[PATCH v2 03/13] KVM: arm64: Fix names of config register fields
From: Fuad Tabba <hidden>
Date: 2021-06-15 14:21:12
Also in:
kvm, 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
Change the names of hcr_el2 register fields to match the Arm Architecture Reference Manual. Easier for cross-referencing and for grepping. Also, change the name of CPTR_EL2_RES1 to CPTR_NVHE_EL2_RES1, because res1 bits are different for VHE. No functional change intended.
