Subject: linux-next: build failure after merge of the akpm-current tree

Hi Andrew,

After merging the akpm tree, today's linux-next build (powerpc
pseries_le_defconfig) failed like this:

powerpc-linux-ld: arch/powerpc/purgatory/purgatory.o: compiled for a big endian system and target is little endian  
powerpc-linux-ld: failed to merge target specific data of file arch/powerpc/purgatory/purgatory.o
powerpc-linux-ld: arch/powerpc/purgatory/printf.o: compiled for a big endian system and target is little endian
powerpc-linux-ld: failed to merge target specific data of file arch/powerpc/purgatory/printf.o

and so on ...

Presumably caused by commit

  b26db279958b ("powerpc: add purgatory for kexec_file_load implementation")

I added this patch for today:
