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. Rewrite these patches log. Changes since v6: 1. Modify the [PATCH 1/2], and add the new I/O resource descriptor 'IORES_DESC_RESERVED' for the iomem resources search interfaces, and also updates these codes relates to 'IORES_DESC_NONE'. 2. Modify the [PATCH 2/2], and walk through io resource based on the new descriptor 'IORES_DESC_RESERVED'. 3. Update patch log. Changes since v7: 1. Improve patch log. 2. Improve this function __ioremap_check_desc_other(). 3. Modify code comment in the __ioremap_check_desc_other() Changes since v8: 1. Get rid of all changes about ia64.(Borislav's suggestion) 2. Change the examination condition to the 'IORES_DESC_ACPI_*'. 3. Modify the signature. This patch(add the new I/O resource descriptor 'IORES_DESC_RESERVED') was suggested by Boris. Changes since v9: 1. Improve patch log. 2. No need to modify the kernel/resource.c, so correct them. 3. Change the name of the __ioremap_check_desc_other() to __ioremap_check_desc_none_and_reserved(), and modify the check condition, add comment above it. Changes since v10: 1. Split them into three patches, the second patch is currently added. 2. Change struct ioremap_mem_flags to struct ioremap_desc and redefine it. 3. Change the name of the __ioremap_check_desc_other() to __ioremap_check_desc(). 4. Change the check condition in SEV and also improve them. 5. Modify the return value for some functions.
