Subject: [PATCH v3 9/9] x86: select ARCH_SUPPORTS_PT_RECLAIM if X86_64
Date: Thu, 14 Nov 2024 15:00:00 +0800 [thread overview]
Message-ID: <69c25b17661499afe4b35f1d30b26dd346a649ec.1731566457.git.zhengqi.arch@bytedance.com> (raw)
In-Reply-To: <cover.1731566457.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.
