[PATCH v5 0/1] dax: enable dax fault handler to report VM_FAULT_HWPOISON

[Jane Chu]

Change from v4:
Add comments describing when and why dax_mem2blk_err() is used.
Suggested by Dan.

Change from v3:
Prevent leaking EHWPOISON to user level block IO calls such as
zero_range_range, and truncate.  Suggested by Dan.

Change from v2:
Convert EHWPOISON to EIO to prevent EHWPOISON errno from leaking
out to block read(2). Suggested by Matthew.
