asm-generic: Make time32 syscall numbers optional
We don't want new architectures to even provide the old 32-bit time_t based system calls any more, or define the syscall number macros. Add a new __ARCH_WANT_TIME32_SYSCALLS macro that gets enabled for all existing 32-bit architectures using the generic system call table, so we don't change any current behavior. Since this symbol is evaluated in user space as well, we cannot use a Kconfig CONFIG_* macro but have to define it in uapi/asm/unistd.h. On 64-bit architectures, the same system call numbers mostly refer to the system calls we want to keep, as they already pass 64-bit time_t. As new architectures no longer provide these, we need new exceptions in checksyscalls.sh. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
