You may want to configure git on your end to emit an explicit 'From: Justin Terry (VM) ' in the body of each message you send, to override the mailman overwrite of your messages to the list. I don't know whether 'git config format.from "Your Name "' is sufficient for this (the help for git format-patch mentions that it adds the From: line to the body only when it differs textually from the From: header, but doesn't mention a way to force the From: line in the body) even when the two start out the same. > Implements the CPUID trap for CPUID 1 to include the > CPUID_EXT_HYPERVISOR flag in the ECX results.
