KVM: arm64: Mark some VM-scoped allocations as __GFP_ACCOUNT
Generally speaking, any memory allocations that can be associated with a
particular VM should be charged to the cgroup of its process.
Nonetheless, there are a couple spots in KVM/arm64 that aren't currently
accounted:
- the ccsidr array containing the virtualized cache hierarchy
- the cpumask of supported cpus, for use of the vPMU on heterogeneous
systems
Go ahead and set __GFP_ACCOUNT for these allocations.
