Subject: [v3 PATCH 3/8] RISC-V: Remove NR_CPUs check during hartid search from DT
Date:   Thu,  7 Feb 2019 17:51:16 -0800
Message-Id: <1549590681-24125-4-git-send-email-atish.patra@wdc.com>
In-Reply-To: <1549590681-24125-1-git-send-email-atish.patra@wdc.com>
References: <1549590681-24125-1-git-send-email-atish.patra@wdc.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

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.
