When we are dumping the router ports of a vlan mcast context we need to
use the bridge/vlan and port/vlan's multicast contexts to check if
IPv4/IPv6 router port is present and later to dump the vlan id.

net: ipa: use runtime PM reference counting
This series does further rework of the IPA clock code so that we
rely on some of the core runtime power management code (including
its referencing counting) instead.
The first patch makes ipa_clock_get() act like pm_runtime_get_sync().
The second patch makes system suspend occur regardless of the
current reference count value, which is again more like how the
runtime PM core code behaves.
The third patch creates functions to encapsulate all hardware
suspend and resume activity. The fourth uses those functions as
the ->runtime_suspend and ->runtime_resume power callbacks. With
that in place, ipa_clock_get() and ipa_clock_put() are changed to
use runtime PM get and put functions when needed.
The fifth patch eliminates an extra clock reference previously used
to control system suspend. The sixth eliminates the "IPA clock"
reference count and mutex.
The final patch replaces the one call to ipa_clock_get_additional()
with a call to pm_runtime_get_if_active(), making the former
unnecessary.
====================

Now that ipa_clock_get_additional() is a trivial wrapper around

The runtime power management core code maintains a usage count. This
count mirrors the IPA clock reference count, and there's no need to
maintain both. So get rid of the IPA clock reference count and just
rely on the runtime PM usage count to determine when the hardware
should be suspended or resumed.
Use pm_runtime_get_if_active() in ipa_clock_get_additional(). We
care whether power is active, regardless of whether it's in use, so
pass true for its ign_usage_count argument.
The IPA clock mutex is just used to make enabling/disabling the
clock and updating the reference count occur atomically. Without
the reference count, there's no need for the mutex, so get rid of
that too.

Suspending the IPA hardware is now managed by the runtime PM core
code. The ->runtime_idle callback returns a non-zero value, so it
will never suspend except when forced. As a result, there's no need
to take an extra "do not suspend" clock reference.
Signed-off-by: Alex Elder <elder@linaro.org>
Signed-off-by: David S. Miller <davem@davemloft.net>
Use the runtime power management core to cause hardware suspend and
resume to occur. Enable it in ipa_clock_init() (without autosuspend),
and disable it in ipa_clock_exit().
Use ipa_runtime_suspend() as the ->runtime_suspend power operation,
and arrange for it to be called by having ipa_clock_get() call
pm_runtime_get_sync() when the first clock reference is taken.
Similarly, use ipa_runtime_resume() as the ->runtime_resume power
operation, and pm_runtime_put() when the last IPA clock reference
is dropped.
Introduce ipa_runtime_idle() as the ->runtime_idle power operation,
and have it return a non-zero value; this way suspend will never
occur except when forced.
Use pm_runtime_force_suspend() and pm_runtime_force_resume() as the
system suspend and resume callbacks, and remove ipa_suspend() and
ipa_resume().
Store a pointer to the device structure passed to ipa_clock_init(),
so it can be used by ipa_clock_exit() to disable runtime power
management.
For now we preserve IPA clock reference counting.
Signed-off-by: Alex Elder <elder@linaro.org>
Signed-off-by: David S. Miller <davem@davemloft.net>
Introduce ipa_runtime_suspend() and ipa_runtime_resume(), which
encapsulate the activities necessary for suspending and resuming
the IPA hardware. Call these functions from ipa_clock_get() and
ipa_clock_put() when the first reference is taken or last one is
dropped.
When the very first clock reference is taken (for ipa_config()),
setup isn't complete yet, so (as before) only the core clock gets
enabled.
When the last clock reference is dropped (after ipa_deconfig()),
ipa_teardown() will have made the setup_complete flag false, so
there too, the core clock will be stopped without affecting GSI
or the endpoints.
Otherwise these new functions will perform the desired suspend and
resume actions once setup is complete.

Disable the IPA clock rather than dropping a reference to it in the
system suspend callback. This forces the suspend to occur without
affecting existing references.
Similarly, enable the clock rather than taking a reference in
ipa_resume(), forcing a resume without changing the reference count.

We currently assume no errors occur when enabling or disabling the
IPA core clock and interconnects. And although this commit exposes
errors that could occur, we generally assume this won't happen in
practice.
This commit changes ipa_clock_get() and ipa_clock_put() so each
returns a value. The values returned are meant to mimic what the
runtime power management functions return, so we can set up error
handling here before we make the switch. Have ipa_clock_get()
increment the reference count even if it returns an error, to match
the behavior of pm_runtime_get().
More details follow.
When taking a reference in ipa_clock_get(), return 0 for the first
reference, 1 for subsequent references, or a negative error code if
an error occurs. Note that if ipa_clock_get() returns an error, we
must not touch hardware; in some cases such errors now cause entire
blocks of code to be skipped.
When dropping a reference in ipa_clock_put(), we return 0 or an
error code. The error would come from ipa_clock_disable(), which
now returns what ipa_interconnect_disable() returns (either 0 or a
negative error code). For now, callers ignore the return value;
if an error occurs, a message will have already been logged, and
little more can actually be done to improve the situation.

For normal system, the dma_addr[1] in 'struct page' is not

which means how many frags this page might be splited to.
In order to simplify the page frag support in the page pool,
the PAGE_POOL_DMA_USE_PP_FRAG_COUNT macro is added to indicate
the 32 bit systems with 64 bit dma, and the page frag support
in page pool is disabled for such system.
The newly added page_pool_set_frag_count() is called to reserve
