staging/lustre/llite: Make sure ft_flags is valid
In ll_fault0, the 'fault' struct is mostly cleared before the call to
cl_io_loop, but ft_flags is not reset. It is ordinarily set by
the call to filemap_fault in vvp_io_kernel_fault, but if Lustre
returns before calling filemap_fault, it still has the old value of
ft_flags.
ll_fault0 will then consume the ft_flags field. If it has the
VM_FAULT_RETRY bit set, it will be used as ll_fault0() and
ll_fault()'s return value.
This is a problem when VM_FAULT_RETRY is in ft_flags:
When fault/filemap_fault return with that flag set, they have already
released the mmap semaphore, and do_page_fault does not need to
release it.
Incorrectly returning this flag from ll_fault means mmap_sem
is not upped in the kernel's do_page_fault().
In addition to clearing ft_flags, this patch does not use it unless
it is valid. It's potentially misleading to return ft_flags in
"fault_ret" if ft_flags has not been set by filemap_fault.
This adds clarity, but does not change the current behavior:
When not valid, ft_flags is replaced by fault_ret, which is zero,
as is ft_flags when not set by filemap_fault.

staging: comedi: 8255: refactor how the (*io) function works
Currently, all users of is module that use the default (*io) function
pass an 'iobase' to subdev_8255_init() of the form:
dev->iobase + OFFSET_TO_8255_BASE_REG
Now that the (*io) callback includes the comedi_device 'dev' pointer
the 'dev->iobase' does not need to be included.
Modify the default (*io) function, subdev_8255_io(), to automatically
add the dev->iobase to the address when reading/writing the port.
For aesthetics, rename the subdevice private data member to 'regbase'.
Also, rename the local variables in this module that are used to
access this member.
Add a comment in dev_8255_attach() about the 'iobase' that is passed
to subdev_8255_init(). For manually attached 8255 devices the io
region is requested with __comedi_request_region() which does not
set dev->iobase. For these devices the 'regbase' is actually the
'iobase'.
Remove the, now unnecessary, dev->iobase from all the callers of
subdev_8255_init(). There are a couple drivers that only passed the
dev->iobase. For those drivers pass a 'regbase' of 0x00.
Note that the das16m1 driver is a bit goofy. The devpriv->extra_iobase
is requested using __comedi_request_region() which does not set the
dev->iobase. But the starting address passed is dev->iobase + DAS16M1_82C55
so a 'regbase' of DAS16M1_82C55 is passed to subdev_8255_init().
