Note: the original fujitsu implementation didn't rename the various
save_fs function/desc to save_tls for some reason, might as well go all
the way though...

arm64 performs context-switch in kernel space instead of user space as in
x86_64.

This fix is rejected because it only makes the setfsuid test in ostest
pass and doesn't fix the other issues including the one in which file
I/O could be done with the old fsuid because an mcexec thread with an
arbitrary tid could handle the system-call offload request.
Explanation of the rejected fix:
setfsuid() proceeds as follows:
1. McKernel asks mcexec for __NR_setfsuid (set)
2. mcexec calls setfsuid, reports the id to McKernel
3. McKernel asks mcexec for __NR_setfsuid (get)
4. mcexec calls mcexec_getcred(), reports the id to Mckernel
5. McKernel sets proc->fsuid to the obtained value
tid of mcexec on the 2nd and 4th step could be different. So this
fix lets mcexec report its tid on the 2nd step and McKernel specify
it in the 3rd step.

arch perf counters are placed at start, so offset all
other counters (because placing arch perf counters at the end
wouldn't have been intrusive enough?)

ihk_ikc_release_packet takes the channel and puts the packet into its
free-list. This fix makes it easy and safe to identify the proper
channel.

will work for el7 and older kernels as well

usrdata->perf_event_num with number of registered events.
