Hi Andrew, After merging the akpm tree, today's linux-next build (sparc64 defconfig) failed like this:
arch/sparc/kernel/process_64.c: In function 'arch_trigger_all_cpu_backtrace':
arch/sparc/kernel/process_64.c:267:3: error: ISO C90 forbids mixed declarations
and code [-Werror=declaration-after-statement]
cc1: all warnings being treated as errors
Caused by commit dd0063a16aa1 ("nmi: provide the option to issue an NMI
back trace to every cpu but current").
I have no idea why I did not see this yesterday.
I applied the following fix up patch:
