2012-02-14ARM: OMAP4: Move the barrier memboclk_steal() as part of reserve callbackSantosh Shilimkar
arm_memblock_steal() is not suppose to be used outside ->reserve callback. OMAP barrier errata code was using it outside reserve callback and hence it was broken. Move the allocation as part of ->reserve callback to fix the it. Signed-off-by: Santosh Shilimkar <santosh.shilimkar@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

2012-02-14tcp: fix tcp_shifted_skb() adjustment of lost_cnt_hint for FACKNeal Cardwell
This commit ensures that lost_cnt_hint is correctly updated in tcp_shifted_skb() for FACK TCP senders. The lost_cnt_hint adjustment in tcp_sacktag_one() only applies to non-FACK senders, so FACK senders need their own adjustment. This applies the spirit of 1e5289e121372a3494402b1b131b41bfe1cf9b7f - except now that the sequence range passed into tcp_sacktag_one() is correct we need only have a special case adjustment for FACK.

2012-02-14USB: Don't fail USB3 probe on missing legacy PCI IRQ.Sarah Sharp
Intel has a PCI USB xhci host controller on a new platform. It doesn't have a line IRQ definition in BIOS. The Linux driver refuses to initialize this controller, but Windows works well because it only depends on MSI. Actually, Linux also can work for MSI. This patch avoids the line IRQ checking for USB3 HCDs in usb core PCI probe. It allows the xHCI driver to try to enable MSI or MSI-X first. It will fail the probe if MSI enabling failed and there's no legacy PCI IRQ. This patch should be backported to kernels as old as 2.6.32.

This updates the sha512 fix so that it doesn't cause excessive stack usage on i386. This is done by reverting to the original code, and avoiding the W duplication by moving its initialisation into the loop. As the underlying code is in fact the one that we have used for years, I'm pushing this now instead of postponing to the next cycle. * git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6: crypto: sha512 - Avoid stack bloat on i386 crypto: sha512 - Use binary and instead of modulus
2012-02-14powerpc/pseries/eeh: Fix crash when error happens during device probeThadeu Lima de Souza Cascardo
EEH may happen during a PCI driver probe. If the driver is trying to access some register in a loop, the EEH code will try to print the driver name. But the driver pointer in struct pci_dev is not set until probe returns successfully. Use a function to test if the device and the driver pointer is NULL before accessing the driver's name.

2012-02-13mmc: sh_mmcif: fix late delayed work initialisationGuennadi Liakhovetski
If the driver is loaded with a card in the slot, mmc_add_host() will schedule an immediate card-detection work, which will start IO and wait for command completion. Usually the kernel first returns to the sh_mmcif probe function, lets it finish and only then schedules the rescan work. But sometimes, expecially under heavy system load, the work will be scheduled immediately before returning to the probe method. In this case it is important for the driver to be fully prepared for IO. For sh_mmcif this means, that also the timeout work has to be initialised before calling mmc_add_host(). It is also better to prepare interrupts beforehand. Besides, since mmc_add_host() does card-detection itself, there is no need to do it again immediately afterwards.

2012-02-13mmc: core: Fix PowerOff Notify suspend/resumeGirish K S
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 Chung
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.
