2023-04-17wifi: mt76: mt7921e: fix probe timeout after rebootQuan Zhou
In system warm reboot scene, due to the polling timeout(now 1000us) is too short to wait dma idle in time, it may make driver probe fail with error code -ETIMEDOUT. Meanwhile, we also found the dma may take around 70ms to enter idle state. Change the polling idle timeout to 100ms to avoid the probabilistic probe fail. Tested pass with 5000 times warm reboot on x86 platform.

2023-04-17SUNRPC: Fix failures of checksum Kunit testsChuck Lever
Scott reports that when the new GSS krb5 Kunit tests are built as a separate module and loaded, the RFC 6803 and RFC 8009 checksum tests all fail, even though they pass when run under kunit.py. It appears that passing a buffer backed by static const memory to gss_krb5_checksum() is a problem. A printk in checksum_case() shows the correct plaintext, but by the time the buffer has been converted to a scatterlist and arrives at checksummer(), it contains all zeroes. Replacing this buffer with one that is dynamically allocated fixes the issue.

2023-04-17arm64/cpufeature: Use helper macro to specify ID register for capabilitesMark Brown
When defining which value to look for in a system register field we currently manually specify the register, field shift, width and sign and the value to look for. This opens the potential for error with for example the wrong field width or sign being specified, an enumeration value for a different similarly named field or letting something be initialised to 0. Since we now generate defines for all the ID registers we now have named constants for all of these things generated from the system register description, meaning that we can generate initialisation for all the fields used in matching from a minimal specification of register, field and match value. This is both shorter and eliminates or makes build failures several potential errors. No change in the generated binary.

2023-04-17drivers/perf: hisi: add NULL check for nameJunhao He
When allocations fails that can be NULL now. If the name provided is NULL, then the initialization process of the PMU type and dev will be skipped in function perf_pmu_register(). Consequently, the PMU will not be able to register into the kernel. Moreover, in the case of unregister the PMU, the function device_del() will need to handle NULL pointers, which potentially can cause issues. So move this allocation above the cpuhp_state_add_instance() and directly return if it does fail.

2023-04-17arm64/cpufeature: Consistently use symbolic constants for min_field_valueMark Brown
A number of the cpufeatures use raw numbers for the minimum field values specified rather than symbolic constants. In preparation for the use of helper macros replace all these with the appropriate constants. No change in the generated binary.
