mainlining shenanigans
Enable set_migratetype_isolate() to check specified range for unmovable pages during isolation to prepare arbitrary range page isolation. The functionality will take effect in upcoming commits by adjusting the callers of start_isolate_page_range(), which uses set_migratetype_isolate(). For example, alloc_contig_range(), which calls start_isolate_page_range(), accepts unaligned ranges, but because page isolation is currently done at MAX_ORDER_NR_PAEGS granularity, pages that are out of the specified range but withint MAX_ORDER_NR_PAEGS alignment might be attempted for isolation and the failure of isolating these unrelated pages fails the whole operation undesirably.

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
