Hi Steven, After merging the final tree, today's linux-next build (powerpc allyesconfig) failed like this: arch/powerpc/platforms/pseries/hvCall_inst.c: In function 'hcall_inst_init': arch/powerpc/platforms/pseries/hvCall_inst.c:143: warning: passing argument 1 of 'register_trace_hcall_entry' from incompatible pointer type arch/powerpc/include/asm/trace.h:100: note: expected 'void (*)(void *, long unsigned int, long unsigned int *)' but argument is of type 'void (*)(long unsigned int, long unsigned int *)' arch/powerpc/platforms/pseries/hvCall_inst.c:143: error: too few arguments to function 'register_trace_hcall_entry' arch/powerpc/platforms/pseries/hvCall_inst.c:146: warning: passing argument 1 of 'register_trace_hcall_exit' from incompatible pointer type arch/powerpc/include/asm/trace.h:122: note: expected 'void (*)(void *, long unsigned int, long unsigned int, long unsigned int *)' but argument is of type 'void (*)(long unsigned int, long unsigned int, long unsigned int *)' arch/powerpc/platforms/pseries/hvCall_inst.c:146: error: too few arguments to function 'register_trace_hcall_exit' arch/powerpc/platforms/pseries/hvCall_inst.c:147: warning: passing argument 1 of 'unregister_trace_hcall_entry' from incompatible pointer type arch/powerpc/include/asm/trace.h:100: note: expected 'void (*)(void *, long unsigned int, long unsigned int *)' but argument is of type 'void (*)(long unsigned int, long unsigned int *)' arch/powerpc/platforms/pseries/hvCall_inst.c:147: error: too few arguments to function 'unregister_trace_hcall_entry' Probably caused by commit 38516ab59fbc5b3bb278cf5e1fe2867c70cff32e ("tracing: Let tracepoints have data passed to tracepoint callbacks"). I applied this patch which builds (but may be incorrect). From: Stephen Rothwell <sfr@xxxxxxxxxxxxxxxx> Date: Fri, 28 May 2010 15:05:00 +1000 Subject: [PATCH] tracing: fix for tracepoint API change Commit 38516ab59fbc5b3bb278cf5e1fe2867c70cff32e "tracing: Let tracepoints have data passed to tracepoint callbacks" requires this fixup to the powerpc code.
