makes it an exclusive device tree subarchitecture without any special weirdness in arch/arm/mach-ixp4xx. The biggest noticeable change is the removal of the old PCI driver and along with that the removal of the special DMA coherency code and defines and the DMA bouncing. I tried to convert the IXP4xx to multiplatform on top of this but it didn't work because IXP4xx wants to be big endian and multiplatform config creates a problem like this: ../arch/arm/kernel/head.S: Assembler messages: ../arch/arm/kernel/head.S:94: Error: selected processor does not support `setend be' in ARM mode I think this is because MULTI_V5 turns on CPUs that cannot do big endian, and IXP4xx turn on big endian. (It crashes if I try to boot in little endian mode, sorry. It really wants to run big endian.) But before fixing multiplatform we can fix all of this! The networking patches are dependencies so I am requesting ACKs from the network maintainers on these. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEElDRnuGcz/wPCXQWMQRCzN7AZXXMFAmIH7KsACgkQQRCzN7AZ XXNGDQ//dfQIiKC0uE4UEbKeDG18c1NpSDHomQQ/xGjnl9nenmOzsqg9pu+hrD+y eHNp55PmL8WKjXYV8wrbQd65BsnMGpiIh4CoT17BOM0vjQ7+l0KM9FqCuYTIXkyE +AR8ZbOYZDSNZA6bKCy8dT1tYZakx2IK02YEphiAU2hPsvWYTE2VTDSYzskbW7pu +aaCzPOnteQZM4cRMPDOmhq9FedaCnluom9ldTei0nEkFuDi0v947zUVs8M3o7gi rsZBRxfXlY86G3b8WdqL0jCcrsWsnLnP6TehSH7r/TbsFlzdv+GQpfZ8craDpTTW X5zhUQYreAYNY88Vy1UoVSci6BSJF/c8Q75lcLOcIuf/XX6ufyTO1YHDXxxSm04P 1cjunZzJs/YGx2dDgVfzSIXTBCMKovZcUVI5FfEP36wW3RA1WSa4cdWnI9alwlp4 yX7AtOtbxIZ2jiNQMV4qx9Yz8SzlVWF7E63S16XAiFWr8BQex1Lmh2u5BZLE03XW k9yl+dhqmTf+MlHS7y70KdwxY0XvJNZiHoCEIA2A0B7ayvl9ThkXOWOkYBZLb0hq SmlIHJkRyFLNxtVTvadq3S8fa1haS9qTONwfS7KCkCPp8XpE4QCDCEAOK9EK0tCS p4SRGKD6SpoqEZKVItacGfLLAjJeGt6kIDBdRJ0J/nASVgcvaT8= =DMVU -----END PGP SIGNATURE----- gpgsig -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEo6/YBQwIrVS28WGKmmx57+YAGNkFAmIY9nQACgkQmmx57+YA GNkM8RAAqwYUKHl1pkAnTBU60aW9dWJpNdyIej22sdi+FcsGcF4tC/RQ+Zssl0VD eMvAM295eGZDb02B0f8EbPQHuDEp7Y9mpC+9QjoBCLCojho15ise3cKmyloG9/7T xo1J99lY/PW7ociVXqO4rZtWsplgy+FB3X+cCsk/UziwsF+HqjSSOi9VsEkHsBHI sJwDE90YetuC3S2+5/G9z2JbuqNchGebT66ZE13CGGBLb1cKBNMb2L1ZjwRlbhUK tYPBaTBnwJApLKoTQx4HlpAei5XROEB/3qxPH4e4RnW8MZyG7+ZNXnkIuZytJxVc zt5Qols2bLakHms0QdZhpeinvqPV4c88xGCZryQRHqbU1VLfygFFuoqnDfn/l0vW KWceaSMeL5EpvE+1sZsP7EcQn5AhCKckWoaL3TRJzeR/0JJswgBMMSBYof/eSP4u jJX+NBid6Hjred7B12QBFYc7L3LCDcmFmQM9LYa7IciedRx3fqw9yNRXzBVgTUDC t/cuLn06uLYTbn5fNnxxRvvDkLnXtf8OyzER0fy+Dm+terjIMATK3iQ0bGvwj46Y sQ74A7mQ+tsosmS+SEz79VD3AuzCqm3nfFTeU8W0QUj3IK1zqWKEjmJpeeniuL8L QBP7ZR8wlytfwq4fm2gI3wss1gFw8GYcJlkPhBAuHjMisiFWl10= =blMU -----END PGP SIGNATURE----- Merge tag 'ixp4xx-cleanup-for-v5.18' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-nomadik into arm/soc This cleans out the remaining board files from IXP4xx and makes it an exclusive device tree subarchitecture without any special weirdness in arch/arm/mach-ixp4xx.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
