x86: SGI UV: Map MMIO-High memory range UV depends on the MMRHI space being identity mapped. The patch: x86: Make 64-bit efi_ioremap use ioremap on MMIO regions changed this to make efi regions at a different address using ioremap. Add the identity mapping to uv_system_init. ( Note this code was previously present but was deleted when BIOS added the ranges to the EFI map - previous efi code identify mapped the ranges. ) Signed-off-by: Jack Steiner <steiner@sgi.com> LKML-Reference: <20090909154339.GA7946@sgi.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
