[PATCH v5.5 14/30] KVM: Stop passing kvm_userspace_memory_region to arch memslot hooks
From: Sean Christopherson <seanjc@google.com>
Date: 2021-11-04 00:28:36
Also in:
kvm, kvm-riscv, kvmarm, linux-arm-kernel, linux-riscv, lkml
Subsystem:
arm64 port (aarch64 architecture), kernel virtual machine (kvm), kernel virtual machine for arm64 (kvm/arm64), kernel virtual machine for mips (kvm/mips), kernel virtual machine for powerpc (kvm/powerpc), kernel virtual machine for risc-v (kvm/riscv), kernel virtual machine for x86 (kvm/x86), kernel virtual machine for s390 (kvm/s390), linux for powerpc (32-bit and 64-bit), mips, risc-v architecture, s390 architecture, the rest, x86 architecture (32-bit and 64-bit) · Maintainers:
Catalin Marinas, Will Deacon, Paolo Bonzini, Marc Zyngier, Oliver Upton, Huacai Chen, Madhavan Srinivasan, Anup Patel, Sean Christopherson, Christian Borntraeger, Janosch Frank, Claudio Imbrenda, Michael Ellerman, Thomas Bogendoerfer, Paul Walmsley, Palmer Dabbelt, Albert Ou, Heiko Carstens, Vasily Gorbik, Alexander Gordeev, Linus Torvalds, Thomas Gleixner, Ingo Molnar, Borislav Petkov, Dave Hansen
Drop the @mem param from kvm_arch_{prepare,commit}_memory_region() now
that its use has been removed in all architectures.
No functional change intended.
