Subject: [PATCH v3 0/5] lockdep: Change IRQ state tracking to use per-cpu variables
Date: Fri, 29 May 2020 23:35:50 +0200
Message-ID: <20200529213550.683440625@infradead.org> (raw)

Ahmed and Sebastian wanted additional lockdep_assert*() macros and ran
into header hell.

Move the IRQ state into per-cpu variables, which removes the dependency on
task_struct, which is what generated the header-hell.

These patches are intended to go on top of:

 https://lkml.kernel.org/r/20200529212728.795169701@infradead.org

but should apply on current tip/master without much difficulty.

There are a few build fixes for Sparc64, PowerPC64 and s390. Especially the
Sparc one I'm not sure about.
