patch to add LINUX_SYS_linux_getcpu to linux_vsyscall
The linux java packaged with the ADVA NMS SIGSEGV:
# A fatal error has been detected by the Java Runtime Environment:
#
# SIGSEGV (0xb) at pc=0xffffffffff600800, pid=12763, tid=101256
#
# JRE version: (11.0.4+11) (build )
# Java VM: OpenJDK 64-Bit Server VM (11.0.4+11, mixed mode, aot, sharing,
tiered, compressed oops, g1 gc, linux-amd64)
# Problematic frame:
# C 0xffffffffff600800
That is when it is trying to execute the vsyscall linux_getcpu.
Just by adding it, even though it is not implemented, allow their java to
continue and the NMS is working.
The patch is simple:
