2013-12-03x86-64, build: Always pass in -mno-sseH. Peter Anvin
Always pass in the -mno-sse argument, regardless if -preferred-stack-boundary is supported. We never want to generate SSE instructions in the kernel unless we *really* know what we're doing. According to H. J. Lu, any version of gcc new enough that we support it at all should handle the -mno-sse option, so just add it unconditionally. Reported-by: Kevin B.

git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes From Tony Lindgren: Some omap related fixes that have come up with people moving to device tree only based booting for omap2+. The series contains a handful of fixes for the igep boards as they were one of the first omap3 boards to jump over completely to device tree based booting. So these can be considered regressions compared to booting igep in legacy mode with board files in v3.12. Also included are few other device tree vs legacy booting regressions: - yet more missing omap3 .dtsi entries that have showed up booting various boards with device tree only - n900 eMMC device tree fix - fixes for beagle USB EHCI - two fixes to make omap2420 MMC work As we're moving omap2+ to be device tree only for v3.14, I'd like to have v3.13 work equally well for legacy based booting and device tree based booting. So there will be likely few more device tree related booting patches trickling in. This series also includes a regression fix for the omap timer posted mode that may wrongly stay on from the bootloader for some SoCs. * tag 'omap-for-v3.13/fixes-against-rc1-take2' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: mmc: omap: Fix I2C dependency and make driver usable with device tree mmc: omap: Fix DMA configuration to not rely on device id ARM: dts: omap3-beagle: Fix USB host on beagle boards (for 3.13) ARM: dts: omap3-igep0020: name twl4030 VPLL2 regulator as vdds_dsi ARM: dts: AM33XX IGEP0033: add USB support ARM: dts: AM33XX BASE0033: add 32KBit EEPROM support ARM: dts: AM33XX BASE0033: add pinmux and user led support ARM: dts: AM33XX BASE0033: add pinmux and hdmi node to enable display ARM: dts: omap3-igep0020: Add pinmuxing for DVI output ARM: dts: omap3-igep0020: Add pinmux setup for i2c devices ARM: dts: omap3-igep: Update to use the TI AM/DM37x processor ARM: dts: omap3-igep: Add support for LBEE1USJYC WiFi connected to SDIO ARM: dts: omap3-igep: Fix bus-width for mmc1 ARM: OMAP2+: dss-common: change IGEP's DVI DDC i2c bus ARM: OMAP2+: Disable POSTED mode for errata i103 and i767 ARM: OMAP2+: Fix eMMC on n900 with device tree ARM: OMAP2+: Add fixed regulator to omap2plus_defconfig ARM: OMAP2+: Fix more missing data for omap3.dtsi file Signed-off-by: Olof Johansson <olof@lixom.net>

2013-12-03cpufreq: fix garbage kobjects on errors during suspend/resumeBjørn Mork
This is effectively a revert of commit 5302c3fb2e62 ("cpufreq: Perform light-weight init/teardown during suspend/resume"), which enabled suspend/resume optimizations leaving the sysfs files in place. Errors during suspend/resume are not handled properly, leaving dead sysfs attributes in case of failures. There are are number of functions with special code for the "frozen" case, and all these need to also have special error handling. The problem is easy to demonstrate by making cpufreq_driver->init() or cpufreq_driver->get() fail during resume. The code is too complex for a simple fix, with split code paths in multiple blocks within a number of functions. It is therefore best to revert the patch enabling this code until the error handling is in place. Examples of problems resulting from resume errors: WARNING: CPU: 0 PID: 6055 at fs/sysfs/file.c:343 sysfs_open_file+0x77/0x212() missing sysfs attribute operations for kobject: (null) Modules linked in: [stripped as irrelevant] CPU: 0 PID: 6055 Comm: grep Tainted: G D 3.13.0-rc2 #153 Hardware name: LENOVO 2776LEG/2776LEG, BIOS 6EET55WW (3.15 ) 12/19/2011 0000000000000009 ffff8802327ebb78 ffffffff81380b0e 0000000000000006 ffff8802327ebbc8 ffff8802327ebbb8 ffffffff81038635 0000000000000000 ffffffff811823c7 ffff88021a19e688 ffff88021a19e688 ffff8802302f9310 Call Trace: [<ffffffff81380b0e>] dump_stack+0x55/0x76 [<ffffffff81038635>] warn_slowpath_common+0x7c/0x96 [<ffffffff811823c7>] ? sysfs_open_file+0x77/0x212 [<ffffffff810386e3>] warn_slowpath_fmt+0x41/0x43 [<ffffffff81182dec>] ? sysfs_get_active+0x6b/0x82 [<ffffffff81182382>] ? sysfs_open_file+0x32/0x212 [<ffffffff811823c7>] sysfs_open_file+0x77/0x212 [<ffffffff81182350>] ? sysfs_schedule_callback+0x1ac/0x1ac [<ffffffff81122562>] do_dentry_open+0x17c/0x257 [<ffffffff8112267e>] finish_open+0x41/0x4f [<ffffffff81130225>] do_last+0x80c/0x9ba [<ffffffff8112dbbd>] ? inode_permission+0x40/0x42 [<ffffffff81130606>] path_openat+0x233/0x4a1 [<ffffffff81130b7e>] do_filp_open+0x35/0x85 [<ffffffff8113b787>] ? __alloc_fd+0x172/0x184 [<ffffffff811232ea>] do_sys_open+0x6b/0xfa [<ffffffff811233a7>] SyS_openat+0xf/0x11 [<ffffffff8138c812>] system_call_fastpath+0x16/0x1b The failure to restore cpufreq devices on cancelled hibernation is not a new bug. It is caused by the ACPI _PPC call failing unless the hibernate is completed. This makes the acpi_cpufreq driver fail its init. Previously, the cpufreq device could be restored by offlining the cpu temporarily. And as a complete hibernation cycle would do this, it would be automatically restored most of the time. But after commit 5302c3fb2e62 the leftover sysfs attributes will block any device add action. Therefore offlining and onlining CPU 1 will no longer restore the cpufreq object, and a complete suspend/resume cycle will replace it with garbage.

2013-12-03gpiolib: change a warning to debug message when failing to get gpioHeikki Krogerus
It's the drivers responsibility to react on failure to get the gpio descriptors and not the frameworks. Since there are some common peripherals that may or may not have certain pins connected to gpio lines, depending on the platform, printing the warning there may end up generating useless bug reports.

2013-12-03powerpc/gpio: Fix the wrong GPIO input data on MPC8572/MPC8536Liu Gang
For MPC8572/MPC8536, the status of GPIOs defined as output cannot be determined by reading GPDAT register, so the code use shadow data register instead. But the code may give the wrong status of GPIOs defined as input under some scenarios: 1. If some pins were configured as inputs and were asserted high before booting the kernel, the shadow data has been initialized with those pin values. 2. Some pins have been configured as output first and have been set to the high value, then reconfigured as input. The above cases will make the shadow data for those input pins to be set to high. Then reading the pin status will always return high even if the actual pin status is low. The code should eliminate the effects of the shadow data to the input pins, and the status of those pins should be read directly from GPDAT.

2013-12-03gpiolib: use platform GPIO mappings as fallbackAlexandre Courbot
For platforms that use device tree or ACPI as the standard way to look GPIOs up, allow the platform-defined GPIO mappings to be used as a fallback. This may be useful for platforms that need extra GPIOs mappings not defined by the firmware.

2013-12-03ALSA: hda - Fix headset mic input after muted internal mic (Dell/Realtek)David Henningsson
By trial and error, I found this patch could work around an issue where the headset mic would stop working if you switch between the internal mic and the headset mic, and the internal mic was muted. It still takes a second or two before the headset mic actually starts working, but still better than nothing. Information update from Kailang: The verb was ADC digital mute(bit 6 default 1). Switch internal mic and headset mic will run alc_headset_mode_default. The coef index 0x11 will set to 0x0041. Because headset mode was fixed type. It doesn't need to run alc_determine_headset_type. So, the value still keep 0x0041. ADC was muted.
