Date: Fri, 9 Dec 2022 15:01:43 +0100 From: Johan Hovold <johan+linaro@...nel.org> To: Marc Zyngier <maz@...nel.org> Cc: Thomas Gleixner <tglx@...utronix.de>, x86@...nel.org, platform-driver-x86@...r.kernel.org, linux-arm-kernel@...ts.infradead.org, linux-mips@...r.kernel.org, linux-kernel@...r.kernel.org, Johan Hovold <johan+linaro@...nel.org> Subject: [PATCH v3 12/19] x86/apic: Use irq_domain_create_hierarchy() Use the irq_domain_create_hierarchy() helper to create the hierarchical domain, which both serves as documentation and avoids poking at irqdomain internals.
