Saner transition plan for GENERIC_SIGALTSTACK conversion - instead of adding #define sys_sigaltstack sys_sigaltstack in asm/syscalls.h of architecture if it's pulls asm-generic/syscalls.h, only to have those defines removed once all architectures are converted, make the declaration in said asm-generic/syscalls.h conditional on the lack of GENERIC_SIGALTSTACK. Less messy in intermediate stages that way...
