2012-02-13mmc: core: Fix PowerOff Notify suspend/resumeGirish K S3-12/+35
Modified the mmc_poweroff to resume before sending the poweroff notification command. In sleep mode only AWAKE and RESET commands are allowed, so before sending the poweroff notification command resume from sleep mode and then send the notification command. PowerOff Notify is tested on a Synopsis Designware Host Controller (eMMC 4.5). The suspend to RAM and resume works fine.

2012-02-13mmc: core: add the capability for broken voltageJaehoon Chung2-0/+5
There is an understood mismatch between the voltage the host controller is set to and the voltage supplied to the card by a fixed voltage regulator. Teaching the driver to accept the mismatch is overly complicated. Instead just accept the regulator's voltage. This patch adds MMC_CAP2_BROKEN_VOLTAGE. If the voltage didn't satisfy between min_uV and max_uV, try to change the voltage in core.c. When changing the voltage, maybe use regulator_set_voltage(). In regulator_set_voltage(), check the below condition. /* sanity check */ if (!rdev->desc->ops->set_voltage && !rdev->desc->ops->set_voltage_sel) { ret = -EINVAL; goto out; } If some board should use the fixed-regulator, always return -EINVAL. Then, eMMC didn't initialize always. So if use a fixed-regulator, we need to add the MMC_CAP2_BROKEN_VOLTAGE.

This set of changes are fixing various section mismatch warnings which look to be completely valid. Primerily, those which are fixed are those which can cause oopses by manipulation of driver binding via sysfs. For example: calling code marked __init from driver probe __devinit functions. Some of these changes will be reworked at the next merge window when the underlying reasons are sorted out. In the mean time, I think it's important to have this fixed for correctness. Also included in this set are fixes to various error messages in OMAP - including making them gramatically correct, fixing a few spelling errors, and more importantly, making them greppable by unwrapping them. Tony Lindgren has acked all these patches, put them out for testing a week ago, and I've tested them on the platforms I have. * 'omap-fixes-warnings' of git://git.linaro.org/people/rmk/linux-arm: ARM: omap: resolve nebulous 'Error setting wl12xx data' ARM: omap: fix wrapped error messages in omap_hwmod.c ARM: omap: fix section mismatch warnings in mux.c caused by hsmmc.c ARM: omap: fix section mismatch warning for sdp3430_twl_gpio_setup() ARM: omap: fix section mismatch error for omap_4430sdp_display_init() ARM: omap: fix section mismatch warning for omap_secondary_startup() ARM: omap: preemptively fix section mismatch in omap4_sdp4430_wifi_mux_init() ARM: omap: fix section mismatch warning in mux.c ARM: omap: fix section mismatch errors in TWL PMIC driver ARM: omap: fix uninformative vc/i2c configuration error message ARM: omap: fix vc.c PMIC error message ARM: omap: fix prm44xx.c OMAP44XX_IRQ_PRCM build error

2012-02-13i387: make irq_fpu_usable() tests more robustLinus Torvalds2-8/+47
Some code - especially the crypto layer - wants to use the x86 FP/MMX/AVX register set in what may be interrupt (typically softirq) context. That *can* be ok, but the tests for when it was ok were somewhat suspect. We cannot touch the thread-specific status bits either, so we'd better check that we're not going to try to save FP state or anything like that. Now, it may be that the TS bit is always cleared *before* we set the USEDFPU bit (and only set when we had already cleared the USEDFP before), so the TS bit test may actually have been sufficient, but it certainly was not obviously so. So this explicitly verifies that we will not touch the TS_USEDFPU bit, and adds a few related sanity-checks. Because it seems that somehow AES-NI is corrupting user FP state. The cause is not clear, and this patch doesn't fix it, but while debugging it I really wanted the code to be more obviously correct and robust.

2012-02-13ALSA: hda - Fix silent speaker output on Acer Aspire 6935Takashi Iwai1-0/+23
Since 3.2 kernel, the driver starts trying to assign the multi-io DACs before the speaker, thus it assigns DAC2/3 for multi-io and DAC4 for the speaker for a standard laptop setup like a HP, a speaker, a mic-in and a line-in. However, on Acer Aspire 6935, it seems that the speaker pin 0x14 must be connected with either DAC1 or 2; otherwise it results in silence by some reason, although the codec itself allows the routing to DAC3/4. As a workaround, the connection list of each pin is reduced to be mapped to either only DAC1/2 or DAC3/4, so that the compatible assignment as in kernel 3.1 is achieved.

2012-02-13ALSA: hda - Fix initialization of secondary capture source on VT1705Takashi Iwai1-0/+3
VT1705 codec has two ADCs where the secondary ADC has no MUX but only a fixed connection to the mic pin. This confused the driver and it tries always overriding the input-source selection by assumption of the existing MUX for the secondary ADC, resulted in resetting the input-source at each time PM (including power-saving) occurs. The fix is simply to check the existence of MUX for secondary ADCs in the initialization code.

2012-02-13ARM: omap: resolve nebulous 'Error setting wl12xx data'Russell King4-15/+33
It's useful to print the error code when a called function fails so a diagnosis of why it failed is possible. In this case, it fails because we try to register some data for the wl12xx driver, but as the driver is not configured, a stub function is used which simply returns -ENOSYS. Let's do the simple thing for -rc and print the error code. Also, the return code from platform_register_device() at each of these sites was not being checked. Add some checking, and again print the error code. This should be fixed properly for the next merge window so we don't issue error messages merely because a driver is not configured.

Found by review. omap4_sdp4430_wifi_mux_init() is called by an __init marked function, and only calls omap_mux_init_gpio() and omap_mux_init_signal() which are both also an __init marked functions. The only reason this doesn't issue a warning is because the compiler inlines omap4_sdp4430_wifi_mux_init() into omap4_sdp4430_wifi_init().

2012-02-13ARM: omap: fix uninformative vc/i2c configuration error messageRussell King1-2/+2
On my OMAP4 platform, I'm getting this error message repeated several times at boot: omap_vc_i2c_init: I2C config for all channels must match. omap_vc_i2c_init: I2C config for all channels must match. This doesn't help identify what the problem is. Fix this message to be more informative: omap_vc_i2c_init: I2C config for vdd_iva does not match other channels (0). omap_vc_i2c_init: I2C config for vdd_mpu does not match other channels (0). This allows us to identify which voltage domains have a problem, and what the I2C configuration state (a boolean, i2c_high_speed) setting being used actually is. From this we find that omap4_core_pmic has i2c_high_speed false, but omap4_iva_pmic and omap4_mpu_pmic both have it set true.

When eSDHC module is enabled on P5020/P3041/P2041/P1010 with eSDHC version 2.3, there is following errors: mmc0: Timeout waiting for hardware interrupt. mmc0: error -110 whilst initialising SD card mmc0: Unexpected interrupt 0x02000000. mmc0: Timeout waiting for hardware interrupt. mmc0: error -110 whilst initialising SD card mmc0: Unexpected interrupt 0x02000000. It is because eSDHC controller has different bit setting for PROCTL register at 0x28 comparing SD specification. This patch sets DMAS bits correctly for byte operation and does not change the default value of other field of PROCTL register. For other FSL chips, such as MPC8536/P2020, PROCTL[DMAS] bits are reserved and even if they are set to wrong bits, it will not take effective.

Quoth David: 1) GRO MAC header comparisons were ethernet specific, breaking other link types. This required a multi-faceted fix to cure the originally noted case (Infiniband), because IPoIB was lying about it's actual hard header length.

From Anisse Astier. 3) Off by ones and other bug fixes in netprio_cgroup from Neil Horman. 4) ipv4 TCP reset generation needs to respect any network interface binding from the socket, otherwise route lookups might give a different result than all the other segments received.

Commit 653241 (net: RFC3069, private VLAN proxy arp support) changed the behavior of arp proxy to send arp replies back out on the interface the request came in even if the private VLAN feature is disabled. Previously we checked rt->dst.dev != skb->dev for in scenarios, when proxy arp is enabled on for the netdevice and also when individual proxy neighbour entries have been added.

2012-02-10xfs: use a normal shrinker for the dquot freelistChristoph Hellwig6-282/+141
Stop reusing dquots from the freelist when allocating new ones directly, and implement a shrinker that actually follows the specifications for the interface. The shrinker implementation is still highly suboptimal at this point, but we can gradually work on it. This also fixes an bug in the previous lock ordering, where we would take the hash and dqlist locks inside of the freelist lock against the normal lock ordering. This is only solvable by introducing the dispose list, and thus not when using direct reclaim of unused dquots for new allocations. As a side-effect the quota upper bound and used to free ratio values in /proc/fs/xfs/xqm are set to 0 as these values don't make any sense in the new world order.
