Hi all,The backport "arm64: KVM: Fix SMCCC handling of unimplemented SMC/HVC calls" (26bfa48da661f380e53780e148cbf30e8f2b8c9c) is breaking compilation on arm64 due to a missing helper.
This helper was added in commit bc45a516fa90b43b1898758d8b53b74c24b954e4 "arm64: KVM: Correctly handle zero register during MMIO" and conveniently fix another potential bug in Linux 4.1.
Would it be possible to backport this to Linux 4.1? Cheers, -- Julien Grall
