Don't implement native_kmap_atomic_pte for !HIGHPTE case; it is never needed, never called, and leaving it in is just plain confusing.

Get blktap2 running on pvops. This mainly adds eventfd support to the userland code. Based on some prior cleanup to tapdisk-queue and the server object. We had most of that in XenServer for a while, so I kept it stacked. 1. Clean up IPC and AIO init in tapdisk-server. [I think tapdisk-ipc in blktap2 is basically obsolete. Pending a later patch to remove it?] 2. Split tapdisk-queue into

Hi All, I followed the instructions here at http://bderzhavets.wordpress.com/2009/06/10/setup-fedora-11-pv-domu-at-xen-3-4-1-dom0-kernel-2-6-30-rc6-tip-on-top-of-fedora-11/ However, when I do a "make menuconfig", I cannot see any XEN related configuration options. What am I missing? Thank you. Mr. Teo En Ming Dip(Mechatronics Engineering) BEng(Hons)(Mechanical Engineering)
