  commit 25f5530fc43b9c5d63f840be5d7be8ed4d1ed92e
  Author: Andrew Cooper <andrew.cooper3@xxxxxxxxxx>
  Date:   Thu Nov 28 15:37:17 2019 +0100
  
      x86/vvmx: Fix livelock with XSA-304 fix
      
      It turns out that the XSA-304 / CVE-2018-12207 fix of disabling executable
      superpages doesn't work well with the nested p2m code.
      
      Nested virt is experimental and not security supported, but is useful for
      development purposes.  In order to not regress the status quo, disable the
      XSA-304 workaround until the nested p2m code can be improved.
      
      Introduce a per-domain exec_sp control and set it based on the current
      opt_ept_exec_sp setting.  Take the oppotunity to omit a PVH hardware 
domain
      from the performance hit, because it is already permitted to DoS the 
system in
      such ways as issuing a reboot.
      
      When nested virt is enabled on a domain, force it to using executable
      superpages and rebuild the p2m.
      
      Having the setting per-domain involves rearranging the internals of
      parse_ept_param_runtime() but it still retains the same overall semantics 
-
      for each applicable domain whose setting needs to change, rebuild the p2m.

  commit 25f5530fc43b9c5d63f840be5d7be8ed4d1ed92e
  Author: Andrew Cooper <andrew.cooper3@xxxxxxxxxx>
  Date:   Thu Nov 28 15:37:17 2019 +0100
  
      x86/vvmx: Fix livelock with XSA-304 fix
      
      It turns out that the XSA-304 / CVE-2018-12207 fix of disabling executable
      superpages doesn't work well with the nested p2m code.
      
      Nested virt is experimental and not security supported, but is useful for
      development purposes.  In order to not regress the status quo, disable the
      XSA-304 workaround until the nested p2m code can be improved.
      
      Introduce a per-domain exec_sp control and set it based on the current
      opt_ept_exec_sp setting.  Take the oppotunity to omit a PVH hardware 
domain
      from the performance hit, because it is already permitted to DoS the 
system in
      such ways as issuing a reboot.
      
      When nested virt is enabled on a domain, force it to using executable
      superpages and rebuild the p2m.
      
      Having the setting per-domain involves rearranging the internals of
      parse_ept_param_runtime() but it still retains the same overall semantics 
-
      for each applicable domain whose setting needs to change, rebuild the p2m.
