RISC-V: Use 64-bit-time syscall numbers with the 32-bit port
sysdep.h redefines only the syscall where the generic implementation still does not have actual 64-bit time_t support: /* Workarounds for generic code needing to handle 64-bit time_t. */ /* Fix sysdeps/unix/sysv/linux/clock_getcpuclockid.c. */ #define __NR_clock_getres __NR_clock_getres_time64 /* Fix sysdeps/nptl/lowlevellock-futex.h. */ #define __NR_futex __NR_futex_time64 [...] This patch also adds a comment that it is a workaround to handle 64-bit time_t and on each #define comment for which implementation it intends to.
