Add an ->ioctl method to the dasd_discipline structure. This allows to apply
the same kind of cleanups the last patch applied to dasd_ioctl.c to
dasd_eckd.c (the only dasd discipline with special ioctls) aswell.
Again lots of code removed. During auditing the ioctls I found two fishy
return value propagations from copy_{from,to}_user, maintainers please check
those, I've marked them with XXX comments.

Handle ioctls implemented in dasd_ioctl through the normal switch statement
that most drivers use instead of the awkward dasd_ioctl_no_register routine.
This avoids searching a linear list on every call to dasd_ioctl(), and allows
to give the various ioctl implementation functions sane prototypes, aswell as
moving the check for bdev->bd_disk->private_data from the individual functions
to dasd_ioctl. (I think it can't actually every be NULL, but let's keep that
for later)

When cio waits for the interrupt for a basic sense, interrupts for hsch() or
csch() issued in the meantime are wrongly counted as interrupts for the basic
sense and the accumulated irb is passed to the device driver. In
ccw_device_w4sense(), check for clear or halt function in the irb and pass the
irb for the csch() or hsch() to the device driver.

While working on these patch set, I found several possible cleanup on x86-64
and ia64.
akpm: I stole this from Andi's queue.
Not only does it clean up bitops. It also unrelatedly changes the prototype
of pci_mmcfg_init() and removes its arch_initcall(). It seems that the wrong
two patches got joined together, but this is the one which has been tested.
This patch fixes the current x86_64 build error (the pci_mmcfg_init()
declaration in arch/i386/pci/pci.h disagrees with the definition in
arch/x86_64/pci/mmconfig.c)
This also means that x86_64's pci_mmcfg_init() gets called in the same (new)
manner as x86's: from arch/i386/pci/init.c:pci_access_init(), rather than via
initcall.
The bitops cleanups came along for free.
All this worked OK in -mm testing (since 2.6.16-rc4-mm1) because x86_64 was
tested with both patches applied.

The meaning of MS_VERBOSE is backwards; if the bit is set, it really means,
"don't be verbose". This is confusing and counter-intuitive.
In addition, there is also no way to set the MS_VERBOSE flag in the
mount(8) program in util-linux, but interesting, it does define options
which would do the right thing if MS_SILENT were defined, which
unfortunately we do not:
#ifdef MS_SILENT
{ "quiet", 0, 0, MS_SILENT }, /* be quiet */
{ "loud", 0, 1, MS_SILENT }, /* print out messages. */
#endif
So the obvious fix is to deprecate the use of MS_VERBOSE and replace it
with MS_SILENT.
