what is the use of drm_os_freebsd.h

[william wallace]

hi ,all
          I am porting something from linux to freebsd ,i found the
DataTypes hard to translate ,then i saw that many types inlinux can be
found in drm_os_freebsd.h,such as
typedef int8_t    s8;
typedef int16_t   s16;
typedef	int32_t   s32;
typedef u_int8_t  u8;
typedef u_int16_t u16;
typedef	u_int32_t u32;

so ,what is the use of  drm_os_freebsd.h
and any advice for me to translate DT from linux to Freebsd?
