[PATCH 7/8] next: sh: Fix compile error
From: Guenter Roeck
Commit a91ed664749c ("kernel: tighten rules for ACCESS ONCE") results in a
compile failure for sh builds with CONFIG_X2TLB enabled.
arch/sh/mm/gup.c: In function 'gup_get_pte':
arch/sh/mm/gup.c:20:2: error: invalid initializer
make[1]: *** [arch/sh/mm/gup.o] Error 1
Replace ACCESS_ONCE with READ_ONCE to fix the problem.
