Alexey Brodkin 4b32e89af7 ARC: mm: fix building for MMU v2 ... ARC700 cores with MMU v2 don't have IC_PTAG AUX register and so we only define ARC_REG_IC_PTAG for MMU versions >= 3. But current implementation of cache_line_loop_vX() routines assumes availability of all of them (v2, v3 and v4) simultaneously. And given undefined ARC_REG_IC_PTAG if CONFIG_MMU_VER=2 we're seeing compilation problem: ---------------------------------->8------------------------------- CC arch/arc/mm/cache.o arch/arc/mm/cache.c: In function '__cache_line_loop_v3': arch/arc/mm/cache.c:270:13: error: 'ARC_REG_IC_PTAG' undeclared (first use in this function) aux_tag = ARC_REG_IC_PTAG; ^ arch/arc/mm/cache.c:270:13: note: each undeclared identifier is reported only once for each function it appears in scripts/Makefile.build:258: recipe for target 'arch/arc/mm/cache.o' failed ---------------------------------->8------------------------------- The simples fix is to have ARC_REG_IC_PTAG defined regardless MMU version being used. We don't use it in cache_line_loop_v2() anyways so who cares. Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com> Signed-off-by: Vineet Gupta <vgupta@synopsys.com>		2015-12-21 12:10:40 +05:30
