[PATCH] The size of CPU sets, __CPU_SETSIZE is too small

[Changsheng.Liu]

From: Changsheng Liu <liuchangsheng@inspur.com>

Now the size of struct cpu_set_t is 1024 bits,
But there are many thousands of cores in the server
and the cpumask in the Linux Kernel has been expanded to
5120 bits (CONFIG_NR_CPUS=5120).
So in this patch the size of CPU sets is expanded to 5120
for the server that has many thousands of cores
