[PATCH 2/3] KVM: arm64: Shuffle KVM_HOST_DATA_FLAG_* indices

From: Mark Rutland <mark.rutland@arm.com>
Date: 2026-01-06 17:37:34
Also in: kvmarm
Subsystem: arm64 port (aarch64 architecture), kernel virtual machine for arm64 (kvm/arm64), the rest · Maintainers: Catalin Marinas, Will Deacon, Marc Zyngier, Oliver Upton, Linus Torvalds

There's a gap in the KVM_HOST_DATA_FLAG_* indices since the removal of
KVM_HOST_DATA_FLAG_HOST_SVE_ENABLED and
KVM_HOST_DATA_FLAG_HOST_SME_ENABLED in commits:

* 459f059be702 ("KVM: arm64: Remove VHE host restore of CPACR_EL1.ZEN")
* 407a99c4654e ("KVM: arm64: Remove VHE host restore of CPACR_EL1.SMEN")

Shuffle the indices to remove the gap, as Oliver requested at the time of
the removals:

  https://lore.kernel.org/linux-arm-kernel/Z6qC4qn47ONfDCSH@linux.dev/ (local)

There should be no functional change as a result of this patch.
