[Bug libc/12447] New: please provide a VDSO stub for getcpu


http://sourceware.org/bugzilla/show_bug.cgi?id=12447

           Summary: please provide a VDSO stub for getcpu
           Product: glibc
           Version: unspecified
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: libc
        AssignedTo: drepper.fsp@gmail.com
        ReportedBy: madcoder@debian.org


On the architecture, linux provides a VDSO entry for getcpu, please export a
definition for it.

The prototype for it is:

struct getcpu_cache {
    unsigned long blob[128 / sizeof(long)];
};

long vgetcpu(unsigned *cpu, unsigned *node, struct getcpu_cache *tcache);
