Subject: s390: correct __bootdata / __bootdata_preserved macros
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")")
