lockdep/selftests: Fix selftests vs PROVE_RAW_LOCK_NESTING
When PROVE_RAW_LOCK_NESTING=y many of the selftests FAILED because HARDIRQ context is out-of-bounds for spinlocks. Instead make the default hardware context the threaded hardirq context, which preserves the old locking rules. The wait-type specific locking selftests will have a non-threaded HARDIRQ variant. Fixes: de8f5e4f2dc1 ("lockdep: Introduce wait-type checks") Signed-off-by: Peter Zijlstra (Intel) <peterz@infradead.org> Tested-by: Joerg Roedel <jroedel@suse.de> Link: https://lore.kernel.org/r/20210617190313.322096283@infradead.org
