---------------------------

Following patches of the series introduce ILP32-specific structures and
handlers for signal subsystem. In this patch, functions and structures
that common for LP64 and ILP32 are moved to
arch/arm64/include/asm/signal_common.h to let ILP32 code reuse them. Some
functions work with struct rt_sigframe which differs for ILP32. Therefore,
to let ILP32 generate correct code, body of that functions are moved to
arch/arm64/include/asm/signal_common.h. Others just declared in new header.
