[PATCH v2 0/7] Introduce struct __kernel_timex

[Deepa Dinamani <deepa.kernel@gmail.com>]

The series introduces struct __kernel_timex as a substitute for
the non y2038 safe struct timex.

The series is based on the original series posted by Arnd Bergmann
in [1].

The overview of the series is as below:
1. Prepare for the compat timex interfaces to be used unconditionally.
2. Introduce struct __kernel_timex.
3. Use struct __kernel_timex in place of struct timex.
4. Switch syscalls to use struct __kernel_timex.

Changes since v1:
* Fix riscv asm/compat.h to pick up generic compat types

Deepa Dinamani (7):
  arm64: Make basic compat_* types always available
  sparc: Make thread_info.h available directly
  riscv: Include asm-generic/compat.h
  timex: prepare compat helpers for y2038 changes
  time: Add struct __kernel_timex
  timex: use __kernel_timex internally
  timex: change syscalls to use struct __kernel_timex
