2010-10-11x86, numa: For each node, register the memory blocks actually usedYinghai Lu
Russ reported SGI UV is broken recently. He said: | The SRAT table shows that memory range is spread over two nodes. | | SRAT: Node 0 PXM 0 100000000-800000000 | SRAT: Node 1 PXM 1 800000000-1000000000 | SRAT: Node 0 PXM 0 1000000000-1080000000 | |Previously, the kernel early_node_map[] would show three entries |with the proper node. | |[ 0.000000] 0: 0x00100000 -> 0x00800000 |[ 0.000000] 1: 0x00800000 -> 0x01000000 |[ 0.000000] 0: 0x01000000 -> 0x01080000 | |The problem is recent community kernel early_node_map[] shows |only two entries with the node 0 entry overlapping the node 1 |entry. | | 0: 0x00100000 -> 0x01080000 | 1: 0x00800000 -> 0x01000000 After looking at the changelog, Found out that it has been broken for a while by following commit |commit 8716273caef7f55f39fe4fc6c69c5f9f197f41f1 |Author: David Rientjes <rientjes@google.com> |Date: Fri Sep 25 15:20:04 2009 -0700 | | x86: Export srat physical topology Before that commit, register_active_regions() is called for every SRAT memory entry right away. Use nodememblk_range[] instead of nodes[] in order to make sure we capture the actual memory blocks registered with each node. nodes[] contains an extended range which spans all memory regions associated with a node, but that does not mean that all the memory in between are included.

2010-10-11net: clear heap allocations for privileged ethtool actionsKees Cook
Several other ethtool functions leave heap uncleared (potentially) by drivers. Some interfaces appear safe (eeprom, etc), in that the sizes are well controlled. In some situations (e.g. unchecked error conditions), the heap will remain unchanged in areas before copying back to userspace. Note that these are less of an issue since these all require CAP_NET_ADMIN.

2010-10-11ATM: iphase, remove sleep-inside-atomicJiri Slaby
Stanse found that ia_init_one locks a spinlock and inside of that it calls ia_start which calls: * request_irq * tx_init which does kmalloc(GFP_KERNEL) Both of them can thus sleep and result in a deadlock. I don't see a reason to have a per-device spinlock there which is used only there and inited right before the lock location. So remove it completely.

2010-10-11sh: oprofile: Use perf-events oprofile backendMatt Fleming
Now that we've got a generic perf-events based oprofile backend we might as well make use of it seeing as SH doesn't do anything special with its oprofile backend. Also introduce a new CONFIG_HW_PERF_EVENTS symbol so that we can fallback to using the timer interrupt for oprofile if the CPU doesn't support perf events. Also, to avoid a section mismatch warning we need to annotate oprofile_arch_exit() with an __exit marker.

2010-10-11oprofile: Abstract the perf-events backendMatt Fleming
Move the perf-events backend from arch/arm/oprofile into drivers/oprofile so that the code can be shared between architectures. This allows each architecture to maintain only a single copy of the PMU accessor functions instead of one for both perf and OProfile. It also becomes possible for other architectures to delete much of their OProfile code in favour of the common code now available in drivers/oprofile/oprofile_perf.c.
