Ah, sorry - due to:

 commit ee4c24a5c9b530481394132c8dbc10572d57c075
 Merge: 3d58f48... 3e0c373...
 Author: Ingo Molnar <mingo@...e.hu>
 Date:   Mon Jun 1 22:29:35 2009 +0200

    Merge branch 'x86/cpufeature' into irq/numa
    
    Merge reason: irq/numa didnt build because this commit:
    
      2759c32: x86: don't call read_apic_id if !cpu_has_apic
    
    Had a dependency on x86/cpufeature changes. Pull in that
    (small) branch to fix the dependency.
    
    Signed-off-by: Ingo Molnar <mingo@...e.hu>

This seemed like one of the exceptions to do that merge - 
x86/cpufeature is a narrow 'infrastructure' topic we keep around 
during the development window, because we found it in the past that 
cpufeature changes frequently cause conflicts and merge 
dependencies. The cpufeatres commits are always kept uninteresting 
and non-controversial.

So technically it's a cross-tree merge, but of the good and 
exceptional kind ... i hope :-/

Thanks :)

There are none planned! :-)
