[PATCH] PA-RISC updates

PA-RISC updates for 2.6.0-test6
 - Some more support for 64-bit userspace
 - Move many EXPORT_SYMBOLs out of parisc_ksyms.c
 - Make both the OSS and ALSA harmony drivers build
 - ioctl typechecking
 - Make math-emu build without warnings.
 - Persuade SuckyIO to not crash the machine.
