Subject: [PATCH v4 11/11] x86: select ARCH_SUPPORTS_PT_RECLAIM if X86_64
Date: Wed, 4 Dec 2024 19:09:51 +0800 [thread overview]
Message-ID: <841c1f35478d5354872d307888979c9e20de9c09.1733305182.git.zhengqi.arch@bytedance.com> (raw)
In-Reply-To: <cover.1733305182.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.
