Introduce an xarray based version array (VA) structure: struct sgx_va. The use of sgx_va can be later on extended to the following use cases: - A global VA for reclaimed SECS pages. - A global VA for reclaimed VA pages. Testing done while developing the patch: - With NUC7PJYH: https://www.intel.com/content/www/us/en/products/boards-kits/nuc/kits/nuc7pjyh.html - seq 10000 | xargs -I {} -P10000 ./test_sgx > /dev/null - The EPC size was set from BIOS to 32 MB.
