zorro: Fix address space collision message with RAM expansion boards

2020-08-26T11:26:52+00:00

When booting Linux on an Amiga with BigRAMPlus Zorro expansion board: zorro: Address space collision on device Zorro device 12128600 (Individual Computers) [??? 0x50000000-] This happens because the address space occupied by the BigRAMPlus Zorro device is already in use, as it is part of system RAM. Hence the message is harmless. Zorro memory expansion boards have the ERTF_MEMLIST flag set, which tells AmigaOS to link the board's RAM into the free memory list. While we could skip registering the board resource if this flag is set, that may cause issues with Zorro II RAM excluded in a memfile. Hence fix the issue by just ignoring the error if ERTF_MEMLIST is set.

treewide: replace '---help---' in Kconfig files with 'help'

2020-06-13T16:57:21+00:00

Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over '---help---'"), the number of '---help---' has been gradually decreasing, but there are still more than 2400 instances. This commit finishes the conversion. While I touched the lines, I also fixed the indentation. There are a variety of indentation styles found. a) 4 spaces + '---help---' b) 7 spaces + '---help---' c) 8 spaces + '---help---' d) 1 space + 1 tab + '---help---' e) 1 tab + '---help---' (correct indentation) f) 1 tab + 1 space + '---help---' g) 1 tab + 2 spaces + '---help---' In order to convert all of them to 1 tab + 'help', I ran the following commend: $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/' Signed-off-by: Masahiro Yamada

Merge tag 'spdx-5.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/spdx

2020-04-03T20:12:26+00:00

Pull SPDX updates from Greg KH: "Here are three SPDX patches for 5.7-rc1. One fixes up the SPDX tag for a single driver, while the other two go through the tree and add SPDX tags for all of the .gitignore files as needed. Nothing too complex, but you will get a merge conflict with your current tree, that should be trivial to handle (one file modified by two things, one file deleted.) All three of these have been in linux-next for a while, with no reported issues other than the merge conflict" * tag 'spdx-5.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/spdx: ASoC: MT6660: make spdxcheck.py happy .gitignore: add SPDX License Identifier .gitignore: remove too obvious comments

zorro: Replace zero-length array with flexible-array member

2020-03-09T10:12:19+00:00

The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle.

zorro: Move zorro_bus_type to bus-private header file

zorro_bus_type was never used outside the Zorro bus code. Hence move it from the public to the bus-private header file. Signed-off-by: Geert Uytterhoeven Link: https://lore.kernel.org/r/20200112164949.20196-6-geert@linux-m68k.org
