    s390: correct __bootdata / __bootdata_preserved macros · 8e90b4b1
    Vasily Gorbik authored
    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 33def849 ("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: 33def849 ("treewide: Convert macro and uses of __section(foo) to __section("foo")")
