Subject: [PATCH 0/8] add generic builtin command line
Date: Thu, 27 Sep 2018 19:55:08 +0300 [thread overview]
Message-ID: <1538067309-5711-1-git-send-email-maksym.kokhan@globallogic.com> (raw)
There were series of patches [1] for 4.3.0-rc3, that allowed
architectures to use a generic builtin command line. I have rebased
these patches on kernel 4.19.0-rc4.
Things, modified in comparison with original patches:
* There was some bug for mips, in the case when CONFIG_CMDLINE_PREPEND
and CONFIG_CMDLINE_APPEND are empty and CMDLINE_OVERRIDE is not set,
command line from bootloader was ignored, so I fixed it, modifying
patch "add generic builtin command line".
* Implemented new patch to resolve conflict with new kernel, which
modify EFI stub code. Unfortunately, I don't have capability to test
this modification on real arm board with EFI.
* Removed new realisation of mips builtin command line, which was
created after 4.3.0-rc3.
* Kernel 4.3.0-rc3 with original patches could not be compiled for
powerpc due to prom_init.c checking by prom_init_check.sh. So I added
strlcat (which is used by cmdline_add_builtin macro) to
prom_init_check.sh whitelist.
Patches have been tested in QEMU for x86, arm (little-endian), arm64
(little-endian), mips (little-endian, 32-bit) and powerpc
(big-endian, 64-bit), everything works perfectly. Also it was tested
on linux-next (next-20180924 tag) for all listed above architectures.
