[PATCH 0/1] introduce ioremap_wc()

[Yunhui Cui]

Compared with IO attributes, NC attributes can improve performance,
specifically in these aspects: Relaxed Order, Gathering, Supports Read
Speculation, Supports Unaligned Access.

When I replied to this patch (https://lore.kernel.org/all/CAEEQ3wmVPrZ6s8msM8RgcyZePGhXM1ikYMc5wW2n8q3Bf90EVw@mail.gmail.com/),
I found the author's email address was invalid. So, based on this patch,
I made slight modifications and resubmitted it.
