Builds started failing in Fedora on Python 3.7 with:
`.gnu.debuglto_.debug_macro' referenced in section
`.gnu.debuglto_.debug_macro' of
util/scripting-engines/trace-event-python.o: defined in discarded
section
In Fedora, Python 3.7 added -flto to the list of --cflags and since it
was only applied to util/scripting-engines/trace-event-python.c and
scripts/python/Perf-Trace-Util/Context.c, linking failed.
It's not the first time the addition of flags has broken builds: commit
c6707fdef7 ("perf tools: Fix up build in hardnened environments")
appears to have fixed a similar problem. "python-config --includes"
provides the proper -I flags and doesn't introduce additional CFLAGS.

The dictionaries are attached to the parameter tuple that steals the
references and takes care of releasing them when appropriate. The code
should not decrement the reference counts explicitly. E.g. if libpython
has been built with reference debugging enabled, the superfluous DECREFs
will trigger this error when running perf script:
Fatal Python error: Objects/tupleobject.c:238 object at
0x7f10f2041b40 has negative ref count -1
Aborted (core dumped)
If the reference debugging is not enabled, the superfluous DECREFs might
cause the dict objects to be silently released while they are still in
use. This may trigger various other assertions or just cause perf
crashes and/or weird and unexpected data changes in the stored Python
objects.

get_seconds() is deprecated because it can overflow on 32-bit
architectures. For the xfrm_state->lastused member, we treat the data

The lifetime managment uses '__u64' timestamps on the user space
interface, but 'unsigned long' for reading the current time in the kernel
with get_seconds().
While this is probably safe beyond y2038, it will still overflow in 2106,
and the get_seconds() call is deprecated because fo that.
This changes the xfrm time handling to use time64_t consistently, along
with reading the time using the safer ktime_get_real_seconds(). It still
suffers from problems that can happen from a concurrent settimeofday()
call or (to a lesser degree) a leap second update, but since the time
stamps are part of the user API, there is nothing we can do to prevent
that.

getrawmonotonic64() and get_monotonic_boottime64() are deprecated
because of the nonstandard naming.
The replacement functions ktime_get_raw_ns() and ktime_get_boot_ns()
also simplify the callers.

As documented in GCC naked functions should only use basic ASM
syntax. The extended ASM or mixture of basic ASM and "C" code is
not guaranteed. Currently this works because it was hard coded
to follow and check GCC behavior for arguments and register
placement.
Furthermore with clang using parameters in Extended asm in a
naked function is not supported:
arch/arm/firmware/trusted_foundations.c:47:10: error: parameter
references not allowed in naked functions
: "r" (type), "r" (arg1), "r" (arg2)
^
Use a regular function to be more portable. This aligns also with
the other SMC call implementations e.g. in qcom_scm-32.c and
bcm_kona_smc.c.
