_reconnect_rport() is
+entered, a transition to SDEV_BLOCK would be illegal, and a kernel WARNING
+would be triggered. Skip scsi_target_block() in this case.

+Subject: selftests/powerpc: Only test lwm/stmw on big endian
+
+From: Michael Ellerman <mpe@ellerman.id.au>
+
+[ Upstream commit dd3a44c06f7b4f14e90065bf05d62c255b20005f ]
+
+Newer binutils (>= 2.36) refuse to assemble lmw/stmw when building in
+little endian mode. That breaks compilation of our alignment handler
+test:
+
+ /tmp/cco4l14N.s: Assembler messages:
+ /tmp/cco4l14N.s:1440: Error: `lmw' invalid when little-endian
+ /tmp/cco4l14N.s:1814: Error: `stmw' invalid when little-endian
+ make[2]: *** [../../lib.mk:139: /output/kselftest/powerpc/alignment/alignment_handler] Error 1
+
+These tests do pass on little endian machines, as the kernel will
+still emulate those instructions even when running little
+endian (which is arguably a kernel bug).
+
+But we don't really need to test that case, so ifdef those
+instructions out to get the alignment test building again.

+Subject: workqueue: Restrict affinity change to rescuer
+
+From: Peter Zijlstra <peterz@infradead.org>
+
+[ Upstream commit 640f17c82460e9724fd256f0a1f5d99e7ff0bda4 ]
+
+create_worker() will already set the right affinity using
+kthread_bind_mask(), this means only the rescuer will need to change
+it's affinity.
+
+Howveer, while in cpu-hot-unplug a regular task is not allowed to run
+on online&&!active as it would be pushed away quite agressively. We
+need KTHREAD_IS_PER_CPU to survive in that environment.
+
+Therefore set the affinity after getting that magic flag.
