It's tracing_cpumask_new that should be kfree()ed.

This causes tracing_cpumask to be freed due to the typo:

 # echo z > tracing_cpumask
 bash: echo: write error: Invalid argument

And subsequent reads/writes to tracing_cpuamsk will access this
already-freed tracing_cpumask, thus may lead to crash.

when compiling linux-mips with kmemtrace enabled, there will be an

I checked the source code and found trace_seq.h used PAGE_SIZE but not
included the relative header file, so, fix it via adding the header file
