Copy include/linuxlimits.h from Linux 5.1-rc1
(removing #include <uapi/linux/limits.h>).
While we are here, add SPDX License tag to <linux/kernel.h>.
Based on the following Linux commits:
- 54d50897d544 ("linux/kernel.h: split *_MAX and *_MIN macros
into <linux/limits.h>")
- 2dc0e68d5ada ("linux/kernel.h: use 'short' to define USHRT_MAX,
SHRT_MAX, SHRT_MIN")
