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 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"
