m68k: Add asm/config.h

2022-02-21T11:00:20+00:00

To avoid 'warning: no previous prototype for' errors, declare all the
parse_bootinfo and config function prototypes into asm/config.h and
include it in arch/m68k/kernel/setup_mm.c and arch/m68k/*/config.c.

block: remove genhd.h

2022-02-02T14:49:59+00:00

There is no good reason to keep genhd.h separate from the main blkdev.h
header that includes it.  So fold the contents of genhd.h into blkdev.h
and remove genhd.h entirely.

m68k/q40: Replace q40ide driver with pata_falcon and falconide

2021-06-10T22:30:12+00:00

This allows m68k q40 systems to switch from the deprecated IDE subsystem
to libata.

Enhance the byte-swapping falconide and pata_falcon platform drivers to
accept an irq resource, for use on q40. Atari ST-DMA IRQ arrangements seem
to co-exist with q40 IRQ arrangements without too much mess.

The new IO resources were added solely for the purpose of making
request_region() reservations identical to those made by q40ide: these
regions aren't used for actual IO.

treewide: remove editor modelines and cruft

2021-05-07T07:26:34+00:00

The section "19) Editor modelines and other cruft" in
Documentation/process/coding-style.rst clearly says, "Do not include any
of these in source files."

I recently receive a patch to explicitly add a new one.

Let's do treewide cleanups, otherwise some people follow the existing code
and attempt to upstream their favoriate editor setups.

It is even nicer if scripts/checkpatch.pl can check it.

If we like to impose coding style in an editor-independent manner, I think
editorconfig (patch [1]) is a saner solution.
