* [POWERPC] iSeries: Fix unregistering HV event handlersStephen Rothwell2007-12-20
| | | | | | | | | | | | Commit fbd568a3e61a7decb8a754ad952aaa5b5c82e9e5 ("Change synchronize_kernel to _rcu and _sched") changed the deprecated synchronize_kernel() in HvLpEvent_unregisterHandler() to synchronize_rcu(). It turns out that it should have been synchronize_sched(). Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Acked-by: Paul E.

* [POWERPC] wrapper: Treat NULL as root node in devp_offset; add ↵Scott Wood2007-12-20
| | | | | | | | | | | | | devp_offset_find() Many operations, as currently used in the wrapper, assume they can pass NULL and have it be treated as the root node. However, libfdt-wrapper converts NULL to -1, which is only appropriate when searching for nodes, and will cause an error otherwise.

| | | | | | | | | | | | fdt_wrapper_create_node passes a variable called offset to offset_devp(), which uses said parameter to initialize a local variable called offset. Due to one of the odder aspects of the C language, the result is an undefined variable, with no error or warning.

* [POWERPC] Fake NUMA emulation for PowerPCBalbir Singh2007-12-20
| | | | | | | | | | | | | | | | | | | | | | | | 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: Balbir Singh <balbir@linux.vnet.ibm.com> Acked-by: Olof Johansson <olof@lixom.net> Signed-off-by: Paul Mackerras <paulus@samba.org>

| * [POWERPC] cell: handle SPE kernel mappings that cross segment boundariesJeremy Kerr2007-12-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Jeremy Kerr <jk@ozlabs.org> Signed-off-by: Arnd Bergmann <arnd@arndb.de>

| * [POWERPC] perfmon2: make pm_interval register read/writeKevin Corry2007-12-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | This makes the early debug option force the console loglevel to the max.

* [POWERPC] Fix powerpc 32-bit resource fixup for 64-bit resourcesBenjamin Herrenschmidt2007-12-10
| | | | | | | | | | | | | | | | | | | 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.

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.
