Subject: [PATCH 11/11] powerpc/microwatt: Disable interrupts in boot wrapper main program
Date: Tue, 15 Jun 2021 09:05:27 +1000 [thread overview]
Message-ID: <YMfgt4ndMrtYwWYY@thinks.paulus.ozlabs.org> (raw)
In-Reply-To: <YMfeswgEHeXSLOUF@thinks.paulus.ozlabs.org>
This ensures that we don't get a decrementer interrupt arriving before
we have set up a handler for it.
