      drm/amdgpu: GPU vs CPU page size fixes in amdgpu_vm_bo_split_mapping · 38e624a1
      Michel Dänzer authored
      start / last / max_entries are numbers of GPU pages, pfn / count are
      numbers of CPU pages. Convert between them accordingly.
      
      Fixes badness on systems with > 4K page size.

      drm/amdgpu: Count disabled CRTCs in commit tail earlier · fe2a1965
      Lyude Paul authored
      This fixes a regression I accidentally reduced that was picked up by
      kasan, where we were checking the CRTC atomic states after DRM's helpers
      had already freed them. Example:

      So, we fix this by counting the number of CRTCs this atomic commit disabled
      early on in the function before their atomic states have been freed, then use
      that count later to do the appropriate number of RPM puts at the end of the
      function.

      Pull RISC-V updates from Palmer Dabbelt:
       "This contains some small RISC-V updates I'd like to target for 4.18.
      
        They are all fairly small this time. Here's a short summary, there's
        more info in the commits/merges:
      
         - a fix to __clear_user to respect the passed arguments.
      
         - enough support for the perf subsystem to work with RISC-V's ISA
           defined performance counters.
      
         - support for sparse and cleanups suggested by it.
      
         - support for R_RISCV_32 (a relocation, not the 32-bit ISA).
      
         - some MAINTAINERS cleanups.
      
         - the addition of CONFIG_HVC_RISCV_SBI to our defconfig, as it's
           always present.
      
        I've given these a simple build+boot test"
