293e98256a aarch64, tile: replace struct ucontext with ucontext_t 
glibc >= 2.26 has dropped the tag struct ucontext from ucontext_t type.

* linux/arm/arch_sigreturn.c (arch_sigreturn) [AARCH64]: Replace
struct ucontext with ucontext_t.
* linux/tile/arch_sigreturn.c (arch_sigreturn): Likewise.

43b7c24994 Introduce print_sigset_addr function 
As the definition of NSIG_BYTES is based on NSIG defined in <signal.h>,
NSIG_BYTES cannot be used in files that use kernel sigset_t.

Add another wrapper around print_sigset_addr_len_limit function that
takes one argument less than print_sigset_addr_len wrapper.  This new
wrapper is going to be used in cases when the length argument is equal
to NSIG_BYTES.

* defs.h (print_sigset_addr): New function prototype.
* signal.c (print_sigset_addr): New function.
* linux/alpha/arch_sigreturn.c (arch_sigreturn): Replace
print_sigset_addr_len with print_sigset_addr.
