Commit 1343f776c51ecbed89eff5e174188523c731a8fe

Exists in master and in 4 other branches v3.2_AM335xPSP_04.06.00.11, v3.2_NEWT335xPSP_04.06.00.11, v3.2_SBC_SMARTMEN, v3.2_SMARCT335xPSP_04.06.00.11

[PATCH] m32r: NONCACHE_OFFSET in _port2addr 

Change _port2addr() not to add NONCACHE_OFFSET.  Adding NONCACHE_OFFSET
requires needless address adjusting by a driver using ioremap() like a
SMC91x driver.
