Reinette Chatre 89c581b3fb iwlwifi: fix suspend/resume and its usage of pci saved state
Here we do two things:

First, revert "iwlwifi: save PCI state before suspend, restore after
resume".  That misguided patch led to being unable to use iwlwifi
devices after resume.

Next, indicate to PCI driver that the saved PCI state is valid during suspend.

We restore PCI state and enable the device when network interface is created,
similarly PCI state is saved and the device is disabled when network interface
is removed. Thus, when .suspend is called the PCI state is saved and device
is disabled. This is the case even if an interface is never created as PCI
state is saved and device disabled during .probe.

PCI driver assumes PCI state is saved in .suspend. Saving the state at this
time will save state of disabled device and thus cause problems during
resume (resuming a disabled device). We thus indicate directly to PCI
driver that current PCI saved state is valid.

Stefan Weinhuber 48cae885d5 [S390] dasd: fix race in dasd timer handling
In dasd_device_set_timer and dasd_block_set_timer we interpret the
return value of mod_timer in a wrong way. If the timer expires in
the small window between our check of timer_pending and the call to
mod_timer, then the timer will be set, mod_timer returns zero and
we will call add_timer for a timer that is already pending.
As del_timer and mod_timer do all the necessary checking themselves,
we can simplify our code and remove the race a the same time.

Oleg Nesterov 06eb23b1ba ptrace, x86: fix the usage of ptrace_fork()
I noticed by pure accident we have ptrace_fork() and friends. This was
added by "x86, bts: add fork and exit handling", commit
bf53de907d.

I can't test this, ds_request_bts() returns -EOPNOTSUPP, but I strongly
believe this needs the fix. I think something like this program

	int main(void)
	{
		int pid = fork();

		if (!pid) {
			ptrace(PTRACE_TRACEME, 0, NULL, NULL);
			kill(getpid(), SIGSTOP);
			fork();
		} else {
			struct ptrace_bts_config bts = {
				.flags = PTRACE_BTS_O_ALLOC,
				.size  = 4 * 4096,
			};

			wait(NULL);

			ptrace(PTRACE_SETOPTIONS, pid, NULL, PTRACE_O_TRACEFORK);
			ptrace(PTRACE_BTS_CONFIG, pid, &bts, sizeof(bts));
			ptrace(PTRACE_CONT, pid, NULL, NULL);

			sleep(1);
		}

		return 0;
	}

should crash the kernel.

If the task is traced by its natural parent ptrace_reparented() returns 0
but we should clear ->btsxxx anyway.

Wu Fengguang 606c0cee69 ALSA: hda - enable HDMI audio pin out at module loading time
We found that enabling/disabling HDMI audio pin out at stream start/stop
time will kill the leading 500ms or so sound samples. Avoid this by enabling
pin out once and for ever at module loading time.

The leading ~500ms audio samples will still be lost when switching from
X-channel playback to Y-channel playback where X != Y. However there's no
much we can do about it: the audio infoframe has to change and it looks like
either G45 or YAMAHA requires some time to switch the configuration.

The YAMAHA AV-X1800 requires audio infoframe to include speaker-channel
mapping to play >2 channel HDMI audio. In theory that mapping should be
derived from its speaker configurations contained in its ELD. However we
currently cannot get ELD in console before the KMS functionalities are ready.
This is a more or less general issue at least in the near future. As a
workaround, we propose to allow playback of mult-channel audio when ELD
is not available.

Meelis Roos 7b7a799d66 sunhme: Fix Quattro HME irq registration on proble failures
Currently, the sunhme driver installs SBus Quattro interrupt handler 
when at least one HME card was initialized correctly and at least one 
Quattro card is present. This breaks when a Quattro card fails 
initialization for whatever reason - IRQ is registered and OOPS happens 
when it fires.

The solution, as suggested by David Miller, was to keep track which 
cards of the Quattro bundles have been initialized, and request/free the 
Quattro IRQ only when all four devices have been successfully 
initialized.

The patch only touches SBus initialization - PCI init already resets the 
card pointer to NULL on init failure.

The patch has been tested on Sun E3500 with SBus and PCI single HME 
cards and one PCI Quattro HME card in a situation where any PCI card 
failed init when the SBus routines tried to init them by mistake.

Additionally it replaces Quattro request_irq panic with error return - 
if this card fails to work, at least let the others work.

Tested on E450 with PCI HME and PCI Quad HME.

dave graham c9523379d6 e1000e: Serdes - attempt autoneg when link restored.
This patch addresses an issue where we did not restart auto-negotiation on
serdes links when the link partner was disabled and re-enabled. It includes
reworking the serdes link detect mechanism to be a state machine for
82571 and 82572 parts only.

dave graham 573cca8c6f e1000e: remove RXSEQ link monitoring for serdes
RXSEQ interrupts were used to force link state interrogation of serdes
links, as the Si was not guaranteed to report LSC interrupts when the
link changed state. On some bladeservers this resulted in false link up
reports if no link partner was connected. The RXSEQ treatment is
not necessary, as the link can be monitored from the watchdog timer, and
the false link indications cease.

dave graham 5df3f0eaf8 e1000e: Disable dynamic clock gating for 82571 per si errata.
82571 and 82572 Errata #13 documents that the Si feature DMA Dynamic
Clock Gating should be disabled, and identifies the workaround of
disabling the feature by EEPROM setting. EEPROM versions that do not
include the recommended workaround have been found in the field, and so
some customers remain at risk. Because the feature DMA Dynamic clock
Gating can be disabled by directly setting the appropriate bit in the
E1000_CTRL_EXT register, this patch overrides the EEPROM setting, and
force-disables the feature.
