Items for CHANGELOG.md in 4.14

Items for CHANGELOG.md in 4.14

[Paul Durrant]

All,

  In the last community call I took an ACTION to send a reminder email to submit patches to get CHANGELOG.md up to date. Several
items were mentioned during the call (see minutes at https://cryptpad.fr/pad/#/2/pad/edit/qPQUEQEv3nJJ97clS8b2KdtP/):

- Ability to conditionally compile-out 32-bit PV guests (security attack surface reduction)
- Basic support for AMD Milan CPUS
- Golang binding advances
- x2apic, improvements on tlbflush hypercall
- General improvements in pvshim
- Xen on Hyper-V
- VM-fork

  Roger has already sent a patch for the x2apic/tlbflush improvements (which has not yet been committed). Can those with the
relevant information regarding the other items please send patches a.s.a.p.?

  Thanks,

    Paul Durrant

As part of this work, there is now a "framework" to make it easy to port
Xen to run on top of hypervisors. Does this need calling out?

IMO it is worth calling out this; it encourages further development not strictly related to Hyper-V.
