powerpc/8xx: Fix do_mtspr_cpu6() build on older compilers
GCC < 4.9 is unable to build this, saying: arch/powerpc/mm/8xx_mmu.c:139:2: error: memory input 1 is not directly addressable Change the one-element array into a simple variable to avoid this. Fixes: 1458dd951f7c ("powerpc/8xx: Handle CPU6 ERRATA directly in mtspr() macro") Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr> Cc: Scott Wood <oss@buserror.net> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
