    xen/arm: vgic-v3: Delay the initialization of the domain information
    
    A follow-up patch will require to know the number of vCPUs when
    initializating the vGICv3 domain structure. However this information is
    not available at domain creation. This is only known once
    XEN_DOMCTL_max_vpus is called for that domain.
    
    In order to get the max vCPUs around, delay the domain part of the vGIC
    v3 initialization until the first vCPU of the domain is initialized.

    xen/arm: gic: Ensure ordering between read of INTACK and shared data
    
    When an IPI is generated by a CPU, the pattern looks roughly like:
    
      <write shared data>
      dsb(sy);
      <write to GIC to signal SGI>
    
    On the receiving CPU we rely on the fact that, once we've taken the
    interrupt, then the freshly written shared data must be visible to us.
    Put another way, the CPU isn't going to speculate taking an interrupt.
    
    Unfortunately, this assumption turns out to be broken.
    
    Consider that CPUx wants to send an IPI to CPUy, which will cause CPUy
    to read some shared_data. Before CPUx has done anything, a random
    peripheral raises an IRQ to the GIC and the IRQ line on CPUy is raised.
    CPUy then takes the IRQ and starts executing the entry code, heading
    towards gic_handle_irq. Furthermore, let's assume that a bunch of the
    previous interrupts handled by CPUy were SGIs, so the branch predictor
    kicks in and speculates that irqnr will be <16 and we're likely to
    head into handle_IPI. The prefetcher then grabs a speculative copy of
    shared_data which contains a stale value.
    
    Meanwhile, CPUx gets round to updating shared_data and asking the GIC
    to send an SGI to CPUy. Internally, the GIC decides that the SGI is
    more important than the peripheral interrupt (which hasn't yet been
    ACKed) but doesn't need to do anything to CPUy, because the IRQ line
    is already raised.
    
    CPUy then reads the ACK register on the GIC, sees the SGI value which
    confirms the branch prediction and we end up with a stale shared_data
    value.
    
    This patch fixes the problem by adding an smp_rmb() to the IPI entry
    code in do_SGI.
    
    At the same time document the write barrier.

    xen/arm: gic: Ensure we have an ISB between ack and do_IRQ()
    
    Devices that expose their interrupt status registers via system
    registers (e.g. Statistical profiling, CPU PMU, DynamIQ PMU, arch timer,
    vgic (although unused by Linux), ...) rely on a context synchronising
    operation on the CPU to ensure that the updated status register is
    visible to the CPU when handling the interrupt. This usually happens as
    a result of taking the IRQ exception in the first place, but there are
    two race scenarios where this isn't the case.
    
    For example, let's say we have two peripherals (X and Y), where Y uses a
    system register for its interrupt status.
    
    Case 1:
    1. CPU takes an IRQ exception as a result of X raising an interrupt
    2. Y then raises its interrupt line, but the update to its system
       register is not yet visible to the CPU
    3. The GIC decides to expose Y's interrupt number first in the Ack
       register
    4. The CPU runs the IRQ handler for Y, but the status register is stale
    
    Case 2:
    1. CPU takes an IRQ exception as a result of X raising an interrupt
    2. CPU reads the interrupt number for X from the Ack register and runs
       its IRQ handler
    3. Y raises its interrupt line and the Ack register is updated, but
       again, the update to its system register is not yet visible to the
       CPU.
    4. Since the GIC drivers poll the Ack register, we read Y's interrupt
       number and run its handler without a context synchronisation
       operation, therefore seeing the stale register value.
    
    In either case, we run the risk of missing an IRQ. This patch solves the
    problem by ensuring that we execute an ISB in the GIC drivers prior
    to invoking the interrupt handler.
    
    Based on Linux commit 39a06b67c2c1256bcf2361a1f67d2529f70ab206

    xen/arm: smccc-1.1: Handle function result as parameters
    
    If someone has the silly idea to write something along those lines:
    
            extern u64 foo(void);
    
            void bar(struct arm_smccc_res *res)
            {
                    arm_smccc_1_1_smc(0xbad, foo(), res);
            }
    
    they are in for a surprise, as this gets compiled as:
    
            0000000000000588 <bar>:
             588:   a9be7bfd        stp     x29, x30, [sp, #-32]!
             58c:   910003fd        mov     x29, sp
             590:   f9000bf3        str     x19, [sp, #16]
             594:   aa0003f3        mov     x19, x0
             598:   aa1e03e0        mov     x0, x30

             5a0:   94000000        bl      0 <foo>
             5a4:   aa0003e1        mov     x1, x0
             5a8:   d4000003        smc     #0x0
             5ac:   b4000073        cbz     x19, 5b8 <bar+0x30>
             5b0:   a9000660        stp     x0, x1, [x19]
             5b4:   a9010e62        stp     x2, x3, [x19, #16]
             5b8:   f9400bf3        ldr     x19, [sp, #16]
             5bc:   a8c27bfd        ldp     x29, x30, [sp], #32
             5c0:   d65f03c0        ret
             5c4:   d503201f        nop
    
    The call to foo "overwrites" the x0 register for the return value,
    and we end up calling the wrong secure service.
    
    A solution is to evaluate all the parameters before assigning
    anything to specific registers, leading to the expected result:
    
            0000000000000588 <bar>:
             588:   a9be7bfd        stp     x29, x30, [sp, #-32]!

             594:   aa0003f3        mov     x19, x0
             598:   aa1e03e0        mov     x0, x30

    xen/arm: smccc-1.1: Make return values unsigned long
    
    An unfortunate consequence of having a strong typing for the input
    values to the SMC call is that it also affects the type of the
    return values, limiting r0 to 32 bits and r{1,2,3} to whatever
    was passed as an input.
    
    Let's turn everything into "unsigned long", which satisfies the
    requirements of both architectures, and allows for the full
    range of return values.
