parisc: Handle R_PARISC_PCREL32 relocations in kernel modules
Commit 0de7985 (parisc: Use generic extable search and sort routines) changed the exception tables to use 32bit relative offsets. This patch now adds support to the kernel module loader to handle such R_PARISC_PCREL32 relocations for 32- and 64-bit modules. Signed-off-by: Helge Deller <deller@gmx.de>
