From 41aca705eda86f0c712f4ddc48833e4da16ff33e Mon Sep 17 00:00:00 2001 From: Andre Przywara Date: Wed, 7 Jun 2017 16:28:37 +0100 Subject: [PATCH] ARM: GIC: ITS: remove no longer needed VCPU ID in host LPI entry To get easy access to the VCPU a forwarded LPI interrupt should be injected to, so far we stored the VCPU ID in the host LPI entry. However this creates a redundancy, since we keep the target VCPU in the struct pending_irq already, which we can easily look up given the domain and the virtual LPI number. Apart from removing the redundancy this avoids having to update this information later and keeping it in sync in a race-free fashion. Since this information has not been used that, this patch actually does not change anything, it just removes the declaration and initialization.
