Currently IO resources are mapped 1 to 1 with RQ buffers posted
Added logic to separate RQE buffers from IO op resources
(sgl/iocbq/context). During initialization, the driver will determine
how many SGLs it will allocate for NVMET (based on what the firmware
reports) and associate a NVMET IOCBq and NVMET context structure with
each one.
Now that hdr/data buffers are immediately reposted back to the RQ, 512
RQEs for each MRQ is sufficient. Also, since NVMET data buffers are now
128 bytes, lpfc_nvmet_mrq_post is not necessary anymore as we will
always post the max (512) buffers per NVMET MRQ.

During driver boot, a latency in the NVMET driver side causes the
incoming NVMEI PRLI to get rejected by the NVMET driver. When this
happens, the NVMEI driver runs out of PRLI retries. Bouncing the link
does not fix the situation.
If the NVMEI driver decides, on PRLI completion failures, to retry the
PRLI, always decrement the fc4_prli_sent counter. This allows the PRLI
completion to resolve to UNMAPPED when NVMET rejects the PRLI.

When a device is unplugged from a SCSI controller, if the scsi_device is
still in use by application layer, it won't get released until users
close it.
In this case, scsi_device_remove just set the scsi_device's state to be
SDEV_DEL. But if you plug the disk just before the old scsi_device is
released, then there will be two scsi_device structures in
scsi_host->__devices. When the next unplug event happens, some low-level
drivers will check whether the scsi_device has been added to host (for
example the MegaRAID SAS series controller) by calling
scsi_device_lookup(call __scsi_device_lookup) in function
megasas_aen_polling. __scsi_device_lookup will return the first
scsi_device. Because its state is SDEV_DEL, the scsi_device_lookup will
return NULL, making the low-level driver assume that the scsi_device has
been removed, and won't call scsi_device_remove which will lead to hot
swap failure.

To select the appropriate shost template, the driver is issuing a
mailbox command to retrieve the wwn. Turns out the sending of the
command precedes the reset of the function. On SLI-4 adapters, this is
inconsequential as the mailbox command location is specified by dma via
the BMBX register. However, on SLI-3 adapters, the location of the
mailbox command submission area changes. When the function is first
powered on or reset, the cmd is submitted via PCI bar memory. Later the
driver changes the function config to use host memory and DMA. The
request to start a mailbox command is the same, a simple doorbell write,
regardless of submission area. So.. if there has not been a boot driver
run against the adapter, the mailbox command works as defaults are
ok. But, if the boot driver has configured the card and, and if no
platform pci function/slot reset occurs as the os starts, the mailbox
command will fail. The SLI-3 device will use the stale boot driver dma
location. This can cause PCI eeh errors.
Fix is to reset the sli-3 function before sending the mailbox command,
thus synchronizing the function/driver on mailbox location.
Note: The fix uses routines that are typically invoked later in the call
flow to reset the sli-3 device. The issue in using those routines is
that the normal (non-fix) flow does additional initialization, namely
the allocation of the pport structure. So, rather than significantly
reworking the initialization flow so that the pport is alloc'd first,
pointer checks are added to work around it. Checks are limited to the
routines invoked by a sli-3 adapter (s3 routines) as this fix/early call
is only invoked on a sli3 adapter. Nothing changes post the
fix. Subsequent initialization, and another adapter reset, still occur -
both on sli-3 and sli-4 adapters.

Now that kref is using the refcount apis, the _GPL markings are getting
exported to places that it previously wasn't. Now kref.h is GPLv2
licensed, so any non-GPL code using it better be talking to some
lawyers, but changing api markings isn't considered "nice", so let's fix
this up.

Since 2014, you can't successfully build kernels with GNU Make version
3.80. Example errors:
$ git describe
v4.11
$ make --version | head -1
GNU Make 3.80
$ make defconfig
HOSTCC scripts/basic/fixdep
scripts/Makefile.host:135: *** missing separator. Stop.
make: *** [defconfig] Error 2
$ make ARCH=arm64 help

$ make help >/dev/null
./Documentation/Makefile.sphinx:25: Extraneous text after `else' directive
./Documentation/Makefile.sphinx:31: *** only one `else' per conditional. Stop.
make: *** [help] Error 2
The first breakage was introduced by commit c8589d1e9e ("kbuild:
handle multi-objs dependency appropriately"). Since then (i.e. v3.18),
GNU Make 3.80 has not been able to compile the kernel, but nobody has
ever complained aboutt (or noticed) it.
Even GNU Make 3.81 is more than 10 years old. It would not hurt to
match the documentation with reality instead of fixing makefiles.

Commit 17a9be3174 ("initramfs: Always do fput() and load modules after
rootfs populate") introduced an error for the
CONFIG_BLK_DEV_RAM=y
case, because even though the code looks fine, the compiler really wants
a statement after a label, or you'll get complaints:
init/initramfs.c: In function 'populate_rootfs':
init/initramfs.c:644:2: error: label at end of compound statement
That commit moved the subsequent statements to outside the compound
statement, leaving the label without any associated statements.

* Region media error reporting: A libnvdimm region device is the parent
to one or more namespaces. To date, media errors have been reported via
the "badblocks" attribute attached to pmem block devices for namespaces
in "raw" or "memory" mode. Given that namespaces can be in "device-dax"
or "btt-sector" mode this new interface reports media errors
generically, i.e. independent of namespace modes or state. This
subsequently allows userspace tooling to craft "ACPI 6.1 Section
9.20.7.6 Function Index 4 - Clear Uncorrectable Error" requests and
submit them via the ioctl path for NVDIMM root bus devices.
* Introduce 'struct dax_device' and 'struct dax_operations': Prompted by
a request from Linus and feedback from Christoph this allows for dax
capable drivers to publish their own custom dax operations. This fixes
the broken assumption that all dax operations are related to a
persistent memory device, and makes it easier for other architectures
and platforms to add customized persistent memory support.
* 'libnvdimm' core updates: A new "deep_flush" sysfs attribute is
available for storage appliance applications to manually trigger memory
controllers to drain write-pending buffers that would otherwise be
flushed automatically by the platform ADR (asynchronous-DRAM-refresh)
mechanism at a power loss event. Support for "locked" DIMMs is included
to prevent namespaces from surfacing when the namespace label data area
is locked. Finally, fixes for various reported deadlocks and crashes,
also tagged for -stable.
* ACPI / nfit driver updates: General updates of the nfit driver to add
DSM command overrides, ACPI 6.1 health state flags support, DSM payload
debug available by default, and various fixes.

dax capable drivers to publish their own custom dax operations.
This fixes the broken assumption that all dax operations are
related to a persistent memory device, and makes it easier for
other architectures and platforms to add customized persistent
memory support.
- 'libnvdimm' core updates: A new "deep_flush" sysfs attribute is
available for storage appliance applications to manually trigger
memory controllers to drain write-pending buffers that would
otherwise be flushed automatically by the platform ADR
(asynchronous-DRAM-refresh) mechanism at a power loss event.
Support for "locked" DIMMs is included to prevent namespaces from
surfacing when the namespace label data area is locked. Finally,
fixes for various reported deadlocks and crashes, also tagged for
-stable.
- ACPI / nfit driver updates: General updates of the nfit driver to
add DSM command overrides, ACPI 6.1 health state flags support, DSM
payload debug available by default, and various fixes.

Here is the big staging tree update for 4.12-rc1. And it's a big one,
adding about 350k new lines of crap^Wcode, mostly all in a big dump of
media drivers from Intel. But there's other new drivers in here as
well, yet-another-wifi driver, new IIO drivers, and a new crypto
accelerator. We also deleted a bunch of stuff, mostly in patch
cleanups, but also the Android ION code has shrunk a lot, and the
Android low memory killer driver was finally deleted, much to the
celebration of the -mm developers.
All of these have been in linux-next with a few build issues that will
show up when you merge to your tree, I'll follow up with fixes for those
after this gets merged.

3. Andreas also cleaned up the rhashtable key ugliness Linus
pointed out during this cycle, following Linus's suggestions.
4. Andreas also wrote a patch to take advantage of his new
function rhashtable_lookup_get_insert_fast. This makes glock
lookup faster and more bullet-proof.
5. Andreas also wrote a patch to revert a patch in the evict
path that caused occasional deadlocks, and is no longer
needed.
6. Andrew Price wrote a patch to re-enable fallocate for the
rindex system file to enable gfs2_grow to grow properly on
secondary file system grow operations.
7. I wrote a patch to initialize an inode number field to make
certain kernel trace points more understandable.
8. I also wrote a patch that makes GFS2 file system "withdraw"
work more like it should by ignoring operations after a
withdraw that would formerly cause a BUG() and kernel panic.
9. I also reworked the entire truncate/delete algorithm,
scrapping the old recursive algorithm in favor of a new
non-recursive algorithm. This was done for performance:
This way, GFS2 no longer needs to lock multiple resource
groups while doing truncates and deletes of files that cross
multiple resource group boundaries, allowing for better
parallelism. It also solves a problem whereby deleting large
files would request a large chunk of kernel memory, which
resulted in a get_page_from_freelist warning.
10. Due to a regression found during testing, I added a new
patch to correct "GFS2: Prevent BUG from occurring when
normal Withdraws occur".

Merge tag 'initramfs-fix-4.12-rc1' of git://github.com/stffrdhrn/linux
Pull initramfs fix from Stafford Horne:
"This is a fix for an issue that has caused 4.11 to not boot on
OpenRISC. I should have caught this during the 4.11 cycle but I had
been busy on testing some other series of patches.
I would have considered pushing it though a different path but Al Viro
suggested submitting directly to you.
Also, its just one as I havent really got anything else ready on my
queue for 4.12.
Summary:
- Ensure fput() flush is done even for builtin initramfs"
* tag 'initramfs-fix-4.12-rc1' of git://github.com/stffrdhrn/linux:
initramfs: Always do fput() and load modules after rootfs populate
