From 82f2202ddc97490994fad0dbfec04a014fa5163d Mon Sep 17 00:00:00 2001 From: "Wesley W. Terpstra" Date: Tue, 12 May 2020 10:26:36 -0700 Subject: irqchip/sifive-plic: Remove incorrect requirement about number of irq contexts A PLIC may not be connected to all the cores. In that case, nr_contexts may be less than num_possible_cpus. This requirement is only valid a single PLIC is the only interrupt controller for the whole system.
