Geert Uytterhoeven e47e005598 sh: landisk: Add missing initialization of sh_io_port_base ... [ Upstream commit 0c64a0dce5 ] The Landisk setup code maps the CF IDE area using ioremap_prot(), and passes the resulting virtual addresses to the pata_platform driver, disguising them as I/O port addresses. Hence the pata_platform driver translates them again using ioport_map(). As CONFIG_GENERIC_IOMAP=n, and CONFIG_HAS_IOPORT_MAP=y, the SuperH-specific mapping code in arch/sh/kernel/ioport.c translates I/O port addresses to virtual addresses by adding sh_io_port_base, which defaults to -1, thus breaking the assumption of an identity mapping. Fix this by setting sh_io_port_base to zero. Fixes: 37b7a97884 ("sh: machvec IO death.")
