2021-08-20dm ima: add version info to dm related events in ima logTushar Sugandhi
The DM events present in the ima log contain various attributes in the key=value format. The attributes' names/values may change in future, and new attributes may also get added. The attestation server needs some versioning to determine which attributes are supported and are expected in the ima log. Add version information to the DM events present in the ima log to help attestation servers to correctly process the attributes across different versions.

2021-08-20dm ima: prefix dm table hashes in ima log with hash algorithmTushar Sugandhi
The active/inactive table hashes measured in the ima log do not contain the information about hash algorithm. This information is useful for the attestation servers to recreate the hashes and compare them with the ones present in the ima log to verify the table contents. Prefix the table hashes in various DM events in ima log with the hash algorithm used to compute those hashes.

2021-08-20RDMA/rxe: Zero out index member of struct rxe_queueXiao Yang
1) New index member of struct rxe_queue was introduced but not zeroed so the initial value of index may be random. 2) The current index is not masked off to index_mask. In this case producer_addr() and consumer_addr() will get an invalid address by the random index and then accessing the invalid address triggers the following panic: "BUG: unable to handle page fault for address: ffff9ae2c07a1414" Fix the issue by using kzalloc() to zero out index member.

2021-08-20platform/x86/intel: pmc/core: Add Alder Lake low power mode support for pmc coreGayatri Kammela
Alder Lake has 14 status registers that are memory mapped. These registers show the status of the low power mode requirements. The registers are latched on every C10 entry or exit and on every s0ix.y entry/exit. Accessing these registers is useful for debugging any low power related activities. Thus, add debugfs entry to access low power mode status registers.

2021-08-20drm/amdgpu: Cancel delayed work when GFXOFF is disabledMichel Dänzer
schedule_delayed_work does not push back the work if it was already scheduled before, so amdgpu_device_delay_enable_gfx_off ran ~100 ms after the first time GFXOFF was disabled and re-enabled, even if GFXOFF was disabled and re-enabled again during those 100 ms. This resulted in frame drops / stutter with the upcoming mutter 41 release on Navi 14, due to constantly enabling GFXOFF in the HW and disabling it again (for getting the GPU clock counter). To fix this, call cancel_delayed_work_sync when the disable count transitions from 0 to 1, and only schedule the delayed work on the reverse transition, not if the disable count was already 0. This makes sure the delayed work doesn't run at unexpected times, and allows it to be lock-free. v2: * Use cancel_delayed_work_sync & mutex_trylock instead of mod_delayed_work. v3: * Make amdgpu_device_delay_enable_gfx_off lock-free (Christian König) v4: * Fix race condition between amdgpu_gfx_off_ctrl incrementing adev->gfx.gfx_off_req_count and amdgpu_device_delay_enable_gfx_off checking for it to be 0 (Evan Quan) Cc: stable@vger.kernel.org Reviewed-by: Evan Quan <evan.quan@amd.com> Reviewed-by: Lijo Lazar <lijo.lazar@amd.com> # v3 Acked-by: Christian König <christian.koenig@amd.com> # v3 Signed-off-by: Michel Dänzer <mdaenzer@redhat.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2021-08-20drm/amd/pm: a quick fix for "divided by zero" errorEvan Quan
Considering Arcturus is a dedicated ASIC for computing, it will be more proper to drop the support for fan speed reading and setting. That's on the TODO list.

2021-08-20e1000e: Do not take care about recovery NVM checksumSasha Neftin
On new platforms, the NVM is read-only. Attempting to update the NVM is causing a lockup to occur. Do not attempt to write to the NVM on platforms where it's not supported. Emit an error message when the NVM checksum is invalid.

2021-08-20iommu/io-pgtable: Abstract iommu_iotlb_gather accessRobin Murphy
Previously io-pgtable merely passed the iommu_iotlb_gather pointer through to helpers, but now it has grown its own direct dereference. This turns out to break the build for !IOMMU_API configs where the structure only has a dummy definition. It will probably also crash drivers who don't use the gather mechanism and simply pass in NULL. Wrap this dereference in a suitable helper which can both be stubbed out for !IOMMU_API and encapsulate a NULL check otherwise.

2021-08-20irqchip/gic-v3: Fix priority comparison when non-secure priorities are usedChen-Yu Tsai
When non-secure priorities are used, compared to the raw priority set, the value read back from RPR is also right-shifted by one and the highest bit set. Add a macro to do the modifications to the raw priority when doing the comparison against the RPR value. This corrects the pseudo-NMI behavior when non-secure priorities in the GIC are used. Tested on 5.10 with the "IPI as pseudo-NMI" series [1] applied on MT8195.

2021-08-20net: ipa: kill ipa_clock_get()Alex Elder
The only remaining user of the ipa_clock_{get,put}() interface is ipa_isr_thread(). Replace calls to ipa_clock_get() there calling pm_runtime_get_sync() instead. And call pm_runtime_put() there rather than ipa_clock_put(). Warn if we ever get an error. With that, we can get rid of ipa_clock_get() and ipa_clock_put().

2021-08-20net: ipa: don't use ipa_clock_get() in "ipa_modem.c"Alex Elder
When we open or close the modem network device we need to ensure the hardware is powered. Replace the callers of ipa_clock_get() found in ipa_open() and ipa_stop() with calls to pm_runtime_get_sync(). If an error is returned, simply return that error to the caller (without any error or warning message). This could conceivably occur if the function was called while the system was suspended, but that really shouldn't happen. Replace corresponding calls to ipa_clock_put() with pm_runtime_put() also. If the modem crashes we also need to ensure the hardware is powered to recover. If getting power returns an error there's not much we can do, but at least report the error. (Ideally the remoteproc SSR code would ensure the AP was not suspended when it sends the notification, but that is not (yet) the case.)
