Subject: [PATCH 00/12] tools/nolibc: always use 64-bit ino_t, off_t and
 time-related types

nolibc currently uses 32-bit types for various APIs. These are
problematic as their reduced value range can lead to truncated values.

Thomas Weißschuh (12):
      tools/nolibc: use 64-bit ino_t
      tools/nolibc: handle 64-bit off_t for llseek
      tools/nolibc: prefer the llseek syscall
      tools/nolibc: use 64-bit off_t
      tools/nolibc: remove now superfluous overflow check in llseek
      tools/nolibc: remove more __nolibc_enosys() fallbacks
      tools/nolibc: prefer explicit 64-bit time-related system calls
      tools/nolibc: gettimeofday(): avoid libgcc 64-bit divisions
      tools/nolibc: use a custom struct timespec
      tools/nolibc: always use 64-bit time types
      selftests/nolibc: test compatibility of timespec and __kernel_timespec
      tools/nolibc: remove time conversions
