This patch modifies virtio-console to use virtio_config_val() instead of a 'if(virtio_has_feature()) vdev->config->get()' construct to retrieve optional values from the config space.

Aiming these for coming merge window. Nothing should change, but get ready for a non-guest-endian config transports, and > 32 features bits. Final one is just an overdue consolidation. Cheers, Rusty. Rusty Russell (7): virtio_config: introduce size-based accessors. virtio: use size-based config accessors. virtio_config: helpers for non-converting accessors. virtio_config: make

Add low level APIs to test/set/clear feature bits. For use by transports, to make it easier to write code independent of feature bit array format. Note: APIs is prefixed with __ and has _bit suffix to stress its low level nature. It's for use by transports only: drivers should use virtio_has_feature and never need to set/clear features.

Change u32 to u64, and use BIT_ULL and 1ULL everywhere. Note: transports are unchanged, and only set low 32 bit. This guarantees that no transport sets e.g. VERSION_1 by mistake without proper support. Based on patch by Rusty.
