[PATCH v2 2/2] x86_64: enable SWIOTLB if system has SRAT memory regions above MAX_DMA32_PFN

when memory hotplug enabled system is booted with less than 4GB of RAM and then later more RAM is hotplugged 32-bit devices stop functioning with following error: nommu_map_single: overflow 327b4f8c0+1522 of device mask the reason for this is that if x86_64 system were booted with RAM l

[PATCH v2 1/2] x86: introduce max_possible_pfn

max_possible_pfn will be used for tracking max possible PFN for memory that isn't present in E820 table and could be hotplugged later. By default max_possible_pfn is initialized with max_pfn, but a follow up patch will update it with highest PFN of hotpluggable memory ranges declared in ACPI SRAT

[PATCH v2 0/2] x86: enable SWIOTLB if system has SRAT memory regions above MAX_DMA32_PFN

changes since v1: - reduce # of #ifdefs by introducing max_possible_pfn global variable - don't check 'acpi_no_memhotplug=1' for disabling SWIOTLB initialization, since existing 'no_iommu' kernel option could be used to the same effect. - split into 2 patches - 1st adds max_
