[LTP] Bug Report: diotest4 fails on mips64

[Hongzhi, Song]

*Ltp:*

latest master


*Kernel:*

After v5.1 ARCH=mips64


*Error info:*

diotest4 10 TBROK : diotest4.c:368: can't mmap file: Invalid argument
diotest4 11 TBROK : diotest4.c:368: Remaining cases broken


I think the first argument of mmap is invalid.

    >shm_base = (char *)(((long)sbrk(0) + (shmsz - 1)) & ~(shmsz - 1));

    >shm_base = mmap(shm_base, 0x100000, PROT_READ | PROT_WRITE,
