powerpc/cacheinfo: Use cpumap_print to print cpumap
Tejun Heo had modified shared_cpu_map_show() to use scnprintf instead of cpumap_print during support for *pb[l] format. Refer commit 0c118b7bd09a ("powerpc: use %*pb[l] to print bitmaps including cpumasks and nodemasks"). cpumap_print_to_pagebuf() is a standard function to print cpumap. With commit 9cf79d115f0d ("bitmap: remove explicit newline handling using scnprintf format string"), there is no need to print explicit newline and trailing null character. cpumap_print_to_pagebuf() internally uses scnprintf(). Hence replace scnprintf() with cpumap_print_to_pagebuf(). Note: shared_cpu_map_show() in drivers/base/cacheinfo.c already uses cpumap_print_to_pagebuf(). Before this patch: # cat /sys/devices/system/cpu0/cache/index1/shared_cpu_map 00ff # (Notice the extra blank line).
