Subject: [RFC PATCH 7/7] x86: select ARCH_SUPPORTS_PT_RECLAIM if X86_64
Date: Mon, 1 Jul 2024 16:46:48 +0800 [thread overview]
Message-ID: <0f3aacc9707da962398de71c127e7771c6798062.1719570849.git.zhengqi.arch@bytedance.com> (raw)
In-Reply-To: <cover.1719570849.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.
