I'm otherwise cool with that, except patch #2.
It's based on this series:
https://lore.kernel.org/linux-sgx/20210113233541.17669-1-jarkko@kernel.org/
It's not reasonable to create driver specific wrapper for sgx_free_epc_page() because there is exactly *2* call sites of the function in the driver. The driver contains 10 call sites (11 after my NUMA patches have been applied) of sgx_free_epc_page() in total.
Instead, it is better to add explicit EREMOVE to those call sites.
The wrapper only trashes the codebase. I'm not happy with it, given all the trouble to make it clean and sound.
