Subject: [patch 1/5] ARC: Remove GENERIC_PENDING_IRQ
Date: Tue, 10 Dec 2024 11:34:10 +0100 (CET)	[thread overview]
Message-ID: <20241210103335.373392568@linutronix.de> (raw)
In-Reply-To: <20241210102148.760383417@linutronix.de>

Nothing uses the actual functionality and the MCIP controller sets the
flags which disables the deferred affinity change. The other interrupt
controller does not support affinity setting at all.
