This saves looking up one symbol for a debug function that is not
used anywhere

1543119139 mcctrl rus_vm_fault: tpe changed with kernel >= 4.11 
vma is part of vmf and isn't needed, so type changed (see linux 11bac80
("mm, fs: reduce fault, [...] to take only vmf"))

0a0a78ac2e mcctrl: replace GFP_TEMPORARY by GFP_KERNEL 
See linux's commit 0ee931c4 ("mm: treewide: remove GFP_TEMPORARY
allocation flag") for a long explanation, but basically that flag
"is just cargo cult" and should be removed

do_frees is allowed to be NULL only if free_addrs_count is 0, but that

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
