2008-02-08[POWERPC] Add arch-specific walk_memory_remove() for 64-bit powerpcBadari Pulavarty
walk_memory_resource() verifies if there are holes in a given memory range, by checking against /proc/iomem. On x86/ia64 system memory is represented in /proc/iomem. On powerpc, we don't show system memory as IO resource in /proc/iomem - instead it's maintained in /proc/device-tree. This provides a way for an architecture to provide its own walk_memory_resource() function. On powerpc, the memory region is small (16MB), contiguous and non-overlapping. So extra checking against the device-tree is not needed.

2008-02-08[POWERPC] Make cell IOMMU fixed mapping printk more usefulMichael Ellerman
Currently the cell IOMMU fixed mapping just printks that it's been setup, which is not particularly useful. Much more interesting is the address ranges for the different windows. This adds one line to dmesg on a blade. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
2008-02-08[POWERPC] Fix potential cell IOMMU bug when switching back to default DMA opsMichael Ellerman
If we get a 64-bit dma mask we switch to the fixed ops and call cell_dma_dev_setup(). If the driver then switches back to a 32-bit dma mask for any reason we don't call cell_dma_dev_setup() again, which has the potential to leave bogus data in dev->archdata.dma_data.

2008-02-08[POWERPC] Don't enable cell IOMMU fixed mapping if there are no dma-rangesMichael Ellerman
In order for the cell IOMMU fixed mapping to work we need "dma-ranges" properties in the device tree. If there are none then there's no point enabling the fixed mapping support. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
2008-02-08[POWERPC] Fix cell IOMMU null pointer explosion on old firmwaresMichael Ellerman

2008-02-08[POWERPC] spufs: Fix timing dependent false return from spufs_run_spuLuke Browning
Stop bits are only valid when the running bit is not set. Status bits carry over from one invocation of spufs_run_spu() to another, so the RUNNING bit gets added to the previous state of the register which may have been a remote library call. In this case, it looks like another library routine should be invoked, but the spe is actually running. This fixes a problem with a testcase that exercises the scheduler.

2008-02-08[POWERPC] spufs: Update SPU_Status[CISHP] in backing runcntl writeMasato Noguchi
Currently, the kernel may fail to restart a SPE context which has stopped and been swapped out. This changes spu_backing_runcntl_write to emulate the real SPU_Status register exactly. When the SPU Run Control register is written with SPU_RunCntl[Run] set to '1', the physical SPU automatically sets SPU_Status[R] and clears SPU_Status[CISHP].

2008-02-08[POWERPC] Disable G5 NAP mode during SMU commands on U3Benjamin Herrenschmidt
It appears that with the U3 northbridge, if the processor is in NAP mode the whole time while waiting for an SMU command to complete, then the SMU will fail. It could be related to the weird backward mechanism the SMU uses to get to system memory via i2c to the northbridge that doesn't operate properly when the said bridge is in napping along with the CPU. That is on U3 at least, U4 doesn't seem to be affected. This didn't show before NO_HZ as the timer wakeup was enough to make it work it seems, but that is no longer the case. This fixes it by disabling NAP mode on those machines while an SMU command is in flight.

2008-02-01suspend: cleanup reference to swsusp_pg_dir[]Rafael J. Wysocki
swsusp_pg_dir[] is used for suspend, but not for hibernation. clean-up the ifdefs which worked by accident, while implying the opposite. Delete the __nosavedata, which also implied the opposite.

2008-02-01Suspend: Introduce begin() and end() callbacksRafael J. Wysocki
On ACPI systems the target state set by acpi_pm_set_target() is reset by acpi_pm_finish(), but that need not be called if the suspend fails.  All platforms that use the .set_target() global suspend callback are affected by analogous issues. For this reason, we need an additional global suspend callback that will reset the target state regardless of whether or not the suspend is successful.  Also, it is reasonable to rename the .set_target() callback, since it will be used for a different purpose on ACPI systems (due to ACPI 1.0x code ordering requirements). Introduce the global suspend callback .end() to be executed at the end of the suspend sequence and rename the .set_target() global suspend callback to .begin(). Signed-off-by: Rafael J.
