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).
