Subject: [PATCH v4 08/23] powerpc/irq: Add helper to set regs->softe
Date: Mon, 25 Jan 2021 14:48:21 +0000 (UTC)	[thread overview]
Message-ID: <e1961d698ee434a429117884f8d6ebd8383dc41d.1611585031.git.christophe.leroy@csgroup.eu> (raw)
In-Reply-To: <cover.1611585031.git.christophe.leroy@csgroup.eu>

regs->softe doesn't exist on PPC32.

Add irq_soft_mask_regs_set_state() helper to set regs->softe.
This helper will void on PPC32.
