Its usually possible to spot the pattern from "git log --oneline $file".

I can't parse this. create_safe_exec_page() uses hibernate's allocator to create a set of page table to map a single page that will contain the relocation code. > Remove the allocator related arguments, and use get_safe_page > directly, as it is done in other local functions in this > file. ... because kexec can't use this as it doesn't have a working allocator. Removing this function pointer makes it easier to refactor the code later. (this thing is only a function pointer so kexec could use it too ... It looks like you're creating extra work. Patch 7 moves these new calls out to a new file... presumably so another patch can remove them again) As stand-alone cleanup the patch looks fine, but you probably don't need to do this.
