[ Upstream commit 34c55cf2fc75f8bf6ba87df321038c064cf2d426 ]
Currently dp83867 driver returns error if phy interface type
PHY_INTERFACE_MODE_RGMII_RXID is used to set the rx only internal
delay. Similarly issue happens for PHY_INTERFACE_MODE_RGMII_TXID.
Fix this by checking also the interface type if a particular delay
value is missing in the phy dt bindings. Also update the DT document
accordingly.

[ Upstream commit 61976fff20f92aceecc3670f6168bfc57a79e047 ]
When the binding was defined, I was not aware that mt2701 was an earlier
version of the SoC. For sake of consistency, the ethernet driver should
use mt2701 inside the compat string as this is the earliest SoC with the
ethernet core.
The ethernet driver is currently of no real use until we finish and
upstream the DSA driver. There are no users of this binding yet. It should
be safe to fix this now before it is too late and we need to provide
backward compatibility for the mt7623-eth compat string.

[ Upstream commit 308d3165d8b2b98d3dc3d97d6662062735daea67 ]
The patches regarding eee-broken-modes was merged before all people
involved could find an agreement on the best way to move forward.
While we agreed on having a DT property to mark particular modes as broken,
the value used for eee-broken-modes mapped the phy register in very direct
way. Because of this, the concern is that it could be used to implement
configuration policies instead of describing a broken HW.
In the end, having a boolean property for each mode seems to be preferred
over one bit field value mapping the register (too) directly.

commit 1be7107fbe18eed3e319a6c3e83c78254b693acb upstream.
Stack guard page is a useful feature to reduce a risk of stack smashing
into a different mapping. We have been using a single page gap which
is sufficient to prevent having stack adjacent to a different mapping.
But this seems to be insufficient in the light of the stack usage in
userspace. E.g. glibc uses as large as 64kB alloca() in many commonly
used functions. Others use constructs liks gid_t buffer[NGROUPS_MAX]
which is 256kB or stack strings with MAX_ARG_STRLEN.
This will become especially dangerous for suid binaries and the default
no limit for the stack size limit because those applications can be
tricked to consume a large portion of the stack and a single glibc call
could jump over the guard page. These attacks are not theoretical,
unfortunatelly.
Make those attacks less probable by increasing the stack guard gap
to 1MB (on systems with 4k pages; but make it depend on the page size
because systems with larger base pages might cap stack allocations in
the PAGE_SIZE units) which should cover larger alloca() and VLA stack
allocations. It is obviously not a full fix because the problem is
somehow inherent, but it should reduce attack space a lot.
One could argue that the gap size should be configurable from userspace,
but that can be done later when somebody finds that the new 1MB is wrong
for some special case applications. For now, add a kernel command line
option (stack_guard_gap) to specify the stack gap size (in page units).
Implementation wise, first delete all the old code for stack guard page:
because although we could get away with accounting one extra page in a
stack vma, accounting a larger gap can break userspace - case in point,
a program run with "ulimit -S -v 20000" failed when the 1MB gap was
counted for RLIMIT_AS; similar problems could come with RLIMIT_MLOCK
and strict non-overcommit mode.
Instead of keeping gap inside the stack vma, maintain the stack guard
gap as a gap between vmas: using vm_start_gap() in place of vm_start
(or vm_end_gap() in place of vm_end if VM_GROWSUP) in just those few
places which need to respect the gap - mainly arch_get_unmapped_area(),
and and the vma tree's subtree_gap support for that.

commit f0e421b1bf7af97f026e1bb8bfe4c5a7a8c08f42 upstream.
Some kernel features don't currently work if a task puts a non-zero
address tag in its stack pointer, frame pointer, or frame record entries
(FP, LR).
For example, with a tagged stack pointer, the kernel can't deliver
signals to the process, and the task is killed instead. As another
example, with a tagged frame pointer or frame records, perf fails to
generate call graphs or resolve symbols.
For now, just document these limitations, instead of finding and fixing
everything that doesn't work, as it's not known if anyone needs to use
tags in these places anyway.
In addition, as requested by Dave Martin, generalize the limitations
into a general kernel address tag policy, and refactor
tagged-pointers.txt to include it.
Fixes: d50240a5f6ce ("arm64: mm: permit use of tagged pointers at EL0")

[ Upstream commit 0b445549ea6f91ffea78a976fe89b932db6e077a ]
In soft (no-reboot) mode, the driver self-pings watchdog upon expiration
of an interrupt. However the interrupt itself was not cleared thus on
first hit, the system enters infinite interrupt handling loop.
On Odroid U3 (Exynos4412), when booted with s3c2410_wdt.soft_noboot=1
argument the console is flooded:
# killall -9 watchdog
[ 60.523760] s3c2410-wdt 10060000.watchdog: watchdog timer expired (irq)
[ 60.536744] s3c2410-wdt 10060000.watchdog: watchdog timer expired (irq)
Fix this by writing something to the WTCLRINT register to clear the
interrupt. The register WTCLRINT however appeared in S3C6410 so a new
watchdog quirk and flavor are needed.

[ Upstream commit 9c4aa1eecb48cfac18ed5e3aca9d9ae58fbafc11 ]
Sometimes, the users may require a quirk to be provided from ACPI subsystem
core to prevent a GPE from flooding.
Normally, if a GPE cannot be dispatched, ACPICA core automatically prevents
the GPE from firing. But there are cases the GPE is dispatched by _Lxx/_Exx
provided via AML table, and OSPM is lacking of the knowledge to get
_Lxx/_Exx correctly executed to handle the GPE, thus the GPE flooding may
still occur.
The existing quirk mechanism can be enabled/disabled using the following
commands to prevent such kind of GPE flooding during runtime:
# echo mask > /sys/firmware/acpi/interrupts/gpe00
# echo unmask > /sys/firmware/acpi/interrupts/gpe00
To avoid GPE flooding during boot, we need a boot stage mechanism.
This patch provides such a boot stage quirk mechanism to stop this kind of
GPE flooding. This patch doesn't fix any feature gap but since the new
feature gaps could be found in the future endlessly, and can disappear if
the feature gaps are filled, providing a boot parameter rather than a DMI
table should suffice.

[ Upstream commit d8ec7595a013237f82d965dcf981571aeb41855b ]
The ARM specifies that the system counter "must be implemented in an
always-on power domain," and so we try to use the counter as a source of
timekeeping across suspend/resume. Unfortunately, some SoCs (e.g.,
Rockchip's RK3399) do not keep the counter ticking properly when
switched from their high-power clock to the lower-power clock used in
system suspend. Support this quirk by adding a new device tree property.

commit 49c440e87cd6f547f93d0dc53571ae0e11d9ec8f upstream.
The A31's display pipeline has 2 frontends, 2 backends, and 2 TCONs. It
also has new display enhancement blocks, such as the DRC (Dynamic Range
Controller), the DEU (Display Enhancement Unit), and the CMU (Color
Management Unit). It supports HDMI, MIPI DSI, and 2 LCD/LVDS channels.
The A31s display pipeline is almost the same, just without MIPI DSI.
Only the TCON seems to be different, due to the missing mux for MIPI
DSI.
Add compatible strings for both of them.

commit 90922a2d03d84de36bf8a9979d62580102f31a92 upstream.
On Qualcomm Datacenter Technologies QDF2400 SoCs, the ITS hardware
implementation uses 16Bytes for Interrupt Translation Entry (ITE),
but reports an incorrect value of 8Bytes in GITS_TYPER.ITTE_size.
It might cause kernel memory corruption depending on the number
of MSI(x) that are configured and the amount of memory that has
been allocated for ITEs in its_create_device().
This patch fixes the potential memory corruption by setting the
correct ITE size to 16Bytes.

commit 47512cfd0d7a8bd6ab71d01cd89fca19eb2093eb upstream.
The goldfish platform code registers the platform device unconditionally
which causes havoc in several ways if the goldfish_pdev_bus driver is
enabled:
- Access to the hardcoded physical memory region, which is either not
available or contains stuff which is completely unrelated.
- Prevents that the interrupt of the serial port can be requested
- In case of a spurious interrupt it goes into a infinite loop in the
interrupt handler of the pdev_bus driver (which needs to be fixed
seperately).
Add a 'goldfish' command line option to make the registration opt-in when
the platform is compiled in.
I'm seriously grumpy about this engineering trainwreck, which has seven
SOBs from Intel developers for 50 lines of code. And none of them figured
out that this is broken. Impressive fail!

commit 0d808df06a44200f52262b6eb72bcb6042f5a7c5 upstream.
When switching from/to a guest that has a transaction in progress,
we need to save/restore the checkpointed register state. Although
XER is part of the CPU state that gets checkpointed, the code that
does this saving and restoring doesn't save/restore XER.
This fixes it by saving and restoring the XER. To allow userspace
to read/write the checkpointed XER value, we also add a new ONE_REG
specifier.
The visible effect of this bug is that the guest may see its XER
value being corrupted when it uses transactions.

====================
Netfilter fixes for net
This is a large batch of Netfilter fixes for net, they are:
1) Three patches to fix NAT conversion to rhashtable: Switch to rhlist
structure that allows to have several objects with the same key.
Moreover, fix wrong comparison logic in nf_nat_bysource_cmp() as this is
expecting a return value similar to memcmp(). Change location of
the nat_bysource field in the nf_conn structure to avoid zeroing
this as it breaks interaction with SLAB_DESTROY_BY_RCU and lead us
to crashes. From Florian Westphal.
2) Don't allow malformed fragments go through in IPv6, drop them,
otherwise we hit GPF, patch from Florian Westphal.
3) Fix crash if attributes are missing in nft_range, from Liping Zhang.
4) Fix arptables 32-bits userspace 64-bits kernel compat, from Hongxu Jia.
5) Two patches from David Ahern to fix netfilter interaction with vrf.
From David Ahern.
6) Fix element timeout calculation in nf_tables, we take milliseconds
from userspace, but we use jiffies from kernelspace. Patch from
Anders K. Pedersen.
7) Missing validation length netlink attribute for nft_hash, from
Laura Garcia.
8) Fix nf_conntrack_helper documentation, we don't default to off
anymore for a bit of time so let's get this in sync with the code.
I know is late but I think these are important, specifically the NAT
bits, as they are mostly addressing fallout from recent changes. I also
read there are chances to have -rc8, if that is the case, that would
also give us a bit more time to test this.

RGMII requires special RX and/or TX delays depending on the actual
hardware circuit/wiring. These delays can be added by the MAC, the PHY
or the designer of the circuit (the latter means that no delay has to
be added by PHY or MAC).
There are 4 RGMII phy-modes used describe where a delay should be
applied:
- rgmii: the RX and TX delays are either added by the MAC (where the
exact delay is typically configurable, and can be turned off when no
extra delay is needed) or not needed at all (because the hardware
wiring adds the delay already). The PHY should neither add the RX nor
TX delay in this case.
- rgmii-rxid: configures the PHY to enable the RX delay. The MAC should
not add the RX delay in this case.
- rgmii-txid: configures the PHY to enable the TX delay. The MAC should
not add the TX delay in this case.
- rgmii-id: combines rgmii-rxid and rgmii-txid and thus configures the
PHY to enable the RX and TX delays. The MAC should neither add the RX
nor TX delay in this case.
Document these cases in the ethernet.txt documentation to make it clear
when to use each mode.
If applied incorrectly one might end up with MAC and PHY both enabling
for example the TX delay, which breaks ethernet TX traffic on 1000Mbit/s
links.

Pull KVM fixes from Radim Krčmář:
"ARM:
- Fix handling of the 32bit cycle counter

- Fix a race leading to double unregistering of user notifiers
- Amend oversight in kvm_arch_set_irq that turned Hyper-V code dead
- Use SRCU around kvm_lapic_set_vapic_addr
- Avoid recursive flushing of asynchronous page faults
- Do not rely on deferred update in KVM_GET_CLOCK, which fixes #GP
- Let userspace know that KVM_GET_CLOCK is useful with master clock;

didn't provide means to let guests take advantage of it"

Userspace can read the exact value of kvmclock by reading the TSC
and fetching the timekeeping parameters out of guest memory. This
however is brittle and not necessary anymore with KVM 4.11. Provide
a mechanism that lets userspace know if the new KVM_GET_CLOCK
semantics are in effect, and---since we are at it---if the clock
is stable across all VCPUs.

git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes
Fixes for omaps for v4.9-rc cycle. Except for the omap3 fix for the SoC
features printed, all these are quite trivial and tiny. The omap5 jack
detection and gpadc patches are not strictly fixes, but I wanted to get
binding document typo fixed before it pops up on other boards. The
gpadc one liner was in the same series and I applied and pushed it out
already before noticing it could have waited. The list of changes is:
- Fix omap3 SoC features printed
- Make sure OMAP_INTERCONNECT is selected for am43xx only configurations
- Add missing memory node for torpedo
- Initialize uart4_mask properly to avoid writing garbage to PRM registers
- Fix NULL pointer dereference for omap4 volt_data
- Add alias for omap5 gpadc needed by iio drivers
- Enable omap5 jack headset jack detection and fix it's binding typo
- Add missing memory node for logicpd-som-lv

The Aspeed SoCs have two BT interfaces : one is IPMI compliant and the
other is H8S/2168 compliant.
The current ipmi/bt-bmc driver implements the IPMI version and we
should reflect its nature in the compatible node name using
'aspeed,ast2400-ibt-bmc' instead of 'aspeed,ast2400-bt-bmc'. The
latter should be used for a H8S interface driver if it is implemented
one day.

pm_rst, aclk_rst, pclk_rst was controlled by ROM code so the software
wasn't needed to control it again in theory. But it didn't work properly,
so we do need to do it again and add enough delay between the assert of
pm_rst and the deassert of pm_rst. The Soc intergrated with this
controller, rk3399, is still under MP test internally, so the backward
compatibility won't be a big deal.
