The current logic only allows lock stealing to occur if the current task

This is a pair of Xen para-virtual frontend device drivers:
drivers/video/xen-fbfront.c provides a framebuffer, and
drivers/input/xen-kbdfront provides keyboard and mouse.
The backends run in dom0 user space.
The two drivers are not in two separate patches, because the

Deferred I/O was utterly broken. Reading the mmap()ed framebuffer
worked, but writing it made the VM endlessly invoke
vm_ops.page_mkwrite(). That happened because we failed to set
page->mapping and page->index.
The fix is to set them, and clean up properly before the framebuffer
gets released.
Frontends are expected to write their protocol ABI to xenstore. Since
the protocol ABI defaults to the backend's native ABI, things work
fine without that as long as the frontend's native ABI is identical to
the backend's native ABI. This is not the case for xen-blkfront

PIT_TICK_RATE is overriden specificaly for R321x in include/asm-x86/timex.h,
just like for AMD Elan.

Damn! I remembered to reread to body of the mail and forgot
The early exception handlers are currently set up using a macro
recursion. Replace that with a standard loop.
Noop patch, just a cleanup.

All of early setup runs with interrupts disabled, so there is no
need to set up early exception handlers for vectors >= 32
That saves some text size

Currently they are in .text.head because the rest of head_64.S.
.text.head is not removed as init data, but the early exception handlers
should be because they are not needed after early boot of the BP.
So move them over.

I think it can boot already, will tell you when I have done the necessary
testing.
