Subject[PATCH] tracing: fix undeclared 'PAGE_SIZE' in include/linux/trace_seq.h
Date
From: Wu Zhangjin <wuzj@lemote.com>

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>
