------------------

From: Al Viro <viro@xxxxxxxxxxxxxxxxxx>

[ Upstream commit c57e5dccb06decf3cb6c272ab138c033727149b5 ]

__cmpxchg_u8() had been added (initially) for the sake of
drivers/phy/ti/phy-tusb1210.c; the thing is, that drivers is
modular, so we need an export

Fixes: b344d6a83d01 "parisc: add support for cmpxchg on u8 pointers"
