[ Upstream commit 33d0d843872c5ddbe28457a92fc6f2487315fb9f ]
The SPI chip selects are represented as:
cs-gpios = <&gpio4 11 GPIO_ACTIVE_LOW>, <&gpio4 13 GPIO_ACTIVE_LOW>;
, which means that they are used in GPIO function instead of native
SPI mode.
Fix the IOMUX for the chip select 1 to use GPIO4_13 instead of
the native CSPI_SSI function.

[ Upstream commit 57dbe558457bf4042169bc1f334e3b53a8480a1c ]
The Ethernet PHY on the Bananapi M3 and Cubietruck Plus have the RX
and TX delays enabled on the PHY, using pull-ups on the RXDLY and
TXDLY pins.
Fix the phy-mode description to correct reflect this so that the
implementation doesn't reconfigure the delays incorrectly. This
happened with commit bbc4d71d6354 ("net: phy: realtek: fix rtl8211e
rx/tx delay config").

[ Upstream commit 8d80e2f00a42ef10b54e1b2d9e97314f8fd046c0 ]
This reverts commit 75ee680cbd2e4d0156b94f9fec50076361ab12f2.
Turns out the activity and link LEDs on the RJ45 port are active low,
just like on the Orange Pi PC.
Revert the commit that says otherwise.

[ Upstream commit 9fa2e7af3d53a4b769136eccc32c02e128a4ee51 ]
Setting both CONFIG_KPROBES=y and CONFIG_FORTIFY_SOURCE=y on ARM leads
to a panic in memcpy() when injecting a kprobe despite the fixes found
in commit e46daee53bb5 ("ARM: 8806/1: kprobes: Fix false positive with
FORTIFY_SOURCE") and commit 0ac569bf6a79 ("ARM: 8834/1: Fix: kprobes:
optimized kprobes illegal instruction").
arch/arm/include/asm/kprobes.h effectively declares
the target type of the optprobe_template_entry assembly label as a u32
which leads memcpy()'s __builtin_object_size() call to determine that
the pointed-to object is of size four. However, the symbol is used as a handle
for the optimised probe assembly template that is at least 96 bytes in size.
The symbol's use despite its type blows up the memcpy() in ARM's
arch_prepare_optimized_kprobe() with a false-positive fortify_panic() when it
should instead copy the optimised probe template into place:
```

Commit f6361c6b3880 ("ARM: S3C24XX: remove separate restart code")
removed usage of the watchdog reset platform code in favor of the
Samsung SoC watchdog driver. However the latter was not selected thus
S3C24xx platforms lost reset abilities.

[ Upstream commit 19d3e9a0bdd57b90175f30390edeb06851f5f9f3 ]
We currently have a different clock rate for droid4 compared to the
stock v3.0.8 based Android Linux kernel:
# cat /sys/kernel/debug/clk/dpll_*_m7x2_ck/clk_rate
266666667
307200000
# cat /sys/kernel/debug/clk/l3_gfx_cm:clk:0000:0/clk_rate
307200000
Let's fix this by configuring sgx to use 153.6 MHz instead of 307.2 MHz.
Looks like also at least duover needs this change to avoid hangs, so
let's apply it for all 4430.
This helps a bit with thermal issues that seem to be related to memory
corruption when using sgx. It seems that other driver related issues
still remain though.

The L310_PREFETCH_CTRL register bits 28 and 29 to enable data and
instruction prefetch respectively can also be accessed via the

later on. For this reason, set these bits in both registers during

The commit fe00e50b2db8 ("ARM: 8858/1: vdso: use $(LD) instead of $(CC)
to link VDSO") removed the passing of CFLAGS, since ld doesn't take
those directly. However, prior, big-endian ARM was relying on gcc to
translate its -mbe8 option into ld's --be8 option. Lacking this, ld
generated be32 code, making the VDSO generate SIGILL when called by
userspace.
This commit passes --be8 if CONFIG_CPU_ENDIAN_BE8 is enabled.

[ Upstream commit fe00e50b2db8c60e4ec90befad1f5bab8ca2c800 ]
We use $(LD) to link vmlinux, modules, decompressors, etc.
VDSO is the only exceptional case where $(CC) is used as the linker
driver, but I do not know why we need to do so. VDSO uses a special
linker script, and does not link standard libraries at all.
I changed the Makefile to use $(LD) rather than $(CC). I confirmed
the same vdso.so.raw was still produced.
Users will be able to use their favorite linker (e.g. lld instead of
of bfd) by passing LD= from the command line.
My plan is to rewrite all VDSO Makefiles to use $(LD), then delete
cc-ldoption.

commit c4ad98e4b72cb5be30ea282fce935248f2300e62 upstream.
KVM currently assumes that an instruction abort can never be a write.
This is in general true, except when the abort is triggered by
a S1PTW on instruction fetch that tries to update the S1 page tables
(to set AF, for example).
This can happen if the page tables have been paged out and brought
back in without seeing a direct write to them (they are thus marked
read only), and the fault handling code will make the PT executable(!)
instead of writable. The guest gets stuck forever.
In these conditions, the permission fault must be considered as
a write so that the Stage-1 update can take place. This is essentially
the I-side equivalent of the problem fixed by 60e21a0ef54c ("arm64: KVM:
Take S1 walks into account when determining S2 write faults").
Update kvm_is_write_fault() to return true on IABT+S1PTW, and introduce
kvm_vcpu_trap_is_exec_fault() that only return true when no faulting
on a S1 fault. Additionally, kvm_vcpu_dabt_iss1tw() is renamed to
kvm_vcpu_abt_iss1tw(), as the above makes it plain that it isn't
specific to data abort.

[ Upstream commit 40ff1ddb5570284e039e0ff14d7a859a73dc3673 ]
The stacktrace code can read beyond the stack size, when it attempts to
read pt_regs from exception frames.
This can happen on normal, non-corrupt stacks. Since the unwind
information in the extable is not correct for function prologues, the
unwinding code can return data from the stack which is not actually the
caller function address, and if in_entry_text() happens to succeed on
this value, we can end up reading data from outside the task's stack
when attempting to read pt_regs, since there is no bounds check.
Example:

The timer fixed interval period pulse generator register
is used to generate periodic pulses. The down count
register loads the value programmed in the fixed period
interval (FIPER). At every tick of the timer accumulator
overflow, the counter decrements by the value of
TMR_CTRL[TCLK_PERIOD]. It generates a pulse when the down
counter value reaches zero. It reloads the down counter
in the cycle following a pulse.
To use the TMR_FIPER register to generate desired periodic
pulses. The value should programmed is,
desired_period - tclk_period
Current tmr-fiper2 value is to generate 100us periodic pulses.
(But the value should have been 99995, not 99990. The tclk_period is 5.)
This patch is to generate 1 second periodic pulses with value
999999995 programmed which is more desired by user.

commit fdfe7cbd58806522e799e2a50a15aee7f2cbb7b6 upstream.
The 'flags' field of 'struct mmu_notifier_range' is used to indicate
whether invalidate_range_{start,end}() are permitted to block. In the
case of kvm_mmu_notifier_invalidate_range_start(), this field is not
forwarded on to the architecture-specific implementation of
kvm_unmap_hva_range() and therefore the backend cannot sensibly decide
whether or not to block.
Add an extra 'flags' parameter to kvm_unmap_hva_range() so that
architectures are aware as to whether or not they are permitted to block.

commit b4d5ec9b39f8b31d98f65bc5577b5d15d93795d7 upstream.
Since clang does not push pc and sp in function prologues, the current
implementation of unwind_frame does not work. By using the previous
frame's lr/fp instead of saved pc/sp we get valid unwinds on clang-built
kernels.
The bounds check on next frame pointer must be changed as well since
there are 8 less bytes between frames.
This fixes /proc/<pid>/stack.

commit eec13b42d41b0f3339dcf0c4da43734427c68620 upstream.
Unprivileged memory accesses generated by the so-called "translated"
instructions (e.g. LDRT) in kernel mode can cause user watchpoints to fire
unexpectedly. In such cases, the hw_breakpoint logic will invoke the user
overflow handler which will typically raise a SIGTRAP back to the current
task. This is futile when returning back to the kernel because (a) the
signal won't have been delivered and (b) userspace can't handle the thing
anyway.
Avoid invoking the user overflow handler for watchpoints triggered by
kernel uaccess routines, and instead single-step over the faulting
instruction as we would if no overflow handler had been installed.

[ Upstream commit 679b2ec8e060ca7a90441aff5e7d384720a41b76 ]
This kernel configuration is basically enabling/disabling sr driver quirks
detection. While these quirks are for fairly rare devices (very old CD
burners, and a glucometer), the additional detection of these models is a
very minimal amount of code.
The logic behind the quirks is always built into the sr driver.
This also removes the config from all the defconfig files that are enabling
this already.

[ Upstream commit 0df12a01f4857495816b05f048c4c31439446e35 ]
We can currently sometimes get "RXS timed out" errors and "EOT timed out"
errors with spi transfers.
These errors can be made easy to reproduce by reading the cpcap iio
values in a loop while keeping the CPUs busy by also reading /dev/urandom.
The "RXS timed out" errors we can fix by adding spi-cpol and spi-cpha
in addition to the spi-cs-high property we already have.
The "EOT timed out" errors we can fix by increasing the spi clock rate
to 9.6 MHz. Looks similar MC13783 PMIC says it works at spi clock rates
up to 20 MHz, so let's assume we can pick any rate up to 20 MHz also
for cpcap.

While testing the recent suspend and resume regressions I noticed that
duovero can still end up losing edge gpio interrupts on runtime
suspend. This causes NFSroot easily stopping working after resume on
duovero.
Let's fix the issue by using gpio level interrupts for smsc as then
the gpio interrupt state is seen by the gpio controller on resume.
