2011-03-04powerpc/pseries: Add support for dynamic dma windowsNishanth Aravamudan
If firmware allows us to map all of a partition's memory for DMA on a particular bridge, create a 1:1 mapping of that memory. Add hooks for dealing with hotplug events. Dynamic DMA windows can use larger than the default page size, and we use the largest one possible.

2011-03-02powerpc: Mask smp_processor_id() false positivePaul E. McKenney
The rtas_event_scan() function uses smp_processor_id() to select a starting point in cpu_online_mask, and does so under the protection of get_online_cpus(). This might not select the current processor in any case, so switch to raw_smp_processor_id(). Signed-off-by: Paul E.

2011-02-07powerpc: Fix hcall tracepoint recursionAnton Blanchard
Spinlocks on shared processor partitions use H_YIELD to notify the hypervisor we are waiting on another virtual CPU. Unfortunately this means the hcall tracepoints can recurse. The patch below adds a percpu depth and checks it on both the entry and exit hcall tracepoints.

2011-02-07powerpc/numa: Fix bug in unmap_cpu_from_nodeAnton Blanchard
When converting to the new cpumask code I screwed up: - if (cpu_isset(cpu, numa_cpumask_lookup_table[node])) { - cpu_clear(cpu, numa_cpumask_lookup_table[node]); + if (cpumask_test_cpu(cpu, node_to_cpumask_map[node])) { + cpumask_set_cpu(cpu, node_to_cpumask_map[node]); This was introduced in commit 25863de07af9 (powerpc/cpumask: Convert NUMA code to new cpumask API) Fix it.

2011-02-07powerpc/numa: Disable VPHN on dedicated processor partitionsAnton Blanchard

2011-02-07powerpc/numa: Add length when creating OF properties via VPHNAnton Blanchard
The rest of the NUMA code expects an OF associativity property with the first cell containing the length. Without this fix all topology changes cause us to misparse the property and put the cpu into node 0.

2011-02-07powerpc/numa: Check for all VPHN changesAnton Blanchard
The hypervisor uses unsigned 1 byte counters to signal topology changes to the OS. Since they can wrap we need to check for any difference, not just if the hypervisor count is greater than the previous count.

2011-02-07powerpc/numa: Only use active VPHN count fieldsAnton Blanchard
VPHN supports up to 8 distance fields but the number of entries in ibm,associativity-reference-points signifies how many are in use. Don't look at all the VPHN counts, only distance_ref_points_depth worth. Since we already cap our distance metrics at MAX_DISTANCE_REF_POINTS, use that to size the VPHN arrays and add a BUILD_BUG_ON to avoid it growing larger than the VPHN maximum of 8.

2011-02-07powerpc: Fix some 6xx/7xxx CPU setup functionsBenjamin Herrenschmidt
Some of those functions try to adjust the CPU features, for example to remove NAP support on some revisions. However, they seem to use r5 as an index into the CPU table entry, which might have been right a long time ago but no longer is. r4 is the right register to use. This probably caused some off behaviours on some PowerMac variants using 750cx or 7455 processor revisions. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> CC: stable@kernel.org
2011-02-07powerpc: Pass the right cpu_spec to ->setup_cpu() on 64-bitBenjamin Herrenschmidt
When calling setup_cpu() on 64-bit, we pass a pointer to the cputable entry we have found. This used to be fine when cur_cpu_spec was a pointer to that entry, but nowadays, we copy the entry into a separate variable, and we do so before we call the setup_cpu() callback. That means that any attempt by that callback at patching the CPU table entry (to adjust CPU features for example) will patch the wrong table.
