Add in the Linux IOCTL shim and create the megadev0 device so
Linux LSI MegaRaid tools can run on FreeBSD until Linux emulation. Add in the Linux IOCTL shim and create the megadev0 device so Linux LSI MegaRaid tools can run on FreeBSD until Linux emulation. Add glue to build the modules but don't tie it into the build yet until I test it from the CVS repo. via the mirror on an amd64 machine. Tie this into the Linux32 emulation on amd64 so the tools can run on amd64 kernel. Cleaned up by: ps (amr_linux.c)
