EDAC, amd64_edac: Shift wrapping issue in f1x_get_norm_dct_addr()
commit 6f3508f61c814ee852c199988a62bd954c50dfc1 upstream.
dct_sel_base_off is declared as a u64 but we're only using the lower 32
bits because of a shift wrapping bug. This can possibly truncate the
upper 16 bits of DctSelBaseOffset[47:26], causing us to misdecode the CS
row.
Fixes: c8e518d5673d ('amd64_edac: Sanitize f10_get_base_addr_offset')
