Hello All,

Is traditional signal support, enabled by the flag CONFIG_TRAD_SIGNALS proscribed in 64-bit mode ?

In arch/mips/kernel/signal.c, functions sys_sigsuspend(), sys_sigaction(), sys_sigreturn(), setup_frame() are conditionally compiled, depending on whether the flag CONFIG_TRAD_SIGNALS is defined or not. If one defines the constant, the compilation fails as the constants such as __NR_sigreturn are not defined in asm-mips/unistd.h for 64-bit mips.


Does it mean that only realtime signals are supposed to be used in 64-bit mode ?

thank you,
Prasad.
