Andy Lutomirski d24df8ecf9 x86/fault: Skip the AMD erratum #91 workaround on unaffected CPUs 
According to the Revision Guide for AMD Athlon™ 64 and AMD Opteron™
Processors, only early revisions of family 0xF are affected. This will
avoid unnecessarily fetching instruction bytes before sending SIGSEGV to
user programs.
