Here's a dumb simple implementation of fake NUMA nodes for PowerPC. Fake NUMA nodes can be specified using the following command line option numa=fake=<node range> node range is of the format <range1>,<range2>,...<rangeN> Each of the rangeX parameters is passed using memparse(). I find this useful for fake NUMA emulation on my simple PowerPC machine. I've tested it on a non-numa box with the following arguments: numa=fake=1G numa=fake=1G,2G name=fake=1G,512M,2G numa=fake=1500M,2800M mem=3500M numa=fake=1G mem=512M numa=fake=1G mem=1G Signed-off-by: NBalbir Singh <balbir@linux.vnet.ibm.com> Acked-by: NOlof Johansson <olof@lixom.net> Signed-off-by: NPaul Mackerras <paulus@samba.org>

Optimize MPIC IPIs, by passing in the IPI number as the argument to the handler, since all we did was translate it back based on which mpic the interrupt came though on (and that was always the primary mpic).

Currently, we have a possibilty that the SLBs setup during context switch don't cover the entirety of the necessary lscsa and code regions, if these regions cross a segment boundary. This change checks the start and end of each region, and inserts a SLB entry for each, if unique. We also remove the assumption that the spu_save_code and spu_restore_code reside in the same segment, by using the specific code array for save and restore.

Currently, the SPU context switch code (spufs/switch.c) sets up the SPU's SLBs directly, which requires some low-level mm stuff. This change moves the kernel SLB setup to spu_base.c, by exposing a function spu_setup_kernel_slbs() to do this setup. This allows us to remove the low-level mm code from switch.c, making it possible to later move switch.c to the spufs module. Also, add a struct spu_slb for the cases where we need to deal with SLB entries. Signed-off-by: NJeremy Kerr <jk@ozlabs.org> Signed-off-by: NArnd Bergmann <arnd@arndb.de>

The pm_interval register in the Cell PMU is read/write, but was implemented in the kernel as write-only. Previously, the written value was saved in a "shadow" copy so calls to cbe_read_pm() could return the value. Perfmon2 needs to be able to read the current values of pm_interval, so change cbe_read_pm() to read the actual register instead of the "shadow" copy. There is currently no code in the kernel that tries to read the pm_interval register with cbe_read_pm() (expecting to receive the "shadow" value), so this should not break any existing code.

Updates the ucc_geth device driver to check the new rx-clock-name and tx-clock-name properties first. If present, it uses the new function qe_clock_source() to obtain the clock source. Otherwise, it checks the deprecated rx-clock and tx-clock properties. Update the device trees for 832x, 836x, and 8568 to contain the new property names only.

This makes the early debug option force the console loglevel to the max. The early debug option is meant to catch messages very early in the kernel boot process, in many cases, before the kernel has a chance to parse the "debug" command line argument. Thus it makes sense when CONFIG_PPC_EARLY_DEBUG is set, to force the console log level to the max at boot time.

The 32 bits PCI code will display a rather scary error message PCI: Cannot allocate resource region N of device XXX at boot when the existing setup of a device as left by the firmware doesn't match the kernel needs and the device needs to be moved. This is often not an error at all, as the kernel will generally easily reallocate the device elsewhere. This changes the message to something less scary and lowers its level from error to warning.

The 32-bit powerpc resource fixup code uses unsigned longs to do the offsetting of resources which overflows on platforms such as 4xx where resources can be 64 bits. This fixes it by using resource_size_t instead. However, the IO stuff does rely on some 32 bits arithmetic, so we hack by cropping the result of the fixups for IO resources with a 32 bits mask. This isn't the prettiest but should work for now until we change the 32 bits PCI code to do IO mappings like 64 bits does, within a reserved are of the kernel address space.

This merges the 32-bit and 64-bit implementations of pci_process_bridge_OF_ranges(). The new function is cleaner than both the old ones, and supports 64 bits ranges on ppc32 which is necessary for the 4xx port. It also adds some better (hopefully) output to the kernel log which should help diagnose problems and makes better use of existing OF parsing helpers (avoiding a few bugs of both implementations along the way). There are still a few unfortunate ifdef's but there is no way around these for now at least not until some other bits of the PCI code are made common.
