From: Wu Zhangjin <wuzj@xxxxxxxxxx> when compiling linux-mips with kmemtrace enabled, this error will be there: 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 include the relative header file, so, fix it via adding the header file <asm/page.h> this error will not be triggered in linux-x86 for there is a <asm/page.h> header file included in a certain header file. but which not means <asm/page.h> is not needed in trace_seq.h Signed-off-by: Wu Zhangjin <wuzj@xxxxxxxxxx> --- include/linux/trace_seq.h | 2 ++ 1 files changed, 2 insertions(+), 0 deletions(-) diff --git a/include/linux/trace_seq.h b/include/linux/trace_seq.h index c68bccb..c134dd1 100644 --- a/include/linux/trace_seq.h +++ b/include/linux/trace_seq.h @@ -3,6 +3,8 @@ #include <linux/fs.h> +#include <asm/page.h> + /* * Trace sequences are used to allow a function to call several other functions * to create a string of data to use (up to a max of PAGE_SIZE. -- 1.6.0.4
