Passing 64-bit arguments on syscalls.list is tricky: it requires to reimplement the expected kernel abi in each architecture. This is way to better to represent in C code where we already have macros for this (SYSCALL_LL64). Checked on x86_64-linux-gnu. |

README
This hierarchy supports Linux systems using the new asm-generic/unistd.h, which removes many familiar old syscalls. For example, to implement open(), newer Linux architectures require glibc to invoke the __NR_openat syscall with AT_FDCWD. This hierarchy provides all those implementations. It also provides support for 32-bit platforms using the 64-bit kernel syscall APIs, as the 32-bit ones are no longer provided. Note that newer ILP32 environments (x32 or AArch64:ILP32, for example) are converting to use more 64-bit types in kernel syscalls, so that aspect of this support is in more flux as of this writing.
