In some scenarios, some multipath software setup places the
REQ_FAILFAST_DEV flag on I/O to prevent retries and immediately
switch to other paths for issuing I/O commands. This will reflect
on the NVMe read and write commands with the limited retry flag.
However, the current NVMe target side does not handle the limited
retry flag, and the target's underlying driver still retries the
I/O. This will result in the I/O not being quickly switched to
other paths, ultimately leading to increased I/O latency.
When the nvme target receive an rw command with limited retry flag,
handle it in block backend by setting the REQ_FAILFAST_DEV flag to
bio.

In commit 77b5334115 ("KVM: s390: VSIE: sort out virtual/physical
address in pin_guest_page"), only pin_scb() has been updated. This
means that in unpin_scb() a virtual address was still used directly as
physical address without conversion. The resulting physical address is
obviously wrong and most of the time also invalid.
Since commit d0ef8d9fbe ("KVM: s390: Use kvm_release_page_dirty() to
unpin "struct page" memory"), unpin_guest_page() will directly use
kvm_release_page_dirty(), instead of kvm_release_pfn_dirty(), which has
since been removed.
One of the checks that were performed by kvm_release_pfn_dirty() was to
verify whether the page was valid at all, and silently return
successfully without doing anything if the page was invalid.
When kvm_release_pfn_dirty() was still used, the invalid page was thus
silently ignored. Now the check is gone and the result is an Oops.
This also means that when running with a V!=R kernel, the page was not
released, causing a leak.
The solution is simply to add the missing virt_to_phys().

If additional devices are not present, the address returned is zero.
Currently, the code does not check for this condition, resulting in
ioremap() incorrectly attempting to map address 0.
Add a check for a zero address and return 0 if no additional devices

Geert reported that my previous short fops debugfs changes
broke m68k, because it only has mandatory alignement of two,
so we can't stash the "is it short" information into the
pointer (as we already did with the "is it real" bit.)
Instead, exploit the fact that debugfs_file_get() called on
an already open file will already find that the fsdata is
no longer the real fops but rather the allocated data that
already distinguishes full/short ops, so only open() needs
to be able to distinguish. We can achieve that by using two
different open functions.
Unfortunately this requires another set of full file ops,
increasing the size by 536 bytes (x86-64), but that's still
a reasonable trade-off given that only converting some of
the wireless stack gained over 28k. This brings the total
cost of this to around 1k, for wins of 28k (all x86-64).
