Indeed. We could also make this transparent to userspace by using a script
to copy the user-* headers to /usr/include. Something like this:

install_user_headers:
$(srctree)/scripts/install_user_headers.sh

#!/bin/bash
rm -rf /usr/include/asm /usr/include/linux /usr/include/asm-generic
mkdir /usr/include/asm /usr/include/linux /usr/include/asm-generic

to_user() {
sed -e 's,<user/,<linux/, \
-e 's,<user-generic/,<asm-generic,' \
-e 's,<user-[^/]*/,<asm,' \
<$1 >$2
}

for src in include/user/*; do
to_user $src /usr/include/linux/`basename $src`
done

for src in include/user-$ARCH/*; do
to_user $src /usr/include/asm/`basename $src`
done

for src in include/user-generic/*; do
to_user $src /usr/include/asm-generic/`basename $src`
done


If we really wanted to get fancy, we could also sed __u32 to uint32_t.
But that would probably cause more pain, confusion, hurt and bad feeling
than I'd ever want to be responsible for.

conscience-soothing falsities, and will diligently study them, and refuse
to examine any refutations of them; and thus he will by and by convince
himself that the war is just, and will thank God for the better sleep
he enjoys after this process of grotesque self-deception." -- Mark Twain
