This helper is also useful for other iommu devices (virtio-iommu, SMMUv3) to make sure IOMMU UNMAP notifiers only are called with power of 2 range sizes. Let's move this latter into dma-helpers.c and rename it into dma_aligned_pow2_mask(). Also rewrite the helper so that it accomodates UINT64_MAX values for the size mask and max mask. It now returns a mask instead of a size. Change the caller.

It searches for a list of consecutive descriptors whichs are flagged as ready for processing and transmits their payloads accordingly. The controller stops processing once it finds a descriptor that is not marked ready. While the above behaviour works in most situations, it is not the same as the actual EMAC in hardware. Actual hardware uses the TX_CUR_DESC register value to keep track of the last position in the transmit queue and continues processing from that position when software triggers the start of DMA processing. The currently emulated behaviour can lead to packet loss on transmit when software fills the transmit queue with ready descriptors that overlap the tail of the circular list. This commit modifies the emulated EMAC for sun8i such that it processes the transmit queue using the TX_CUR_DESC register in the same way as hardware.

If that bound is lower than the highest possible GPA for the machine, then QEMU will error out. However, the IPA is set to 40 when the highest GPA is less than or equal to 40, even when KVM may support an IPA limit as low as 32. This means KVM may fail the VM creation unnecessarily. Additionally, 40 is selected with the value 0, which means use the default, and that gets around a check in some versions of KVM, causing a difficult to debug fail. Always use the IPA size that corresponds to the highest possible GPA, unless it's lower than 32, in which case use 32. Also, we must still use 0 when KVM only supports the legacy fixed 40 bit IPA.

This module is mainly used to configure PWM fans. It has just enough functionality to make the PWM fan kernel module work. The module takes two input, the max_rpm of a fan (modifiable via QMP) and duty cycle (a GPIO from the PWM module.) The actual measured RPM is equal to max_rpm * duty_cycle / NPCM7XX_PWM_MAX_DUTY. The RPM is measured as a counter compared to a prescaled input clock. The kernel driver reads this counter and report to user space.

This works for the case where we do want to create a TLB entry, because we know the common TLB code only creates entries of the TARGET_PAGE_SIZE and asking for a size larger than that only means that invalidations invalidate the whole larger area. However, if lg_page_size is smaller than TARGET_PAGE_SIZE this effectively means "don't create a TLB entry"; in this case if either S1 or S2 said "this covers less than a page and can't go in a TLB" then the final result also should be marked that way. Set the resulting page size to 0 if either stage asked for a less-than-a-page entry, and expand the comment to explain what's going on. This has no effect for VMSA because currently the VMSA lookup always returns results that cover at least TARGET_PAGE_SIZE; however when we add v8R support it will reuse this code path, and for v8R the S1 and S2 results can be smaller than TARGET_PAGE_SIZE.

Rather than converting the MAIR format to the format used for VMSA stage 2 (bits [5:2] of a VMSA stage 2 descriptor) and then converting back to do the attribute combination, allow combined_attrs_nofwb() to accept s2 attributes that are already in the MAIR format. We move the assert() to combined_attrs_fwb(), because that function really does require a VMSA stage 2 attribute format. (We will never get there for v8R, because PMSAv8 does not implement FEAT_S2FWB.)
