That sentence reads funny.

Will rewrite this sentence to make it more understandable. :)

In general, you seem to be explaining *what* your patches do and not
*why*. This is the wrong. Always explain the *why* - the *what* is
visible from the diff.

You probably need to brush up on
Documentation/process/submitting-patches.rst, section 2.

All right, will relearn the document and rework the patch descriptions.

+	case 0x18:
+		if (boot_cpu_data.x86_vendor == X86_VENDOR_HYGON) {
+			pr_cont("Fam18h ");

Didn't we agree that you'll verify whether family 0x18 is going to be
Hygon only?

What happened to that checking?
...
Same here.

What's up?

Will remove all the remaining unneeded Hygon vendor checking through
the whole patch set to minimize the code modification.

Thanks,
Pu Wen
