Added reference counting mechanism for XRC target QPs between
ib_uqp_object and its ib_uxrcd_object. This prevents closing an XRC

PCI core will initialize device MSI/MSI-X capability in

MSI/MSI-X instead of using pci_find_capability(pci_dev,
PCI_CAP_ID_MSI/MSIX). Access to PCIe device config space again will

1. The code accepts chunks of messages, and splits the chunk into
packets when converting packets into sdma queue entries. Adjacent
packets will use user buffer pages smartly to avoid pinning the
same page multiple times.
2. Instead of discarding all the work when SDMA queue is full, the
work is saved in a pending queue. Whenever there are enough SDMA
queue free entries, pending queue is directly put onto SDMA queue.
3. An interrupt handler is used to progress this pending queue.

Signed-off-by: Roland Dreier <roland@purestorage.com>
Tegra20 HW appears to have a bug such that PCIe device interrupts,
whether they are legacy IRQs or MSI, are lost when LP2 is enabled. To
work around this, simply disable LP2 if any PCIe devices with interrupts
are present. Detect this via the IRQ domain map operation. This is
slightly over-conservative; if a device with an interrupt is present but
the driver does not actually use them, LP2 will still be disabled.
However, this is a reasonable trade-off which enables a simpler
workaround.

The ISP clock registers belong to the ISP power domain and may change
their values if this power domain is switched off/on. Add
CLK_GET_RATE_NOCACHE flags to ensure we do not rely on invalid cached
data when setting or getting frequency of those clocks.
Without this fix the FIMC-IS Cortex-A5 core and AXI bus clocks have
incorrect frequencies, which breaks the ISP operation and starting the
video pipeline fails with timeouts reported by the FIMC-IS firmware.

This is only theoretical, but after try_to_wake_up(p) was changed
to check p->state under p->pi_lock the code like
__set_current_state(TASK_INTERRUPTIBLE);
schedule();
can miss a signal. This is the special case of wait-for-condition,
it relies on try_to_wake_up/schedule interaction and thus it does
not need mb() between __set_current_state() and if(signal_pending).
However, this __set_current_state() can move into the critical
section protected by rq->lock, now that try_to_wake_up() takes
another lock we need to ensure that it can't be reordered with
"if (signal_pending(current))" check inside that section.
The patch is actually one-liner, it simply adds smp_wmb() before
spin_lock_irq(rq->lock). This is what try_to_wake_up() already
does by the same reason.
We turn this wmb() into the new helper, smp_mb__before_spinlock(),
for better documentation and to allow the architectures to change
the default implementation.
While at it, kill smp_mb__after_lock(), it has no callers.
Perhaps we can also add smp_mb__before/after_spinunlock() for
prepare_to_wait().

Some platforms (e.g S390) don't use the generic hardirqs code and
therefore do not defined HAVE_GENERIC_HARDIRQS. This prevents using
the irq_set_chip_data() and irq_get_chip_data() functions that are
used for the default implementations of the MSI operations.
So, when CONFIG_GENERIC_HARDIRQS is not enabled, provide another
default implementation of the MSI operations, that simply errors
out. The architecture is responsible for implementing those operations
(which is the case on S390), and cannot use the msi_chip infrastructure.

in cgroup_css() and convert all assignments to either
rcu_assign_pointer() or RCU_INIT_POINTER().
This change prepares for the actual RCUfication of css's and doesn't

For the planned unified hierarchy, each css (cgroup_subsys_state) will
be RCU protected so that it can be created and destroyed individually
while allowing RCU accesses, and cgroup_css() will soon require either
holding cgroup_mutex or RCU read lock.
This patch updates cgroup_file_open() such that it acquires the
associated css under rcu_read_lock(). While cgroup_file_css() usages
in other file operations are safe due to the reference from open,
cgroup_css() wouldn't know that and will still trigger warnings. It'd
be cleanest to store the acquired css in file->prvidate_data for
further file operations but that's already used by seqfile. This
patch instead adds cfent->css to cache the associated css. Note that
while this field is initialized during cfe init, it should only be
considered valid while the file is open.

With the planned unified hierarchy, css's (cgroup_subsys_state) will
be RCU protected and allowed to be attached and detached dynamically
over the course of a cgroup's lifetime. This means that css's will
stay accessible after being detached from its cgroup - the matching
pointer in cgroup->subsys[] cleared - for ref draining and RCU grace
period.
cgroup core still wants to guarantee that the parent css is never
destroyed before its children and css_parent() always returns the
parent regardless of the state of the child css as long as it's
accessible.
This patch makes css's hold onto their parents and adds css->parent so
that the parent css is never detroyed before its children and can be
determined without consulting the cgroups.
cgroup->dummy_css is also updated to point to the parent dummy_css;
however, it doesn't need to worry about object lifetime as the parent
cgroup is already pinned by the child.
