The following commit:
ddb5cdbafaaa ("kbuild: generate KSYMTAB entries by modpost")
deprecated <asm/export.h>, which is now a wrapper of <linux/export.h>.
Use <linux/export.h> in *.S as well as in *.c files.
After all the <asm/export.h> lines are replaced, <asm/export.h> and
<asm-generic/export.h> will be removed.
