Hi, Multiple architectures are affected in the first patch and all further patches depend on the first. Maybe this could go in through Andrew Morton's tree? Changes since v2 ================ 1. Drop all non-essential patches (cleanups), 2. Update also drivers/sh/clk/cpg.c . Changes since v1 ================ https://lore.kernel.org/lkml/1578415992-24054-1-git-send-email-krzk at

Hi, Changes since v1 ================ https://lore.kernel.org/lkml/1578415992-24054-1-git-send-email-krzk at kernel.org/ 1. Constify also ioreadX_rep() and mmio_insX(), 2. Squash lib+alpha+powerpc+parisc+sh into one patch for bisectability, 3. Add acks and reviews, 4. Re-order patches so all optional driver changes are at the end. Description =========== The ioread8/16/32() and others have
