2011-01-21perf: Annotate cpuctx->ctx.mutex to avoid a lockdep splatPeter Zijlstra1-0/+3
Lockdep spotted: loop_1b_instruc/1899 is trying to acquire lock: (event_mutex){+.+.+.}, at: [<ffffffff810e1908>] perf_trace_init+0x3b/0x2f7 but task is already holding lock: (&ctx->mutex){+.+.+.}, at: [<ffffffff810eb45b>] perf_event_init_context+0xc0/0x218 which lock already depends on the new lock. the existing dependency chain (in reverse order) is: -> #3 (&ctx->mutex){+.+.+.}: -> #2 (cpu_hotplug.lock){+.+.+.}: -> #1 (module_mutex){+.+...}: -> #0 (event_mutex){+.+.+.}: But because the deadlock would be cpuhotplug (cpu-event) vs fork (task-event) it cannot, in fact, happen. We can annotate this by giving the perf_event_context used for the cpuctx a different lock class from those used by tasks.

2011-01-21x86, mcheck, therm_throt.c: Export symbol platform_thermal_notify to allow ↵Fenghua Yu1-0/+1
coretemp to handler intr In therm_throt.c, commit 9e76a97efd31a08cb19d0ba12013b8fb4ad3e474 patch doesn't export the symbol platform_thermal_notify. Other drivers (e.g. drivers/hwmon/coretemp.c) can not find the symbol platform_thermal_notify when defining threshould interrupt handler. Please apply this patch to allow threshold interrupt handler in coretemp.

2011-01-21powerpc: machine_check_generic is wrong on 64bitAnton Blanchard1-23/+0
Decoding machine checks is CPU specific and so machine_check_generic doesn't do the right thing on 64bit chips. Luckily we never call into this code because we call ppc_md.machine_check_exception instead if available. Since we check cur_cpu_spec->machine_check before calling it, we may as well remove machine_check_generic from 64bit archs.

2011-01-21powerpc: Fix corruption when grabbing FWNMI dataAnton Blanchard1-14/+38
The FWNMI code uses a global buffer without any locks to read the RTAS error information. If two CPUs take a machine check at once then we will corrupt this buffer. Since most FWNMI rtas messages are not of the extended type, we can create a 64bit percpu buffer and use it where possible. If we do receive an extended RTAS log then we fall back to the old behaviour of using the global buffer.
