I will use __section(section) in the updated patch.

I don't know whether it is worth for a new version for a relatively large patchset
with almost 50 patches since the feedback becomes less or I should wait for more
reviews from the x86 maintainers.  Especially the second half of the patchset which
is all about IST exceptions has no feedback since V2.

Thanks.
