* drm/vmwgfx: Replace vmw_dma_buffer with vmw_buffer_objectThomas Hellstrom2018-07-0319-568/+567
| | | | | | | | | | | | | | | | | | Initially vmware buffer objects were only used as DMA buffers, so the name DMA buffer was a natural one. However, currently they are used also as dumb buffers and MOBs backing guest backed objects so renaming them to buffer objects is logical. Particularly since there is a dmabuf subsystem in the kernel where a dma buffer means something completely different. This also renames user-space api structures and IOCTL names correspondingly, but the old names remain defined for now and the ABI hasn't changed. There are a couple of minor style changes to make checkpatch happy.

* locking: Implement an algorithm choice for Wound-Wait mutexesThomas Hellstrom2018-07-032-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current Wound-Wait mutex algorithm is actually not Wound-Wait but Wait-Die. Implement also Wound-Wait as a per-ww-class choice. Wound-Wait is, contrary to Wait-Die a preemptive algorithm and is known to generate fewer backoffs. Testing reveals that this is true if the number of simultaneous contending transactions is small. As the number of simultaneous contending threads increases, Wait-Wound becomes inferior to Wait-Die in terms of elapsed time. Possibly due to the larger number of held locks of sleeping transactions. Update documentation and callers.

But, if the scheduled work item is executed after psr_enable(), we end up printing warnings as PSR is already enabled and active. So, put the cancel_work call back in psr_disable().
