Subject: [RFC PATCH v2 3/3] arm64: tlb: add support for TTL in some functions
Date: Thu, 12 Mar 2020 12:10:18 +0800	[thread overview]
Message-ID: <20200312041018.1927-4-yezhenyu2@huawei.com> (raw)
In-Reply-To: <20200312041018.1927-1-yezhenyu2@huawei.com>

Add support for TTL in some ARM64-Architecture functions. The
relevant functions are:

	__pte_free_tlb
	__pmd_free_tlb
	__pud_free_tlb
	clear_flush
	get_clear_flush
