    Compile on the ARM panda fails because commit 615399c8 removed the defines of:

    cpu_online_map
    cpu_possible_map

    These defines are used by posix-timers-thread-posix-cpu-timers-on-rt.patch


    kernel/posix-cpu-timers.c: In function 'posix_cpu_thread_call':
    kernel/posix-cpu-timers.c:1487: error: 'cpu_online_map' undeclared (first use in this function)
    kernel/posix-cpu-timers.c:1487: error: (Each undeclared identifier is reported only once
    kernel/posix-cpu-timers.c:1487: error: for each function it appears in.)
    kernel/posix-cpu-timers.c: In function 'posix_cpu_thread_init':
    kernel/posix-cpu-timers.c:1515: error: 'cpu_possible_map' undeclared (first use in this function)


    This patch is a temporary workaround, putting back two of the defines removed
    by commit 615399c8.
