Subject: [patch 0/5] x86/irq: Cure various interrupt issues

This series addresses a few long standing issues:

  1) The spurious interrupt warning which is emitted occasionally for
     no obvious reason. Partially harmless but annoying

  2) The spurious system vector detection which got wreckaged quite some
     time ago and can completely wedge a machine. Posted yesterday already
     in a preliminary version. Now actually verified that it does what it
     claims to do.

Details in the various patches.

For your conveniance the series is available from git:

    git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git WIP.irq

Thanks,

	tglx
