net: remove ax25 and amateur radio (hamradio) subsystem

2026-04-23T17:24:02+00:00

Remove the amateur radio (AX.25, NET/ROM, ROSE) protocol implementation and all associated hamradio device drivers from the kernel tree. This set of protocols has long been a huge bug/syzbot magnet, and since nobody stepped up to help us deal with the influx of the AI-generated bug reports we need to move it out of tree to protect our sanity. The code is moved to an out-of-tree repo: https://github.com/linux-netdev/mod-orphan if it's cleaned up and reworked there we can accept it back. Minimal stub headers are kept for include/net/ax25.h (AX25_P_IP, AX25_ADDR_LEN, ax25_address) and include/net/rose.h (ROSE_ADDR_LEN) so that the conditional integration code in arp.c and tun.c continues to compile and work when the out-of-tree modules are loaded.

lib/crc: remove unnecessary prompt for CONFIG_CRC_ITU_T

2025-04-04T18:31:42+00:00

All modules that need CONFIG_CRC_ITU_T already select it, so there is no need to bother users about the option. Reviewed-by: Christoph Hellwig Reviewed-by: "Martin K.

lib/crc32: remove obsolete CRC32 options from defconfig files

2025-02-09T04:06:30+00:00

Remove all remaining references to CONFIG_CRC32_BIT, CONFIG_CRC32_SARWATE, CONFIG_CRC32_SLICEBY4, and CONFIG_CRC32_SLICEBY8. These options no longer exist, now that we've standardized on a single generic CRC32 implementation.

treewide: drop CONFIG_EMBEDDED

2023-08-21T20:46:25+00:00

There is only one Kconfig user of CONFIG_EMBEDDED and it can be switched to EXPERT or "if !ARCH_MULTIPLATFORM" (suggested by Arnd).

mips: update config files

2022-09-30T14:45:06+00:00

Clean up config files by: - removing configs that were deleted in the past - removing configs not in tree and without recently pending patches - adding new configs that are replacements for old configs in the file For some detailed information, see Link.

configs: remove the obsolete CONFIG_INPUT_POLLDEV

2021-09-08T18:50:28+00:00

This CONFIG option was removed in commit 278b13ce3a89 ("Input: remove input_polled_dev implementation") so there's no point to keep it in defconfigs any longer. Get rid of the leftover for all arches.

MIPS: configs: Cleanup old Kconfig options

2020-02-19T18:48:27+00:00

CONFIG_MTD_NAND_IDS is gone and not needed (part of CONFIG_MTD_NAND) since commit f16bd7ca0457 ("mtd: nand: Kill the MTD_NAND_IDS Kconfig option"). CONFIG_IOSCHED_DEADLINE, CONFIG_IOSCHED_CFQ and CONFIG_DEFAULT_NOOP are gone since commit f382fb0bcef4 ("block: remove legacy IO schedulers"). The IOSCHED_DEADLINE was replaced by MQ_IOSCHED_DEADLINE and it will be now enabled by default (along with MQ_IOSCHED_KYBER). The BFQ_GROUP_IOSCHED is the only multiqueue scheduler which comes with group scheduling so select it in configs previously choosing CFQ_GROUP_IOSCHED.

MIPS: configs: Remove useless UEVENT_HELPER_PATH

2019-06-11T22:46:21+00:00

Remove the CONFIG_UEVENT_HELPER_PATH because: 1. It is disabled since commit 1be01d4a5714 ("driver: base: Disable CONFIG_UEVENT_HELPER by default") as its dependency (UEVENT_HELPER) was made default to 'n', 2. It is not recommended (help message: "This should not be used today [...] creates a high system load") and was kept only for ancient userland, 3. Certain userland specifically requests it to be disabled (systemd README: "Legacy hotplug slows down the system and confuses udev").

MIPS: Regenerate defconfigs

A couple of patches have come up recently to remove particular instances of obsolete Kconfig symbols from defconfigs. Rather than doing this piecemeal, simply regenerate them all.
