kaf24@scramble.cl.cam.ac.uk 3ef3ee4b43 bitkeeper revision 1.1159.199.1 (41ab4412dnDymGEqZNhEzt67Yzgmxw) 
MTRR support for privileged kernels. Should help our X-server support.

kaf24@scramble.cl.cam.ac.uk b582b9903a bitkeeper revision 1.1159.187.33 (41ab10f0GLXR1qCvGRT8TTbIpm5j7A) 
Fix ioremap() to only expect the lowmem ISA region to be fixmap()ed
in privileged builds.

Pull Linux MTRR driver into Xen. This ensures that MTRRs are consistent
across all CPUs at boot time. We still need to export MTRR setting via
the control interface, and virtualise the XenLinux MTRR driver.

Get rid of all our uses of virt_to_phys():
 1. Many were buggy, so the code needed fixing or clarifying anyway
 2. It means we can now experiment with kludging virt_to_phys() to be
    the same as virt_to_bus(), to get more buggy drivers working. I haven't
    included the kludge in this patch.

Update the AGP+DRM patches for 2.6.9, and automatically patch the kernels
before we build them. Also avoid using virt_to_phys() in our virtual drivers
as we may change what it does -- better to use __pa().

kaf24@scramble.cl.cam.ac.uk e97d12ad95 bitkeeper revision 1.1159.187.27 (41a99261iejadhs-BVt7TOiimzafww) 
Fix IOPL handling.
 1. Both Linux 2.4 and 2.6 were not correctly setting IOPL during context
    switch (they sent a bogus dom0_op with a bad version number).
 2. The switch_vm86 hypercall was corrupting EFLAGS and setting IOPL==0.

We must load shared_info into %esi at every external entry point into 
entry.S (i.e., every label marked ENTRY()). I was missing at least
resume_userspace which is essential for vm86.

entry.S. Also fix tabbing in failsafe_callback.

Small vm86 fix. vm86 mode still crashes Linux.

kaf24@scramble.cl.cam.ac.uk e5e283215b bitkeeper revision 1.1159.187.22 (41a89729VHxMK8Tp4qcLrOPCoZrdog) 
First cut for VM86 support, based on Stephan Diestelhorst's patches. It
doesn't actually work yet -- it's possible that e.g., signal delivery is
broken.

kaf24@scramble.cl.cam.ac.uk 3962da061e bitkeeper revision 1.1159.187.21 (41a85113PA1gYVqMumQ4r2S3y6POGw) 
Clean up and fix the 2.6 entry.S:
 1. Save and restore the event_mask in SAVE_ALL / restore_all.
 2. No need to keep reloading %esi all oevr the place as we can load it
    once on entry (e.g., SAVE_ALL) and thereafter it is callee-saves.
 3. No need for extra XEN_UNBLOCK_EVENTS() where native isn't doing a 'sti',
    even if the code looks broken -- it is okay to call schedule() with 
    interrupts off, in which case it will reenable them itself.
 4. Fixed another KERNEL_DS -> USER_DS.
 5. Unmacroed the page fault handler.
 6. A bunch of other tiny fixes....

kaf24@scramble.cl.cam.ac.uk d865fcaa3f bitkeeper revision 1.1159.187.20 (41a77433rez_BGuifdBbTI3Y34kiag) 
Deal with exception from guest context with real interrupts disabled.
This can happen because IOPL != 0 and even a well-behaved guest may
execute random BIOS code if it is a privileged hardware-controlling
domain (e.g., DOM0 X server).

foreigndom across preempt/resume.
