xdp_umem.c had overlapping changes between the 64-bit math fix for the calculation of npgs and the removal of the zerocopy memory type which got rid of the chunk_size_nohdr member. The mlx5 Kconfig conflict is a case where we just take the net-next copy of the Kconfig entry dependency as it takes on the ESWITCH dependency by one level of indirection which is what the 'net' conflicting change is trying to ensure.

2020-05-31KVM: arm64: Flush the instruction cache if not unmapping the VM on rebootMarc Zyngier1-4/+10
On a system with FWB, we don't need to unmap Stage-2 on reboot, as even if userspace takes this opportunity to repaint the whole of memory, FWB ensures that the data side stays consistent even if the guest uses non-cacheable mappings. However, the I-side is not necessarily coherent with the D-side if CTR_EL0.DIC is 0. In this case, invalidate the i-cache to preserve coherency.

2020-05-28KVM: arm64: Move __load_guest_stage2 to kvm_mmu.hMarc Zyngier2-18/+17
Having __load_guest_stage2 in kvm_hyp.h is quickly going to trigger a circular include problem. In order to avoid this, let's move it to kvm_mmu.h, where it will be a better fit anyway. In the process, drop the __hyp_text annotation, which doesn't help as the function is marked as __always_inline.

2020-05-28KVM: arm64: Parametrize exception entry with a target ELMarc Zyngier2-37/+39
We currently assume that an exception is delivered to EL1, always. Once we emulate EL2, this no longer will be the case. To prepare for this, add a target_mode parameter. While we're at it, merge the computing of the target PC and PSTATE in a single function that updates both PC and CPSR after saving their previous values in the corresponding ELR/SPSR. This ensures that they are updated in the correct order (a pretty common source of bugs...). Reviewed-by: Mark Rutland <mark.rutland@arm.com> Signed-off-by: Marc Zyngier <maz@kernel.org>
2020-05-28arm64/kernel: Fix return value when cpu_online() fails in __cpu_up()Nobuhiro Iwamatsu1-1/+1
If boot_secondary() was successful, and cpu_online() was an error in __cpu_up(), -EIO was returned, but 0 is returned by commit d22b115cbfbb7 ("arm64/kernel: Simplify __cpu_up() by bailing out early"). Therefore, bringup_wait_for_ap() causes the primary core to wait for a long time, which may cause boot failure. This commit sets -EIO to return code under the same conditions.

2020-05-28KVM: arm64: Don't use empty structures as CPU reset stateMarc Zyngier1-12/+9

2020-05-28KVM: arm64: Move sysreg reset check to boot timeMarc Zyngier1-37/+35
Our sysreg reset check has become a bit silly, as it only checks whether a reset callback actually exists for a given sysreg entry, and apply the method if available. Doing the check at each vcpu reset is pretty dumb, as the tables never change. It is thus perfectly possible to do the same checks at boot time. This also allows us to introduce a sparse sys_regs[] array, something that will be required with ARMv8.4-NV. Signed-off-by: Marc Zyngier <maz@kernel.org>

Note that these only cover *CLR registers that were always covered by their *SET counterpart, so there is no semantic change here.

If we move the used_lrs field to the version-specific cpu interface structure, the following functions only operate on the struct vgic_v3_cpu_if and not the full vcpu: __vgic_v3_save_state __vgic_v3_restore_state __vgic_v3_activate_traps __vgic_v3_deactivate_traps __vgic_v3_save_aprs __vgic_v3_restore_aprs This is going to be very useful for nested virt, so move the used_lrs field and change the prototypes and implementations of these functions to take the cpu_if parameter directly.

2020-05-27arm64/cpufeature: Add get_arm64_ftr_reg_nowarn()Anshuman Khandual1-10/+34
There is no way to proceed when requested register could not be searched in arm64_ftr_reg[]. Requesting for a non present register would be an error as well. Hence lets just WARN_ON() when search fails in get_arm64_ftr_reg() rather than checking for return value and doing a BUG_ON() instead in some individual callers. But there are also caller instances that dont error out when register search fails. Add a new helper get_arm64_ftr_reg_nowarn() for such cases.

2020-05-25watchdog: Add new arm_smc_wdt watchdog driverJulius Werner1-0/+1
This patch adds a watchdog driver that can be used on ARM systems with the appropriate watchdog implemented in Secure Monitor firmware. The driver communicates with firmware via a Secure Monitor Call. This may be useful for platforms using TrustZone that want the Secure Monitor firmware to have the final control over the watchdog. This is implemented on mt8173 chromebook devices oak, elm and hana in arm trusted firmware file plat/mediatek/mt8173/drivers/wdt/wdt.c.
