While doing the backports of the recently committed XSA-59 workaround patches, when reaching 4.2 I had to inspect the fuzzy applies resulting from the x86-64 conditionals in that code, making me realize that what we're doing is still insufficient: We wrongly assume to be able to access extended config registers (i.e. MMCFG space) at boot time. Fixing that, in turn made me again look at the one workaround that was in place in the same function before that recent series, just to find that the list very likely should have been extended quite a while back. 1: apply quirks at device setup time rather than only at boot 2: extend error report masking workaround to newer chipsets This (still) is CVE-2013-3495 / XSA-59.
