    Subject[RFC] [PATCH] asm-generic/unistd.h: handle symbol prefixes in cond_syscall
    Some architectures have symbol prefixes and set CONFIG_SYMBOL_PREFIX,
    but this wasn't taken into account by the generic cond_syscall. It's
    easy enough to fix in a generic fashion, so add the symbol prefix to
    symbol names in cond_syscall when CONFIG_SYMBOL_PREFIX is set.
