Subject: [PATCH 02/11] powerpc/pseries: put cede MSR[EE] check under IRQ_SOFT_MASK_DEBUG
Date: Sat,  5 May 2018 03:19:26 +1000	[thread overview]
Message-ID: <20180504171935.25410-3-npiggin@gmail.com> (raw)
In-Reply-To: <20180504171935.25410-1-npiggin@gmail.com>

This check does not catch IRQ soft mask bugs, but this option is
slightly more suitable than TRACE_IRQFLAGS.
