From: Andy Shevchenko <andriy.shevchenko@xxxxxxxxxxxxxxx> Subject: kernel.h: drop unneeded <linux/kernel.h> inclusion from other headers Patch series "kernel.h further split", v5. kernel.h is a set of something which is not related to each other and often used in non-crossed compilation units, especially when drivers need only one or two macro definitions from it. This patch (of 7): There is no evidence we need kernel.h inclusion in certain headers. Drop unneeded <linux/kernel.h> inclusion from other headers.
