[PATCH 1/1] swiotlb: save io_tlb_used to local variable before leaving critical section

When swiotlb is full, the kernel would print io_tlb_used. However, the result might be inaccurate at that time because we have left the critical section protected by spinlock. Therefore, we backup the io_tlb_used into local variable before leaving critical section. Fixes: 83ca25948940 ("swiotlb:

[PATCH] iommu/amd: Set exclusion range correctly

From: Joerg Roedel The exlcusion range limit register needs to contain the base-address of the last page that is part of the range, as bits 0-11 of this register are treated as 0xfff by the hardware for comparisons. So correctly set the exclusion range in the hardware to the last page which is _
