2011-10-31powerpc: Fix up modules that should be including module.hPaul Gortmaker
So that we can clean up the header files and not be relying on implicit includes from device.h ---> module.h Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
2011-10-31powerpc: add export.h to files making use of EXPORT_SYMBOLPaul Gortmaker
With module.h being implicitly everywhere via device.h, the absence of explicitly including something for EXPORT_SYMBOL went unnoticed. Since we are heading to fix things up and clean module.h from the device.h file, we need to explicitly include these files now. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
2011-10-31x86: fix up files really needing to include module.hPaul Gortmaker
These files aren't just exporting symbols -- they are also defining a MODULE_LICENSE etc. so give them the full module.h file. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
2011-10-31acpi: add export.h to files using THIS_MODULE/EXPORT_SYMBOLPaul Gortmaker
These files were relying on module.h to come in via the path in an include/acpi header file, but we don't want to have instances of module.h being included from include/* files if it can be avoided. Have the files include export.h instead. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
2011-10-31acpi: downgrade files from module.h to export.h where possible.Paul Gortmaker
If a file is only exporting symbols and not using the core modular infrastructure, it can get by with just including the smaller export.h header, which is a lot smaller than the module.h header. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
2011-10-31acpi: delete module.h include from files explicitly not needing itPaul Gortmaker
Files which aren't actually using infrastructure from module.h shouldn't include it, as it is a big header with lots of child includes spawned off. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
2011-10-31acpi: add module.h to files implicitly using/relying on it.Paul Gortmaker
These files are using standard module API things like MODULE_AUTHOR etc. and so should not be relying on an implicit presence of the module.h header. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>

2011-10-30i2c-algo-bit: Let user test buses without failingJean Delvare
Always failing to register I2C buses when the line testing fails is a little harsh. While such a failure is definitely a bug in the driver that exposes the affected I2C bus, things may still work fine if the missing initialization steps are done later, before the I2C bus is used. So it seems a better debugging tool to just report the test failure by default. I introduce bit_test=2 if anyone really misses the original behavior of bit_test=1.

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.

2011-10-27Revert "drm/radeon/kms: add a new gem_wait ioctl with read/write flags"Dave Airlie
This reverts commit d3ed74027f1dd197b7e08247a40d3bf9be1852b0. Further upstream discussion between Thomas and Marek decided this needed more work and driver specifics. So revert before it goes upstream. Signed-off-by: Dave Airlie <airlied@redhat.com>
2011-10-27mmc: core: Cleanup eMMC4.5 conditionalsSeungwon Jeon
Code cleanup, putting all eMMC 4.5 detection cases together. This patch removes one if-statement and assembles all. And it also removes variable initialization below else-statement -- all members of card structure are already set to zero at card-init.

2011-10-27mmc: core: add workaround for controllers with broken multiblock readsPaul Walmsley
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. See for example Advisory 2.1.1.128 "MMC: Multiple Block Read Operation Issue" in _OMAP3530/3525/3515/3503 Silicon Errata_ Revision F (October 2010) (SPRZ278F), available from http://focus.ti.com/lit/er/sprz278f/sprz278f.pdf Signed-off-by: Paul Walmsley <paul@pwsan.com> Cc: Dave Hylands <dhylands@gmail.com> Tested-by: Steve Sakoman <sakoman@gmail.com> Signed-off-by: Chris Ball <cjb@laptop.org>

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.
