Unlike kqueue/kevent of BSD, the epoll of Linux could be
add/del by using different API on the fly.
This patch drops the notify used by mevent_add/del and
call epoll_ctl to add/delete target fd. Only keeps
global_head to track mevent added and makes the code
logic in mevent_dispatch() a littel bit simpler.
Another thing is related with epoll_ctl. If the target
fd is regular fd which doesn't support epoll, epoll_ctl
will return -1. When DM is start by systemd, the STDIO
is not mapped to terminal, epoll_ctl on STDIO could
return -1. Which block UOS boot. We only call mevent_add
after confirm STDIO is mapped to terminal.

In kernel 4.14, PAT is skipped to initialize if MTRR is not enabled,
while graphics driver need set WC to GGTT memory to accelerate memcpy,
if PAT is not initialized, default PAT register will treat UC- as
uncacheable, which will impact gfx performance. Change PAT default
register value to treat UC- as WC to workaroud this problem.
