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.
