Hello,
This series contains an assorted set of fixes and improvements for
the Xen para-virtualized display driver and grant device driver which
I have collected over the last couple of months:
1. Minor fixes to grant device driver and drm/xen-front.
2. New format
From: Oleksandr Andrushchenko
This is the sync up with the canonical definition of the
display protocol in Xen.
1. Add protocol version as an integer

code that supports different protocol versions. To simplify that
also add t

While importing a dmabuf it is possible that the data of the buffer

The patch c575b7eeb89f: "drm/xen-front: Add support for Xen PV

checker warning:

From: Oleksandr Andrushchenko
It is possible that the scatter-gather table during dmabuf import has
non-zero offset of the data, but user-space doesn't expect that.
Fix this by failing the import, so user-space doesn't access wrong data.

From: Alexander Duyck
We can drop the need for the locked variable by making use of the
lruvec_holds_page_lru_lock function. By doing this we can avoid some rcu
locking ugliness for the case where the lruvec is still holding the LRU
lock associated with the page. Instead we can just use the lruve
From: Alexander Duyck
The only user of test_and_set_skip was isolate_migratepages_block and it
was using it after a call that was testing and clearing the LRU flag. As
such it really didn't need to be behind the LRU lock anymore as it wasn't
really fulfilling its purpose.
With that being the cas
From: Alexander Duyck
Since we are holding a reference to the page much sooner in
isolate_migratepages_block we could move the PageCompound check out of the
LRU locked section and instead just place it after get_page_unless_zero. By
doing this we can allow any of the items that might trigger a fa

Broadcast mode bonds transmit a copy of all traffic simultaneously out of
all interfaces, so the "speed" of the bond isn't really the aggregate of
all interfaces, but rather, the speed of the lowest active interface.
Also, the type of the speed field is u32, not unsigned long, so adjust

The lowmem_reserve arrays provide a means of applying pressure
against allocations from lower zones that were targeted at
higher zones. Its values are a function of the number of pages
managed by higher zones and are assigned by a call to the
setup_per_zone_lowmem_reserve() function.
