* net: handle HAS_IOPORT dependenciesNiklas Schnelle2024-04-081-3/+3
| | | | | | | | | | | | | | | | | In a future patch HAS_IOPORT=n will disable inb()/outb() and friends at compile time. We thus need to add HAS_IOPORT as dependency for those drivers requiring them. For the DEFXX driver the use of I/O ports is optional and we only need to fence specific code paths. It also turns out that with HAS_IOPORT handled explicitly HAMRADIO does not need the !S390 dependency and successfully builds the bpqether driver.

* hamradio: baycom: remove useless link in KconfigPeter Lafreniere2023-09-221-8/+7
| | | | | | | | | | | | | | The Kconfig help text for baycom drivers suggests that more information on the hardware can be found at <https://www.baycom.de>. The website now includes no information on their ham radio products other than a mention that they were once produced by the company, saying: "The amateur radio equipment is now no longer part and business of BayCom GmbH" As there is no information relavent to the baycom driver on the site, remove the link.

* hamradio: drop ISA_DMA_API dependencyArnd Bergmann2023-04-191-1/+1
| | | | | | | | | It looks like the dependency got added accidentally in commit a553260618d8 ("[PATCH] ISA DMA Kconfig fixes - part 3"). Unlike the previously removed dmascc driver, the scc driver never used DMA. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: David S. Miller <davem@davemloft.net>

* dmascc: add CONFIG_VIRT_TO_BUS dependencyArnd Bergmann2021-09-281-0/+1
| | | | | | | | | | | | | | | | | | | | | Many architectures don't define virt_to_bus() any more, as drivers should be using the dma-mapping interfaces where possible: In file included from drivers/net/hamradio/dmascc.c:27: drivers/net/hamradio/dmascc.c: In function 'tx_on': drivers/net/hamradio/dmascc.c:976:30: error: implicit declaration of function 'virt_to_bus'; did you mean 'virt_to_fix'?

* treewide: replace '---help---' in Kconfig files with 'help'Masahiro Yamada2020-06-141-8/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | 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 <masahiroy@kernel.org>

* tty: Added a CONFIG_TTY option to allow removal of TTYJoe Millenbach2013-01-181-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The option allows you to remove TTY and compile without errors. This saves space on systems that won't support TTY interfaces anyway. bloat-o-meter output is below. The bulk of this patch consists of Kconfig changes adding "depends on TTY" to various serial devices and similar drivers that require the TTY layer. Ideally, these dependencies would occur on a common intermediate symbol such as SERIO, but most drivers "select SERIO" rather than "depends on SERIO", and "select" does not respect dependencies. bloat-o-meter output comparing our previous minimal to new minimal by removing TTY. The list is filtered to not show removed entries with awk '$3 != "-"' as the list was very long. add/remove: 0/226 grow/shrink: 2/14 up/down: 6/-35356 (-35350) function old new delta chr_dev_init 166 170 +4 allow_signal 80 82 +2 static.__warned 143 142 -1 disallow_signal 63 62 -1 __set_special_pids 95 94 -1 unregister_console 126 121 -5 start_kernel 546 541 -5 register_console 593 588 -5 copy_from_user 45 40 -5 sys_setsid 128 120 -8 sys_vhangup 32 19 -13 do_exit 1543 1526 -17 bitmap_zero 60 40 -20 arch_local_irq_save 137 117 -20 release_task 674 652 -22 static.spin_unlock_irqrestore 308 260 -48 Signed-off-by: Joe Millenbach <jmillenbach@gmail.com> Reviewed-by: Jamey Sharp <jamey@minilop.net> Reviewed-by: Josh Triplett <josh@joshtriplett.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
