The INITCONST macro is defined here in the kernel path (the #else
branch of #ifdef STATIC), but the pre-boot path earlier in this
header only defines INIT:

include/linux/decompress/mm.h:
    #ifdef STATIC
    ...
    #define INIT

Should INITCONST also be defined in the pre-boot path for
consistency? The individual decompressor files (decompress_inflate.c,
decompress_bunzip2.c, etc.) all include this header and are compiled
in both contexts. If any of them later uses INITCONST for a const
array following the pattern in lib/decompress.c, the pre-boot build
would fail with an undefined macro.
