[Qemu-devel] [PATCH v4 01/14] linux-headers: update linux headers to kvm-ppc-next-5.2-1

[Cédric Le Goater]

This updates the kvm headers to commit 0caecf5b0019 (kvm-ppc-next-5.2-1)
in branch kvm-ppc-next from :

  https://git.kernel.org/pub/scm/linux/kernel/git/paulus/powerpc.git/

These changes provide the interface with the KVM device implementing
the XIVE native exploitation interrupt mode.

Signed-off-by: Cédric Le Goater <address@hidden>

 The XIVE capability number will conflict with kvm-arm :
 
 555f3d03e7fb ("KVM: arm64: Add a capability to advertise SVE support")
 a243c16d18be ("KVM: arm64: Add capability to advertise ptrauth for guest")
