Do not cache pointers into the skb linear segment across sk_filter.

In kernel HTB keeps tokens in signed 64-bit in nanoseconds. In netlink
protocol these values are converted into pshed ticks (64ns for now) and
truncated to 32-bit. In struct tc_htb_xstats fields "tokens" and "ctokens"
are declared as unsigned 32-bit but they could be negative thus tool 'tc'
prints them as signed. Big values loose higher bits and/or become negative.
This patch clamps tokens in xstat into range from INT_MIN to INT_MAX.
In this way it's easier to understand what's going on here.

The props->ap[] array is defined like this:
struct alg_props ap[NX_MAX_FC][NX_MAX_MODE][3];
So we can see that if msc->fc and msc->mode are == to NX_MAX_FC or
NX_MAX_MODE then we're off by one.

Since commit 1bdf02326b71e ("clk: at91: make use of syscon/regmap

Jirka reported that python code returns all arrays as strings. This

Warn unmatched function filter correctly instead of warning
"symbol-loading error", since that can be a filter issue.
From the technical point of view, this adds a filter chech in map__load
and if there is a filter, it returns -2 (filter-out), instead of -1
(error), and perf-probe checks it and change message.
E.g. without this fix:
# perf probe -F rt_sp*
no symbols found in [kernel.kallsyms], maybe install a debug package?
Failed to load symbols in kernel
With this fix:
# perf probe -F rt_sp*
no symbols passed the given filter.
Failed to find symbols matched to "rt_sp*"
Error: Failed to show functions.

In some cases it's necessry to figure out the map-local index of a given
Linux logical CPU ID. Add a new helper, cpu_map__idx, to acquire this.
As the logic is largely the same as the existing cpu_map__has, this is
rewritten in terms of the new helper.
At the same time, add the inverse operation, cpu_map__cpu, which yields
the logical CPU id for a map-local index. While this can be performed
manually, wrapping this in a helper can make code more legible.

In create_perf_stat_counter, when a target CPU has not been provided, we
call __perf_evsel__open with empty_cpu_map, and open a single FD per
thread. However, in read_counter we assume that we opened events for the
product of threads and CPUs described in the evsel's cpu_map.
Thus, if an evsel has a cpu_map with more than one entry, we will
attempt to access FDs that we didn't open. This could result in a number
of problems (e.g. blocking while reading from STDIN if the fd memory
happened to be initialised to zero).
This is problematic for systems were a logical CPU PMU covers some
arbitrary subset of CPUs. The cpu_map of any evsel for that PMU will be
initialised based on the cpumask exposed through sysfs, even if the user
requests per-thread events.

in some drives that commands with "count" set to 0000h (which
reprsents 65536) does not work as expected, lba_48_ok(), which is
used for number-of-blocks checking when libata pack commands, should
use the same limit as well. In fact, there is no reason for the two
functions not to use the macros anyway.

As reported by Dan in his report in [1], there is a potential NULL
pointer derefence if these conditions are met :
- there is no platform_data provided, ie. host->pdata = NULL
Fix this by only using the platform data ro_invert when a gpio for
read-only is provided by the platform data.
This doesn't appear yet as every pxa board provides a platform_data, and
calls pxa_set_mci_info() with a non NULL pointer.

When there is more data to be processed, the current test in
scatterwalk_done may prevent us from calling pagedone even when
we should.
In particular, if we're on an SG entry spanning multiple pages
where the last page is not a full page, we will incorrectly skip
calling pagedone on the second last page.
This patch fixes this by adding a separate test for whether we've
reached the end of a page.

This patch removes the old crypto_grab_skcipher helper and replaces
it with crypto_grab_skcipher2.
As this is the final entry point into givcipher this patch also
removes all traces of the top-level givcipher interface, including
all implicit IV generators such as chainiv.
The bottom-level givcipher interface remains until the drivers
using it are converted.

As there are no more kernel users of built-in IV generators we
can remove the special lookup for skciphers.

This patch converts cts over to the skcipher interface. It also
optimises the implementation to use one CBC operation for all but
the last block, which is then processed separately.
