As of commit ba470de431 ("map: handle
mlocked pages during map, remap, unmap") we now use the 'vma' variable
at the end of mmap_region() to handle the page-in of newly mapped
mlocked pages.
However, if we merged adjacent vma's together, the vma we're using may
be stale. We historically consciously avoided using it after the merge
operation, but that got overlooked when redoing the locked page
handling.
This commit simplifies mmap_region() by doing any vma merges early,
avoiding the issue entirely, and 'vma' will always be valid. As pointed
out by Hugh Dickins, this depends on any drivers that change the page
offset of flags to have set one of the VM_SPECIAL bits (so that they
cannot trigger the early merge logic), but that's true in general.

According to https://bugs.launchpad.net/bugs/294391
- 3rd generation iPods need the "fix capacity" workaround after all
(apparently they crash after the last sector was accessed),
- 2nd generation iPods need the "128 kB maximum request size"
workaround.
Alas both iPod generations feature the same model ID in the config ROM,
hence we can only define a shared quirks list entry for them. Luckily
the fix capacity workaround did not show a negative effect in Jarod's
tests with 2nd gen. iPod.
A side note: Apple computers in target mode (or at least an x86 Mac
mini) don't have firmware_version and model_id, hence none of the iPod
quirks list entries is active for them.

cifs: turn smb_send into a wrapper around smb_sendv
Rename smb_send2 to smb_sendv to make it consistent with kernel naming
conventions for functions that take a vector.
There's no need to have 2 functions to handle sending SMB calls. Turn
smb_send into a wrapper around smb_sendv. This also allows us to
properly mark the socket as needing to be reconnected when there's a
partial send from smb_send.
Also, in practice we always use the address and noblocksnd flag
that's attached to the TCP_Server_Info. There's no need to pass
them in as separate args to smb_sendv.

This makes sbp2 behave more like firewire-sbp2 which reports 0xff000000
as immediate value if there are no unit directory entries for model_id
or firmware_revision.
It does not reduce matches with the currently existing quirks table; the
only zero entry there is for a device which actually does have a zero
model_id. It only changes how model_id and firmware_revision are logged
if they are missing.
Other functionally unrelated changes: The model_id member of quirks
list entries is renamed to model; the value (but not the effect) of
SBP2_ROM_VALUE_WILDCARD is changed. Now this part of the source is
identical with firewire-sbp2 for easier maintenance.

In the VIO bus code the wrappers for dma alloc_coherent and free_coherent
calls are rounding to IOMMU_PAGE_SIZE. Taking a look at the underlying
calls, the actual mapping is promoted to PAGE_SIZE. Changing the
rounding in these two functions fixes under-reporting the entitlement
used by the system. Without this change, the system could run out of
entitlement before it believes it has and incur mapping failures at the
firmware level.
Also in the VIO bus code, the wrapper for dma map_sg is not exiting in
an error path where it should. Rather than fall through to code for the
success case, this patch adds the return that is needed in the error path.
