Currently s390 build is broken. SECTCMP .boot.data error: section .boot.data differs between vmlinux and arch/s390/boot/compressed/vmlinux make[2]: *** [arch/s390/boot/section_cmp.boot.data] Error 1 SECTCMP .boot.preserved.data error: section .boot.preserved.data differs between vmlinux and arch/s390/boot/compressed/vmlinux make[2]: *** [arch/s390/boot/section_cmp.boot.preserved.data] Error 1 make[1]: *** [bzImage] Error 2 Commit33def8498f("treewide: Convert macro and uses of __section(foo) to __section("foo")") converted all __section(foo) to __section("foo"). This is wrong for __bootdata / __bootdata_preserved macros which want variable names to be a part of intermediate section names .boot.data.<var name> and .boot.preserved.data.<var name>. Those sections are later sorted by alignment + name and merged together into final .boot.data / .boot.preserved.data sections. Those sections must be identical in the decompressor and the decompressed kernel (that is checked during the build).

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
