These patches add the new I/O resource descriptor 'IORES_DESC_RESERVED' for the iomem resources search interfaces, and in order to make it still work after the new descriptor is added, these codes originally related to 'IORES_DESC_NONE' have been updated. In addition, for the MMCONFIG issue and the SME kdump issue, it is necessary to pass the e820 reserved ranges to kdump kernel. Changes since v1: 1. Modified the value of flags to "0", when walking through the whole tree for e820 reserved ranges. Changes since v2: 1. Modified the value of flags to "0", when walking through the whole tree for e820 reserved ranges. 2. Modified the invalid SOB chain issue. Changes since v3: 1. Dropped [PATCH 1/3 v3] resource: fix an error which walks through iomem resources. Please refer to this commit <010a93bf97c7> "resource: Fix find_next_iomem_res() iteration issue" Changes since v4: 1. Improve the patch log, and add kernel log. Changes since v5: 1.
