Subject: [RFC PATCH v2 7/7] x86: select ARCH_SUPPORTS_PT_RECLAIM if X86_64
Date: Mon, 5 Aug 2024 20:55:11 +0800 [thread overview]
Message-ID: <0949a17afe11cf108b8a09a538c00c93cdc5507e.1722861064.git.zhengqi.arch@bytedance.com> (raw)
In-Reply-To: <cover.1722861064.git.zhengqi.arch@bytedance.com>
Now, x86 has fully supported the CONFIG_PT_RECLAIM feature, and
reclaiming PTE pages is profitable only on 64-bit systems, so select
ARCH_SUPPORTS_PT_RECLAIM if X86_64.
