In the Linux kernel, the following vulnerability has been resolved:

powerpc/pseries/iommu: IOMMU incorrectly marks MMIO range in DDW

Power Hypervisor can possibily allocate MMIO window intersecting with Dynamic DMA Window (DDW) range, which is over 32-bit addressing.

These MMIO pages needs to be marked as reserved so that IOMMU doesn't map DMA buffers in this range.

The current code is not marking these pages correctly which is resulting in LPAR to OOPS while booting. The stack is at below

There are 2 issues in the code

1. The index is "int" while the address is "unsigned long". This results in negative value when setting the bitmap.

2. The DMA offset is page shifted but the MMIO range is used as-is (64-bit address). MMIO address needs to be page shifted as well.
