The 32 bit addition "(hangcheck_margin + hangcheck_tick)" could
potentially overflow.  It triggers a static checker warning to have an
overflowed addition followed by a no-op cast.  I have moved the cast so
that the addition can't overflow.

Also I removed the unneeded cast on the following line since both
"hangcheck_tsc_margin" and "TIMER_FREQ" are already 64 bit types.

bus_find_device_by_name() acquires a device reference which is never
released.  This results in an object leak, which on older kernels
results in failure to release all resources of PCI devices.  libvirt
uses drivers_probe to re-attach devices to the host after assignment
and is therefore a common trigger for this leak.

Example:

# cd /sys/bus/pci/

`genwqe_user_vmap()` calls `get_user_pages_fast()` and if the return
value is less than the number of pages requested, it frees the pages and
returns an error (`-EFAULT`).  However, it fails to consider a negative
error return value from `get_user_pages_fast()`.  In that case, the test
`if (rc < m->nr_pages)` will be false (due to promotion of `rc` to a
large `unsigned int`) and the code will continue on to call
`genwqe_map_pages()` with an invalid list of page pointers.  Fix it by
bailing out if `get_user_pages_fast()` returns a negative error value.

the miscdevice core now does the work in any case.
Signed-off-by: Martin Kepplinger <martink@posteo.de>
Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

As of now, a miscdevice driver has to provide an implementation of
the open() file operation if it wants to have misc_open() assign a
pointer to struct miscdevice to file->private_data for other file
operations to use (given the user calls open()).

This leads to situations where a miscdevice driver that doesn't need
internal operations during open() has to implement open() that only
returns immediately, in order to use the data in private_data in other
fops.

This provides consistent behaviour for miscdevice developers and will
always provide the pointer in private_data. A driver's open() fop would,
of course, just overwrite it, when using private_data itself.

An attempt to fix fcopy on i586 (bc5a5b02 Drivers: hv: util: Properly pack the data
for file copy functionality) led to a regression on x86_64 (and actually didn't fix
i586 breakage). Fcopy messages from Hyper-V host come in the following format:

struct do_fcopy_hdr   |   36 bytes
0000                  |    4 bytes
offset                |    8 bytes
size                  |    4 bytes
data                  | 6144 bytes

On x86_64 struct hv_do_fcopy matched this format without ' __attribute__((packed))'
and on i586 adding ' __attribute__((packed))' to it doesn't change anything. Keep
the structure packed and add padding to match re reality. Tested both i586 and x86_64
on Hyper-V Server 2012 R2.

All tools/hv daemons do mandatory daemon() on startup. However, no pidfile
is created, this make it difficult for an init system to track such daemons.
Modern linux distros use systemd as their init system. It can handle the
daemonizing by itself, however, it requires a daemon to stay in foreground
for that. Some distros already carry distro-specific patch for hv tools
which switches off daemon().

The scripts/checkkconfigsymbols.sh script searches Kconfig features
in the source code that are not defined in Kconfig. Such identifiers
always evaluate to false and are the source of various kinds of bugs.
However, the shell script is slow and it does not detect such broken
references in Kbuild and Kconfig files (e.g., ``depends on UNDEFINED´´).
Furthermore, it generates false positives. The script is also hard to
read and understand, and is thereby difficult to maintain.

This patch replaces the shell script with an implementation in Python,
which:
    (a) detects the same bugs, but does not report previous false positives
    (b) additionally detects broken references in Kconfig and all
        non-Kconfig files, such as Kbuild, .[cSh], .txt, .sh, defconfig, etc.
    (c) is up to 75 times faster than the shell script
    (d) only checks files under version control

The new script reduces the runtime on my machine (i7-2620M, 8GB RAM, SSD)
from 3m47s to 0m3s, and reports 938 broken references in Linux v3.17-rc1;
419 additional reports of which 16 are located in Kconfig files,
287 in defconfigs, 63 in ./Documentation, 1 in Kbuild.

Moreover, we intentionally include references in comments, which have been
ignored until now. Such comments may be leftovers of features that have
been removed or renamed in Kconfig (e.g., ``#endif /* CONFIG_MPC52xx */´´).
These references can be misleading and should be removed or replaced.

Note that the output format changed from (file list <tab> feature) to
(feature <tab> file list) as it simplifies the detection of the Kconfig
feature for long file lists.

   - A regression from 3.16 which was noticed in 3.17.  With the

     framework, we omitted proper listing of the SPI device IDs.  This
     means m25p80.c wouldn't auto-load (modprobe) properly when built as
     a module.  For now, we duplicate the device IDs into both modules.

   - The OMAP / ELM modules were depending on an implicit link ordering.
     Use deferred probing so that the new link order (in 3.18-rc) can
     still allow for successful probing.
