commit 67870eb120 upstream.
In banked-sr.c, we use a top-level '__asm__(".arch_extension virt")'
statement to allow compilation of a multi-CPU kernel for ARMv6
and older ARMv7-A that don't normally support access to the banked
registers.
This is considered to be a programming error by the gcc developers
and will no longer work in gcc-8, where we now get a build error:
/tmp/cc4Qy7GR.s:34: Error: Banked registers are not available with this architecture. -- `mrs r3,SP_usr'

/tmp/cc4Qy7GR.s:76: Error: Banked registers are not available with this architecture. -- `mrs r3,SP_abt'
Passign the '-march-armv7ve' flag to gcc works, and is ok here, because
we know the functions won't ever be called on pre-ARMv7VE machines.
Unfortunately, older compiler versions (4.8 and earlier) do not understand
that flag, so we still need to keep the asm around.
Backporting to stable kernels (4.6+) is needed to allow those to be built
with future compilers as well.

commit 8337d08350 upstream.
A section type mismatch warning shows up when building with LTO,
since orion_ge00_mvmdio_bus_name was put in __initconst but not marked
const itself:
include/linux/of.h: In function 'spear_setup_of_timer':
arch/arm/mach-spear/time.c:207:34: error: 'timer_of_match' causes a section type conflict with 'orion_ge00_mvmdio_bus_name'

static __initconst const char *orion_ge00_mvmdio_bus_name = "orion-mii";
^
As pointed out by Andrew Lunn, it should in fact be 'const' but not
'__initconst' because the string is never copied but may be accessed
after the init sections are freed. To fix that, I get rid of the
extra symbol and rewrite the initialization in a simpler way that
assigns both the bus_id and modalias statically.
I spotted another theoretical bug in the same place, where d->netdev[i]
may be an out of bounds access, this can be fixed by moving the device
assignment into the loop.

[ Upstream commit cf87634c8b ]
There's been a reproducable USB OHCI/EHCI cpuidle related hang on omap4
for a while that happens after about 20 - 40 minutes on an idle system
with some data feeding device being connected, like a USB GPS device or
a cellular modem.
This issue happens in cpuidle states C2 and C3 and does not happen if
cpuidle is limited to C1 state only. The symptoms are that the whole
system hangs and never wakes up from idle, and if a watchdog is
configured the system reboots after a while.
Turns out that OHCI/EHCI devices on omap4 are trying to use the GIC
interrupt controller directly as a parent instead of the WUGEN. We
need to pass the interrupts through WUGEN to GIC to provide the wakeup
events for the processor.
Let's fix the issue by removing the gic interrupt-parent and use the
default interrupt-parent wakeupgen instead. Note that omap5.dtsi had
this already fixes earlier by commit 7136d457f3 ("ARM: omap: convert
wakeupgen to stacked domains") but we somehow missed omap4 at that
point.

remove the generic am33xx_pwrdm_read_prev_pwrst hook which wrongly

Reading the reserved bits leads to wrongly interpreting the low

[ Upstream commit d09220a887 ]
With the CMA changes from Joonsoo Kim <iamjoonsoo.kim@lge.com>, it
was noticed that n900 stopped booting. After investigating it turned
out that n900 save_secure_ram_context does some whacky virtual to
physical address translation for the SRAM data address.
As we now only have minimal parts of omap3 idle code copied to SRAM,
running save_secure_ram_context() in SRAM is not needed. It only gets
called on PM init. And it seems there's no need to ever call this from
SRAM idle code.
So let's just keep save_secure_ram_context() in DDR, and pass it the
physical address of the parameters. We can do everything else in
omap-secure.c like we already do for other secure code.
And since we don't have any documentation, I still have no clue what
the values for 0, 1 and 1 for the parameters might be. If somebody has
figured it out, please do send a patch to add some comments.

Patch series "kmemcheck: kill kmemcheck", v2.
As discussed at LSF/MM, kill kmemcheck.
KASan is a replacement that is able to work without the limitation of
kmemcheck (single CPU, slow). KASan is already upstream.
We are also not aware of any users of kmemcheck (or users who don't
consider KASan as a suitable replacement).
The only objection was that since KASAN wasn't supported by all GCC
versions provided by distros at that time we should hold off for 2
years, and try again.
Now that 2 years have passed, and all distros provide gcc that supports
KASAN, kill kmemcheck again for the very same reasons.
This patch (of 4):

arch/arm/boot/dts/ste-nomadik-nhk15.dtb: Warning (interrupts_property): Missing interrupt-parent for /amba/clcd@10120000
I looked up the old board files and found that this interrupt has
the same irqchip as all the other on-chip device, it just needs one
extra line.

commit ca32e0c4bf upstream.
dtc warns about obviously incorrect GPIO numbers for the audio codec
on both lpc32xx boards:

It looks like the nodes are written for a different binding that combines
the GPIO number into a single number rather than a bank/number pair.
I found the right numbers on stackexchange.com, so this patch fixes
the warning and has a reasonable chance of getting things to actually
work.

commit 20e8175d24 upstream.
KVM doesn't follow the SMCCC when it comes to unimplemented calls,
and inject an UNDEF instead of returning an error. Since firmware
calls are now used for security mitigation, they are becoming more
common, and the undef is counter productive.
Instead, let's follow the SMCCC which states that -1 must be returned
to the caller when getting an unknown function number.

commit a208fa8f33 upstream.
We need to consistently enforce that keyed hashes cannot be used without
setting the key. To do this we need a reliable way to determine whether
a given hash algorithm is keyed or not. AF_ALG currently does this by
checking for the presence of a ->setkey() method. However, this is
actually slightly broken because the CRC-32 algorithms implement
->setkey() but can also be used without a key. (The CRC-32 "key" is not
actually a cryptographic key but rather represents the initial state.
If not overridden, then a default initial state is used.)
Prepare to fix this by introducing a flag CRYPTO_ALG_OPTIONAL_KEY which
indicates that the algorithm has a ->setkey() method, but it is not
required to be called. Then set it on all the CRC-32 algorithms.
The same also applies to the Adler-32 implementation in Lustre.
Also, the cryptd and mcryptd templates have to pass through the flag
from their underlying algorithm.

Commit 6167ec5c91 upstream.
A new feature of SMCCC 1.1 is that it offers firmware-based CPU
workarounds. In particular, SMCCC_ARCH_WORKAROUND_1 provides
BP hardening for CVE-2017-5715.
If the host has some mitigation for this issue, report that
we deal with it using SMCCC_ARCH_WORKAROUND_1, as we apply the
host workaround on every guest exit.

add gitignore patterns per directory. Since there are no source files
that end with .dtb or .dtb.S, we can ignore the patterns globally.

[ Upstream commit 5f1aa51c7a ]
Booting a kernel results in the kernel warning us about the following
PPI interrupts configuration:
[ 0.105127] smp: Bringing up secondary CPUs ...
[ 0.110545] GIC: PPI11 is secure or misconfigured
[ 0.110551] GIC: PPI13 is secure or misconfigured
Fix this by using the appropriate edge configuration for PPI11 and
PPI13, this is similar to what was fixed for Northstar (BCM5301X) in
commit 0e34079cd1 ("ARM: dts: BCM5301X: Correct GIC_PPI interrupt
flags").

When an eBPF program tail-calls another eBPF program, it enters it after
the prologue to avoid having complex stack manipulations. This can lead
to kernel oopses, and similar.
Resolve this by always using a fixed stack layout, a CPU register frame
pointer, and using this when reloading registers before returning.
