Subject: [RFC PATCH 1/2] Explicitly include linux/major.h where it is needed

This is in preparation for removing the include of major.h where it is
not needed.

These files were found using

	grep -E -L '[<"](uapi/)?linux/major\.h' $(git grep -l -w -f /tmp/xx)

where /tmp/xx contains all the symbols defined in major.h.  There were
a couple of files in that list that did not need the include since the
references are in comments.
