FreeBSD/mips port. The FreeBSD/mips port targets mips32, mips64, mips32r2 and mips64r2 (and close relatives) processors. There presently is support for ADMtek ADM5120, A mips 4Kc in a malta board, the RB533 routerboard (based on IDT RC32434) and some preliminary support for sibtye/broadcom designs. Other hardware support will be forthcomcing. This port boots multiuser under gxemul emulating the malta board and also bootstraps on the hardware whose support is forthcoming... Oleksandr Tymoshenko, Wojciech Koszek, Warner Losh, Olivier Houchard, Randall Stewert and others that have contributed to the mips2 and/or mips2-jnpr perforce branches. Juniper contirbuted a generic mips port late in the life cycle of the misp2 branch. Warner Losh merged the mips2 and Juniper code bases, and others list above have worked for the past several months to get to multiuser. In addition, the mips2 work owe a debt to the trail blazing efforts of the original mips branch in perforce done by Juli Mallett.

o) Add COMPAT_FREEBSD32 support for MIPS kernels using the n64 ABI with userlands using the o32 ABI. This mostly follows nwhitehorn's lead in implementing COMPAT_FREEBSD32 on powerpc64. o) Add a new type to the freebsd32 compat layer, time32_t, which is time_t in the 32-bit ABI being used. Since the MIPS port is relatively-new, even the 32-bit ABIs use a 64-bit time_t. o) Because time{spec,val}32 has the same size and layout as time{spec,val} on MIPS with 32-bit compatibility, then, disable some code which assumes otherwise wrongly when built for MIPS. A more general macro to check in this case would seem like a good idea eventually. If someone adds support for using n32 userland with n64 kernels on MIPS, then they will have to add a variety of flags related to each piece of the ABI that can vary. That's probably the right time to generalize further. o) Add MIPS to the list of architectures which use PAD64_REQUIRED in the freebsd32 compat code. Probably this should be generalized at some point. Reviewed by: gonzo
