Subject: [PATCH 1/4] mm: percpu: Generalize percpu related config
Date: Thu, 16 Dec 2021 19:23:56 +0800 [thread overview]
Message-ID: <20211216112359.103822-2-wangkefeng.wang@huawei.com> (raw)
In-Reply-To: <20211216112359.103822-1-wangkefeng.wang@huawei.com>
The HAVE_SETUP_PER_CPU_AREA/NEED_PER_CPU_EMBED_FIRST_CHUNK/
NEED_PER_CPU_PAGE_FIRST_CHUNK/USE_PERCPU_NUMA_NODE_ID configs,
which have duplicate definitions on platforms that subscribe it.
Move them into mm, drop these redundant definitions and instead
just select it on applicable platforms.

Date: Thu, 16 Dec 2021 19:23:56 +0800 [thread overview]
Message-ID: <20211216112359.103822-2-wangkefeng.wang@huawei.com> (raw)
In-Reply-To: <20211216112359.103822-1-wangkefeng.wang@huawei.com>
The HAVE_SETUP_PER_CPU_AREA/NEED_PER_CPU_EMBED_FIRST_CHUNK/
NEED_PER_CPU_PAGE_FIRST_CHUNK/USE_PERCPU_NUMA_NODE_ID configs,
which have duplicate definitions on platforms that subscribe it.
Move them into mm, drop these redundant definitions and instead
just select it on applicable platforms.

Subject: [PATCH 1/4] mm: percpu: Generalize percpu related config
Date: Thu, 16 Dec 2021 11:23:56 +0000 [thread overview]
Message-ID: <20211216112359.103822-2-wangkefeng.wang@huawei.com> (raw)
In-Reply-To: <20211216112359.103822-1-wangkefeng.wang@huawei.com>
The HAVE_SETUP_PER_CPU_AREA/NEED_PER_CPU_EMBED_FIRST_CHUNK/
NEED_PER_CPU_PAGE_FIRST_CHUNK/USE_PERCPU_NUMA_NODE_ID configs,
which have duplicate definitions on platforms that subscribe it.
Move them into mm, drop these redundant definitions and instead
just select it on applicable platforms.
