char: Replace HTTP links with HTTPS ones

2020-07-23T07:44:15+00:00

Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`: If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.

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

powerpc: Remove Xilinx PPC405/PPC440 support

2020-05-28T13:24:34+00:00

The latest Xilinx design tools called ISE and EDK has been released in October 2013. New tool doesn't support any PPC405/PPC440 new designs. These platforms are no longer supported and tested. PowerPC 405/440 port is orphan from 2013 by commit cdeb89943bfc ("MAINTAINERS: Fix incorrect status tag") and commit 19624236cce1 ("MAINTAINERS: Update Grant's email address and maintainership") that's why it is time to remove the support fot these platforms.

rtc/alpha: remove legacy rtc driver

2020-03-19T06:41:02+00:00

The old drivers/char/rtc.c driver was originally the implementation for x86 PCs but got subsequently replaced by the rtc class driver on all architectures except alpha. Move alpha over to the portable driver and remove the old one for good. The CONFIG_JS_RTC option was only ever used on SPARC32 but has not been available for many years, this was used to build the same rtc driver with a different module name.

rtc/ia64: remove legacy efirtc driver

2020-03-19T06:41:02+00:00

There are two EFI RTC drivers, the original drivers/char/efirtc.c driver and the more modern drivers/rtc/rtc-efi.c. Both implement the same interface, but the new one does so in a more portable way. Move everything over to that one and remove the old one.

tty: source all tty Kconfig files in one place

2020-03-12T16:17:30+00:00

'source' (include) all of the tty/*/Kconfig files from drivers/tty/Kconfig instead of from drivers/char/Kconfig. This consolidates them both in source code and in menu presentation to the user. Move hvc/Kconfig and serial/Kconfig 'source' lines into the if TTY/endif block and remove the if TTY/endif blocks from those 2 files.

char: group dev configs togther

2020-03-12T16:17:29+00:00

Group /dev/{mem,kmem,nvram,raw,port} driver configs together. This also means that tty configs are now grouped together instead of being split up. This just moves Kconfig lines around. There are no other changes.

random: Make RANDOM_TRUST_CPU depend on ARCH_RANDOM

2020-02-28T04:21:52+00:00

Listing the set of host architectures does not scale. Depend instead on the existence of the architecture rng. This will allow RANDOM_TRUST_CPU to be selected on arm64. Today ARCH_RANDOM is only selected by x86, s390, and powerpc, so this does not adversely affect other architectures.
