A huge pud page can theoretically be faulted in racing with pmd_alloc()
in __handle_mm_fault(). That will lead to pmd_alloc() returning an
invalid pmd pointer. Fix this by adding a pud_trans_unstable() function
similar to pmd_trans_unstable() and check whether the pud is

You're failing to explain how we get here in the first place.

It happens before with debug objects. It might not 100% necessary but it could
easily end up with this way in the current code. Moreover, this is just an
example of how

For users that want to travers all page table entries pointing into a
region of a struct address_space mapping, introduce a walk_page_mapping()
function.
The walk_page_mapping() function will be initially be used for dirty-
tracking in virtual graphics drivers.

The pagewalk code was unconditionally splitting transhuge pmds when a
pte_entry was present. However ideally we'd want to handle transhuge pmds
in the pmd_entry function and ptes in pte_entry function. So don't split
huge pmds when there is a pmd_entry function present,

With emulated coherent memory we need to be able to quickly look up
a resource from the MOB offset. Instead of traversing a linked list with
O(n) worst case, use an RBtree with O(log n) worst case complexity.

Add the callbacks necessary to implement emulated coherent memory for
surfaces. Add a flag to the gb_surface_create ioctl to indicate that
surface memory should be coherent.
Also bump the drm minor version to signal the availability of coherent
surfaces.

Without the lock, anybody modifying a pte from within this function might

Add two utilities to 1) write-protect and 2) clean all ptes pointing into
a range of an address space.
The utilities are intended to aid in tracking dirty pages (either
