["Nick Hudson" <skrll%netbsd.org@localhost>]

Module Name:    src
Committed By:   skrll
Date:           Wed Dec 22 21:45:02 UTC 2021

Modified Files:
        src/sys/dev/acpi: ehci_acpi.c
        src/sys/dev/pci: ehci_pci.c
        src/sys/dev/usb: ehci.c ehcivar.h

Log Message:
Three fixes

- pass the 64bit DMA tag if the HCCPARAMS says ehci supports it and the
  64bit DMA tag is available/valid.  This should help with the
  "cannot create xfer" error on 64bit systems.

- restrict the control structure memory allocation to the low 4GB
  (CTRLDSSEGMENT was always set to zero anyway)

- if ehci_init fails then tidyup before returning the error.
