Subject: Re: [PATCH] x86: arch_probe_nr_irqs

Very cool, thanks!!

The one thing I always get hung up on is what args to use with the git
rebase -i command.  Say I want to edit 4a046d1 (which I do ;-), I see
it in my repo with git-log (3rd one down):

commit e46d517...
Merge: a4a0acf... 4a046d1...
Author: Ingo Molnar <mingo@...e.hu>

    Merge branch 'master' of ssh://master.kernel.org/pub/scm/linux/kernel/git/travis/linux-2.6-cpus4096-for-ingo into cpus4096

commit a4a0acf...
Author: Suresh Siddha <suresh.b.siddha@...el.com>

    x86: fix broken flush_tlb_others_ipi()

commit 4a046d1...
Author: Yinghai Lu <yinghai@...nel.org>

    x86: arch_probe_nr_irqs

commit e65e49d...
Author: Mike Travis <travis@....com>

    irq: update all arches for new irq_desc


So, upstream is tip/cpus4096 yes?  But then:

: git-rebase -i tip/cpus4096
Nothing to do

Attempting other args proved equally fruitless.

Thanks,
Mike
