parisc: Fix HPMC handler by increasing size to multiple of 16 bytes
Make sure that the HPMC (High Priority Machine Check) handler is 16-byte aligned and that it's length in the IVT is a multiple of 16 bytes. Otherwise PDC may decide not to call the HPMC crash handler. Signed-off-by: Helge Deller <deller@gmx.de> Cc: stable@vger.kernel.org
