include/linux/unaligned/generic.h:5:9: warning: preprocessor token __force redefined
include/linux/compiler.h:10:10: this was the original definition
fixup __force definitions in compat.h code appears to be placed
there as a cover up from a code import from linux when u-boot didn't yet
have a compiler.h, introduced by commit
b1b4e89a0f "Add LZO decompressor support".
