After way to many months here is the fifth version of the guest page hinting patches. Compared to version four a few improvements have been added: - Avoid page_host_discards() calls outside of page-states.h - The discard list is now implemented via the page_free_discarded hook and architecture specific code. - PG_state_change page flag has been replaced with architecture specficic

...'s insane to set file limits for root during boot, the only problem I know of were because of the old userspace that doesn't handle correctly the new ulimited defines ~0UL instead of ~0UL>>1. We can provide total backwards compatibility with a simple IS_BLK check in generic_file_* in filemap.c, but I'm not sure if it really worth to add a branch there just for this.
