Based on discussions from the previous week(end), this series implements a ioctl that performs EREMOVE on all pages mapped by a /dev/sgx_vepc file descriptor. Other possibilities, such as closing and reopening the device, are racy. The patches are untested, but I am posting them because they are simple and so that Yang Zhong can try using them in QEMU.
