Shiraz Hashim 2f879b6dcb mm/memblock: fix a race between search and remove ... no-map-fixup feature for dma-removed reserve region does a late memblock remove. This late removal is a slight deviation from conventional memblock flow. That leads to a race between pfn_valid->memblock_search, and memblock_remove. To fix this, use a read seqlock in memblock_search, which would ensure minimum overhead in search path. And export two APIs to let code doing late memblock remove apply write seqlock. write seqlock would ensure that search retries if the list is updated concurrently. The two exported APIs which should be called before and after modifying memblock regions, late in boot, are - memblock_region_resize_late_begin - memblock_region_resize_late_end The code to alter memblock regions should be guarded by these APIs.
