Subject: [PATCH v1 0/2] swiotlb: Cleanup and alignment fix

From: Petr Tesarik <petr.tesarik.ext@...wei.com>

While working on the dynamic SWIOTLB, I noticed a couple of issues
with the current implementation.

This patch series should be applied on top of GuoRui.Yu's fix for
the deadlock in swiotlb_do_find_slots().

Petr Tesarik (2):
  swiotlb: Use wrap_area_index() instead of open-coding it
  swiotlb: Fix slot alignment checks
