Scalable MCA systems have various types of banks. The bank's type can
determine how we handle errors from it. For example, if a bank represents
a UMC then we will need to convert its address from a normalized address
to a system physical address before handling the error.
Define a static function to return a bank's SMCA type.

check if the ErrorCodeExt value is 0x0 or 0x8 in mce_is_memory_error(), but
we don't check the bank. This means that we could flag non-memory errors as

We know that we want to flag DRAM ECC errors as memory errors, so let's do
those cases first. We can add more cases later when needed.
Check that bank type is UMC and xec is 0 on SMCA systems.
Check that bank is 4 (Northbridge) and xec is 8 on legacy systems.
Define a wrapper function in mce_amd.c so we can use SMCA enums.

^^^^^^^^
That's a NULL ptr deref waiting to happen.
Also, struct smca_bank bank should be a pointer.
I ended up committing this:

You don't need brackets around the return statements.

x86/MCE: Report only DRAM ECC as memory errors on AMD systems
The MCA_STATUS[ErrorCodeExt] field is very bank type specific.
We currently check if the ErrorCodeExt value is 0x0 or 0x8 in
mce_is_memory_error(), but we don't check the bank number. This means
that we could flag non-memory errors as memory errors.
We know that we want to flag DRAM ECC errors as memory errors, so let's do
those cases first. We can add more cases later when needed.
Define a wrapper function in mce_amd.c so we can use SMCA enums.
