2021-06-01KVM: arm64: vgic: Implement SW-driven deactivationMarc Zyngier1-0/+10
In order to deal with these systems that do not offer HW-based deactivation of interrupts, let implement a SW-based approach: - When the irq is queued into a LR, treat it as a pure virtual interrupt and set the EOI flag in the LR. - When the interrupt state is read back from the LR, force a deactivation when the state is invalid (neither active nor pending) Interrupts requiring such treatment get the VGIC_SW_RESAMPLE flag.

2021-06-01KVM: arm64: vgic: move irq->get_input_level into an ops structureMarc Zyngier1-11/+17
We already have the option to attach a callback to an interrupt to retrieve its pending state. As we are planning to expand this facility, move this callback into its own data structure. This will limit the size of individual interrupts as the ops structures can be shared across multiple interrupts. Signed-off-by: Marc Zyngier <maz@kernel.org>
2021-06-01KVM: arm64: vgic: Let an interrupt controller advertise lack of HW deactivationMarc Zyngier2-0/+5
The vGIC, as architected by ARM, allows a virtual interrupt to trigger the deactivation of a physical interrupt. This allows the following interrupt to be delivered without requiring an exit. However, some implementations have choosen not to implement this, meaning that we will need some unsavoury workarounds to deal with this. On detecting such a case, taint the kernel and spit a nastygram. We'll deal with this in later patches. Signed-off-by: Marc Zyngier <maz@kernel.org>
2021-06-01KVM: arm64: vgic: Be tolerant to the lack of maintenance interrupt maskingMarc Zyngier1-0/+2
As it turns out, not all the interrupt controllers are able to expose a vGIC maintenance interrupt that can be independently enabled/disabled. And to be fair, it doesn't really matter as all we require is for the interrupt to kick us out of guest mode out way or another. To that effect, add gic_kvm_info.no_maint_irq_mask for an interrupt controller to advertise the lack of masking. Signed-off-by: Marc Zyngier <maz@kernel.org>
2021-06-01irqchip/gic: Split vGIC probing information from the GIC codeMarc Zyngier2-24/+42
The vGIC advertising code is unsurprisingly very much tied to the GIC implementations. However, we are about to extend the support to lesser implementations. Let's dissociate the vgic registration from the GIC code and move it into KVM, where it makes a bit more sense. This also allows us to mark the gic_kvm_info structures as __initdata.

2021-06-01scsi: core: Drop obsolete Linux-specific SCSI status codesHannes Reinecke3-22/+21
Originally the SCSI subsystem has been using 'special' SCSI status codes, which were the SAM-specified ones but shifted by 1. As most drivers have now been modified to use the SAM-specified ones, having two nearly identical sets of definitions only causes confusion. The Linux-specifed SCSI status codes have been marked obsolete for several years so drop them and use the SAM-specified status codes throughout.

2021-05-31mac80211: Fix NULL ptr deref for injected rate infoMathy Vanhoef1-1/+6
The commit cb17ed29a7a5 ("mac80211: parse radiotap header when selecting Tx queue") moved the code to validate the radiotap header from ieee80211_monitor_start_xmit to ieee80211_parse_tx_radiotap. This made is possible to share more code with the new Tx queue selection code for injected frames. But at the same time, it now required the call of ieee80211_parse_tx_radiotap at the beginning of functions which wanted to handle the radiotap header. And this broke the rate parser for radiotap header parser. The radiotap parser for rates is operating most of the time only on the data in the actual radiotap header. But for the 802.11a/b/g rates, it must also know the selected band from the chandef information. But this information is only written to the ieee80211_tx_info at the end of the ieee80211_monitor_start_xmit - long after ieee80211_parse_tx_radiotap was already called. The info->band information was therefore always 0 (NL80211_BAND_2GHZ) when the parser code tried to access it. For a 5GHz only device, injecting a frame with 802.11a rates would cause a NULL pointer dereference because local->hw.wiphy->bands[NL80211_BAND_2GHZ] would most likely have been NULL when the radiotap parser searched for the correct rate index of the driver.

2021-05-28i2c: core: support bus regulator controlling in adapterBibby Hsieh1-0/+2

We can control bulk regulator if it is provided in i2c adapter device.
