  Without dirfd it may be indeed problematic for containers. So let's

  that we have more time to mull over how to best specify the filesystem
  we want to work on"

Pull mount_setattr fix from Christian Brauner:
 "This makes an underlying idmapping assumption more explicit.

  We currently don't have any filesystems that support idmapped mounts
  which are mountable inside a user namespace, i.e. where s_user_ns !=
  init_user_ns. That was a deliberate decision for now as userns root
  can just mount the filesystem themselves.

  real use-case for this. This way we can notice it and will have a

  appropriately if we need to support such filesystems"

This reverts commit b12d691e.

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.

Commit 871f1f2b ("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 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.

In commit fa8b9007 ("quota: wire up quotactl_path") we have wired up

objected that the path based syscall is missing dirfd and flags argument

they have a point and after a discussion with Christian Brauner and
Sascha Hauer I've decided to disable the syscall for now and update its
API. Since there is no userspace currently using that syscall and it
hasn't been released in any major release, we should be fine.

 - A couple more minor fixes.

 "This mainly fixes 1 lcluster-sized pclusters for the big pcluster

  Also, documentation updates are included to fix the broken
  illustration due to the ReST conversion by accident and complete the
  big pcluster introduction.

  Summary:

   - update documentation to fix the broken illustration due to ReST
     conversion by accident at that time and complete the big pcluster
