Since we're already discussing this today, I noticed the list rewrites
your headers due to SPF policies at microsoft.com, to the point that a
blind 'git am' on the list message will attempt to attribute your patch
to 'Justin Terry (VM) via Qemu-devel <address@hidden>' if the
maintainer is not careful.
You may want to configure git on your end to emit an explicit 'From:
Justin Terry (VM) <address@hidden>' 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
<address@hidden>"' 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. This was preventing some
older linux kernels from booting when trying to access MSR's that dont
s/dont/don't/
make sense when virtualized.
