Bisect identified commit 33def8498fdd ("treewide: Convert macro and uses
of __section(foo) to __section("foo")"), i.e. the very last commit
before tagging v5.10-rc1.
I can reproduce this with e.g. defconfig and both native s390x build and
build on x86_64 using cross compiler. I used gcc 10.2.1 and binutils 2.34.

Hello Michal,
I've already fixed that. The fix will appear shortly on s390/fixes
Thank you for reporting!

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
Commit 33def8498fdd ("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).
Fixes: 33def8498fdd ("treewide: Convert macro and uses of __section(foo) to __section("foo")")

Apologies and thank you.
I believed the robot had done these compilation tests.
