Hello!

It turns out KVM relies on the inline hint being honoured by the compiler
in quite a few more places than expected. Something about the Shadow Call
Stack support[0] causes the compiler to avoid inline-ing and to place
these functions outside the __hyp_text. This ruins KVM's day.

Add the simon-says __always_inline annotation to all the static
inlines that KVM calls from HYP code.

This series based on v5.6-rc2.

This isn't quite as yuck as I expected, fortunately, but it does beg
the question whether we shouldn't simply map the entire kernel at EL2
instead?
