Merge branch 'etnaviv/next' of https://git.pengutronix.de/git/lst/linux into drm-next

- fix for potential out-of-bounds reads in the perfmon ioctl
  implementation from Christian
- override to expose proper feature flags for the GC400 found on the
  STM32MP1 SoC, also from Christian
- Guido fixed an issue where we would spuriously fail to enter
  runtime suspend due to a new GPU engine status bit on GC7000
- tree-wide change from Gustavo to get rid of zero-length arrays
- fix for missed TS cache flush on GC7000, leading to spurious
  MMU faults from me
- request pages from DMA32 zone on systems where we can't address
  all present memory from me
