Subject: [PATCH 1/2] asm-generic/export.h: make __ksymtab_* local symbols

For EXPORT_SYMBOL from C files, <linux/export.h> defines __ksymtab_*
as local symbols.

For EXPORT_SYMBOL from assembly, in contrast, <asm-generic/export.h>
produces globally-visible __ksymtab_* symbols due to this .globl
directive.

I do not understand why this must be global.  It still works without
this .globl directive.
