Module Name:    src
Committed By:   bouyer
Date:           Tue May 24 14:00:24 UTC 2022

Modified Files:
        src/sys/arch/x86/pci: msipic.c pci_machdep.c
        src/sys/arch/xen/x86: pintr.c xen_intr.c

Log Message:
- msipic_construct_msix_pic(): set mp_table_base to memaddr (without
  table_offset), this is what Xen wants
while there use pci_conf_write16() in msi_set_msictl_enablebit() too,
for consistency (it seems that Xen accepts the 32bit write at this point,
but this may change).

- xen_map_msix_pirq(): don't forget to set map_irq.table_base in the
  MSI-X case, otherwise Xen maps it as MSI
- call pic_hwunmask() after pirq_establish() in msi/msix case, to make sure
  the msi-x vector is unmasked.

Now MSI-X works with Xen so stop disabling it in pci_attach_hook().
