perf/smmuv3: Validate groups for global filtering
mainline inclusion from mainline-v5.3-rc1 commit 3c934735 category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I4A1XO CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=3c9347351a6ea1234aa647b36f89052de050d2a2 ------------------------------------------------------------------------ With global filtering, it becomes possible for users to construct self-contradictory groups with conflicting filters. Make sure we cover that when initially validating events. Signed-off-by:Robin Murphy <robin.murphy@arm.com> Signed-off-by:
