      pccard_store_cis: fix wrong error handling · d834c165
      Linus Torvalds authored
      
      
      The test for the error from pcmcia_replace_cis() was incorrect, and
      would always trigger (because if an error didn't happen, the "ret" value
      would not be zero, it would be the passed-in count).
      
      Reported and debugged by Fabrice Bellet <fabrice@bellet.info>
      
      Rather than just fix the single broken test, make the code in question
      use an understandable code-sequence instead, fixing the whole function
      to be more readable.

      [PATCH] Some config.h removals · 5a73fdc5
      Zachary Amsden authored
      
      
      During tracking down a PAE compile failure, I found that config.h was being
      included in a bunch of places in i386 code.  It is no longer necessary, so
      drop it.

      [PATCH] paravirt: update pte hook · 789e6ac0
      Zachary Amsden authored
      
      
      Add a pte_update_hook which notifies about pte changes that have been made
      without using the set_pte / clear_pte interfaces.  This allows shadow mode
      hypervisors which do not trap on page table access to maintain synchronized
      shadows.
      
      It also turns out, there was one pte update in PAE mode that wasn't using any
      accessor interface at all for setting NX protection.  Considering it is PAE
      specific, and the accessor is i386 specific, I didn't want to add a generic
      encapsulation of this behavior yet.

      [PATCH] paravirt: remove set pte atomic · a93cb055
      Zachary Amsden authored
      
      
      Now that ptep_establish has a definition in PAE i386 3-level paging code, the
      only paging model which is insane enough to have multi-word hardware PTEs
      which are not efficient to set atomically, we can remove the ghost of
      set_pte_atomic from other architectures which falesly duplicated it, and
      remove all knowledge of it from the generic pgtable code.
      
      set_pte_atomic is now a private pte operator which is specific to i386

      [PATCH] paravirt: optimize ptep establish for pae · d6d861e3
      Zachary Amsden authored
      
      
      The ptep_establish macro is only used on user-level PTEs, for P->P mapping
      changes.  Since these always happen under protection of the pagetable lock,
      the strong synchronization of a 64-bit cmpxchg is not needed, in fact, not
      even a lock prefix needs to be used.  We can simply instead clear the P-bit,
      followed by a normal set.  The write ordering is still important to avoid the
      possibility of the TLB snooping a partially written PTE and getting a bad
      mapping installed.
