Subject: [PATCH -next v6 05/10] arm64: extable: move _cond_extable to _cond_uaccess_extable
Date: Tue, 21 Jun 2022 07:26:33 +0000	[thread overview]
Message-ID: <20220621072638.1273594-6-tongtiangen@huawei.com> (raw)
In-Reply-To: <20220621072638.1273594-1-tongtiangen@huawei.com>

Currently, We use _cond_extable for cache maintenance uaccess helper
caches_clean_inval_user_pou(), so this should be moved over to
EX_TYPE_UACCESS_ERR_ZERO and rename _cond_extable to _cond_uaccess_extable
for clarity.
