* [POWERPC] Bypass hcall stats until cpu features have runAnton Blanchard2007-03-22
| | | | | | | | | | I noticed that we execute hcalls before cpu feature code has run (eg for setting up the bolted kernel region). This means that we may be executing code that is not appropriate for the processor we have. Create an unconditional branch that we nop out all the time to fix this.

* [POWERPC] Avoid hypervisor statistics calculation in real modeMohan Kumar M2007-03-22
| | | | | | | | | | | | | | kexec invokes plpar_hcall hypervisor call in real mode. plpar_hcall refers to per cpu variables for accounting hypervisor statistics. These variables may not be in the RMO region, so accesses to them in real mode may result in a data storage exception. This fixes this problem by using a new plpar_hcall_raw function which does not update the hypervisor call statistics. Thanks to Anton for suggesting this idea.

* [POWERPC] Fix spu SLB invalidationsBenjamin Herrenschmidt2007-03-09
| | | | | | | | | | | | | | | | | The SPU code doesn't properly invalidate SPUs SLBs when necessary, for example when changing a segment size from the hugetlbfs code. In addition, it saves and restores the SLB content on context switches which makes it harder to properly handle those invalidations. This patch removes the saving & restoring for now, something more efficient might be found later on. It also adds a spu_flush_all_slbs(mm) that can be used by the core mm code to flush the SLBs of all SPEs that are running a given mm at the time of the flush. In order to do that, it adds a spinlock to the list of all SPEs and move some bits & pieces from spufs to spu_base.c Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

* mv643xx_eth: Place explicit port number in mv643xx_eth_platform_dataDale Farnsworth2007-03-06
| | | | | | | | | | | | | | We were using the platform_device.id field to identify which ethernet port is used for mv643xx_eth device. This is not generally correct. It will be incorrect, for example, if a hardware platform uses a single port but not the first port. Here, we add an explicit port_number field to struct mv643xx_eth_platform_data. This makes the mv643xx_eth_platform_data structure required, but that isn't an issue since all users currently provide it already.

* [PATCH] msi: sanely support hardware level msi disablingEric W. Biederman2007-03-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | In some cases when we are not using msi we need a way to ensure that the hardware does not have an msi capability enabled. Currently the code has been calling disable_msi_mode to try and achieve that. However disable_msi_mode has several other side effects and is only available when msi support is compiled in so it isn't really appropriate. Instead this patch implements pci_msi_off which disables all msi and msix capabilities unconditionally with no additional side effects. pci_disable_device was redundantly clearing the bus master enable flag and clearing the msi enable bit. A device that is not allowed to perform bus mastering operations cannot generate intx or msi interrupt messages as those are essentially a special case of dma, and require bus mastering. So the call in pci_disable_device to disable msi capabilities was redundant. quirk_pcie_pxh also called disable_msi_mode and is updated to use pci_msi_off. Signed-off-by: Eric W.

* backlight: Separate backlight properties from backlight ops pointersRichard Purdie2007-02-20

* backlight: Fix external uses of backlight internal semaphoreRichard Purdie2007-02-20
| | | | | | | | | | | | | | | | | | backlight_device->sem has a very specific use as documented in the header file. The external users of this are using it for a different reason, to serialise access to the update_status() method. backlight users were supposed to implement their own internal serialisation of update_status() if needed but everyone is doing things differently and incorrectly. Therefore add a global mutex to take care of serialisation for everyone, once and for all. Locking for get_brightness remains optional since most users don't need it. Also update the lcd class in a similar way. Signed-off-by: Richard Purdie <rpurdie@rpsys.net>

In the current setup, it isn't possible to poweron when power is restored. This patch fixes the issue by calling the right ibm,power-off-ups token during such events. It also adds a sysfs interface so userspace can specify whether or not to power on when power is restored.
