[PATCH v3 0/3] Count pKVM stage-2 usage in secondary pagetable stat

[Vincent Donnefort]

This series allows to count stage-2 related memory when using pKVM. The
value can be found in the /proc/meminfo field SecPageTables.

Changes since v2: https://lore.kernel.org/all/20250304134347.369854-1-vdonnefort@google.com/
  - Pass a pointer to kvm_hyp_memcache instead of just the flags
