Subject: [patch 17/33] x86/apic/msi: Remove arch_create_remap_msi_irq_domain()
Date: Fri, 11 Nov 2022 14:58:38 +0100 (CET) [thread overview]
Message-ID: <20221111135206.234039487@linutronix.de> (raw)
In-Reply-To: 20221111133158.196269823@linutronix.de
and related code which is not longer required now that the interrupt remap
code has been converted to MSI parent domains.
