agreed there. The main reason for me doing this was to provide a "generic" mechanism that mimic how we boot kernels on PPC. The other issue w/providing this on all arch's is that the number of params passed via regs may vary and I don't know what is for arm, avr32, blackfin, i386, m68k, microblaze, mips, nios, nios2, and sh. and each variation will require a different prototype. if someone can tell me what the number of args are for each arch we can see about providing this everywhere. - k ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
