git://git.kernel.org/pub/scm/linux/kernel/git/mkl/linux-can-next Marc Kleine-Budde says: ==================== pull-request: can-next 2022-06-25 this is a pull request of 22 patches for net-next/master. The first 2 patches target the xilinx driver. Srinivas Neeli's patch adds Transmitter Delay Compensation (TDC) support, a patch by me fixes a typo. The next patch is by me and fixes a typo in the m_can driver. Another patch by me allows the configuration of fixed bit rates without need for do_set_bittiming callback. The following 7 patches are by Vincent Mailhol and refactor the can-dev module and Kbuild, de-inline the can_dropped_invalid_skb() function, which has grown over the time, and drop outgoing skbs if the controller is in listen only mode. Max Staudt's patch fixes a reference in the networking/can.rst documentation. Vincent Mailhol provides 2 patches with cleanups for the etas_es58x driver. Conor Dooley adds bindings for the mpfs-can to the PolarFire SoC dtsi. Another patch by me allows the configuration of fixed data bit rates without need for do_set_data_bittiming callback. The last 5 patches are by Frank Jungclaus. They prepare the esd_usb driver to add support for the the CAN-USB/3 device in a later series. ==================== Signed-off-by: David S.

2022-06-26parisc: Fix flush_anon_page on PA8800/PA8900John David Anglin1-1/+4
Anonymous pages are allocated with the shared mappings colouring, SHM_COLOUR. Since the alias boundary on machines with PA8800 and PA8900 processors is unknown, flush_user_cache_page() might not flush all mappings of a shared anonymous page. Flushing the whole data cache flushes all mappings. This won't fix all coherency issues with shared mappings but it seems to work well in practice. I haven't seen any random memory faults in almost a month on a rp3440 running as a debian buildd machine. There is a small preformance hit.

2022-06-23s390/pai: Fix multiple concurrent event installationThomas Richter1-3/+12
Two different events such as pai_crypto/KM_AES_128/ and pai_crypto/KM_AES_192/ can be installed multiple times on the same CPU and the events are executed concurrently: # perf stat -e pai_crypto/KM_AES_128/ -C0 -a -- sleep 5 & # sleep 2 # perf stat -e pai_crypto/KM_AES_192/ -C0 -a -- true This results in the first event being installed two times with two seconds delay. The kernel does install the second event after the first event has been deleted and re-added, as can be seen in the traces: 13:48:47.600350 paicrypt_start event 0x1007 (event KM_AES_128) 13:48:49.599359 paicrypt_stop event 0x1007 (event KM_AES_128) 13:48:49.599198 paicrypt_start event 0x1007 13:48:49.599199 paicrypt_start event 0x1008 13:48:49.599921 paicrypt_event_destroy event 0x1008 13:48:52.601507 paicrypt_event_destroy event 0x1007 This is caused by functions event_sched_in() and event_sched_out() which call the PMU's add() and start() functions on schedule_in and the PMU's stop() and del() functions on schedule_out. This is correct for events attached to processes. The pai_crypto events are system-wide events and not attached to processes. Since the kernel common code can not be changed easily, fix this issue and do not reset the event count value to zero each time the event is added and started. Instead use a flag and zero the event count value only when called immediately after the event has been initialized. Therefore only the first invocation of the the event's add() function initializes the event count value to zero. The following invocations of the event's add() function leave the current event count value untouched.

2022-06-23s390/cpumf: Handle events cycles and instructions identicalThomas Richter1-1/+21
Events CPU_CYCLES and INSTRUCTIONS can be submitted with two different perf_event attribute::type values: - PERF_TYPE_HARDWARE: when invoked via perf tool predefined events name cycles or cpu-cycles or instructions. - pmu->type: when invoked via perf tool event name cpu_cf/CPU_CYLCES/ or cpu_cf/INSTRUCTIONS/. This invocation also selects the PMU to which the event belongs. Handle both type of invocations identical for events CPU_CYLCES and INSTRUCTIONS. They address the same hardware. The result is different when event modifier exclude_kernel is also set. Invocation with event modifier for user space event counting fails.

2022-06-22powerpc/powernv: wire up rng during setup_archJason A. Donenfeld3-16/+40
The platform's RNG must be available before random_init() in order to be useful for initial seeding, which in turn means that it needs to be called from setup_arch(), rather than from an init call. Complicating things, however, is that POWER8 systems need some per-cpu state and kmalloc, which isn't available at this stage. So we split things up into an early phase and a later opportunistic phase. This commit also removes some noisy log messages that don't add much.
