Changelog:
*v1 -> v2: reverse PageTransHuge(page) && !PageHuge(page) check
PageTransHuge() can't guarantee the page is transparent huge page since it
return true for both transparent huge and hugetlbfs pages. This patch fix
it by check the page is also !hugetlbfs page.

Well, there is no need to use strcmp since we can make a test of similar
semantic by using the var_id field of param.
I moved the test into the VAR_NUM:VAR_TIME case since VAR_STRING will never be
"voice".
spk_xlate isn't used anymore (in line 628), then there is no difference between
using cp
Spaces around trigraphs are specified by CodingStyle
but checkpatch is currently silent about them because

Hi,
I'm not very familiar with the tracing framework, but I will try to
comment on your questions.

Running completely virtualised, system Z severely lacks good true random
sources.
Gathering entropy in a virtual environment is difficult. To compensate, there is
specialised crypto hardware which includes a source for hardware randomness;
the zcrypt driver is able to access this random source.
This patch adds an interface to the random pool for feeding entropy in-kernel.
It might be dangerous when some driver writers think they have "good"
randomness when really they haven't.

Hi Ted!
A while ago a colleague asked me if it was possible to speed up system
startup on IBM system Z that was slow because of ASLR and the entropy pool
was empty. They had recently intoduced new crypto cards that featured good
hardware random generators. My resulting code has meanwhile taken

Yes. And everything else looks fine too.
Kirill, thank you for the comment.

The use of extern in .h files is a bit contentious.
Make it emitted only when --strict is used on the
command-line.
