Hi all!
In my attempt to write my first useful kernel patch, I'm tracking down
a possibly kernel regression on my laptop's wireless driver. I'm
trying to use git bisect to narrow down the problem and I'm having
trouble compiling a Linux kernel 4.14 from Linus tree in my Arch
Linux.
The error I'm getting is "Unsupported relocation type: R_X86_64_PLT32"
I have read about gcc enabling -fPIC by default from gcc-6 so I have
tried compiling with gcc-{8,7,5,4.9} with and without
"-fno-pic -no-pic" by running
make CC="gcc-5 -fno-pic -no-pic"
with no luck. I was expecting those R_X86_64_PLT32 relocations not to
be generated with this options but there is something I have still not
understood.
I have been able to compile the kernel after applying greg's stable
tree patch [1] (and [2,3] for gcc-8) but the kernel refuses to boot.
Any help/comments on either the problem or the followed methodology will be
appreciated!
Thank you! :D

Sorry, I meant "-fno-pie -no-pie" instead of "-fno-pic -no-pic"

Hi Aleix,
> (reminder just in case the email was missed!)
When you post queries/bug reports then you should always Cc
maintainers and subsystem specific
mailing lists.
You can can find maintainers and mailings lists by:
$ cd /path to your kernel source/
$ ./scripts/get_maintainer.pl /path to your wireless driver file
Thanks a lot,
Shyam

Hi Shyam,
Sorry, I think I have not made myself clear enough. The error that
doesn't let me sleep at night,
> "Unsupported relocation type: R_X86_64_PLT32"
it is not related at all with my wireless driver. This error pops up
when compiling a Linux Kernel 4.14 from Linus tree with
gcc-{8,7,5,4.9}. The reason of why I'm compiling a linux kernel 4.14
is to identify a commit which introduced a possible regression in my
wireless driver.
To provide some more context, I'm adding the full compile report in
the following links:
Linux 4.14 (+ patches [2,3]) build with gcc-8.2.1
https://drive.google.com/open?id=1tg0iR3dirhW4MhU_3RXcNyvmiJ-j6nBy
Linux 4.14 vanilla build with gcc-4.9.4
https://drive.google.com/open?id=1YJIpVc5VA1xpblQQxHSzrWhTArl5lTKQ
I have already spent too many hours in this detail, so any hint is welcomed :)
Thank you!
