[PATCH 0/7] qemu: Fix broken qemu caps cache invalidation

[Peter Krempa]

Bugs in the code meant to invalidate the qemu capabilities cache
resulted in us always re-probing capabilities on startup of
libvirtd/virtqemud. This got extremely annoying with the modern
deployments using --timeout.

Apart from issues in inserting the detected features, it also turns out
that AMD boxes report data which changes based on which CPU the
instruction happened to execute, so we need to mask that out.

Peter Krempa (7):
  virCPUx86DataIsIdentical: Add debug output
  virCPUx86DataGetHost: Fix construction of the returned data
  virHostCPUGetCPUID: Add comment on how KVM_GET_SUPPORTED_CPUID works
  util: virhostcpu: Extract filtering of the returned data from
    virHostCPUGetCPUID
  virHostCPUGetCPUID: Fix possible allocation of huge amount of memory
  virHostCPUGetCPUID: Limit the buffer size ranges
  virHostCPUGetCPUIDFilterVolatile: Filter out topology data on AMD
