v9fs may be used as lower layer of overlayfs and accessing f_path.dentry
can lead to a crash. In this case it's a NULL pointer dereference in
p9_fid_create().
Fix by replacing direct access of file->f_path.dentry with the
file_dentry() accessor, which will always return a native object.

I hit a bug when running test suite without forking each test (-F
option):
$ perf test -Fv
...
34: Test thread map :
--- start ---
FAILED tests/thread-map.c:24 wrong comm
---- end ----
Test thread map: FAILED!
The reason was the process name wasn't 'perf' as expected by the test,
because other tests set the name as well.
Setting it explicitly now.

Commit d6a9996e84ac ("powerpc/mm: vmalloc abstraction in preparation for
radix") turned kernel memory and IO addresses from #defined constants to
variables initialised at runtime.
On PA6T (pasemi) systems the setup_arch() machine call initialises the
onboard PCI-e root-ports, and uses pci_io_base to do this, which is now
before its value has been set, resulting in a panic early in boot before
console IO is initialised.
Move the pci_io_base initialisation to the same place as vmalloc ranges
are set (hash__early_init_mmu()/radix__early_init_mmu()) - this is the
earliest possible place we can initialise it.

When configuring FPS during probe, assuming a DT node is present for
FPS, the code can run into a problem with the switch statements in
max77620_config_fps() and max77620_get_fps_period_reg_value(). Namely,
in the case of chip->chip_id == MAX77620, it will set
fps_[mix|max]_period but then fall through to the default switch case
and return -EINVAL. Returning this from max77620_config_fps() will
cause probe to fail.

Phasing out generic reset line requests enables us to make some better
decisions on when and how to (de)assert said lines. If an 'exclusive'
line is requested, we know a device *requires* a reset and that it's
preferable to act upon a request right away. However, if a 'shared'
reset line is requested, we can reasonably assume sure that placing a
device into reset isn't a hard requirement, but probably a measure to
save power and is thus able to cope with not being asserted if another
device is still in use.
In order allow gentle adoption and not to forcing all consumers to
move to the API immediately, causing administration headache between
subsystems, this patch adds some temporary stand-in shim-calls. This
will ease the burden at merge time and allow subsystems to migrate over
to the new API in a more realistic time-frame.

We're about to split the current API into two, where consumers will
be forced to be explicit when requesting reset lines. The choice
will be to either the call the *_exclusive or *_shared variant
depending on whether they can actually tolorate not being asserted
when that request is made.
The new API will look like this once reorded and complete:
reset_control_get_exclusive()
reset_control_get_shared()
reset_control_get_optional_exclusive()
reset_control_get_optional_shared()
of_reset_control_get_exclusive()
of_reset_control_get_shared()

SD4 regulator is not registered with regulator core
framework in probe as there is no support in MAX77620 PMIC,
removing SD4 entry from MAX77620 regulator information list
and checking for valid regulator information data before
configuring FPS source and FPS power up/down period to avoid
NULL pointer exception if regulator not registered with core.

1. Populate correct value of VDDCI voltage for SMC SAMU, VCE,
and UVD levels depending on whether VDDCi control is SVI2 or GPIO.
2. Populate SMC ACPI minimum voltage using VBIOS boot SCLK and MCLK
When static voltage is configured as VDDCI, driver still tries to program
a voltage for MM minVoltage using VDDC-VDDCI delta requirement.
minVoltage should be set as boot up voltage.

Only the first and last netlink message for a particular conntrack are
actually sent. The first message is sent through nf_conntrack_confirm when
the conntrack is committed. The last one is sent when the conntrack is
destroyed on timeout. The other conntrack state change messages are not
advertised.
When the conntrack subsystem is used from netfilter, nf_conntrack_confirm
is called for each packet, from the postrouting hook, which in turn calls
nf_ct_deliver_cached_events to send the state change netlink messages.
This commit fixes the problem by calling nf_ct_deliver_cached_events in the
non-commit case as well.

SPQ doorbell is currently protected with the compilation barrier. Under the
stress scenarios, we may get into a state where (due to the weak ordering)
several ramrod doorbells were written to the BAR with an out-of-order
producer values. Need to change the barrier type to a write barrier to make
sure that the write buffer is flushed after each doorbell.

neigh_xmit() expects to be called inside an RCU-bh read side critical
section, and while one of its two current callers gets this right, the
other one doesn't.
More specifically, neigh_xmit() has two callers, mpls_forward() and
mpls_output(), and while both callers call neigh_xmit() under
rcu_read_lock(), this provides sufficient protection for neigh_xmit()
only in the case of mpls_forward(), as that is always called from
softirq context and therefore doesn't need explicit BH protection,
while mpls_output() can be called from process context with softirqs
enabled.
When mpls_output() is called from process context, with softirqs
enabled, we can be preempted by a softirq at any time, and RCU-bh
considers the completion of a softirq as signaling the end of any
pending read-side critical sections, so if we do get a softirq
while we are in the part of neigh_xmit() that expects to be run inside
an RCU-bh read side critical section, we can end up with an unexpected
RCU grace period running right in the middle of that critical section,
making things go boom.
This patch fixes this impedance mismatch in the callee, by making
neigh_xmit() always take rcu_read_{,un}lock_bh() around the code that
expects to be treated as an RCU-bh read side critical section, as this
seems a safer option than fixing it in the callers.
