"The megaraid_sas patch in here fixes a major regression in the last
fix set that made all megaraid_sas cards unusable. It turns out no-one
had actually tested such an "obvious" fix, sigh. The fix for the fix
has been tested ...
The next most serious is the vmw_pvscsi abort problem which basically
means that aborts don't work on the vmware paravirt devices and error
handling always escalates to reset.
The rest are an assortment of missed reference counting in certain

The DVB binding schema at the DVB core assumes that the frontend is a
separate driver. Faling to do that causes OOPS when the module is
removed, as it tries to do a symbol_put_addr on an internal symbol,

The device's neighbour table is periodically dumped in order to update
the kernel about active neighbours. A single dump session may span
multiple queries, until the response carries less records than requested
or when a record (can contain up to four neighbour entries) is not full.
Current code stops the session when the number of returned records is
zero, which can result in infinite loop in case of high packet rate.
Fix this by stopping the session according to the above logic.

When binding port to a newly created span entry, its refcount is
initialized to zero even though it has a bound port. That leads
to unexpected behaviour when the user tries to delete that port
from the span entry.
Fix this by initializing the reference count to 1.
Also add a warning to put function.

If the physical link is down and the VF virtual link is set to "enable",
the current code does not always work. If the link is down but the
cable is attached, the firmware returns LINK_SIGNAL instead of
NO_LINK. The current code is treating LINK_SIGNAL as link up.
The fix is to treat link as down when the link_status != LINK.

This is a work around for a bug with LSI Fusion MPT SAS2 when perfoming
secure erase. Due to the very long time the operation takes, commands
issued during the erase will time out and will trigger execution of the
abort hook. Even though the abort hook is called for the specific
command which timed out, this leads to entire device halt
(scsi_state terminated) and premature termination of the secure erase.
Set device state to busy while ATA passthrough commands are in progress.

The function's behaviour was changed in 90844f00049e, without changing
its signature, causing people to keep using it the old way without
realising they were now leaking memory.
Rob Clark also noticed it was also allocating GFP_KERNEL memory in
atomic contexts, breaking them.
Instead of having to allocate GFP_ATOMIC memory and fixing the callers
to make them cleanup the memory afterwards, let's change the function's
signature by having the caller take care of the memory and passing it to
the function.
The new parameter is a single-field struct in order to enforce the size
of its buffer and help callers to correctly manage their memory.

The ns->lba_shift assumes its value to be the logarithmic of the
LA size. A previous patch duplicated the lba_shift calculation into
lightnvm. It prematurely also subtracted a 512byte shift, which commonly
is applied per-command. The 512byte shift being subtracted twice led to
data loss when restoring the logical to physical mapping table from
device and when issuing I/O commands using rrpc.
Fix offset by removing the 512byte shift subtraction when calculating
lba_shift.

Merge fixes for -Wmaybe-uninitialized from Arnd Bergmann:
"It took a while for some patches to make it into mainline through
maintainer trees, but the 28-patch series is now reduced to 10, with
one tiny patch added at the end.
Aside from patches that are no longer required, I did these changes
compared to version 1:
- Dropped "iio: maxim_thermocouple: detect invalid storage size in
read()", which is currently in linux-next as commit 32cb7d27e65d.
This is the only remaining warning I see for a couple of corner
cases (kbuild bot reports it on blackfin, kernelci bot and arm-soc
bot both report it on arm64)
- Dropped "brcmfmac: avoid maybe-uninitialized warning in
brcmf_cfg80211_start_ap", which is currently in net/master merge
pending.
- Dropped two x86 patches, "x86: math-emu: possible uninitialized
variable use" and "x86: mark target address as output in 'insb'
asm" as they do not seem to trigger for a default build, and I got
no feedback on them. Both of these are ancient issues and seem
harmless, I will send them again to the x86 maintainers once the
rest is merged.
- Dropped "rbd: false-postive gcc-4.9 -Wmaybe-uninitialized" based on
feedback from Ilya Dryomov, who already has a different fix queued
up for v4.10. The kbuild bot reports this as a warning for xtensa.
- Replaced "crypto: aesni: avoid -Wmaybe-uninitialized warning" with
a simpler patch, this one always triggers but my first solution
would not be safe for linux-4.9 any more at this point. I'll follow
up with the larger patch as a cleanup for 4.10.
- Replaced "dib0700: fix nec repeat handling" with a better one,
contributed by Sean Young"
* -Wmaybe-uninitialized fixes:
Kbuild: enable -Wmaybe-uninitialized warnings by default
pcmcia: fix return value of soc_pcmcia_regulator_set
infiniband: shut up a maybe-uninitialized warning
crypto: aesni: shut up -Wmaybe-uninitialized warning
rc: print correct variable for z8f0811
dib0700: fix nec repeat handling
s390: pci: don't print uninitialized data for debugging
nios2: fix timer initcall return value
x86: apm: avoid uninitialized data
NFSv4.1: work around -Wmaybe-uninitialized warning
Kbuild: enable -Wmaybe-uninitialized warning for "make W=1"

The newly introduced soc_pcmcia_regulator_set() function sometimes
returns without setting its return code, as shown by this warning:
drivers/pcmcia/soc_common.c: In function 'soc_pcmcia_regulator_set':
drivers/pcmcia/soc_common.c:112:5: error: 'ret' may be used uninitialized in this function [-Werror=maybe-uninitialized]
This changes it to propagate the regulator_disable() result instead.

Some configurations produce this harmless warning when built with gcc
-Wmaybe-uninitialized:
infiniband/core/cma.c: In function 'cma_get_net_dev':
infiniband/core/cma.c:1242:12: warning: 'src_addr_storage.sin_addr.s_addr' may be used uninitialized in this function [-Wmaybe-uninitialized]
I previously reported this for the powerpc64 defconfig, but have now
reproduced the same thing for x86 as well, using gcc-5 or higher.
The code looks correct to me, and this change just rearranges it by
making sure we alway initialize the entire address structure to make the
warning disappear. My first approach added an initialization at the
time of the declaration, which Doug commented may be too costly, so I
hope this version doesn't add overhead.

A recent rework accidentally left a debugging printk untouched while

drivers/media/i2c/ir-kbd-i2c.c:62:2: error: 'toggle' may be used uninitialized in this function [-Werror=maybe-uninitialized]

When receiving a nec repeat, ensure the correct scancode is repeated
rather than a random value from the stack. This removes the need for
the bogus uninitialized_var() and also fixes the warnings:
drivers/media/usb/dvb-usb/dib0700_core.c: In function ‘dib0700_rc_urb_completion’:
drivers/media/usb/dvb-usb/dib0700_core.c:679: warning: ‘protocol’ may be used uninitialized in this function
[sean addon: So after writing the patch and submitting it, I've bought the
hardware on ebay. Without this patch you get random scancodes
on nec repeats, which the patch indeed fixes.]

When we release the shmem backing storage, we make sure that the pages
are coherent with the cpu cache. However, our clflush routine was
skipping the flush as the object had no pages at release time. Fix this by

In order to walk the list of all timelines, we currently require the
struct_mutex. We are sometimes called prior to the struct_mutex being
taken by the caller (i.e !I915_WAIT_LOCKED) in which case we can only
trust the global execution timelines (as these are owned by the device).
This means in the unlocked phase we can only wait upon the currently
executing requests and not all queued.

This reverts commit 05fd007e4629 ("console: don't prefer first
registered if DT specifies stdout-path").
The reverted commit changes existing behavior on which many ARM boards
rely. Many ARM small-board-computers, like e.g. the Raspberry Pi have
both a video output and a serial console. Depending on whether the user
is using the device as a more regular computer; or as a headless device
we need to have the console on either one or the other.
Many users rely on the kernel behavior of the console being present on
both outputs, before the reverted commit the console setup with no
console= kernel arguments on an ARM board which sets stdout-path in dt
would look like this:
[root@localhost ~]# cat /proc/consoles
ttyS0 -W- (EC p a) 4:64
tty0 -WU (E p ) 4:1
Where as after the reverted commit, it looks like this:
[root@localhost ~]# cat /proc/consoles
ttyS0 -W- (EC p a) 4:64
This commit reverts commit 05fd007e4629 ("console: don't prefer first
registered if DT specifies stdout-path") restoring the original
behavior.
Fixes: 05fd007e4629 ("console: don't prefer first registered if DT specifies stdout-path")
