2022-10-06drm/amd/display: Remove OPTC lock checkRodrigo Siqueira
At some point, we decided to blank HUBP during pixel data blank, and to handle that, we added some OPTC lock checks. Later, we realized that this change caused multiple regression, and we removed it. Nevertheless, we still have some leftovers that might affect some ASIC behavior, and this commit drops those changes to keep the code consistent.

2022-10-06drm/amd/display: Update DCN321 hook that deals with pipe aquireRodrigo Siqueira
DCN provides a hook to check if we can have a new pipe allocation based on some DC constraints. If the current configuration supports the new pipe request, DC updates its context; otherwise, it will keep the same configuration. This behavior is similar across multiple ASICs, and for this reason, we reused DCN20 on DCN321. However, this DCN32x has some peculiarities which require its function to avoid weird pipe split issues. This commit update this issue by using dcn32_acquire_idle_pipe_for_head_pipe_in_layer instead of dcn20_acquire_idle_pipe_for_layer.

DCN315 has to always allow pstate change or SMU will hang. This workaround achieves this by applying a low pstate change latency to be used when pstate is calculated to be unsupported. This lower latency only accounts for memory retraining; a previous change handles locking in the highest available pstate allowing us to minimize required latency hiding to only account for memory retraining.

2022-10-06perf test: Introduce script for data symbol testingLeo Yan
The test is designed with a data structure with 64-byte alignment, it has two fields "data1" and "data2", and other fields are reserved. Using the "perf mem" command, we can record and report memory samples for a self-contained workload with 1 second duration. If no samples are obtained for the data structure "buf1", it reports failure; and by checking the offset in structure "buf1", if the memory samples aren't for the "data1" and "data2" fields, it means wrong data symbol parsing and returns failure.

2022-10-07powerpc: Don't add __powerpc_ prefix to syscall entry pointsMichael Ellerman
When using syscall wrappers the __SYSCALL_DEFINEx() and related macros add a "__powerpc_" prefix to all syscall entry points. So for example sys_mmap becomes __powerpc_sys_mmap. This risks breaking workflows and tools that expect the old naming scheme. At a minimum setting a breakpoint on eg. sys_mmap with gdb no longer works. There seems to be no compelling reason to add the "__powerpc_" prefix, other than that it follows what some other arches do (x86, arm64, s390). But unlike other arches powerpc doesn't always enable syscall wrappers, so the syscall entry points can change name depending on CONFIG options. For those reasons drop the "__powerpc_" prefix, reverting to the existing naming. Doing so reveals two prototypes in signal.h that have the incorrect type when syscall wrappers are enabled. There are already prototypes for both functions in syscalls.h, so drop the ones from signal.h.

2022-10-06SUNRPC: Add a helper to allow pNFS drivers to selectively cancel RPC callsTrond Myklebust
Add the helper rpc_cancel_tasks(), which uses a caller-defined selection function to define a set of in-flight RPC calls to cancel. This is mainly intended for pNFS drivers which are subject to a layout recall, and which may therefore want to cancel all pending I/O using that layout in order to redrive it after the layout recall has been satisfied.

2022-10-06sched/core: Merge cpumask_andnot()+for_each_cpu() into for_each_cpu_andnot()Valentin Schneider

2022-10-06lib/test_cpumask: Add for_each_cpu_and(not) testsValentin Schneider
Following the recent introduction of for_each_andnot(), add some tests to ensure for_each_cpu_and(not) results in the same as iterating over the result of cpumask_and(not)(). Suggested-by: Yury Norov <yury.norov@gmail.com> Signed-off-by: Valentin Schneider <vschneid@redhat.com>
2022-10-06cpumask: Introduce for_each_cpu_andnot()Valentin Schneider
for_each_cpu_and() is very convenient as it saves having to allocate a temporary cpumask to store the result of cpumask_and(). The same issue applies to cpumask_andnot() which doesn't actually need temporary storage for iteration purposes. Following what has been done for for_each_cpu_and(), introduce for_each_cpu_andnot().

2022-10-06ARM/dma-mappіng: don't override ->dma_coherent when set from a bus notifierChristoph Hellwig
Commit ae626eb97376 ("ARM/dma-mapping: use dma-direct unconditionally") caused a regression on the mvebu platform, wherein devices that are dma-coherent are marked as dma-noncoherent, because although mvebu_hwcc_notifier() after that commit still marks then as coherent, the arm_coherent_dma_ops() function, which is called later, overwrites this setting, since it is being called from drivers/of/device.c with coherency parameter determined by of_dma_is_coherent(), and the device-trees do not declare the 'dma-coherent' property. Fix this by defaulting never clearing the dma_coherent flag in arm_coherent_dma_ops().

2022-10-06mmc: core: Add SD card quirk for broken discardAvri Altman
Some SD-cards from Sandisk that are SDA-6.0 compliant reports they supports discard, while they actually don't. This might cause mk2fs to fail while trying to format the card and revert it to a read-only mode. To fix this problem, let's add a card quirk (MMC_QUIRK_BROKEN_SD_DISCARD) to indicate that we shall fall-back to use the legacy erase command instead.
