qemu-kvm/0006-Machine-type-related-general-changes.patch
Danilo C. L. de Paula b190fee134 Update qemu-kvm with 4.1.0 patches 
Since qemu-kvm tree is syncronized with 4.1.0 now, it's
easier to handle this as 4.1.0 and not as rc4

Subject: Machine type related general changes
This patch is first part of original "Add RHEL machine types" patch we
split to allow easier review. It contains changes not related to any
architecture.
Signed-off-by: Miroslav Rezanina <mrezanin@redhat.com>
Rebase changes (4.0.0):
- Remove e1000 device duplication changes to reflect upstream solution
- Rewrite machine compat properties to upstream solution
Rebase changes (4.1.0-rc0):
- Removed optional flag for machine compat properties (upstream)
Rebase changes (4.1.0-rc1):
- Remove c3e002cb chunk from hw/net/e1000.c
Rebase changes (4.1.0-rc2):
- Reorder compat structures
- Use one format for compat scructures
Rebase changes (4.1.0-rc4):
- Added compat for virtio-balloon-pci.any_layout for rhel71
Merged patches (4.0.0):
- d4c0957 compat: Generic HW_COMPAT_RHEL7_6
- cbac773 virtio: Make disable-legacy/disable-modern compat properties optional
Merged patches (4.0.0-rc0):
- 479ad30 redhat: fix cut'n'paste garbage in hw_compat comments
- f19738e compat: Generic hw_compat_rhel_8_0
