+Subject: ALSA: hda: Avoid spurious unsol event handling during S3/S4
+
+From: Takashi Iwai <tiwai@suse.de>
+
+commit 5ff9dde42e8c72ed8102eb8cb62e03f9dc2103ab upstream.
+
+When HD-audio bus receives unsolicited events during its system
+suspend/resume (S3 and S4) phase, the controller driver may still try
+to process events although the codec chips are already (or yet)
+powered down. This might screw up the codec communication, resulting
+in CORB/RIRB errors. Such events should be rather skipped, as the
+codec chip status such as the jack status will be fully refreshed at
+the system resume time.
+
+Since we're tracking the system suspend/resume state in codec
+power.power_state field, let's add the check in the common unsol event
+handler entry point to filter out such events.

+Subject: ALSA: hda/hdmi: Cancel pending works before suspend
+
+From: Takashi Iwai <tiwai@suse.de>
+
+commit eea46a0879bcca23e15071f9968c0f6e6596e470 upstream.
+
+The per_pin->work might be still floating at the suspend, and this may
+hit the access to the hardware at an unexpected timing. Cancel the
+work properly at the suspend callback for avoiding the buggy access.
+
+Note that the bug doesn't trigger easily in the recent kernels since
+the work is queued only when the repoll count is set, and usually it's
+only at the resume callback, but it's still possible to hit in
+theory.

+Subject: s390/dasd: fix hanging DASD driver unbind
+
+From: Stefan Haberland <sth@linux.ibm.com>
+
+commit 7d365bd0bff3c0310c39ebaffc9a8458e036d666 upstream.
+
+In case of an unbind of the DASD device driver the function
+dasd_generic_remove() is called which shuts down the device.
+Among others this functions removes the int_handler from the cdev.
+During shutdown the device cancels all outstanding IO requests and waits
+for completion of the clear request.
+Unfortunately the clear interrupt will never be received when there is no
+interrupt handler connected.
+
+Fix by moving the int_handler removal after the call to the state machine
+where no request or interrupt is outstanding.

+Subject: scripts/recordmcount.{c,pl}: support -ffunction-sections .text.* section names
+
+From: Joe Lawrence <joe.lawrence@redhat.com>
+
+commit 9c8e2f6d3d361439cc6744a094f1c15681b55269 upstream.
+
+When building with -ffunction-sections, the compiler will place each
+function into its own ELF section, prefixed with ".text". For example,
+a simple test module with functions test_module_do_work() and
+test_module_wq_func():
+
+ % objdump --section-headers test_module.o | awk '/\.text/{print $2}'
+ .text
+ .text.test_module_do_work
+ .text.test_module_wq_func
+ .init.text
+ .exit.text
+
+Adjust the recordmcount scripts to look for ".text" as a section name
+prefix. This will ensure that those functions will be included in the
+__mcount_loc relocations:
+
+ % objdump --reloc --section __mcount_loc test_module.o
+ OFFSET TYPE VALUE
+ 0000000000000000 R_X86_64_64 .text.test_module_do_work
+ 0000000000000008 R_X86_64_64 .text.test_module_wq_func
+ 0000000000000010 R_X86_64_64 .init.text
