    asm-generic: Remove unneeded __ARCH_WANT_SYS_LLSEEK macro · caf6f9c8
    Arnd Bergmann authored
    The sys_llseek sytem call is needed on all 32-bit architectures and
    none of the 64-bit ones, so we can remove the __ARCH_WANT_SYS_LLSEEK guard
    and simplify the include/asm-generic/unistd.h header further.
    
    Since 32-bit tasks can run either natively or in compat mode on 64-bit
    architectures, we have to check for both !CONFIG_64BIT and CONFIG_COMPAT.
    
    There are a few 64-bit architectures that also reference sys_llseek
    in their 64-bit ABI (e.g. sparc), but I verified that those all
    select CONFIG_COMPAT, so the #if check is still correct here. It's
    a bit odd to include it in the syscall table though, as it's the
    same as sys_lseek() on 64-bit, but with strange calling conventions.
