This is mainly set of cleanups of asm-generic/io.h, resolving problems with inconsistent semantics of ioread64/iowrite64 that were causing runtime and build issues. The "GENERIC_IOMAP" version that switches between inb()/outb() and readb()/writeb() style accessors is now only used on architectures that have PC-style ISA devices that are not memory mapped (x86, uml, m68k-q40 and powerpc-powernv), while alpha and parisc use a more complicated variant and everything else just maps the ioread interfaces to plan MMIO (readb/writeb etc). In addition there are two small changes from Raag Jadav to simplify the asm-generic/io.h indirect inclusions and from Jann Horn to fix a corner case with read_word_at_a_time. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEiK/NIGsWEZVxh/FrYKtH/8kJUicFAmfkb2MACgkQYKtH/8kJ UicZMg//Va7h0cZBAM64yvHH9SJ1JrM2u4oZNspvcWuncpqaDp3/lFAUBf1m0m46 PhZ8mJmVm/qD7DH8uJRA4kI9t0hjeI1nwb2Pgo60omEpZKY2nIJMsJMIluQYEdAt nthz9RUvNOu0WSR/zMVmLfEAtncNewJzyUrlTnoQnIM9S+WQ8e5f1TxZbaz754Cb XYOpfZNj4nyP3wXtMedee3eZiKKxs/OcZBLoGyKnrBIkUbHCucXsAL962SoI3AXr pMjAIVNC1588fhOc2fA9Jl3K73j8Tj7/34UM+ztd5wxI1lwepxq4EDOCyJrhF5Oh z7oZ4laGoIc4i1aSrUWFK10TrcSBvC9D3zvUjYL8ryYw3HrpB3VppcObpCBtpWZS 97LGSlwq8UmkQOXt8xFzffOEDSh97ojxJAvUUUtuQtnS7PbkmyZ/OCnddBb0F7pa Bg68mzzZHm8/WUCMXwKxh+GA+qVZsMsPaPaexS/aG/TuV7+Mnj93GY1GSkj3Qzaw T9eUuGnFRCvSHU/WJ/Lrl4X1dFdWgHAbSOMNZBVfRFgSUt1ypChV1Sqt2jEfe6Uv dEeD84vZ0uhTsLoFVv/V4xY0osGKL+kAAtEwszLPfmP43kH+jC7cD3+CSTHW0IgV EHuFcjv2CraTF3wvX8Mph6ivoh1EwW/ycFm2mw8onloUUZaoMHM= =6j9g -----END PGP SIGNATURE----- Merge tag 'asm-generic-6.15-2' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic Pull asm-generic updates from Arnd Bergmann: "This is mainly set of cleanups of asm-generic/io.h, resolving problems with inconsistent semantics of ioread64/iowrite64 that were causing runtime and build issues.
