This patch series removes the messy dependencies from SERIO_I8042 by having it depend on one variable (ARCH_MAY_HAVE_PC_SERIO) and having architectures which need it select that variable in arch/*/Kconfig.
New architectures are unlikely to need SERIO_I8042, so this avoids having an ever growing list of architectures to exclude. If an architecture without i8042 support isn't excluded through the dependency list for SERIO_I8042 or through explicit disabling in a config, it will likely panic on boot with something similar to this (from arm64): [ 27.426181] [<ffffffc000403b1c>] i8042_flush+0x88/0x10c [ 27.426251] [<ffffffc00084cc2c>] i8042_init+0x58/0xe8 [ 27.426320] [<ffffffc000080bec>] do_one_initcall+0xc4/0x14c [ 27.426404] [<ffffffc000820970>] kernel_init_freeable+0x1a4/0x244 [ 27.426480] [<ffffffc0005a894c>] kernel_init+0x18/0x148 [ 27.426561] Code: d2800c82 f2bf7c02 f2dff7e2 f2ffffe2 (39400042) [ 27.426789] ---[ end trace ac076843cf0f383e ]--- [ 27.426875] Kernel panic - not syncing: Attempted to kill init! exitcode=0x0000000b This is v2 of the patch series. Changes from version 1: o Added acks. arm, ia64, and sh are only ones without acks. o Moved select of ARCH_MIGHT_HAVE_PC_SERIO to board-specific Kconfigs for arm and sh.
