[Qemu-devel] [PATCH 00/15] QEMU KVM_GET_SUPPORTED_CPUID cleanups and fixes

[Eduardo Habkost]

Most of this series are just cleanups that will help when making -cpu
check/enforce work properly, with some fixes.

In addition to code movements, the main changes are:
 - x2apic won't be enabled if in-kernel irqchip is disabled
   (patch 10)
 - CPUID feature bit filtering is done much earlier, and inside 
target-i386/cpu.c
   (patch 13)
 - CPUID leaf 7 feature bits are now filterd based on GET_SUPPORTED_CPUID too
   (patch 15)

Eduardo Habkost (15):
  i386: kvm: kvm_arch_get_supported_cpuid: move R_EDX hack outside of
    for loop
  i386: kvm: kvm_arch_get_supported_cpuid: clean up has_kvm_features
    check
  i386: kvm: kvm_arch_get_supported_cpuid: use 'entry' variable
  i386: kvm: extract register switch to cpuid_entry_get_reg() function
  i386: kvm: extract CPUID entry lookup to cpuid_find_entry() function
  i386: kvm: extract try_get_cpuid() loop to get_supported_cpuid()
    function
  i386: kvm: kvm_arch_get_supported_cpuid: replace if+switch with
    single 'if'
  i386: kvm: set CPUID_EXT_HYPERVISOR on kvm_arch_get_supported_cpuid()
  i386: kvm: set CPUID_EXT_TSC_DEADLINE_TIMER on
    kvm_arch_get_supported_cpuid()
  i386: kvm: x2apic is not supported without in-kernel irqchip
  i386: kvm: mask cpuid_kvm_features earlier
  i386: kvm: mask cpuid_ext4_features bits earlier
  i386: kvm: filter CPUID feature words earlier, on cpu.c
  i386: kvm: reformat filter_features_for_kvm() code
  i386: kvm: filter CPUID leaf 7 based on GET_SUPPORTED_CPUID, too
