commit afae5ad78b342f401c28b0bb1adb3cd494cb125a
"net/fsl_pq_mdio: streamline probing of MDIO nodes"
added support for different types of MDIO devices:
1) Gianfar MDIO nodes that only map the MII registers
2) Gianfar MDIO nodes that map the full MDIO register set
3) eTSEC2 MDIO nodes (which map the full MDIO register set)
4) QE MDIO nodes (which map only the MII registers)
However, the implementation for types 1 and 4 would mistakenly assume
a mapping of the full MDIO register set, thereby computing the address
for the TBI register starting from the containing structure.
The TBI register would therefore be accessed at a wrong (much bigger)
address, not giving the expected result at all.
This patch restores the correct behavior we had prior to the above one.
The consequences of this bug are apparent when trying to access a PHY
with the same address as the value contained in the initial value of
the TBI register (normally 0); in that case you'll get answers from the
internal TBI device (even though MDIO/MDC pins are actually *also*
toggling on the physical bus!).
Beware that you also need to add a fake tbi node to your device tree
with an unused address.
Notice how this fix is related to commit
220669495bf8b68130a8218607147c7b74c28d2b
"powerpc: Add TBI PHY node to first MDIO bus"
which fixed the behavior in kernel 3.3, which was later broken by the
above commit on kernel 3.7.

When configuring the MDIO subsystem it is also necessary to configure
the TBI register. Make sure the TBI is contained within the mapped
register range in order to:
a) make sure the address is computed correctly
b) make users aware that we're actually accessing that register
In case of error, print a message but continue anyway.

Commit 7a5692e6e533 ("arch/powerpc: provide zero_bytemask() for

fine for the kernel build but missed the fact that we also use

Commit 63aa945b1013 ("memory: omap-gpmc: Add Kconfig option for debug")
added a debug option for GPMC, but somehow managed to keep it unselectable.
This probably happened because I had some uncommitted changes and the
GPMC option is selected in the platform specific Kconfig.
Let's also update the description a bit, it does not mention that
enabling the debug option also disables the reset of GPMC controller
during the init as pointed out by Uwe Kleine-König
<u.kleine-koenig@pengutronix.de> and Roger Quadros <rogerq@ti.com>.

LDO1 regulator (VDD_SD) is connected to SoC's vddshv8. vddshv8 needs to
be kept always powered (see commit 5a0f93c6576a ("ARM: dts: Add
am57xx-beagle-x15"), but at the moment VDD_SD is enabled/disabled
depending on whether an SD card is inserted or not.
This patch sets LDO1 regulator to always-on.
This patch has a side effect of fixing another issue, HDMI DDC not
working when SD card is not inserted:
Why this happens is that the tpd12s015 (HDMI level shifter/ESD
protection chip) has LS_OE GPIO input, which needs to be enabled for the
HDMI DDC to work. LS_OE comes from gpio6_28. The pin that provides
gpio6_28 is powered by vddshv8, and vddshv8 comes from VDD_SD.
So when SD card is not inserted, VDD_SD is disabled, and LS_OE stays
off.
The proper fix for the HDMI DDC issue would be to maybe have the pinctrl
framework manage the pin specific power.
Apparently this fixes also a third issue (copy paste from Kishon's
patch):
ldo1_reg in addition to being connected to the io lines is also
connected to the card detect line. On card removal, omap_hsmmc
driver does a regulator_disable causing card detect line to be
pulled down. This raises a card insertion interrupt and once the
MMC core detects there is no card inserted, it does a
regulator disable which again raises a card insertion interrupt.
This happens in a loop causing infinite MMC interrupts.

Compiling the nvme driver on 32-bit warns about a cast from a __u64
variable to a pointer:
drivers/block/nvme-core.c: In function 'nvme_submit_io':
drivers/block/nvme-core.c:1847:4: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
(void __user *)io.addr, length, NULL, 0);
The cast here is intentional and safe, so we can shut up the
gcc warning by adding an intermediate cast to 'uintptr_t'.
I had previously submitted a patch to fix this problem in the
nvme driver, but it was accepted on the same day that two new
warnings got added.
For clarification, I also change the third instance of this cast
to use uintptr_t instead of unsigned long now.

Commit df057cc7b4fa ("arm64: errata: add module build workaround for
erratum #843419") sets CFLAGS_MODULE to ensure that the large memory
model is used by the compiler when building kernel modules.
However, CFLAGS_MODULE is an environment variable and intended to be
overridden on the command line, which appears to be the case with the
Ubuntu kernel packaging system, so use KBUILD_CFLAGS_MODULE instead.

For memcg domains, the amount of available memory was calculated as
min(the amount currently in use + headroom according to memcg,
total clean memory)
This isn't quite correct as what should be capped by the amount of
clean memory is the headroom, not the sum of memory in use and
headroom. For example, if a memcg domain has a significant amount of
dirty memory, the above can lead to a value which is lower than the
current amount in use which doesn't make much sense. In most
circumstances, the above leads to a number which is somewhat but not
drastically lower.
As the amount of memory which can be readily allocated to the memcg
domain is capped by the amount of system-wide clean memory which is
not already assigned to the memcg itself, the number we want is
the amount currently in use +
min(headroom according to memcg, clean memory elsewhere in the system)
This patch updates mem_cgroup_wb_stats() to return the number of
filepages and headroom instead of the calculated available pages.
mdtc_cap_avail() is renamed to mdtc_calc_avail() and performs the
above calculation from file, headroom, dirty and globally clean pages.
v2: Dummy mem_cgroup_wb_stats() implementation wasn't updated leading
to build failure when !CGROUP_WRITEBACK. Fixed.

wb->memcg_completions
MDTC_INIT() is used to initialize dirty_throttle_control for memcg
domains. It used DTC_INIT_COMMON() to initialized mdtc->wb and
->wb_completions which is incorrect as DTC_INIT_COMMON() sets the
latter to wb->completions instead of wb->memcg_completions. This can
lead to wildly incorrect results when calculating the proportion of
dirty memory the memcg domain should get.
Remove DTC_INIT_COMMON() and update MDTC_INIT() to initialize
mdtc->wb_completions to wb->memcg_completions.

bdi_for_each_wb() is used in several places to wake up or issue
writeback work items to all wb's (bdi_writeback's) on a given bdi.
The iteration is performed by walking bdi->cgwb_tree; however, the
tree only indexes wb's which are currently active.
For example, when a memcg gets associated with a different blkcg, the
old wb is removed from the tree so that the new one can be indexed.
The old wb starts dying from then on but will linger till all its
inodes are drained. As these dying wb's may still host dirty inodes,
writeback operations which affect all wb's must include them.
bdi_for_each_wb() skipping dying wb's led to sync(2) missing and
failing to sync the inodes belonging to those wb's.
This patch adds a RCU protected @bdi->wb_list which lists all wb's
beloinging to that bdi. wb's are added on creation and removed on
release rather than on the start of destruction. bdi_for_each_wb()
usages are replaced with list_for_each[_continue]_rcu() iterations
over @bdi->wb_list and bdi_for_each_wb() and its helpers are removed.
v2: Updated as per Jan. last_wb ref leak in bdi_split_work_to_wbs()
fixed and unnecessary list head severing in cgwb_bdi_destroy()
removed.

Now that the NFS server advertises a maximum payload size of 1MB
for RPC/RDMA again, it crashes in svc_process_common() when NFS
client sends a 1MB NFS WRITE on an NFS/RDMA mount.
The server has set up a 259 element array of struct page pointers
in rq_pages[] for each incoming request. The last element of the
array is NULL.
When an incoming request has been completely received,
rdma_read_complete() attempts to set the starting page of the
incoming page vector:
rqstp->rq_arg.pages = &rqstp->rq_pages[head->hdr_count];
and the page to use for the reply:
rqstp->rq_respages = &rqstp->rq_arg.pages[page_no];
But the value of page_no has already accounted for head->hdr_count.
Thus rq_respages now points past the end of the incoming pages.
For NFS WRITE operations smaller than the maximum, this is harmless.
But when the NFS WRITE operation is as large as the server's max
payload size, rq_respages now points at the last entry in rq_pages,
which is NULL.

In this change, we resolve all of the above by ignoring any checksum

This is a clone of commit 2ab957492d13b ("ip_forward: Drop frames with
attached skb->sk") for ipv6.
This commit has exactly the same reasons as the above mentioned commit,
namely to prevent panics during netfilter reload or a misconfigured stack.

Configuring 4-tuple RSS hsahing for UDP
[E.g., by using `ethtool -N <interface> rx-flow-hash udp4 sdfn']
on a 57710/57711 adapter would cause it to assert as HW does not
support such a configuration.

When calculating the shift needed in order to access a bit array element
in a byte, we should multiply the index by the element size and not
assume it is fixed at 2-bits.

Similar to commit c0afd9ce4d6a ("fq_codel: fix return value of fq_codel_drop()")
->drop() is supposed to return the number of bytes it dropped,
but hhf_drop () returns the id of the bucket where it drops
a packet from.
