[uml-devel] [PATCH 3/6] uml: remove old UM_FASTCALL, and make the thing work again

["Paolo 'Blaisorblade' Giarrusso" <blaisorblade@yahoo.it>]

From: Paolo 'Blaisorblade' Giarrusso <blaisorblade@yahoo.it>

This was used in the old dark age of 2.4, ARCH_CFLAGS doesn't work any more
since some time, and UM_FASTCALL was never used in 2.6.

Instead, reintroduce the thing more properly now, directly in
include/asm-um/linkage.h.

Signed-off-by: Paolo 'Blaisorblade' Giarrusso <blaisorblade@yahoo.it>
