[PATCH v4 07/12] KVM: arm64: selftests: Finish generalizing get-reg-list
From: Haibo Xu <hidden>
Date: 2023-06-23 10:36:58
Also in:
kvm, kvm-riscv, kvmarm, linux-doc, linux-kselftest, linux-riscv, lkml
Subsystem:
kernel selftest framework, kernel virtual machine (kvm), the rest · Maintainers:
Shuah Khan, Paolo Bonzini, Linus Torvalds
From: Andrew Jones <redacted> Add some unfortunate #ifdeffery to ensure the common get-reg-list.c can be compiled and run with other architectures. The next architecture to support get-reg-list should now only need to provide $(ARCH_DIR)/get-reg-list.c where arch-specific print_reg() and vcpu_configs[] get defined.
