[PATCH 0 of 2] xenpaging:speed up page-in
The following two patches are about how to speed up in xenpaging when page in pages.
On suse11-64 with 4G memory,if we page out 2G pages,it will cost about 15.5 seconds,
but take 2088 seconds to finish paging in.If page-in costs too much time,it will cause
unmesurable problems when vm or dom0 access the paged_out page,such as BSOD,crash.
What鈥檚 more,the dom0 is always in high I/O pressure.
