Subject: [PATCH] riscv: mm: use bitmap_zero() API
Date: Sat, 6 May 2023 17:11:41 +0800 (CST)	[thread overview]
Message-ID: <202305061711417142802@zte.com.cn> (raw)

From: Ye Xingchen <ye.xingchen@zte.com.cn>

bitmap_zero() is faster than bitmap_clear(), so use bitmap_zero()
instead of bitmap_clear().
