Subject: [PATCH V4 12/23] RISC-V: cpufeature: Avoid calling riscv_of_processor_hartid()
Date: Tue,  4 Apr 2023 23:50:26 +0530	[thread overview]
Message-ID: <20230404182037.863533-13-sunilvl@ventanamicro.com> (raw)
In-Reply-To: <20230404182037.863533-1-sunilvl@ventanamicro.com>

riscv_fill_hwcap() finds hartid of each cpu but never really uses
it. So, remove this unnecessary call.
