Ah, sorry - due to:

commit ee4c24a5c9b530481394132c8dbc10572d57c075
Merge: 3d58f48... 3e0c373...
Author: Ingo Molnar <mingo@xxxxxxx>
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@xxxxxxx>

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 :)
