Commit 6bfff31e77 (libata: kill probe_ent
and related helpers) killed ata_device_add() but didn't remove references
to it from the libata developer's guide.
Commits 9363c3825e (libata: rename SFF
functions) and 5682ed33aa (libata: rename
SFF port ops) renamed the taskfile access methods but didn't update the
developer's guide. Commit c9f75b04ed
(libata: kill ata_noop_dev_select()) didn't update the developer's
guide as well.
The guide also refers to the long gone ata_pio_data_xfer_noirq(),
ata_pio_data_xfer(), and ata_mmio_data_xfer() -- replace those by
the modern ata_sff_data_xfer_noirq(), ata_sff_data_xfer(), and
ata_sff_data_xfer32().
Also, remove the reference to non-existant ata_port_stop()...

Fix a couple of inefficiencies and redundancies related to
have_tracepoints() and its use when checking whether to write
TRACE_INFO.
First, there's no need to use get_tracepoints_path() in
have_tracepoints() - we really just want the part that checks whether
any attributes correspondo to tracepoints.
Second, we really don't care about raw_samples per se - tracepoints
are always raw_samples. In any case, the have_tracepoints() check
should be sufficient to decide whether or not to write TRACE_INFO.

call_sbin_request_key() creates a keyring and then attempts to insert a link to
the authorisation key into that keyring, but does so without holding a write
lock on the keyring semaphore.
It will normally get away with this because it hasn't told anyone that the
keyring exists yet. The new keyring, however, has had its serial number
published, which means it can be accessed directly by that handle.
This was found by a previous patch that adds RCU lockdep checks to the code
that reads the keyring payload pointer, which includes a check that the keyring
semaphore is actually locked.
Without this patch, the following command:
keyctl request2 user b a @s
will provoke the following lockdep warning is displayed in dmesg:

We should disable irqs when we take the tu->qlock because it is used in

KEYS: Fix RCU handling in key_gc_keyring()
KEYS: Fix an RCU warning in the reading of user keys
key_gc_keyring() needs to either hold the RCU read lock or hold the keyring
semaphore if it's going to scan the keyring's list. Given that it only needs
to read the key list, and it's doing so under a spinlock, the RCU read lock is
the thing to use.
Furthermore, the RCU check added in e7b0a61b79 is
incorrect as holding the spinlock on key_serial_lock is not grounds for
assuming a keyring's pointer list can be read safely. Instead, a simple
rcu_dereference() inside of the previously mentioned RCU read lock is what we
want.

On a large machine we spend a lot of time in perf_header__find_attr when
running perf report.
If we are parsing a file without PERF_SAMPLE_ID then for each sample we call
perf_header__find_attr and loop through all counter IDs, never finding a match.
As the machine gets larger there are more per cpu counters and we spend an
awful lot of time in there.
The patch below initialises each sample id to -1ULL and checks for this in
perf_header__find_attr. We may need to do something more intelligent eventually
(eg a hash lookup from counter id to attr) but this at least fixes the most
common usage of perf report.

Some FSC hardware monitoring chips (Syleus at least) doesn't like
quick writes we typically use to probe for I2C chips. Use a regular
byte read instead for the address they live at (0x73). These are the
only known chips living at this address on PC systems.
For clarity, this fix should not be needed for kernels 2.6.30 and
later, as we started instantiating the hwmon devices explicitly based
on DMI data. Still, this fix is valuable in the following two cases:
* Support for recent FSC chips on older kernels. The DMI-based device
instantiation is more difficult to backport than the device support
itself.
* Case where the DMI-based device instantiation fails, whatever the
reason. We fall back to probing in that case, so it should work.

Receiving small packet(s) in a fast pace leads to not receiving any
packets at all after some time.
After ethernet packet(s) arrived the receive descriptor is incremented
by the number of frames processed. If another packet arrives while
processing, this is processed in another call of ep93xx_rx. This
second call leads that too many receive descriptors getting released.
This fix increments, even in these case, the right number of processed
