Subject: arm64: page: use asm EXPORT_SYMBOL()
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=50fdecb292e0b2d98b0b2bf319a4faa1aa7d666f;p=openwrt%2Fstaging%2Fblogic.git

arm64: page: use asm EXPORT_SYMBOL()

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.
