What problem is this fixing?
I.e. one is supposed to include <linux/mman.h>, get the
tools/include/uapi/linux/mman.h and it in turn will include the per-arch
mman.h, say tools/arch/sparc/include/uapi/asm/mman.h, that in turn will
include uapi/asm-generic/mman-common.h after defining its diverging
bits.
Some, like the ones for the Alpha and MIPS architectures, will not even
include mman-common.h, so diverging they are.
Lots of arches, like s390, will just include uapi/asm-generic/mman.h
from its mman.h file (tools/arch/s390/include/uapi/asm/mman.h), just
like you'd do for _all_ arches in your patch below.
tools/perf/Makefile.config is the one doing:
INC_FLAGS += -I$(srctree)/tools/arch/$(ARCH)/include/
and:
[acme@jouet linux]$ ls tools/arch/*/include/uapi/asm/mman.h
tools/arch/alpha/include/uapi/asm/mman.h
tools/arch/ia64/include/uapi/asm/mman.h

Am I missing something?
