[patch 00/29] arm: bug fixes and irq cleanup (v2) for .39

[Thomas Gleixner]

The following series contains a few bugfixes, which I made in order to
compile the irq cleanup series.

The irq cleanup series is almost the same except for a few typo fixups and
does not longer remove the tegra resume/suspend stuff, but removes the irq
fiddling inside.

For your conveniance the series is also available from:

    git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip.git irq/for-arm

once the mirror decided to sync.

Please let me know how to proceed with this lot.

Thanks,

	tglx

This will cause warnings in both the suspend and resume functions as i
is now unused.

Do you want me to take this through the Tegra tree for 2.6.39-rc1?
