Hi Boris,

Sorry that we found a bug in below patch in series:

[PATCH v2 03/25] x86/sgx: Wipe out EREMOVE from sgx_free_epc_page()

that I made a mistake when copying & pasting, which results in SECS page and va_page
not being freed correctly in sgx_encl_release().

Sorry for the mistake. I will send out another version with that fixed.
