Subject: [PATCH 0/6] Intel Secure Guard Extensions

Intel(R) SGX is a set of CPU instructions that can be used by
applications to set aside private regions of code and data.  The code
outside the enclave is disallowed to access the memory inside the
enclave by the CPU access control.

The firmware uses PRMRR registers to reserve an area of physical memory
called Enclave Page Cache (EPC). There is a hardware unit in the
processor called Memory Encryption Engine. The MEE encrypts and decrypts
the EPC pages as they enter and leave the processor package.

Jarkko Sakkinen (5):
  x86, sgx:  common macros and definitions
  intel_sgx: driver for Intel Secure Guard eXtensions
  intel_sgx: ptrace() support for the driver
  intel_sgx: driver documentation
  intel_sgx: TODO file for the staging area

Kai Huang (1):
  x86: add SGX definition to cpufeature
