[PATCH v3 0/4] Updates for ARC, LMBench

Hi, There'a cosmetic fix for ARC to show the -mcpu in config. And there's a bunch of histtoric patches in out github repo to get LMBench running. Changes since v2 - Added another LMBench fix (to lat_rpc) - Added -mcpu for all ARC CPUs as suggested by Peter Thx, -Vineet Vineet Gupta (4):

[PATCH v6 2/3] risc-v: Use generic io.h helpers for nommu

From: Niklas Schnelle Without MMU support PCI_IOBASE is left undefined because PCI_IO_END is VMEMMAP_START. Nevertheless the in*()/out*() helper macros are left defined with uses of PCI_IOBASE. At the moment this only compiles because asm-generic/io.h defines PCI_IOBASE as 0 if it is undefined

[PATCH v6 3/3] asm-generic/io.h: warn in inb() and friends with undefined PCI_IOBASE

When PCI_IOBASE is not defined, it is set to 0 such that it is ignored in calls to the readX/writeX primitives. This triggers clang's -Wnull-pointer-arithmetic warning and will result in illegal accesses on platforms that do not support I/O ports. Make things explicit and silence the warning by
