coordinates which never reach 0 along one or both of their axis.
This has been seen for example on the Silead touchscreens on a Onda V891w
and a Point of View mobii TAB-P800w(v2.0).
This commit adds support for touchscreen-min-x and touchscreen-min-y
device-properties which can be set to communicate the actual start
coordinates (rather then 0,0) to userspace.
This commit also drop the "(in pixels)" comment from the documentation
of the touchscreen-size-x and touchscreen-size-y properties. The comment
suggested that there is a relation between the range of reported
coordinates and the display resolution, which is only true for some
devices. The "(in pixels)" comment is replaced with "(maximum x coordinate
reported + 1)" to mirror the language describing the new touchscreen-min-x

Revert "fs: fold open_check_o_direct into do_dentry_open"
fix io_destroy()/aio_complete() race

Revert "fs: fold open_check_o_direct into do_dentry_open"
This reverts commit
cab64df194667dc5d9d786f0a895f647f5501c0d.
Having vfs_open() in some cases drop the reference to
struct file combined with
error = vfs_open(path, f, cred);
if (error) {
put_filp(f);
return ERR_PTR(error);
}
return f;
is flat-out wrong. It used to be
error = vfs_open(path, f, cred);
if (!error) {
/* from now on we need fput() to dispose of f */
error = open_check_o_direct(f);
if (error) {
fput(f);
f = ERR_PTR(error);
}
} else {
put_filp(f);
f = ERR_PTR(error);
}
and sure, having that open_check_o_direct() boilerplate gotten rid of is
nice, but not that way...
Worse, another call chain (via finish_open()) is FUBAR now wrt
FILE_OPENED handling - in that case we get error returned, with file
already hit by fput() *AND* FILE_OPENED not set. Guess what happens in
path_openat(), when it hits
if (!(opened & FILE_OPENED)) {
BUG_ON(!error);
put_filp(file);
}
The root cause of all that crap is that the callers of do_dentry_open()
have no way to tell which way did it fail; while that could be fixed up
(by passing something like int *opened to do_dentry_open() and have it
marked if we'd called ->open()), it's probably much too late in the
cycle to do so right now.

- two patches addressing the problem that the scheduler allows under
certain conditions user space tasks to be scheduled on CPUs which are
not yet fully booted which causes a few subtle and hard to debug
issue
- add a missing runqueue clock update in the deadline scheduler which
triggers a warning under certain circumstances

"Eve of merge window fix: The original code was so bogus as to be
casting the wrong generic device to an rport and proceeding to take

Fortunately it seems the location that is dereferenced always exists,
so the code hasn't oopsed yet, but it certainly annoys the memory
