Subject: gallium/radeon: Don't assign virtual address space for BO that already has one.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=18abc270c56d5debc02a196634583a25074b3fef;p=mesa.git

gallium/radeon: Don't assign virtual address space for BO that already has one.

We'd end up re-using the old one and throwing away the new one anyway, but only
after a roundtrip to the kernel.
