If the bios or OS sets the pci max read request size to 0 or an invalid value (6,7), it can result in a hang or slowdown. Check and set it to something sane if it's invalid. Fixes: https://bugzilla.kernel.org/show_bug.cgi?id=42162 v2: use pci reg defines from include/linux/pci_regs.h Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Cc: stable@kernel.org Reviewed-by: Michel Dänzer <michel.daenzer@amd.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
