[patch V2 0/6] x86/irq: Cure various interrupt issues
From: Thomas Gleixner
Date: Fri Jun 28 2019 - 07:22:11 EST
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
Changes vs. V1: Use the existing irq_get_irqchip_state() callback
Fixup misleading comments
Use the sync scheme in synchronize_irq() as well.
Thanks,
tglx
