tag v23-rc2
Tagger: Jarkko Sakkinen <jarkko.sakkinen@linux.intel.com>

x86/sgx: v23-rc1 patch set
* Return -EIO instead of -ECANCELED when ptrace() fails to read a TCS page.
* In the reclaimer, pin page before ENCLS[EBLOCK] because pinning can fail
(because of OOM) even in legit behaviour and after EBLOCK the reclaiming
flow can be only reverted by killing the whole enclave.
* Fixed SGX_ATTR_RESERVED_MASK. Bit 7 was marked as reserved while in fact
it should have been bit 6 (Table 37-3 in the SDM).
* Return -EPERM from SGX_IOC_ENCLAVE_INIT when ENCLS[EINIT] returns an SGX
error code.
* In v22 __uaccess_begin() was used to pin the source page in
__sgx_encl_add_page(). Switch to get_user_pages() in order to avoid
deadlock (mmap_sem might get locked twice in the same thread).
