Commit c5c27a0a ("x86/stacktrace: Remove the pointless ULONG_MAX marker") removes ULONG_MAX marker from user stack trace entries but trace_user_stack_print() still uses the marker and it outputs unnecessary "??". For example: less-1911 [001] d..2 34.758944: <user stack trace> => <00007f16f2295910> => ?? => ?? => ?? => ?? => ?? => ?? => ?? The user stack trace code zeroes the storage before saving the stack, so if the trace is shorter than the maximum number of entries it can terminate the print loop if a zero entry is detected.

In nouveau_conn_reset(), if connector->state is true, __drm_atomic_helper_connector_destroy_state() will be called, but the memory pointed by asyc isn't freed. Memory leak happens in the following function __drm_atomic_helper_connector_reset(), where newly allocated asyc->state will be assigned to connector->state. So using nouveau_conn_atomic_destroy_state() instead of __drm_atomic_helper_connector_destroy_state to free the "old" asyc.

It turns out that while disabling i2c bus access from software when the GPU is suspended was a step in the right direction with: commit 342406e4 ("drm/nouveau/i2c: Disable i2c bus access after ->fini()") We also ended up accidentally breaking the vbios init scripts on some older Tesla GPUs, as apparently said scripts can actually use the i2c bus. Since these scripts are executed before initializing any subdevices, we end up failing to acquire access to the i2c bus which has left a number of cards with their fan controllers uninitialized. Luckily this doesn't break hardware - it just means the fan gets stuck at 100%. This also means that we've always been using our i2c busses before initializing them during the init scripts for older GPUs, we just didn't notice it until we started preventing them from being used until init. It's pretty impressive this never caused us any issues before! So, fix this by initializing our i2c pad and busses during subdev pre-init. We skip initializing aux busses during pre-init, as those are guaranteed to only ever be used by nouveau for DP aux transactions.

Previously center scaling would get scaling applied to it (when it was only supposed to center the image), and aspect-corrected scaling did not always correctly pick whether to reduce width or height for a particular combination of inputs/outputs.

Higher layers tend to add a lot of modes not actually in the EDID, such as the standard DMT modes. Changing this would be extremely intrusive to everyone, so just force the scaler more often. There are no practical cases we're aware of where a LVDS/eDP panel has multiple resolutions exposed, and i915 already does it this way.

There are two generations of tlb operation instruction for C-SKY. First generation is use mcr register and it need software do more things, second generation is use specific instructions, eg: tlbi.va, tlbi.vas, tlbi.alls We implemented the following functions: - flush_tlb_range (a range of entries) - flush_tlb_page (one entry) Above functions use asid from vma->mm to invalid tlb entries and we could use tlbi.vas instruction for newest generation csky cpu. - flush_tlb_kernel_range - flush_tlb_one Above functions don't care asid and it invalid the tlb entries only with vpn and we could use tlbi.vaas instruction for newest generat- ion csky cpu.

This patch only contains asid help code from arm for next patch to use. The asid allocator use five level check to reduce the cost of switch_mm. 1. Check if the asid version is the same (it's general) 2. Check reserved_asid which is set in rollover flush_context() and key point is to keep the same bit position with the current asid version instead of input version. 3. Check if the position of bitmap is free then it could be set & used directly. 4. find_next_zero_bit() (a little performance cost) 5. flush_context (this is the worst cost with increase current asid version) Check is level by level and cost is also higher with the next level. The reserved_asid and bitmap mechanism prevent unnecessary find_next_zero_bit(). The atomic 64 bit asid is also suitable for 32-bit system and it won't cost a lot in 1th 2th 3th level check. The operation of set/clear mm_cpumask was removed in arm64 compared to arm32. It seems no side effect on current arm64 system, but from software meaning it's wrong. Although csky also needn't it, we add it back for csky. The asid_per_ctxt is no use for csky and it reserves the lowest bits for other use, maybe: trust zone ? Ok, just keep it in csky copy. Seems it also could be used by other archs and it's worth to move asid code to generic in future.

The csky pmu counter may have different io width. When the counter is smaller then 64 bits and counter value is smaller than the old value, it will result to a extremely large delta value.
