Subject: i965: Set the max index buffer address correctly according to the docs.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=213ac4bb5de1cef601e0677ef2e5ca1779851e28;p=mesa.git

i965: Set the max index buffer address correctly according to the docs.

It's the last addressable byte, not the byte after the end of the buffer.
(cherry picked from commit b72dea5441e8e9226dabf1826fa3bc129c7bc281)
