This patch adjusts the placement of a reference context from a spu affinity chain. The reference context can now be placed only on nodes that have enough spus not intended to be used by another gang (already running on the node). Signed-off-by:

binutils < 2.18 has a bug that makes it misbehave when taking an ELF file with all segments at load address 0 as input. This happens when running "strip" on vmlinux, because of the AT() magic in this linker script. People using GCC >= 4.2 won't run into this problem, because the "build-id" support will put some data into the "notes" segment (at a non-zero load address). To work around this, we force some data into both the "dummy" segment and the kernel segment, so the dummy segment will get a non-zero load address. It's not enough to always create the "notes" segment, since if nothing gets assigned to it, its load address will be zero. Signed-off-by:

This patch changes the EEH_MAX_FAILS action from panic to printing an error message. Panicking under under this condition is too harsh. Although performance will be affected and the device may not recover, the system is still running, which at the very least should allow for a more graceful shutdown. The patch also removes the msleep() within a spinlock, which can lead to a deadlock and is not recommended. Signed-off-by:

Introduce a new dma attriblue DMA_ATTR_WEAK_ORDERING to use weak ordering on DMA mappings in the Cell processor. Add the code to the Cell's IOMMU implementation to use this code. Dynamic mappings can be weakly or strongly ordered on an individual basis but the fixed mapping has to be either completely strong or completely weak. This is currently decided by a kernel boot option (pass iommu_fixed=weak for a weakly ordered fixed linear mapping, strongly ordered is the default). Signed-off-by:

While running on a system with new hardware and a kernel where the cpu_specs[] table does not recognize the new hardware, the identify_cpu() routine will select the default case as it searches through cpu_specs[] in an attempt to match the real PVR. Once the default case is selected, non of the oprofile counters and/or fields have been set up or defined. When identify_cpu() is called once more with the logical PVR, some of the cpu specific fields are replaced with the exception of the oprofile related ones. However, in the case where we have actually taken the default case while searching for the real PVR, we need to tell oprofile that we are now running in compatibility mode so it can pick up the correct counters. We do this by setting the oprofile_cpu_type field to be that taken from the cpu_specs[] for the cpu we are now emulating. This change will detect that we are now altering the real PVR and determine if we also need to update the oprofile_cpu_type field. Signed-off-by:

The OF parsing code for PCI addresses isn't always treating properly the address space indication 0b11 (ie. 0x3) as meaning 64 bits memory space. This means that it fails to parse addresses for PCI BARs that have this encoding set by the firmware, which happens on some SLOF versions and breaks offb palette handling on Powerstation.

This patch adds support for the power button on future IBM cell blades. It actually doesn't shut down the machine. Instead it exposes an input device /dev/input/event0 to userspace which sends KEY_POWER if power button has been pressed. haldaemon actually recognizes the button, so a plattform independent acpid replacement should handle it correctly.

This patch adds a cpufreq governor that takes the number of running spus into account. It's very similar to the ondemand governor, but not as complex. Instead of hacking spu load into the ondemand governor it might be easier to have cpufreq accepting multiple governors per cpu in future. Don't know if this is the right way, but it would keep the governors simple. Signed-off-by:

Thus a NULL test or memset after calls to these functions is unnecessary. This was fixed using the following semantic patch.
