[PATCH v3 0/5] Some optimizations related to sgx

[Tianjia Zhang]

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
