clang sometimes decides not to inline shuffle_zone(), but it calls a
__meminit function. Without the extra __meminit annotation we get this
warning:
WARNING: modpost: vmlinux.o(.text+0x2a86d4): Section mismatch in reference from the function shuffle_zone() to the function .meminit.text:__shuffle_zone()
The function shuffle_zone() references
the function __meminit __shuffle_zone().
This is often because shuffle_zone lacks a __meminit
annotation or the annotation of __shuffle_zone is wrong.
shuffle_free_memory() did not show the same problem in my tests, but it
could happen in theory as well, so mark both as __meminit.

When multiple PCI devices get assigned to a guest right at boot, libxl
incrementally populates the backend tree. The writes for the first of
the devices trigger the backend watch. In turn xen_pcibk_setup_backend()
will set the XenBus state to Initialised, at which point no further
reconfigures would happen unless a device got hotplugged. Arrange for
reconfigure to also get triggered from the backend watch handler.

The commit referenced below was incomplete: It merely affected what
would get written to the vdev-<N> xenstore node. The guest would still
find the function at the original function number as long as
__xen_pcibk_get_pci_dev() wouldn't be in sync. The same goes for AER wrt
__xen_pcibk_get_pcifront_dev().
Undo overriding the function to zero and instead make sure that VFs at
function zero remain alone in their slot. This has the added benefit of
improving overall capacity, considering that there's only a total of 32
slots available right now (PCI segment and bus can both only ever be
zero at present).

xen_setup_gdt(), via xen_load_gdt_boot(), wants to adjust page tables.
For this to work when NX is not available, x86_configure_nx() needs to
be called first.
[jgross] Note that this is a revert of 36104cb9012a82e73 ("x86/xen:
Delay get_cpu_cap until stack canary is established"), which is possible
now that we no longer support running as PV guest in 32-bit mode.

sc->ip is the inode that's being scrubbed, which means that it's not set
for scrub types that don't involve inodes. If one of those scrubbers
(e.g. inode btrees) returns EDEADLOCK, we'll trip over the null pointer.

If a realtime allocation fails because we can't find a sufficiently
large free extent satisfying locality rules, relax the locality rules
and try again. This reduces the occurrence of short writes to realtime
files when the write size is large and the free space is fragmented.
This was originally discovered by running generic/186 with the realtime
reflink patchset and a 128k cow extent size hint, but the short write
symptoms can manifest with a 128k extent size hint and no reflink, so
apply the fix now.

As an artifact of how gendisk lookup used to work in earlier kernels,
GENHD_FL_UP is only cleared very late in del_gendisk, and a global lock
is used to prevent opens from succeeding while del_gendisk is tearing
down the gendisk. Switch to clearing the flag early and under bd_mutex
so that callers can use bd_mutex to stabilize the flag, which removes
the need for the global mutex.

When multiple processes write data to the same block group on a
compressed zoned filesystem, the underlying device could report I/O
errors and data corruption is possible.
This happens because on a zoned file system, compressed data writes
where sent to the device via a REQ_OP_WRITE instead of a
REQ_OP_ZONE_APPEND operation. But with REQ_OP_WRITE and parallel
submission it cannot be guaranteed that the data is always submitted
aligned to the underlying zone's write pointer.
The change to using REQ_OP_ZONE_APPEND instead of REQ_OP_WRITE on a
zoned filesystem is non intrusive on a regular file system or when
submitting to a conventional zone on a zoned filesystem, as it is
guarded by btrfs_use_zone_append.

btrfs_use_zone_append only needs the passed in extent_map's block_start

This also enables the use of btrfs_use_zone_append in places where we only
have a start byte but no extent_map.

It is not needed because there is an existing lock open_file_lock to achieve
the same. find_readable_file takes open_file_lock and then traverses the
openFileList. Similarly, cifs_oplock_break while closing the deferred

When PAGE_SIZE is larger than AMDGPU_PAGE_SIZE, the number of GPU TLB
entries which need to update in amdgpu_map_buffer() should be multiplied
by AMDGPU_GPU_PAGES_IN_CPU_PAGE (PAGE_SIZE / AMDGPU_PAGE_SIZE).

[why]
As per spec, DCN3.x can do 6:1 downscaling and DCN2.x can do 4:1. The
max downscaling limit value for DCN2.x is 250, which means it's
calculated as 1000 / 4 = 250. For DCN3.x this then gives 1000 / 6 = 167.
[how]
Set maximum downscaling limit to 167 for DCN3.x

This reverts commit b12d691ea5e01db42ccf3b4207e57cb3ce7cfe91.
It turns out this is not ready for primetime yet. The intentions are
good, but using remap_pfn_range() requires that there is nothing already
mapped in the area, and the i915 code seems to very much intentionally
remap the same area multiple times.
That will then just trigger the
BUG_ON(!pte_none(*pte));
in mm/memory.c: remap_pte_range().
There are also reports of mapping type inconsistencies, resulting in
warnings and in screen corruption.

The initialization of MIDI devices that are found on some LINE6
drivers are currently done in a racy way; namely, the MIDI buffer
instance is allocated and initialized in each private_init callback
while the communication with the interface is already started via
line6_init_cap_control() call before that point. This may lead to
Oops in line6_data_received() when a spurious event is received, as
reported by syzkaller.
This patch moves the MIDI initialization to line6_init_cap_control()
as well instead of the too-lately-called private_init for avoiding the
race. Also this reduces slightly more lines, so it's a win-win
change.

Commit 871f1f2bcb01 ("platform/x86: intel_int0002_vgpio: Only implement
irq_set_wake on Bay Trail") stopped passing irq_set_wake requests on to
the parents IRQ because this was breaking suspend (causing immediate
wakeups) on an Asus E202SA.
This workaround for the Asus E202SA is causing wakeup by USB keyboard to
not work on other devices with Airmont CPU cores such as the Medion Akoya
E1239T. In hindsight the problem with the Asus E202SA has nothing to do
with Silvermont vs Airmont CPU cores, so the differentiation between the
2 types of CPU cores introduced by the previous fix is wrong.
The real issue at hand is s2idle vs S3 suspend where the suspend is
mostly handled by firmware. The parent IRQ for the INT0002 device is shared
with the ACPI SCI and the real problem is that the INT0002 code should not
be messing with the wakeup settings of that IRQ when suspend/resume is
being handled by the firmware.
Note that on systems which support both s2idle and S3 suspend, which
suspend method to use can be changed at runtime.
This patch fixes both the Asus E202SA spurious wakeups issue as well as
the wakeup by USB keyboard not working on the Medion Akoya E1239T issue.
These are both fixed by replacing the old workaround with delaying the
enable_irq_wake(parent_irq) call till system-suspend time and protecting
it with a !pm_suspend_via_firmware() check so that we still do not call
it on devices using firmware-based (S3) suspend such as the Asus E202SA.
Note rather then adding #ifdef CONFIG_PM_SLEEP, this commit simply adds
a "depends on PM_SLEEP" to the Kconfig since this drivers whole purpose
is to deal with wakeup events, so using it without CONFIG_PM_SLEEP makes
no sense.

The virtio framework uses wmb() when updating avail->idx. It
guarantees the write order, but not necessarily loading order
for the code accessing the memory. This commit adds a load barrier
after reading the avail->idx to make sure all the data in the
descriptor is visible. It also adds a barrier when returning the
packet to virtio framework to make sure read/writes are visible to
the virtio code.

The poll function should not return -ERESTARTSYS.
Furthermore, locking in this function is completely unnecessary. The
ddev->lock protects access to the main device and controller (ddev->dev
and ddev->ctrl), ensuring that both are and remain valid while being
accessed by clients. Both are, however, never accessed in the poll
function. The shutdown test (via atomic bit flags) be safely done
without locking, so drop locking here entirely.
