arm64/mm: Drop THP conditionality from FORCE_MAX_ZONEORDER
79cc2ed 
Currently without THP being enabled, MAX_ORDER via FORCE_MAX_ZONEORDER gets
reduced to 11, which falls below HUGETLB_PAGE_ORDER for certain 16K and 64K
page size configurations. This is problematic which throws up the following
warning during boot as pageblock_order via HUGETLB_PAGE_ORDER order exceeds
MAX_ORDER.

This solves the problem via keeping FORCE_MAX_ZONEORDER unchanged with or
without THP on 16K and 64K page size configurations, making sure that the
HUGETLB_PAGE_ORDER (and pageblock_order) would never exceed MAX_ORDER.

KVM: arm64: Handle kvm_arm_init failure correctly in finalize_pkvm

Currently there is no synchronisation between finalize_pkvm() and
kvm_arm_init() initcalls. The finalize_pkvm() proceeds happily even if
kvm_arm_init() fails resulting in the following warning on all the CPUs
and eventually a HYP panic:

Fix it by checking for the successfull initialisation of kvm_arm_init()
in finalize_pkvm() before proceeding any futher.

selftests/bpf: Add various more tcx test cases
dbd1540 
Add several new tcx test cases to improve test coverage. This also includes
a few new tests with ingress instead of clsact qdisc, to cover the fix from
commit dc644b5 ("tcx: Fix splat in ingress_destroy upon tcx_entry_free").
