Why do you export these? I know x86 exports those as well, but
it shoudn't be needed there either.
I export these to be in line with the x86 implementation (which
is the original and seems to be the only one at the moment). I assumed
that 'exported or not' is kind of a part of the interface definition.
Honestly, I did not give it too much thought.
For x86 set_memory(en|de)crypted got exported by 95cf9264d5f3 "x86, drm,
fbdev: Do not specify encrypted memory for video mappings" (Tom
Lendacky, 2017-07-17). With CONFIG_FB_VGA16=m seems to be necessary for x84.
If the consensus is don't export: I won't. I'm fine one way or the other.
@Christian, what is your take on this?
If we do not need it today for anything (e.g. virtio-gpu) then we can get rid
of the exports (and introduce them when necessary).
I'll take them out then.
Thank you very much!
