ab8fe0bbbf mcctrl: convert perf ctrl ioctls to mcctrl_ihk_send_wait 
While we are here, also optimize code a bit: perf_desc does not need
to be allocated for every cpu; and fix coding style.

b939ca9370 mcctrl: refactor prepare_image into new generic ikc send&wait 
Many ikc messages expecting a reply use wait_event_interruptible
incorrectly, freeing memory that could still be used on the other side.

This commit implements a generic ikc send and wait helper that helps
with memory management and ownership properly:
 - if the message succeeds and a reply comes back normally, the memory
is freed by the caller as usual
 - if the wait fails (signal before the reply comes or timeout) then the
memory is set as owner by ikc and will be free when the reply comes back
later
 - if the reply never comes, the memory is freed at shutdown when
destroying ikc channels

d4471df94e execve: use thread variable instead of cpu_local_var(current)

fork() execve() / wait() in a loop
