x86/platform: Remove incorrect error message in x86_default_fixup_cpu_id()

Browse source

It's only called from amd.c:srat_detect_node(). The introduced
condition for calling the fixup code is true for all AMD
multi-node processors, e.g. Magny-Cours and Interlagos. There we
have 2 NUMA nodes on one socket. Thus there are cores having
different numa-node-id but with equal phys_proc_id.

There is no point to print error messages in such a situation.

The confusing/misleading error message was introduced with
commit 64be4c1c24 ("x86: Add
x86_init platform override to fix up NUMA core numbering").

Remove the default fixup function (especially the error message)
and replace it by a NULL pointer check, move the
Numascale-specific condition for calling the fixup into the
fixup-function itself and slightly adapt the comment.
