Subject: [PATCH] kmemtrace:fix undeclared 'PAGE_SIZE' via asm/page.h

From: Wu Zhangjin <wuzj@...ote.com>

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
