However, drivers like bcm5974, which claims support for reporting 16 fingers simultaneously, can have an extraordinarily large buffer. The resultant contiguous order-4 allocation attempt fails due to fragmentation, and the device is thus unusable until reboot. Try kzalloc if we can to avoid the mapping overhead, but if that fails, fall back to vzalloc.
