So, in the dso__load_sym, dso is gotten 3 times, by dso__new,
map__new2, and dsos__add. The last 2 is actually released by
map_groups and machine__delete correspondingly. However, the
first reference by dso__new, is never released.
Committer note:
Changed the place where the reference count is dropped to:
Fix it by dropping it right after creating curr_map, since we know that
either that operation failed and we need to drop the dso refcount or
that it succeed and we have it referenced via curr_map->dso.
Then only drop the curr_map refcount after we call dsos__add() to make
sure we hold a reference to it via curr_map->dso.

Mainly aux communications on sink_crc
were failing a lot randomly on recent platforms.
The first solution was to try to use intel_dp_dpcd_read_wake, but then
it was suggested to move retries to drm level.
Since drm level was already taking care of retries and didn't want
to through random retries on that level the second solution was to
put the retries at aux_transfer layer what was nacked.
So I realized we had so many retries in different places and
started to organize that a bit. During this organization I noticed
that we weren't handing at all the case were the message size was
zeroed. And this was exactly the case that was affecting sink_crc.
Also we weren't respect BSPec who says this size message = 0 or > 20
are forbidden.
It is a fact that we still have no clue why we are getting this
forbidden value there. But anyway we need to handle that for now
so we return -EBUSY and drm level takes care of the retries that
are already in place.
v2: Print debug messsage when this case is reached as suggested
by Jani.
v3: This patch is crucial to make PSR test cases reliably working
on SKL. So split this patch from the aux re-org series and add
a FIXME as a promisse to continue that effort besides reminding
to remove the sleep when that is merged.
v4: Use a bigger usleep range so kernel doesn't need to be interrupted
on a exact time, as suggested by Paulo.
But anyway we should discuss the better time
ranges on the EBUSY handle re-org at drm level since this one here
is temporary.

After sample processing is done, hist entries are in both of
hists->entries and hists->entries_in (or hists->entries_collapsed). So
I guess perf report does not have leaks on hists.
But for perf top, it's possible to have half-processed entries which are
only in hists->entries_in. Eventually they will go to the
hists->entries and get freed but they cannot be deleted by current
hists__delete_entries(). This patch adds hists__delete_all_entries
function to delete those entries.

This is necessary to get rid of the browser dependency from
usage_with_options() and its friends. Because we validate the targets
which are used to create the cpu/thread maps and inform the user about
any override performed via the chosen UI, we don't need to call the
usage routine for that.

Again less intensive changes in this rc: you can find only a few
HD-audio fixes (noise fixes for Intel Broxton chip and a few Thinkpad
models, quirks for Alienware 17 and Packard Bell DOTS) in addition
to a long-standing rme96 bug fix.

The EP93xx is registering a clocksource of 40 bits with
clocksource_mmio_init() but this is not working because of this
artificial limitation. It works fine to lift the uppe limit to
64 bits, and since cycle_t is u64, it should intuitively have been
like that from the beginning.

The ACCES 104-IDIO-16 uses a single interrupt to indicate a possible
change-of-state in any of the digital input lines. As such, only a
single write to the device's "Clear Interrupt" register is necessary to
acknowledge the IRQ for all respective GPIO.
This patch moves the "Clear Interrupt" register write operation from the
irq_ack callback to the IRQ handler function, wherefore each interrupt
may be cleared respectively by executing a single outb call at the end
of the idio_16_irq_handler function, rather than multiple redundant outb
calls as a result of the generic_handle_irq call for each masked GPIO.

This patch reverts 6001d52 ("mac802154: tx: don't allow if down while
sync tx"). This has side effects with stop callback which flush the
transmit workqueue. The stop callback will wait until the workqueue is
flushed and holding the rtnl lock. That means it can happen that the stop
callback waits forever because it try to lock the rtnl mutex which is
already hold by stop callback.

If char is signed and one of these bytes happen to have a value outside
the ascii range, the corresponding output will consist of "ffffff"
followed by the two hex chars that were actually intended. One way to
fix it would be to change the casts to (u8*) aka
(unsigned char*), but it is much simpler (and generates smaller code)
to use the %ph extension which was created for such short hexdumps.

The driver is missing calls to pci_dma_mapping_error() after
performing the DMA mapping, which caused DMA-API warning to
show up in dmesg's output. Though that happens only when
DMA_API_DEBUG option is enabled. This change fixes the issue
and makes pvscsi_map_buffers() function more robust.
