git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-next Summary: - change exynos file license . Most of exynos files had been copied from some randome file and not updated correctly(wrong company name used). This was our mistakes so chagnes it correctly. For this, I'm not sure that this patch should go to -fix or -next. So please give me any comment if there is any problem. - consider buffer allocation without iommu . Without iommu, dma_alloc_attrs function allocates some memory region and returns cpu address so this patch makes the cpu address to be set to buf->kvaddr correctly - cleanups to ipp relevant codes. - use common finish page flip function . to avoid the duplication of same code, use exynos_drm_crtc_finish_pageflip function commonly instead of each one. - fix fimd resume issue. . when fimd was turned off by suspend, there was one issue that the fimd wasn't turned on by resume so fix it chaing resume condition. * 'exynos-drm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos: (25 commits) drm/exynos: move finish page flip to a common place drm/exynos: fimd: modify condition in fimd resume drm/exynos: Use devm_clk_get in exynos_drm_gsc.c drm/exynos: Remove redundant NULL check in exynos_drm_gsc.c drm/exynos: Remove explicit freeing using devm_* APIs in exynos_drm_gsc.c drm/exynos: Use devm_clk_get in exynos_drm_rotator.c drm/exynos: Remove redundant NULL check in exynos_drm_rotator.c drm/exynos: Remove unnecessary devm_* freeing APIs in exynos_drm_rotator.c drm/exynos: Use devm_clk_get in exynos_drm_fimc.c drm/exynos: Remove redundant NULL check drm/exynos: Remove explicit freeing using devm_* APIs in exynos_drm_fimc.c drm/exynos: Use devm_kzalloc in exynos_drm_ipp.c drm/exynos: fix gem buffer allocation type checking drm/exynos: remove needless parenthesis. drm/exynos: fix incorrect interrupt induced by m2m operation. drm/exynos: remove color bar pattern operation. drm/exynos: correct some comments to abbreviation. drm/exynos: fix build warning. drm/exynos: consider both case of vflip and hflip. drm/exynos: remove needless error handling to property. ...

2013-01-07sctp: fix Kconfig bug in default cookie hmac selectionAlex Elder
Commit 0d0863b02002 ("sctp: Change defaults on cookie hmac selection") added a "choice" to the sctp Kconfig file. It introduced a bug which led to an infinite loop when while running "make oldconfig". The problem is that the wrong symbol was defined as the default value for the choice. Using the correct value gets rid of the infinite loop. Note: if CONFIG_SCTP_COOKIE_HMAC_SHA1=y was present in the input config file, both that and CONFIG_SCTP_COOKIE_HMAC_MD5=y be present in the generated config file.

After f65aad41772f("MIPS: Cavium: Add EDAC support."), when entering the "Device Drivers" toplevel menu in menuconfig, the suboptions behind EDAC appeared merged with the rest of the device drivers types. This was because the menuconfig option EDAC is querying an EDAC_SUPPORT Kconfig bool which was defined after the menu definition. When pushing EDAC_SUPPORT up, before the menu definition, the variable is defined earlier and the above menuconfig artifact doesn't happen. Drop a useless menuconfig comment while at it.

vga-switcheroo with apple-gmux does not switch correctly on my system. The PCI configuration space is not restored correctly, resulting in MSI not working after switch. Only useful item in dmesg is: [ 33.922807] radeon 0000:01:00.0: Refused to change power state, currently in D3 I did some testing, dumping the difference in ms between first succesful switch from D3 to D0, and it seems that there is slightly more than 20 ms difference when the device is re-enabled through vga-switcheroo. So bump the re-enable d3 delay to 20 ms to handle this, which fixes msi not working on my system after switcheroo-ing. Default d3_delay value is PCI_PM_D3_WAIT, 10 ms.

2013-01-06tcp: fix MSG_SENDPAGE_NOTLAST logicEric Dumazet
commit 35f9c09fe9c72e (tcp: tcp_sendpages() should call tcp_push() once) added an internal flag : MSG_SENDPAGE_NOTLAST meant to be set on all frags but the last one for a splice() call. The condition used to set the flag in pipe_to_sendpage() relied on splice() user passing the exact number of bytes present in the pipe, or a smaller one. But some programs pass an arbitrary high value, and the test fails. The effect of this bug is a lack of tcp_push() at the end of a splice(pipe -> socket) call, and possibly very slow or erratic TCP sessions. We should both test sd->total_len and fact that another fragment is in the pipe (pipe->nrbufs > 1) Many thanks to Willy for providing very clear bug report, bisection and test programs.

Instead the existing check does the opposite. So if fimd was not runtime suspended, suspend will turn off fimd but resume will not turn it on. This patch fixes this issue by reversing the condition.

2013-01-06dma: mv_xor: fix error handling for clocksThomas Petazzoni
When a channel fails to initialize, we release all ressources, including clocks. However, a XOR unit is not necessarily associated to a clock (some variants of Marvell SoCs have a clock for XOR units, some don't), so we shouldn't unconditionally be releasing the clock. Instead, just like we do in the mv_xor_remove() function, we should check if one clock was found before releasing it.

2013-01-06dma: mv_xor: fix error handling of mv_xor_channel_add()Thomas Petazzoni
When mv_xor_channel_add() fails for one XOR channel, we jump to the err_channel_add label to clean up all previous channels that had been initialized correctly. Unfortunately, while handling this error condition, we were disposing the IRQ mapping before calling mv_xor_channel_remove() (which does the free_irq()), which is incorrect. Instead, do things properly in the reverse order of the initialization: first remove the XOR channel (so that free_irq() is done), and then dispose the IRQ mapping. This avoids ugly warnings when for some reason one of the XOR channel fails to initialize.

So, the definitions of the Ethernet interfaces is now done as follows: * armada-370-xp.dtsi: definitions of the first two interfaces, that are common to Armada 370 and Armada XP * armada-xp.dtsi: definition of the third interface, common to all Armada XP variants. * armada-xp-mv78260.dtsi and armada-xp-mv78460.dtsi: definition of the fourth interface.

2013-01-06arm: mvebu: Armada XP MV78230 has two cores, not oneThomas Petazzoni
Contrary to our understanding at the time armada-xp-mv78230.dtsi was written, the MV78230 variant of the Armada XP SoC has two cores and not one. This patch updates the .dtsi file to take into account this reality.

2013-01-06ARM: Kirkwood: Use fixed-regulator instead of board gpio callAndrew Lunn
With the change to a DT based pinctrl/gpio driver, using gpio API calls in board-*.c files no longer works, a dereferenced NULL pointer exception occurs instead. By converting the GPIO code into a fixed-regulator which gets probed later once pinctrl/gpio is available, we avoid the exception.

2013-01-06arm: mvebu: Use dw-apb-uart instead of ns16650 as UART driverGregory CLEMENT
The UART controller used in the Armada 370 and Armada XP SoCs is the Synopsys DesignWare 8250 (aka Synopsys DesignWare ABP UART). The improper use of the ns16550 can lead to a kernel oops during boot if a character is sent to the UART before the initialization of the driver. The DW APB has an extra interrupt that gets raised when writing to the LCR when busy. This explains why we need to use dw-apb-uart driver to handle this.

Cleanup. And I think we need more cleanups, in particular __set_current_blocked() and sigprocmask() should die. Nobody should ever block SIGKILL or SIGSTOP. - Change set_current_blocked() to use __set_current_blocked() - Change sys_sigprocmask() to use set_current_blocked(), this way it should not worry about SIGKILL/SIGSTOP.

* pm-sleep: PM: Move disabling/enabling runtime PM to late suspend/early resume
2013-01-06PM: Move disabling/enabling runtime PM to late suspend/early resumeRafael J. Wysocki
Currently, the PM core disables runtime PM for all devices right after executing subsystem/driver .suspend() callbacks for them and re-enables it right before executing subsystem/driver .resume() callbacks for them. This may lead to problems when there are two devices such that the .suspend() callback executed for one of them depends on runtime PM working for the other. In that case, if runtime PM has already been disabled for the second device, the first one's .suspend() won't work correctly (and analogously for resume). To make those issues go away, make the PM core disable runtime PM for devices right before executing subsystem/driver .suspend_late() callbacks for them and enable runtime PM for them right after executing subsystem/driver .resume_early() callbacks for them. This way the potential conflitcs between .suspend_late()/.resume_early() and their runtime PM counterparts are still prevented from happening, but the subtle ordering issues related to disabling/enabling runtime PM for devices during system suspend/resume are much easier to avoid.
