[PATCH v5 0/6] target/i386: Restrict system-specific features from user emulation

["Philippe Mathieu-Daudé" <philmd@linaro.org>]

Since v4:
- Addressed Paolo's suggestions (clearly better)

Too many system-specific code (and in particular KVM related)
is pulled in user-only build. This led to adding unjustified
stubs as kludge to unagressive linker non-optimizations.

This series restrict x86 system-specific features to sysemu,
so we don't require any stub, and remove all x86 KVM declarations
from user emulation code (to trigger compile failure instead of
link one).

Philippe Mathieu-Daudé (6):
  target/i386: Check kvm_hyperv_expand_features() return value
  target/i386: Drop accel_uses_host_cpuid before
    x86_cpu_get_supported_cpuid
  target/i386: Call accel-agnostic x86_cpu_get_supported_cpuid()
  target/i386: Move x86_cpu_get_migratable_flags() around
  RFC target/i386: Restrict system-specific code from user emulation
  target/i386: Prohibit target specific KVM prototypes on user emulation
