2022-05-04irqchip/gic-v3: Relax polling of GIC{R,D}_CTLR.RWPMarc Zyngier
Recent work on the KVM GIC emulation has revealed that the GICv3 driver is a bit RWP-happy, as it polls this bit for each and every write MMIO access involving a single interrupt. As it turns out, polling RWP is only required when: - Disabling an SGI, PPI or SPI - Disabling LPIs at the redistributor level - Disabling groups - Enabling ARE - Dealing with DPG* Simplify the driver by removing all the other instances of RWP polling, and add the one that was missing when enabling the distributor (as that's where we set ARE).

2022-05-04irqchip/gic-v3: Detect LPI invalidation MMIO registersMarc Zyngier
Since GICv4.1, an implementation can offer the same MMIO-based implementation as DirectLPI, only with an ITS. Given that this can be hugely beneficial for workloads that are very LPI masking heavy (although these workloads are admitedly a bit odd). Interestingly, this is independent of RVPEI, which only *implies* the functionnality. So let's detect whether the implementation has GICR_CTLR.IR set, and propagate this as DirectLPI to the ITS driver. While we're at it, repaint the GICv3 banner so that we advertise the various capabilities at boot time to be slightly less invasive.

2022-05-04RDMA/rxe: Replace paylen by payloadBob Pearson
In finish_packet() in rxe_req.c a variable was incorrectly called paylen instead of payload. Elsewhere in the rxe source payload is always used for the RoCE payload length and paylen is always used for the UDP payload length. This will cause unnecessary confusion. Replace paylen by payload in finish_packet().

With the new mechanism, the pptable transferring has to be via PSP. That requires the pptable ucode(and necessary bootupp values retrieving) must be ready before ->hw_init phase of PSP.
