For the patches applied together with a jailbreak, most groups rely on a list of patches generated by comex. See https://github.com/comex/datautils0/blob/master/make_kernel_patchfile.c

See also saurik's comment for a list of "the 'best practice' patches that jailbreaks install by default" on ycombinator.
