During a TLB invalidate sequence targeting the inner shareable domain,
Falkor may prematurely complete the DSB before all loads and stores using
the old translation are observed. Instruction fetches are not subject to
the conditions of this erratum. If the original code sequence includes
multiple TLB invalidate instructions followed by a single DSB, onle one of
the TLB instructions needs to be repeated to work around this erratum.
While the erratum only applies to cases in which the TLBI specifies the
inner-shareable domain (*IS form of TLBI) and the DSB is ISH form or
stronger (OSH, SYS), this changes applies the workaround overabundantly--
to local TLBI, DSB NSH sequences as well--for simplicity.

cputime_t is now only used by two architectures:
* powerpc (when CONFIG_VIRT_CPU_ACCOUNTING_NATIVE=y)
* s390
And since the core doesn't use it anymore, we don't need any arch support
from the others. So we can remove their stub implementations.
A final cleanup would be to provide an efficient pure arch
implementation of cputime_to_nsec() for s390 and powerpc and finally
remove include/linux/cputime.h .

Add initial clock configuration for display subsystem for Exynos5433
based TM2/TM2e boards in device tree in order to avoid dependency on the
configuration left by the bootloader. This initial configuration is also
needed to ensure that display subsystem is operational if display power
domain gets turned off before clock controller is probed and the inital
clock configuration left by the bootloader saved.
TM2 and TM2e uses different rate for DISP PLL clock, but for better
maintainability all 'assigned-clocks-*' properties for DISP CMU are
defines in each board dts instead of redefining the rates property.

Commit cab15ce604e5 ("arm64: Introduce execute-only page access
permissions") allowed a valid user PTE to have the PTE_USER bit clear.
As a consequence, the pte_valid_not_user() macro in set_pte() was
replaced with pte_valid_global() under the assumption that only user
pages have the nG bit set. EFI mappings, however, also have the nG bit
set and set_pte() wrongly ignores issuing the DSB+ISB.
This patch reinstates the pte_valid_not_user() macro and adds the
PTE_UXN bit check since all kernel mappings have this bit set. For
clarity, pte_exec() is renamed to pte_user_exec() as it only checks for
the absence of PTE_UXN. Consequently, the user executable check in
set_pte_at() drops the pte_ng() test since pte_user_exec() is
sufficient.

Some boards use resistor ladder buttons connected through one of the ADC

Now that we unconditionally flush newly mapped pages to the PoC,

When we fault in a page, we flush it to the PoC (Point of Coherency)
if the faulting vcpu has its own caches off, so that it can observe
the page we just brought it.
But if the vcpu has its caches on, we skip that step. Bad things
happen when *another* vcpu tries to access that page with its own
caches disabled. At that point, there is no garantee that the
data has made it to the PoC, and we access stale data.
The obvious fix is to always flush to PoC when a page is faulted
in, no matter what the state of the vcpu is.

VGICv3 CPU interface registers are accessed using
KVM_DEV_ARM_VGIC_CPU_SYSREGS ioctl. These registers are accessed
as 64-bit. The cpu MPIDR value is passed along with register id.
It is used to identify the cpu for registers access.
The VM that supports SEIs expect it on destination machine to handle
guest aborts and hence checked for ICC_CTLR_EL1.SEIS compatibility.
Similarly, VM that supports Affinity Level 3 that is required for AArch64
mode, is required to be supported on destination machine. Hence checked
for ICC_CTLR_EL1.A3V compatibility.
The arch/arm64/kvm/vgic-sys-reg-v3.c handles read and write of VGIC
CPU registers for AArch64.
For AArch32 mode, arch/arm/kvm/vgic-v3-coproc.c file is created but
APIs are not implemented.
Updated arch/arm/include/uapi/asm/kvm.h with new definitions
required to compile for AArch32.

The Banana Pi M64 board is a typical single board computer based on the
Allwinner A64 SoC. Aside from the usual peripherals it features eMMC
storage, which is connected to the 8-bit capable SDHC2 controller.
Also it has a soldered WiFi/Bluetooth chip, so we enable UART1 and SDHC1

The eMMC controller seem to have a maximum frequency of 200MHz, while the
regular MMC controllers are capped at 150MHz.
Since older SoCs cannot go that high, we cannot change the default maximum
frequency, but fortunately for us we have a property for that in the DT.
This also has the side effect of allowing to use the MMC HS200 and SD
SDR104 modes for the boards that support it (with either 1.2v or 1.8v IOs).

The A64 has 3 MMC controllers, one of them being especially targeted to
eMMC. Among other things, it has a data strobe signal and a 8 bits data
width.
The two other are more usual controllers that will have a 4 bits width at
most and no data strobe signal, which limits it to more usual SD or MMC

If an EL0 instruction in the SYS class triggers an exception, do_sysintr
looks for a sys64_hook matching the instruction, and if none is found,
injects a SIGILL. This mirrors what we do for undefined instruction
encodings in do_undefinstr, where we look for an undef_hook matching the
instruction, and if none is found, inject a SIGILL.
Over time, new SYS instruction encodings may be allocated. Prior to
allocation, exceptions resulting from these would be handled by
do_undefinstr, whereas after allocation these may be handled by
do_sysintr.
To ensure that we have consistent behaviour if and when this happens, it
would be beneficial to have do_sysinstr fall back to do_undefinstr.

OdroidC2 GbE link breaks under heavy tx transfer. This happens even if the
MAC does not enable Energy Efficient Ethernet (No Low Power state Idle on
the Tx path). The problem seems to come from the phy Rx path, entering the
LPI state.
Disabling EEE advertisement on the phy prevent this feature to be
negociated with the link partner and solve the issue.

Refactor the KVM code to use the __tlbi macros, which will allow an errata
workaround that repeats tlbi dsb sequences to only change one location.
This is not intended to change the generated assembly and comparing before
and after vmlinux objdump shows no functional changes.

On ACPI based systems where the topology is setup using the API
store_cpu_topology, at the moment we do not have necessary code
to parse cpu capacity and handle cpufreq notifier, thus

Testing with an Armada 8040 board shows that adding the generic-ahci
compatible to the CP110 AHCI nodes gets us working AHCI on the board.
A previous patch series posted by Thomas Petazzoni was retracted when
it was realised that the IP was supposed to be, and is, compatible
with the standard register layout.
Add this compatible.

Current r8a7795.dtsi defines audma -> ipmmu -> dma order.
Because of this order, dma can connect to ipmmu, but
audma can't connect to it.
This patch moves audma order as ipmmu -> dma -> audma.

Link the ARM GIC to the INTC-AP module clock, and add it to the SYSC
"always-on" PM Domain, so it can be power managed using that clock.
Note that currently the GIC-400 driver doesn't support module clocks nor
Runtime PM, so this must be handled as a critical clock.
