Items for CHANGELOG.md in 4.14

[Paul Durrant <xadimgnik@xxxxxxxxx>]

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
