| |
3.0-stable review patch. If anyone has any objections, please let me know.
------------------
From: Benjamin Herrenschmidt <benh@kernel.crashing.org>
commit c055fe0797b7bd8f6f21a13598a55a16d5c13ae7 upstream.
We used to try to request 8 times more vram than needed, which would fail if the card has a too small BAR (observed with qemu & kvm).
