This v2 series implements selftests targeting the feature floated by Chao via: https://lore.kernel.org/linux-mm/20220310140911.50924-1-chao.p.peng@linux.in...

Below changes aim to test the fd based approach for guest private memory in context of normal (non-confidential) VMs executing on non-confidential platforms.

priv_memfd_test.c file adds a suite of selftests to access private memory from the guest via private/shared accesses and checking if the contents can be leaked to/accessed by vmm via shared memory view.

Updates in V2:

1. Tests are added to exercise implicit/explicit memory conversion paths.
2. Test is added to exercise UPM feature without double memory allocation.
