gpiolib/arches: Centralise bolierplate asm/gpio.h Rather than requiring architectures that use gpiolib but don't have any need to define anything custom to copy an asm/gpio.h provide a Kconfig symbol which architectures must select in order to include gpio.h and for other architectures just provide the trivial implementation directly. This makes it much easier to do gpiolib updates and is also a step towards making gpiolib APIs available on every architecture. For architectures with existing boilerplate code leave a stub header in place which warns on direct inclusion of asm/gpio.h and includes linux/gpio.h to catch code that's doing this. Direct inclusion of asm/gpio.h has long been deprecated.

lib: move GENERIC_IOMAP to lib/Kconfig define GENERIC_IOMAP in a central location instead of all architectures. This will be helpful for the follow-up patch which makes it select other configs. Code is also a bit shorter this way. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>

Make most arch asm/module.h files use asm-generic/module.h Use the mapping of Elf_[SPE]hdr, Elf_Addr, Elf_Sym, Elf_Dyn, Elf_Rel/Rela, ELF_R_TYPE() and ELF_R_SYM() to either the 32-bit version or the 64-bit version into asm-generic/module.h for all arches bar MIPS. Also, use the generic definition mod_arch_specific where possible. To this end, I've defined three new config bools: (*) HAVE_MOD_ARCH_SPECIFIC Arches define this if they don't want to use the empty generic mod_arch_specific struct. (*) MODULES_USE_ELF_RELA Arches define this if their modules can contain RELA records. This causes the Elf_Rela mapping to be emitted and allows apply_relocate_add() to be defined by the arch rather than have the core emit an error message. (*) MODULES_USE_ELF_REL Arches define this if their modules can contain REL records. This causes the Elf_Rel mapping to be emitted and allows apply_relocate() to be defined by the arch rather than have the core emit an error message. Note that it is possible to allow both REL and RELA records: m68k and mips are two arches that do this. With this, some arch asm/module.h files can be deleted entirely and replaced with a generic-y marker in the arch Kbuild file. Additionally, I have removed the bits from m32r and score that handle the unsupported type of relocation record as that's now handled centrally.

UniCore32 bugfix: add missed CONFIG_ZONE_DMA Because our PCI-bus handler confines dma zone into 128M, we should add CONFIG_ZONE_DMA for all boards. Otherwise, all memory bigger than 128M will be pushed into ZONE_MOVABLE.

Find out whether you have a PCI motherboard. PCI is the name of a
bus system, i.e. the way the CPU talks to the other stuff inside
your box. Other bus systems are ISA, EISA, MicroChannel (MCA) or
VESA. If you have PCI, say Y, otherwise N.

help
Unicore processors can not fetch/store information which is not
naturally aligned on the bus, i.e., a 4 byte fetch must start at an
address divisible by 4. On 32-bit Unicore processors, these non-aligned
fetch/store instructions will be emulated in software if you say
here, which has a severe performance impact. This is necessary for
correct operation of some network protocols. With an IP-only
configuration it is safe to say N, otherwise say Y.

Always use the default kernel command string, even if the boot
loader passes other arguments to the kernel.
This is useful if you cannot or don't want to change the
command-line options your boot loader passes to the kernel.
If unsure, say N.
