parisc: provide macro to create exception table entries
Provide a macro ASM_EXCEPTIONTABLE_ENTRY() to create exception table entries and convert all open-coded places to use that macro. This patch is a first step toward creating a exception table which only holds 32bit pointers even on a 64bit kernel. That way in my own kernel I was able to reduce the in-kernel exception table from 44kB to 22kB. Signed-off-by: Helge Deller <deller@gmx.de>
