+Subject: ALSA: hda - Adjust speaker HPF and add LED support for HP Spectre 13
+
+From: Takashi Iwai <tiwai@suse.de>
+
+commit 8b3dfdaf0c25a584cb31d04d2574115cf2d422ab upstream.
+
+HP Spectre 13 has the IDT 92HD95 codec, and BIOS seems to set the
+default high-pass filter in some "safer" range, which results in the
+very soft tone from the built-in speakers in contrast to Windows.
+Also, the mute LED control is missing, since 92HD95 codec still has no
+HP-specific fixups for GPIO setups.
+
+This patch adds these missing features: the HPF is adjusted by the
+vendor-specific verb, and the LED is set up from a DMI string (but
+with the default polarity = 0 assumption due to the incomplete BIOS on
+the given machine).

+
+syscall_regfunc() and syscall_unregfunc() should set/clear

+Change copy_process() to update the child's TIF_SYSCALL_TRACEPOINT

+Subject: tracing: Try again for saved cmdline if failed due to locking
+
+From: "Steven Rostedt (Red Hat)" <rostedt@goodmis.org>
+
+commit 379cfdac37923653c9d4242d10052378b7563005 upstream.
+
+In order to prevent the saved cmdline cache from being filled when
+tracing is not active, the comms are only recorded after a trace event
+is recorded.
+
+The problem is, a comm can fail to be recorded if the trace_cmdline_lock
+is held. That lock is taken via a trylock to allow it to happen from
+any context (including NMI). If the lock fails to be taken, the comm
+is skipped. No big deal, as we will try again later.
+
+But! Because of the code that was added to only record after an event,
+we may not try again later as the recording is made as a oneshot per
+event per CPU.
+
+Only disable the recording of the comm if the comm is actually recorded.
+
