From ba15c86185e9017f03b31a0699a0c09d1dc0d41c Mon Sep 17 00:00:00 2001 From: Atish Patra Date: Fri, 22 Feb 2019 11:41:37 -0800 Subject: RISC-V: Remove NR_CPUs check during hartid search from DT In non-smp configuration, hartid can be higher that NR_CPUS. riscv_of_processor_hartid should not be compared to hartid to NR_CPUS in that case. Moreover, this function checks all the DT properties of a hart node. NR_CPUS comparison seems out of place.
