Use separate data for SoC dependent parameters. These parameters depends on the DMA integration (either in HW or in SYSFW), the DMA controller itself remains compatible with either the am654 or j721e variant. j7200 have the same DMA as j721e with different number of channels, which can be queried from HW, but SYSFW defines different rchan_oes_offset number for j7200 (0x80) compared to j721e (0x400).

2020-09-05io_uring: fix cancel of deferred reqs with ->filesPavel Begunkov
While trying to cancel requests with ->files, it also should look for requests in ->defer_list, otherwise it might end up hanging a thread. Cancel all requests in ->defer_list up to the last request there with matching ->files, that's needed to follow drain ordering semantics.

2020-09-05mm/khugepaged.c: fix khugepaged's request size in collapse_fileDavid Howells
collapse_file() in khugepaged passes PAGE_SIZE as the number of pages to be read to page_cache_sync_readahead(). The intent was probably to read a single page. Fix it to use the number of pages to the end of the window instead.
