The secondary CPU starts up in ARM mode. When the kernel is compiled in thumb2 mode we have to explicitly compile the secondary startup trampoline in ARM mode, otherwise the CPU will go to Nirvana.

From: Sven Eckelmann <sven@narfation.org>
commit c78296665c3d81f040117432ab9e1cb125521b0c upstream.
The encapsulated ethernet and VLAN header may be outside the received
ethernet frame. Thus the skb buffer size has to be checked before it can be
parsed to find out if it encapsulates another batman-adv packet.

commit 47325078f2a3e543150e7df967e45756b2fff7ec upstream.
The dummy component is reused for all cards so we special case and don't
bind it to any of them. This means that code like that displaying the
component widgets that tries to look at the card will crash. In the
future we will fix this by ensuring that the dummy component looks like
other components but that is invasive and so not suitable for a fix.
Instead add a special case check here.

4.2.8-ckt10 -stable review patch. If anyone has any objections, please let me know.
---8<------------------------------------------------------------
From: Imre Deak <imre.deak@intel.com>
commit dab9a2663f4e688106c041f7cd2797a721382f0a upstream.
During system resume we depended on pci_enable_device() also putting the
device into PCI D0 state. This won't work if the PCI device was already
enabled but still in D3 state. This is because pci_enable_device() is
refcounted and will not change the HW state if called with a non-zero
refcount. Leaving the device in D3 will make all subsequent device
accesses fail.
This didn't cause a problem most of the time, since we resumed with an
enable refcount of 0. But it fails at least after module reload because
after that we also happen to leak a PCI device enable reference: During
probing we call drm_get_pci_dev() which will enable the PCI device, but
during device removal drm_put_dev() won't disable it. This is a bug of
its own in DRM core, but without much harm as it only leaves the PCI
device enabled. Fixing it is also a bit more involved, due to DRM
mid-layering and because it affects non-i915 drivers too. The fix in
this patch is valid regardless of the problem in DRM core.
v2:
- Add a code comment about the relation of this fix to the freeze/thaw
vs. the suspend/resume phases. (Ville)
- Add a code comment about the inconsistent ordering of set power state
and device enable calls. (Chris)

From: Hariprasad S <hariprasad@chelsio.com>
commit 32cc92c7b5e52357a0a24010bae9eb257fa75d3e upstream.
For T4, kernel mode qps don't use the user doorbell. User mode qps during
flow control db ringing are forced into kernel, where user doorbell is
treated as kernel doorbell and proper bar2 offset in bar2 virtual space is
calculated, which incase of T4 is a bogus address, causing a kernel panic
due to illegal write during doorbell ringing.
In case of T4, kernel mode qp bar2 virtual address should be 0. Added T4
check during bar2 virtual address calculation to return 0. Fixed Bar2
range checks based on bar2 physical address.
The below oops will be fixed

Both of these drivers can return NOTIFY_BAD, but this terminates processing other callbacks that were registered later on the chain. Since the driver did nothing to log the error it seems wrong to prevent other interested parties from seeing it. E.g. neither of them had even bothered to check the type of the error to see if it was a memory error before the return NOTIFY_BAD.

| Message-ID | <rwZvu-3Ct-49@gated-at.bofh.it> |
| In reply to | #1397286 |
4.2.8-ckt10 -stable review patch. If anyone has any objections, please let me know.
---8<------------------------------------------------------------
From: Jason Baron <jbaron@akamai.com>
commit bc22af74f271ef76b2e6f72f3941f91f0da3f5f8 upstream.
Khugepaged attempts to raise min_free_kbytes if its set too low.
However, on boot khugepaged sets min_free_kbytes first from
subsys_initcall(), and then the mm 'core' over-rides min_free_kbytes
after from init_per_zone_wmark_min(), via a module_init() call.
Khugepaged used to use a late_initcall() to set min_free_kbytes (such
that it occurred after the core initialization), however this was
removed when the initialization of min_free_kbytes was integrated into
the starting of the khugepaged thread.
The fix here is simply to invoke the core initialization using a
core_initcall() instead of module_init(), such that the previous
initialization ordering is restored. I didn't restore the
late_initcall() since start_stop_khugepaged() already sets
min_free_kbytes via set_recommended_min_free_kbytes().
This was noticed when we had a number of page allocation failures when
moving a workload to a kernel with this new initialization ordering. On
an 8GB system this restores min_free_kbytes back to 67584 from 11365
when CONFIG_TRANSPARENT_HUGEPAGE=y is set and either
CONFIG_TRANSPARENT_HUGEPAGE_ALWAYS=y or
CONFIG_TRANSPARENT_HUGEPAGE_MADVISE=y.

From: Krzysztof Kozlowski <k.kozlowski@samsung.com>
commit a0a966b83873f33778710a4fc59240244b0734a5 upstream.
We want to skip reparenting a clock on turning on power domain, if we
do not have the parent yet. The parent is obtained when turning the
domain off. However due to a typo, the loop is continued on IS_ERR() of
clock being reparented, not on the IS_ERR() of the parent.
Theoretically this could lead to OOPS on first turn on of a power
domain, if there was no turn off before. Practically that should never
happen because all power domains are turned on by default (reset value,
bootloader does not turn off them usually) so the first action will be
always turn off.
Fixes: 29e5eea06bc1 ("ARM: EXYNOS: Get current parent clock for power domain on/off")

From: Anton Blanchard <anton@samba.org>
commit b4c112114aab9aff5ed4568ca5e662bb02cdfe74 upstream.
In create_zero_mask() we have:
addi %1,%2,-1
andc %1,%1,%2
popcntd %0,%1
using the "r" constraint for %2. r0 is a valid register in the "r" set,
but addi X,r0,X turns it into an li:
li r7,-1
andc r7,r7,r0
popcntd r4,r7
Fix this by using the "b" constraint, for which r0 is not a valid
register.
This was found with a kernel build using gcc trunk, narrowed down to
when -frename-registers was enabled at -O2. It is just luck however
that we aren't seeing this on older toolchains.
Thanks to Segher for working with me to find this issue.

4.2.8-ckt10 -stable review patch. If anyone has any objections, please let me know.

From: Wang YanQing <udknight@gmail.com>
commit c10fcb14c7afd6688c7b197a814358fecf244222 upstream.
The code for checking whether a BAR address range is valid will break
out of the loop when a start address of 0x0 is encountered.
This behaviour is wrong since by breaking out of the loop we may miss
the BAR that describes the EFI frame buffer in a later iteration.
Because of this bug I can't use video=efifb: boot parameter to get
efifb on my new ThinkPad E550 for my old linux system hard disk with
3.10 kernel. In 3.10, efifb is the only choice due to DRM/I915 not
supporting the GPU.
This patch also add a trivial optimization to break out after we find
the frame buffer address range without testing later BARs.

commit f0b22d1bb2a37a665a969e95785c75a4f49d1499 upstream.
Do not load one entry beyond the end of the syscall table when the
syscall number of a traced process equals to __NR_Linux_syscalls.
Similar bug with regular processes was fixed by commit 3bb457af4fa8
("[PARISC] Fix bug when syscall nr is __NR_Linux_syscalls").
This bug was found by strace test suite.

From: Vineet Gupta <vgupta@synopsys.com>
commit e5bc0478ab6cf565619224536d75ecb2aedca43b upstream.
While reviewing a different change to asm-generic/io.h Arnd spotted that
ARC ioread32 and ioread32be both of which come from asm-generic versions
are not symmetrical in terms of calling the io barriers.
generic ioread32 -> ARC readl() [ has barriers]
generic ioread32be -> __be32_to_cpu(__raw_readl()) [ lacks barriers]
While generic ioread32be is being remediated to call readl(), that involves
a swab32(), causing double swaps on ioread32be() on Big Endian systems.
So provide our versions of big endian IO accessors to ensure io barrier
calls while also keeping them optimal

4.2.8-ckt10 -stable review patch. If anyone has any objections, please let me know.
---8<------------------------------------------------------------
From: Howard Cochran <hcochran@kernelspring.com>
commit 74d369443325063a5f0260e63971decb950fd8fa upstream.
Commit 947e9762a8dd ("writeback: update wb_over_bg_thresh() to use
wb_domain aware operations") unintentionally changed this function's
meaning from "are there more dirty pages than the background writeback
threshold" to "are there more dirty pages than the writeback threshold".
The background writeback threshold is typically half of the writeback
threshold, so this had the effect of raising the number of dirty pages
required to cause a writeback worker to perform background writeout.
This can cause a very severe performance regression when a BDI uses
BDI_CAP_STRICTLIMIT because balance_dirty_pages() and the writeback worker
can now disagree on whether writeback should be initiated.
For example, in a system having 1GB of RAM, a single spinning disk, and a
"pass-through" FUSE filesystem mounted over the disk, application code
mmapped a 128MB file on the disk and was randomly dirtying pages in that
mapping.
Because FUSE uses strictlimit and has a default max_ratio of only 1%, in
balance_dirty_pages, thresh is ~200, bg_thresh is ~100, and the
dirty_freerun_ceiling is the average of those, ~150. So, it pauses the
dirtying processes when we have 151 dirty pages and wakes up a background
writeback worker. But the worker tests the wrong threshold (200 instead of
100), so it does not initiate writeback and just returns.
Thus, balance_dirty_pages keeps looping, sleeping and then waking up the
worker who will do nothing. It remains stuck in this state until the few
dirty pages that we have finally expire and we write them back for that
reason. Then the whole process repeats, resulting in near-zero throughput
through the FUSE BDI.
The fix is to call the parameterized variant of wb_calc_thresh, so that the
worker will do writeback if the bg_thresh is exceeded which was the
behavior before the referenced commit.

Without this there was a double free of the metadata,
which ended up freeing the fd table for me here, and taking
out the machine more often than not.
I reproduced with X.org + modesetting DDX + latest llvm/mesa,
also required using dri3.
