2011-10-27pci: Clamp pcie_set_readrq() when using "performance" settingsBenjamin Herrenschmidt
When configuring the PCIe settings for "performance", we allow parents to have a larger Max Payload Size than children and rely on children Max Read Request Size to not be larger than their own MPS to avoid having the host bridge generate responses they can't cope with. However, various drivers in Linux call pci_set_readrq() with arbitrary values, assuming this to be a simple performance tweak. This breaks under our "performance" configuration. Fix that by making sure the value programmed by pcie_set_readrq() is never larger than the configured MPS for that device.

Also, rework the MRRS setting to report an inability to set the MRRS to a valid setting.

2011-10-27PCI: Workaround for Intel MPS errataJon Mason
Intel 5000 and 5100 series memory controllers have a known issue if read completion coalescing is enabled and the PCI-E Maximum Payload Size is set to 256B. To work around this issue, disable read completion coalescing in the memory controller and root complexes. Unfortunately, it must always be disabled, even if no 256B MPS devices are present, due to the possibility of one being hotplugged.

Due to hardware bugs, some MMC host controllers don't support multiple-block reads[1]. To resolve, add a new MMC capability flag, MMC_CAP2_NO_MULTI_READ, which can be set by affected host controller drivers. When this capability is set, all reads will be issued one sector at a time. 1.

2011-10-27lguest: move process freezing before pending signals checkMichal Hocko
run_guest tries to freeze the current process after it has handled pending interrupts and before it calls lguest_arch_run_guest. This doesn't work nicely if the task has been killed while being frozen and when we want to handle that signal as soon as possible. Let's move try_to_freeze before we check for pending signal so that we can get out of the loop as soon as possible.

2011-10-26gpio: pl061: add DT binding supportRob Herring
This adds devicetree binding support to the ARM pl061 driver removing the platform_data dependency. When DT binding is used, the gpio numbering is assigned dynamically. For now, interrupts are not supported with DT until irqdomains learn dynamic irq assignment. Rather than add another case of -1, updating the driver to use NO_IRQ.

2011-10-26mmc: core: Prevent too long response times for suspendUlf Hansson
While trying to suspend the mmc host there could still be ongoing requests that we need to wait for. At the same time a device driver must respond to a suspend request rather quickly. Instead of potentially wait "forever" by claiming the host we now "try" to claim the host instead. If it fails, -EBUSY is returned.

2011-10-26mmc: sd: Handle SD3.0 cards not supporting UHS-I bus speed modeSubhash Jadavani
Here is Essential conditions to indicate Version 3.00 Card (SD_SPEC=2 and SD_SPEC3=1) : (1) The card shall support CMD6 (2) The card shall support CMD8 (3) The card shall support CMD42 (4) User area capacity shall be up to 2GB (SDSC) or 32GB (SDHC) User area capacity shall be more than or equal to 32GB and up to 2TB (SDXC) (5) Speed Class shall be supported (SDHC or SDXC) So even if SD card doesn't support any of the newly defined UHS-I bus speed mode, it can advertise itself as SD3.0 cards as long as it supports all the essential conditions of SD3.0 cards. Given this, these type of cards should atleast run in High Speed mode @50MHZ if it supports HS. But current initialization sequence for SD3.0 cards is such that these non-UHS-I SD3.0 cards runs in Default Speed mode @25MHz. This patch makes sure that these non-UHS-I SD3.0 cards run in High Speed Mode @50MHz. Tested this patch with SanDisk Extreme SDHC 8GB Class 10 card.

This patch adds support for the power off notify feature, available in eMMC 4.5 devices. If the host has support for this feature, then the mmc core will notify the device by setting the POWER_OFF_NOTIFICATION byte in the extended csd register with a value of 1 (POWER_ON). For suspend mode short timeout is used, whereas for the normal poweroff long timeout is used.

Ths patch allows runtime PM for sdhci-pci, runtime suspending after inactivity of 50ms and ensuring runtime resume before SDHC registers are accessed. During runtime suspend, interrupts are masked. The host controller state is restored at runtime resume. For Medfield, the host controller's card detect mechanism is supplanted by an always-on GPIO which provides for card detect wake-up.

2011-10-26mmc: core: move ->request() call from atomic contextAdrian Hunter
mmc_request_done() is sometimes called from interrupt or other atomic context. Mostly all mmc_request_done() does is complete(), however it contains code to retry on error, which uses ->request(). As the error path is certainly not performance critical, this may be moved to the waiting function mmc_wait_for_req_done(). This allows ->request() to use runtime PM get_sync() and guarantee it is never in an atomic context.
