Hi Andrew,
After merging the akpm tree, today's linux-next build (powerpc ppc44x_defconfig) failed like this:
kernel/printk/printk.c: In function 'log_buf_add_cpu': kernel/printk/printk.c:269:37: error: 'CONFIG_LOG_CPU_MAX_BUF_SHIFT' undeclared (first use in this function) #define __LOG_CPU_MAX_BUF_LEN (1 << CONFIG_LOG_CPU_MAX_BUF_SHIFT) ^ kernel/printk/printk.c:864:42: note: in expansion of macro '__LOG_CPU_MAX_BUF_LEN' cpu_extra = (num_possible_cpus() - 1) * __LOG_CPU_MAX_BUF_LEN; ^ kernel/printk/printk.c:269:37: note: each undeclared identifier is reported only once for each function it appears in #define __LOG_CPU_MAX_BUF_LEN (1 << CONFIG_LOG_CPU_MAX_BUF_SHIFT) ^ kernel/printk/printk.c:864:42: note: in expansion of macro '__LOG_CPU_MAX_BUF_LEN' cpu_extra = (num_possible_cpus() - 1) * __LOG_CPU_MAX_BUF_LEN; ^
Caused by commit 58209adf633e ("printk: allow increasing the ring buffer depending on the number of CPUs"). CONFIG_LOG_CPU_MAX_BUF_SHIFT is not defined for this configuration.
