Rich Felker 4c307bed03 remove x32 syscall timespec fixup hacks ... the x32 syscall interfaces treat timespec's tv_nsec member as 64-bit despite the API type being long and long being 32-bit in the ABI. this is no problem for syscalls that store timespecs to userspace as results, but caused uninitialized padding to be misinterpreted as the high bits in syscalls that take timespecs as input. since the beginning of the port, we've dealt with this situation with hacks in syscall_arch.h, and injected between __syscall_cp_c and __syscall_cp_asm, to special-case the syscall numbers that involve timespecs as inputs and copy them to a form suitable to pass to the kernel. commit 40aa18d55a set the stage for removal of these hacks by letting us treat the "normal" x32 syscalls dealing with timespec as if they're x32's "time64" syscalls, effectively making x32 ax "time64-only 32-bit arch" like riscv32 will be when it's added. since then, all users of syscalls that x32's syscall_arch.h had hacks for have been updated to use time64 syscalls, so the hacks can be removed. there are still at least a few other timespec-related syscalls broken on x32, which were overlooked when the x32 hacks were done or added later. these include at least recvmmsg, adjtimex/clock_adjtime, and timerfd_settime, and they will be fixed independently later on.		2019-07-29 00:19:21 -04:00
