      [PATCH] core remove PageReserved · b5810039
      Nick Piggin 提交于
      Remove PageReserved() calls from core code by tightening VM_RESERVED
      handling in mm/ to cover PageReserved functionality.
      
      PageReserved special casing is removed from get_page and put_page.
      
      All setting and clearing of PageReserved is retained, and it is now flagged
      in the page_alloc checks to help ensure we don't introduce any refcount
      based freeing of Reserved pages.
      
      MAP_PRIVATE, PROT_WRITE of VM_RESERVED regions is tentatively being
      deprecated.  We never completely handled it correctly anyway, and is be
      reintroduced in future if required (Hugh has a proof of concept).
      
      Once PageReserved() calls are removed from kernel/power/swsusp.c, and all
      arch/ and driver code, the Set and Clear calls, and the PG_reserved bit can
      be trivially removed.
      
      Last real user of PageReserved is swsusp, which uses PageReserved to
      determine whether a struct page points to valid memory or not.  This still
      needs to be addressed (a generic page_is_ram() should work).
      
      A last caveat: the ZERO_PAGE is now refcounted and managed with rmap (and
      thus mapcounted and count towards shared rss).  These writes to the struct
      page could cause excessive cacheline bouncing on big systems.  There are a
      number of ways this could be addressed if it is an issue.

      Initial git repository build. I'm not bothering with the full history,
      even though we have it. We can create a separate "historical" git
      archive of that later if we want to, and in the meantime it's about
      3.2GB when imported into git - space that would just make the early
      git days unnecessarily complicated, when we don't have a lot of good
      infrastructure for it.
      
      Let it rip!
