Subject: [PATCH v3 5/5] KVM: selftests: Remove __NR_userfaultfd syscall fallback
Date: Wed, 1 Sep 2021 13:30:30 -0700 [thread overview]
Message-ID: <20210901203030.1292304-6-seanjc@google.com> (raw)
In-Reply-To: <20210901203030.1292304-1-seanjc@google.com>
Revert the __NR_userfaultfd syscall fallback added for KVM selftests now
that x86's unistd_{32,63}.h overrides are under uapi/ and thus not in
KVM sefltests' search path, i.e. now that KVM gets x86 syscall numbers
from the installed kernel headers.
No functional change intended.
