Align Kconfig and Kbuild logic to Linux 4.18 release with minimal impact
on files outside of this scope.
Our previous Kconfig sync was done by commit e91610da7c
("kconfig:
re-sync with Linux 4.17-rc4").
A very small number of changes upstream since our sync with v4.17-rc4
that exist in the v4.18 release have already been applied here and have
been omitted from the list in this commit (and are readily available in
our own git history).
The imported Linux commits are:

* Changes by Clifford Wolf (god@clifford.at)
|
|
*
|
|
* [ 1998-06-13 ]
|
|
*
|
|
* *) A bugfix for the Page-Down problem
|
|
*
|
|
* *) Formerly when I used Page Down and Page Up, the cursor would be set
|
|
* to the first position in the menu box. Now lxdialog is a bit
|
|
* smarter and works more like other menu systems (just have a look at
|
|
* it).
|
|
*
|
|
* *) Formerly if I selected something my scrolling would be broken because
|
|
* lxdialog is re-invoked by the Menuconfig shell script, can't
|
|
* remember the last scrolling position, and just sets it so that the
|
|
* cursor is at the bottom of the box. Now it writes the temporary file
|
|
* lxdialog.scrltmp which contains this information. The file is
|
|
* deleted by lxdialog if the user leaves a submenu or enters a new
|
|
* one, but it would be nice if Menuconfig could make another "rm -f"
|
|
* just to be sure. Just try it out - you will recognise a difference!
|
|
*
|
|
* [ 1998-06-14 ]
|
|
*
|
|
* *) Now lxdialog is crash-safe against broken "lxdialog.scrltmp" files
|
|
* and menus change their size on the fly.
|
|
*
|
|
* *) If for some reason the last scrolling position is not saved by
|
|
* lxdialog, it sets the scrolling so that the selected item is in the
|
|
* middle of the menu box, not at the bottom.
|
|
*
|
|
* 02 January 1999, Michael Elizabeth Chastain (mec@shout.net)
|
|
* Reset 'scroll' to 0 if the value from lxdialog.scrltmp is bogus.
|
|
* This fixes a bug in Menuconfig where using ' ' to descend into menus
|
|
* would leave mis-synchronized lxdialog.scrltmp files lying around,
|
|
* fscanf would read in 'scroll', and eventually that value would get used.
