src/hotspot/os/linux/systemMemoryBarrier_linux.cpp:65:18: error: 'SYS_membarrier' was not declared in this scope
   return syscall(SYS_membarrier, cmd, flags, cpu_id); // cpu_id only on >= 5.10
                  ^~~~~~~~~~~~~~

We need to add a SYS_membarrier definition in systemMemoryBarrier_linux.cpp for x86 as well:

#ifndef SYS_membarrier
  #if defined(AMD64)
  #define SYS_membarrier 324
  #elif defined(PPC64)
  #define SYS_membarrier 365
  #elif defined(AARCH64)
  #define SYS_membarrier 283
  #elif defined(ALPHA)
  #define SYS_membarrier 517
  #else
  #error define SYS_membarrier for the arch
  #endif
#endif // SYS_membarrier
