commit 537bddd069c743759addf422d0b8f028ff0f8dbc upstream.
The computation of TOHM is off by one bit. This missed bit results in
too low a value for TOHM, which can cause errors in regular memory to
incorrectly report:
EDAC MC0: 1 CE Error at MMIOH area, on addr 0x000000207fffa680 on any memory
Fixes: 50d1bb93672f ("sb_edac: add support for Haswell based systems")
