Subject: [PATCH 1/1] RDMA: Disable IB HW for UML
Git-commit: 323a74fc20f53c0d0e13a16aee703a30d9751235
Patch-mainline: v6.2-rc1
References: git-fixes

Disable all of drivers/infiniband/hw/ and rdmavt for UML builds until
someone needs it and provides patches to support it.

This prevents build errors in hw/qib/qib_wc_x86_64.c.

Fixes: 68f5d3f3b654 ("um: add PCI over virtio emulation driver")
