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

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.
Paolo, i re-implemented one reset patch in the Qemu side to call this ioctl(),
and did some tests on Windows and Linux guest, the Windows/Linux guest reboot
work well.
So, it is time for me to send this reset patch to Qemu community? or wait for
this kernel patchset merged? thanks!
Let's wait for this patch to be accepted first. I'll wait a little more
for Jarkko and Dave to comment on this, and include your "Tested-by".
I will also add cond_resched() on the final submission.
