Thank you. I think we ought to demand a product recall for everything Intel.

Alberto,
Despite the disinformation Intel initially spread, it looks like AMD processors
are not vulnerable to Meltdown (which these patches should address).
Spectre is a different thing altogether, and affects AMD and Intel as well, but
these are other CVEs.
Stijn
AFAIK AMD processors that don't need that are from Zen onwards. Older
ones are impacted.

It looks like PCID and INVPCID support is likely to be back ported to

Hi all,
I am a moron, I missed:
+skip:
+ if (boot_cpu_data.x86_vendor == X86_VENDOR_AMD)
+ goto disable;
It uses a different path...

Hi Kevin,
I am not following :-) For AMD, there should not be a tradeoff as
there is no need for the page table isolation.

I’ll let an adult decide the performance/security tradeoff.

Hi,
Where in 4.9.75 does it avoid the page table isolation mitigation for AMD?
Committed to the 4.14 and 4.15 branch is:

Agreed. So this will seemingly regress something like an APU2 and
therefore probably should not be merged to LEDE as-is?
