None of these files use any of the functionality promised by
asm/semaphore.h. It's possible that they rely on it dragging in some
unrelated header file, but I can't build all these files, so we'll have
fix any build failures as they come up.

Most noteable part of this commit is the new local header file entry.h
which contains all the function declarations of functions that get only
called from asm code or are arch internal. That way we can avoid extern
declarations in C files.
This is more or less the same that was done for sparc64.

drivers/s390/sysinfo.c uses the store system information intruction to query
the system about information of the machine, the LPAR and additional
hypervisors. KVM has to implement the host part for this instruction.
To avoid code duplication, this patch splits the common definitions from
sysinfo.c into a separate header file include/asm-s390/sysinfo.h for KVM use.

If user space opens a unit record device node then vmur is leaving the kernel
with lock open_mutex still held to prevent other processes from opening the
device simultaneously. This causes lockdep to complain about a lock held when
returning to user space.
Now the mutex is replaced by a wait queue to serialize device open.

When a tape device is set online, offline and online again, the following
error message is printed on the console: "sysfs: duplicate filename
'non-rewinding' can not be created". The reason is that when setting a
device online, the tape driver creates a sysfs symlink from the tape device
to the tape class device. Unfortunately the symlink is not removed
correctly, when the device is set offline. Instead of passing the
tape device object to sysfs_remove_link, the class device object is used.
This patch fixes this problem and uses the correct tape device object now.

Problem:
Usually every FCP device has its own indicator field the adapter
uses to signal outstanding work. Once a certain limit of devices
is reached, a common indicator field is used. In certain scenarios
qdio resets this common indicator field, but handles only part of
the FCP-devices sharing the common indicator field. Thus inbound
traffic on the non-processed shared FCP-devices is not recognized
immediately.
Solution:
Make sure common indicator field is reset only, if all FCP-devices
sharing the indicator are processed.
