Kbuild updates for v4.17 (2nd)
- pass HOSTLDFLAGS when compiling single .c host programs
- build genksyms lexer and parser files instead of using shipped
versions
- rename *-asn1.[ch] to *.asn1.[ch] for suffix consistency
- let the top .gitignore globally ignore artifacts generated by
flex, bison, and asn1_compiler
- let the top Makefile globally clean artifacts generated by
flex, bison, and asn1_compiler
- use safer .SECONDARY marker instead of .PRECIOUS to prevent
intermediate files from being removed
- support -fmacro-prefix-map option to make __FILE__ a relative path
- fix # escaping to prepare for the future GNU Make release
- clean up deb-pkg by using debian tools instead of handrolled
source/changes generation
- improve rpm-pkg portability by supporting kernel-install as a
fallback of new-kernel-pkg
- extend Kconfig listnewconfig target to provide more information
kconfig: extend output of 'listnewconfig'
We at Red Hat/Fedora have generally tried to have a per file breakdown of
every config option we set. This makes it easy for us to add new options
when they are exposed and keep a changelog of why they were set.
A Fedora example is here:
https://src.fedoraproject.org/cgit/rpms/kernel.git/tree/configs/fedora/generic
Using various merge scripts, we build up a config file and run it through
'make listnewconfig' and 'make oldnoconfig'. The idea is to print out new
config options that haven't been manually set and use the default until
a patch is posted to set it properly.
To speed things up, it would be nice to make it easier to generate a
patch to post the default setting. The output of 'make listnewconfig'
has two issues that limit us:
- it doesn't provide the default value
- it doesn't provide the new 'choice' options that get flagged in
'oldconfig'
This patch extends 'listnewconfig' to address the above two issues.
This allows us to run a script
make listnewconfig | rhconfig-tool -o patches; git send-email patches/
The output of 'make listnewconfig':
CONFIG_NET_EMATCH_IPT
CONFIG_IPVLAN
CONFIG_ICE
CONFIG_NET_VENDOR_NI
CONFIG_IEEE802154_MCR20A
CONFIG_IR_IMON_DECODER
CONFIG_IR_IMON_RAW
The new output of 'make listnewconfig':
CONFIG_KERNEL_XZ=n
CONFIG_KERNEL_LZO=n
CONFIG_NET_EMATCH_IPT=n
CONFIG_IPVLAN=n
CONFIG_ICE=n
CONFIG_NET_VENDOR_NI=y
CONFIG_IEEE802154_MCR20A=n
CONFIG_IR_IMON_DECODER=n
CONFIG_IR_IMON_RAW=n
