The quilt patch titled Subject: printk: stop including cache.h from printk.h has been removed from the -mm tree. Its filename was printk-stop-including-cacheh-from-printkh.patch This patch was dropped because it was merged into mm-stable ------------------------------------------------------ From: Peter Collingbourne <pcc@xxxxxxxxxx> Subject: printk: stop including cache.h from printk.h An inclusion of cache.h in printk.h was added in 2014 in commit c28aa1f0a847 ("printk/cache: mark printk_once test variable __read_mostly") in order to bring in the definition of __read_mostly. The usage of __read_mostly was later removed in commit 3ec25826ae33 ("printk: Tie printk_once / printk_deferred_once into .data.once for reset") which made the inclusion of cache.h unnecessary, so remove it. We have a small amount of code that depended on the inclusion of cache.h from printk.h; fix that code to include the appropriate header. This fixes a circular inclusion on arm64 (linux/printk.h -> linux/cache.h -> asm/cache.h -> linux/kasan-enabled.h -> linux/static_key.h -> linux/jump_label.h -> linux/bug.h -> asm/bug.h -> linux/printk.h) that would otherwise be introduced by the next patch. Build tested using {allyesconfig,defconfig} x {arm64,x86_64}.
