      MIPS: N32: Fix preadv(2) and pwritev(2) entry points. · d5563715
      Ralf Baechle authored
      By using the native syscall entry point the kernel was also expecting
      64-bit iovec structures.
      
      This is broken since ddd9e91b [preadv/
      pwritev: MIPS: Add preadv(2) and pwritev(2) syscalls.] which originally
      added these two syscalls.  I walked through piles of code, including
      libc and couldn't find anything that would have worked around the issue
      so this change the API to what it should always have been.
      
      Noticed and patch suggested by Al Viro.

      MIPS: Avoid mcheck by flushing page range in huge_ptep_set_access_flags() · ac53c4fc
      David Daney authored
      Problem:
      
      1) Huge page mapping of anonymous memory is initially invalid.  Will be
         faulted in by copy-on-write mechanism.
      
      2) Userspace attempts store at the end of the huge mapping.
      
      3) TLB Refill exception handler fill TLB with a normal (4K sized)
         invalid page at the end of the huge mapping virtual address range.
      
      4) Userspace restarted, and re-attempts the store at the end of the
         huge mapping.
      
      5) Page from #3 is invalid, we get a fault and go to the hugepage
         fault handler.  This tries to map a huge page and calls
         huge_ptep_set_access_flags() to install the mapping.
      
      6) We just call the generic ptep_set_access_flags() to set up the page
         tables, but the flush there assumes a normal (4K sized) page and
         only tries to flush the first part of the huge page virtual address
         out of the TLB, since the existing entry from step #3 doesn't
         conflict, nothing is flushed.
      
      7) We attempt to load the mapping into the TLB, but because it
         conflicts with the entry from step #3, we get a Machine Check
         exception.
      
      The fix: Flush the entire rage covered by the huge page in
      huge_ptep_set_access_flags(), and remove the optimization in
      local_flush_tlb_range() so that the flush actually does the correct
      thing.

      Pull MTD fixes from David Woodhouse:
       "The most important part of this is that it fixes a regression in
        Samsung NAND chip detection, introduced by some rework which went into
        3.7.  The initial fix wasn't quite complete, so it's in two parts.  In
        fact the first part is committed twice (Artem committed his own copy
        of the same patch) and I've merged Artem's tree into mine which
        already had that fix.
      
        I'd have recommitted that to make it somewhat cleaner, but figured by
        this point in the release cycle it was better to merge *exactly* the
        commits which have been in linux-next.
      
        If I'd recommitted, I'd also omit the sparse warning fix.  But it's
        there, and it's harmless — just marking one function as 'static' in
        onenand code.
      
        This also includes a couple more fixes for stable: an AB-BA deadlock
        in JFFS2, and an invalid range check in slram."
