Subject: [PATCH v4 07/17] hw, target, accel: whpx: change apic_in_platform to kernel_irqchip
Date: Mon,  4 Aug 2025 16:23:16 +0200	[thread overview]
Message-ID: <20250804142326.72947-8-mohamed@unpredictable.fr> (raw)
In-Reply-To: <20250804142326.72947-1-mohamed@unpredictable.fr>

Change terminology to match the KVM one, as APIC is x86-specific.

Signed-off-by: Mohamed Mediouni <mohamed@unpredictable.fr>
