[PATCH 0/3] KVM: selftests: access_tracking_perf_test fixes and cleanups

From: "Zenghui Yu (Huawei)" <zenghui.yu@xxxxxxxxx>

Patch 1 fixes a deterministic failure of access_tracking_perf_test when the
host page size is bigger than the guest's, e.g. the 4K guest modes on a 64K
arm64 host: page_idle tracks idleness per host page, so walk the test
region at that granularity. Patches 2 and 3 are two small cleanups found
along the way.

Tested on an arm64 host with 64K pages.

Zenghui Yu (Huawei) (3):
KVM: selftests: Fix access_tracking_perf_test for larger host page
size
KVM: selftests: Add missing newline to access_tracking_perf_test help
KVM: selftests: Remove destroy_cgroup() from access_tracking_perf_test
