2012-02-20ALSA: hda/realtek - Rewrite ALC880 model=z71v with auto-parserTakashi Iwai
ASUS Z71V has a totally broken BIOS setup (at least the info I got), thus we need to override the whole pin-config table to make the auto-parser working correctly. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2012-02-20ALSA: hda/realtek - Rewrite ALC880 model=uniwill with auto-parserTakashi Iwai
The model=uniwill would work almost as is, but a couple of adjustments are needed to make the mutli-io working correctly. The headphone and speaker pins have to be marked properly in pin configs. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2012-02-20ALSA: hda/realtek - Rewrite ALC880 model=F1734 with auto-parserTakashi Iwai
Similar as the previous patch for model=fujitsu, we can now move the static quirk for F1734 to the auto-parser. The only difference is the default pin configurations: F1734 has less pins than Amilo's. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2012-02-20ALSA: hda/realtek - Rewrite ALC880 model=futjisu with auto-parserTakashi Iwai
Now adding the support for the volume-knob widget, we can move the static quirk for ALC880 model=fujitsu to the auto-parser completely. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2012-02-19[SCSI] libsas: fix domain_device leakDan Williams
Arrange for the deallocation of a struct domain_device object when it no longer has: 1/ any children 2/ references by any scsi_targets 3/ references by a lldd The comment about domain_device lifetime in Documentation/scsi/libsas.txt is stale as it appears mainline never had a version of a struct domain_device that was registered as a kobject. We now manage domain_device reference counts on behalf of external agents.

2012-02-19Wrap accesses to the fd_sets in struct fdtableDavid Howells
Wrap accesses to the fd_sets in struct fdtable (for recording open files and close-on-exec flags) so that we can move away from using fd_sets since we abuse the fd_set structs by not allocating the full-sized structure under normal circumstances and by non-core code looking at the internals of the fd_sets. The first abuse means that use of FD_ZERO() on these fd_sets is not permitted, since that cannot be told about their abnormal lengths. This introduces six wrapper functions for setting, clearing and testing close-on-exec flags and fd-is-open flags: void __set_close_on_exec(int fd, struct fdtable *fdt); void __clear_close_on_exec(int fd, struct fdtable *fdt); bool close_on_exec(int fd, const struct fdtable *fdt); void __set_open_fd(int fd, struct fdtable *fdt); void __clear_open_fd(int fd, struct fdtable *fdt); bool fd_is_open(int fd, const struct fdtable *fdt); Note that I've prepended '__' to the names of the set/clear functions because they require the caller to hold a lock to use them. Note also that I haven't added wrappers for looking behind the scenes at the the array. Possibly that should exist too.

2012-02-17ALSA: hda/realtek - Replace ALC880 model=tcl with auto-parserTakashi Iwai
It needs a few extra setups for EAPD, but others look fairly straightforward. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2012-02-17ALSA: hda/realtek - Drop ALC880 model=clevoTakashi Iwai
Clevo machines with ALC880 are all well with proper BIOS setup. It seems still requiring the additional COEF setup for the EAPD. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2012-02-17ALSA: hda/realtek - Rewrite ALC880 model=w810 with auto-parserTakashi Iwai
The Medion W810 with ALC880 has a typical BIOS bug, copying the pin-defaults without disabling the unused pins. At least, the pin 0x17 must be disabled. Also, it requires GPIO-2 setup. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2012-02-17ALSA: hda/realtek - Rewrite ALC880 model=lg with the auto-parserTakashi Iwai
ALC880 model=lg could work fine with the auto-parser due to the recent rewrite, but it still needs the manual adjustment; namely, the BIOS leaves unused pins as some real active jacks. This confuses the parser. Thus we just cover these pins and override the pin-configs as a fix-up. Signed-off-by: Takashi Iwai <tiwai@suse.de>

2012-02-16ALSA: hda/realtek - Remove leftover static quirks for ALC260Takashi Iwai
Now we can clean up all static quirks for ALC260. Also many codes in alc_quirks.c can be ripped off since they have been used only by ALC260 static quirks. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2012-02-16ALSA: hda/realtek - Drop model=fujitsu from ALC260 static quirksTakashi Iwai

2012-02-16ALSA: hda/realtek - Drop model=favorit100 for ALC260Takashi Iwai

2012-02-16ALSA: hda/realtek - Replace ALC260 model=replacer with the auto-parserTakashi Iwai
The support for Replacer 627V in the auto-parser needs the unique unsol event handling: although the machine has a single output pin 0x0f, it's used for both the headphone and the speaker, and the driver needs to toggle the output route via GPIO 1. In addition, it needs a special COEF setup with 0x3050. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2012-02-16ALSA: hda/realtek - Replace ALC260 model=acer with the auto-parserTakashi Iwai
The ALC260 model=acer needs GPIO1 setup. It could be selected well if the codec SSID is set properly by BIOS, but to make sure, enable it forcibly. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2012-02-16ALSA: hda/realtek - Add the fixup codes for ALC260 model=willTakashi Iwai
The model=will for ALC260 requires the pin 0x0f to be a headphone and some special verbs for the COEF to turn on the amp. Now added these as fixup entries and removed the static model quirk. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2012-02-16Yama: add PR_SET_PTRACER_ANYKees Cook
For a process to entirely disable Yama ptrace restrictions, it can use the special PR_SET_PTRACER_ANY pid to indicate that any otherwise allowed process may ptrace it. This is stronger than calling PR_SET_PTRACER with pid "1" because it includes processes in external pid namespaces. This is currently needed by the Chrome renderer, since its crash handler (Breakpad) runs external to the renderer's pid namespace.

2012-02-10pinctrl: changes hog mechanism to be self-referentialLinus Walleij

2012-02-10pinctrl: move generic functions to the pinctrl_ namespaceLinus Walleij
Since we want to use the former pinmux handles and mapping tables for generic control involving both muxing and configuration we begin refactoring by renaming them from pinmux_* to pinctrl_*.

2012-02-09PM / Freezer / Docs: Document the beauty of freeze/thaw semanticsSrivatsa S. Bhat
The way the different freeze/thaw functions encapsulate each other are quite lovely from a design point of view. And as a side-effect, the way in which they are invoked (cleaning up on failure for example) differs significantly from how usual functions are dealt with. This is because of the underlying semantics that govern the freezing and thawing of various tasks. This subtle aspect that differentiates these functions from the rest, is worth documenting.

2012-02-08rpmsg: add virtio-based remote processor messaging busOhad Ben-Cohen
Add a virtio-based inter-processor communication bus, which enables kernel drivers to communicate with entities, running on remote processors, over shared memory using a simple messaging protocol. Every pair of AMP processors share two vrings, which are used to send and receive the messages over shared memory. The header of every message sent on the rpmsg bus contains src and dst addresses, which make it possible to multiplex several rpmsg channels on the same vring. Every rpmsg channel is a device on this bus. When a channel is added, and an appropriate rpmsg driver is found and probed, it is also assigned a local rpmsg address, which is then bound to the driver's callback. When inbound messages carry the local address of a bound driver, its callback is invoked by the bus. This patch provides a kernel interface only; user space interfaces will be later exposed by kernel users of this rpmsg bus. Designed with Brian Swetland <swetland@google.com>.

2012-02-08remoteproc: add framework for controlling remote processorsOhad Ben-Cohen
Modern SoCs typically employ a central symmetric multiprocessing (SMP) application processor running Linux, with several other asymmetric multiprocessing (AMP) heterogeneous processors running different instances of operating system, whether Linux or any other flavor of real-time OS. Booting a remote processor in an AMP configuration typically involves: - Loading a firmware which contains the OS image - Allocating and providing it required system resources (e.g. memory) - Programming an IOMMU (when relevant) - Powering on the device This patch introduces a generic framework that allows drivers to do that. In the future, this framework will also include runtime power management and error recovery. Based on (but now quite far from) work done by Fernando Guzman Lugo <fernando.lugo@ti.com>.
