Make cputime_t and cputime64_t nocast to enable sparse checking to
detect incorrect use of cputime. Drop the cputime macros for simple

mmc_suspend_host() tries to claim host during suspend
and release it only when the bus suspend operation is
compeleted. If CONFIG_MMC_UNSAFE_RESUME is defined and
the host is flagged as removable, mmc_suspend_host()
tries to remove the card. In this process, the file system
sync can get blocked trying to acquire host which is already
claimed by mmc_suspend_host() causing deadlock.
Fix this deadlock by releasing host before ->remove() is called.

Adds a quirk that sets the data read timeout to a fixed value instead
of relying on the information in the CSD. The timeout value chosen
is 300ms since that has proven enough for the problematic cards found,
but could be increased if other cards require this.
This patch also enables this quirk for certain Micron cards known to
have this problem.

Once a device is failed we really want to completely ignore it.
It should go away soon anyway.
In particular the presence of bad blocks on it should not cause us to
block as we won't be trying to write there anyway.
So as soon as we can check if a device is Faulty, do so and pretend
that it is already gone if it is Faulty.

When we mark blocks as bad we need them to be acknowledged by the
metadata handler promptly.
For an in-kernel metadata handler that was already being done. But
for an external metadata handler we need to alert it of the change by
sending a notification through the sysfs file. This adds that
notification.

Once a device is marked Faulty the badblocks - whether acknowledged or
not - become irrelevant. So they shouldn't cause the device to be
marked as Blocked.
Without this patch, a process might write "-blocked" to clear the
Blocked status, but while that will correctly fail the device, it
won't remove the apparent 'blocked' status.

When we are accessing an mddev via sysfs we know that the
mddev cannot disappear because it has an embedded kobj which
is refcounted by sysfs.
And we also take the mddev_lock.
However this is not enough.
The final mddev_put could have been called and the
mddev_delayed_delete is waiting for sysfs to let go so it can destroy
the kobj and mddev.
In this state there are a lot of changes that should not be attempted.
To to guard against this we:
- initialise mddev->all_mddevs in on last put so the state can be
easily detected.
- in md_attr_show and md_attr_store, check ->all_mddevs under
all_mddevs_lock and mddev_get the mddev if it still appears to
be active.
This means that if we get to sysfs as the mddev is being deleted we
will get -EBUSY.
rdev_attr_store and rdev_attr_show are similar but already have
sufficient protection. They check that rdev->mddev still points to
mddev after taking mddev_lock. As this is cleared before delayed
removal which can only be requested under the mddev_lock, this
ensure the rdev and mddev are still alive.

We like md devices to disappear when they really are not needed.
However it is not possible to tell from the current state whether it
is needed or not. We can only tell from recent history of changes.
In particular immediately after we create an md device it looks very
similar to immediately after we have finished with it.
So we always preserve a newly created md device until something
significant happens. This state is stored in 'hold_active'.
The normal case is to keep it until an ioctl happens, as that will
normally either activate it, or explicitly de-activate it. If it
doesn't then it was probably created by mistake and it is now time to
get rid of it.
We can also modify an array via sysfs (instead of via ioctl) and we
currently treat any change via sysfs like an ioctl as a sign that if
it now isn't more active, it should be destroyed.
However this is not appropriate as changes made via sysfs are more
gradual so we should look for a more definitive change.
So this patch only clears 'hold_active' from UNTIL_IOCTL to clear when
the array_state is changed via sysfs. Other changes via sysfs
are ignored.

* 'pm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:
PM / Driver core: leave runtime PM enabled during system shutdown
|
|
Disabling all runtime PM during system shutdown turns out not to be a
good idea, because some devices may need to be woken up from a
low-power state at that time.
The whole point of disabling runtime PM for system shutdown was to
prevent untimely runtime-suspend method calls. This patch (as1504)
accomplishes the same result by incrementing the usage count for each
device and waiting for ongoing runtime-PM callbacks to finish. This
is what we already do during system suspend and hibernation, which
makes sense since the shutdown method is pretty much a legacy analog
of the pm->poweroff method.
This fixes a recent regression on some OMAP systems introduced by
commit af8db1508f2c9f3b6e633e2d2d906c6557c617f9 (PM / driver core:
disable device's runtime PM during shutdown).

PPC32/64 defines NO_IRQ to zero, so no problems expected.
ARM defines NO_IRQ to -1, but OF code relies on IRQ domains support,
which returns correct ('0') value in 'no irq' case. So everything
should be fine.
Other arches might break if some of their OF drivers rely on NO_IRQ
being not 0. If so, the drivers must be fixed, finally.

The recursion loop goes retire_requests->unbind->gpu_idle->retire_reqeusts.
Every time we go through this we need a
- active object that can be retired
- and there are no other references to that object than the one from
the active list, so that it gets unbound and freed immediately.
Otherwise the recursion stops. So the recursion is only limited by the
number of objects that fit these requirements sitting in the active list
any time retire_request is called.
Issue exercised by tests/gem_unref_active_buffers from i-g-t.
There's been a decent bikeshed discussion whether it wouldn't be
better to pass around a flag, but imo this is o.k. for such a limited
case that only supports a w/a.

If an attribute is present (but not yet supported) it should be OK
to write 0 (a no-op) to the attribute.
This is an issue because userspace should be able to save and restore all
set attribute values without error.

So the code assumes that the sg list is only a array while in reality
loopback SGL memory via scsi_cmnd into target-core may be already
chained. This patch converts ramdisk code to use sg_miter logic from
scatterlist.h in order to properly support passthrough SGL usage with
transport_generic_map_mem_to_cmd() via loopback.
With this patch the bug goes away. However after umount/mount of the
device my files are gone. So something is still not right. After looking
at it for a while I decided to rewrite the that part of the code and now
things do work for me.
