Christoph Hellwig correctly pointed out [1] that the AF_XDP core was pointlessly including internal headers. Let us remove those includes.

Currently, there are two test cases with same name "ALU64_SMOD_X: -7 % 2 = -1", the first one is right, the second one should be ALU64_SMOD_K because its code is BPF_ALU64 | BPF_MOD | BPF_K.

But that needs * the BLK-CTL module BUS clk-en bit being set. * * There is a separate BLK-CTL module and we will have such a driver for it, * that driver will set the BUS clk-en bit and handshake will be triggered * automatically there. Just add a delay and suppose the handshake finish * after that. */ } The BLK-CTL module needs to add delay to wait for a handshake request finished. For some BLK-CTL module (eg. AudioMix on i.MX8MP) doesn't have BUS clk-en bit, it is better to add delay in this driver, as the BLK-CTL module doesn't need to care about how it is powered up. regmap_read_bypassed() is to make sure the above write IO transaction already reaches target before udelay().
