[PATCH 0/4] Fix a segmentation fault also add raid6test for RISC-V support

[Chunyan Zhang]

The first two patches are fixes. 
The last two are for userspace raid6test support on RISC-V.

The issue fixed in patch 2/4 was probably the same which was spotted by
Charlie [1], I couldn't reproduce it at that time.

When running raid6test in userspace on RISC-V, I saw a segmentation fault,
I used gdb command to print pointer p, it was an unaccessible address.

With patch 2/4, the issue didn't appear anymore.
