when compiling linux-mips with kmemtrace enabled, there will be an error: include/linux/trace_seq.h:12: error: 'PAGE_SIZE' undeclared here (not in a function) I checked the source code and found trace_seq.h used PAGE_SIZE but not included the relative header file, so, fix it via adding the header file <asm/page.h> Acked-by: Frederic Weisbecker <fweisbec@gmail.com> Acked-by: Pekka Enberg <penberg@cs.helsinki.fi> Signed-off-by: Wu Zhangjin <wuzj@lemote.com> LKML-Reference: <1244962350-28702-1-git-send-email-wuzhangjin@gmail.com> Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
