This is an optimization of a set of sgx-related codes, each of which is independent of the patch. Because the second and third patches have conflicting dependencies, these patches are put together.
--- v3 changes: * split free_cnt count and spin lock optimization into two patches
v2 changes: * review suggested changes
Tianjia Zhang (5): selftests/x86: Simplify the code to get vdso base address in sgx x86/sgx: Optimize the locking range in sgx_sanitize_section() x86/sgx: Optimize the free_cnt count in sgx_epc_section x86/sgx: Allows ioctl PROVISION to execute before CREATE x86/sgx: Remove redundant if conditions in sgx_encl_create
