Hi all,
After merging the kvm tree, today's linux-next build (arm64 defconfig)
failed like this:
arch/arm64/kvm/psci.c: In function 'kvm_prepare_system_event':
arch/arm64/kvm/psci.c:184:32: error: 'struct <anonymous>' has no member named 'flags'
184 | vcpu->run->system_event.flags = flags;
| ^
Caused by commit
c24a950ec7d6 ("KVM, SEV: Add KVM_EXIT_SHUTDOWN metadata for SEV-ES")
In this commit, the uapi structure changes do not match the documentation
changes :-( Does it matter that the ABI may be changed by this commit
(depending on the alignment of the structure members)?
I have added the following patch or today:
