QEMU sees that header indirectly via sys/socket.h In linux kernel commit 0768e17073dc527ccd18ed5f96ce85f9985e9115 the asm-generic/sockios.h header no longer defines SIOCGSTAMP. Instead it provides only SIOCGSTAMP_OLD, which only uses a 32-bit time_t on 32-bit architectures. The linux/sockios.h header then defines SIOCGSTAMP using either SIOCGSTAMP_OLD or SIOCGSTAMP_NEW as appropriate. If SIOCGSTAMP_NEW is used, then the tv_sec field is 64-bit even on 32-bit architectures To cope with this we must now define two separate syscalls, with corresponding old and new sizes, as well as including the new linux/sockios.h header.
