Julian Calaby - Jan. 6, 2009, 2:58 p.m.
From: Sam Ravnborg <sam@ravnborg.org>

sparc: Create a new file lib/ksyms.c and add export of all symbols
defined in assembler in lib/ to this file.

Remove the duplicate entries from kernel/sparc_ksyms_*.c

The rationale behind this is that the EXPORT_SYMBOL() should be close to
their definition and we cannot add designate a symbol to be exported in
assembler so at least put it in a file in the same directory.
