Subject: [PATCHv2 06/10] arm64: page: use asm EXPORT_SYMBOL()
Date: Fri,  7 Dec 2018 18:08:19 +0000	[thread overview]
Message-ID: <20181207180823.36612-7-mark.rutland@arm.com> (raw)
In-Reply-To: <20181207180823.36612-1-mark.rutland@arm.com>

For a while now it's been possible to use EXPORT_SYMBOL() in assembly
files, which allows us to place exports immediately after assembly
functions, as we do for C functions.

As a step towards removing arm64ksyms.c, let's move the copy_page and
clear_page exports to the assembly files the functions are defined in.

There should be no functional change as a result of this patch.
