I see a few "inline" references to the .txt file in -rc4 (see below):
I am not sure if you managed to update them too.

./arch/microblaze/include/asm/cacheflush.h:/* Look at Documentation/cachetlb.txt */
./arch/unicore32/include/asm/cacheflush.h: *	See Documentation/cachetlb.txt for more information.
./arch/arm64/include/asm/cacheflush.h: *	See Documentation/cachetlb.txt for more information. Please note that
./arch/arm/include/asm/cacheflush.h: *	See Documentation/cachetlb.txt for more information.
./arch/xtensa/include/asm/cacheflush.h: * (see also Documentation/cachetlb.txt)
./arch/xtensa/include/asm/cacheflush.h:/* This is not required, see Documentation/cachetlb.txt */
