> This patch fixes a bug under lower version linux kernel, mmap()
> fails when length is not aligned with hugepage size. mmap()
> without flag of MAP_ANONYMOUS, should be called with length
> argument aligned with hugepagesz at older longterm version
> Linux, like 2.6.32 and 3.2.72, or mmap() will fail with EINVAL.
> This bug was fixed in Linux kernel by commit:
> dab2d3dc45ae7343216635d981d43637e1cb7d45
> To avoid failure, make sure in caller to keep length aligned.
> 
> v3 changes:
>  - fix (u64) -> (void *) convert error on 32-bit system
> 
> v2 changes:
>  - add Kernel version comments and commit msg
>  - remove unnecessary alignments when munmap

You forgot to keep Huawei's ack from v2.
