      [ARM PATCH] 1255/1: [PATCH] SA-1111 PCI support for USB · 969d67a8
      Christopher Hoover authored
      Fixes several oopsen in the SA-1111 "fake" PCI support
      
      Complete re-write of the SA-1111 DMA bug "bounce buffer" workaround.
      
      Merge latest drivers/pci/pool.c into mach-sa1100/pcipool.c (pool
      allocation debugging follows CONFIG_DEBUG_SLAB a la drivers/pci/pool.c)
      
      /arch/arm/mach-sa1100/pcipool.h can be deleted
      (unrelated: /arch/arm/mach-sa1100/sa1111-ohci.c can be deleted)
      
      Applies to 2.5.30-rmk1.  Should be back ported to 2.4 as the existing
      SA-1111 bounce buffer code is broken.
      
      (This patch is *required* for the OHCI HCD driver that is part of 2.5.21+.)

      [ARM] Fix XScale "feature" · 01561776
      Russell King authored
      XScale does not guarantee that CPU control register writes complete
      their side effects immediately.  In fact, Intel give sample code to
      demonstrate a way to ensure that the effect of the write has occurred.
      This is specific to Xscale, but the fix should work on any ARM CPU.
      We therefore jump through the loops in "spirit" but not necessarily
      in exactly the same way as the sample code.

      [ARM] Make "bootp" Image generation know that the zImage is now PIC. · 5e2076c4
      Russell King authored
      Since a bootp image contains a zImage and an initrd (or maybe later
      an initramfs) image, and the zImage is now PIC, we don't have to
      copy the zImage to a specific address before calling it.  We just
      call it where it got loaded into memory and let it sort itself out.

      [ARM] Always decend into compressed and bootp subdirectories. · 3e6157d0
      Russell King authored
      Make was missing the need to rebuild the kernel decompressor when
      files in arch/arm/boot/compressed are changed.  This is because
      make believes that the object contained within is up to date
      (because it doesn't know any better.)  This cset always forces us
      to decend into these two directories if the objects inside these
      are required.

      [ARM] Thumb fixes · d905f752
      Russell King authored
      This cset fixes a set of problems discovered while developing KLIBC
      with Thumb support.  We now allow pure Thumb executables, and prevent
      such executables from being run on non-Thumb code aware CPUs.
      We also fix a bug in the fixup of Thumb late aborts which rather
      messed things up.

      [ARM] Add Thumb syscall stubs and drop gcc asm workarounds. · 04e1aae5
      Russell King authored
      Add support for Thumb stubs (for klibc.)
      We drop a work-around for early gcc versions where register
      variables didn't work as expected; this allows us to get rid
      of several lines of ASM per syscall.

      [PATCH] Improve READDIR/READDIRPLUS sanity checking.. · 29ceefc7
      Trond Myklebust authored
       - Use req->rq_received to determine the message length instead of
         assuming that it goes to the end of the page.
      
       - If the server returned an illegal record so that we cannot make
         progress by retrying the request on a fresh page, truncate the
         entire listing and return a syslog error.

      [PATCH] Improve NFS READ reply sanity checking · d9a4ea27
      Trond Myklebust authored
       - Fix the check for whether or not the received message length has
         somehow been truncated: we need to use req->rq_received rather
         than the receive buffer length (req->rq_rlen).
      
       - Ensure that we set res->eof correctly. In particular, we need to
         clear it if we find ourselves attempting to recover from a
         truncated READ.
      
       - Don't set PageUptodate() on those pages that are the victim of
         message truncation.

      [PATCH] spinlock.h cleanup · e4039bb2
      Robert Love authored
       - cleanup #defines: I do not follow the rationale behind the
         odd line-wrapped defines at the beginning of the file.  If
         we have to use multiple lines, then we might as well do so
         cleanly and according to normal practice...
      
       - Remove a level of indirection: do not have spin_lock_foo
         use spin_lock - just explicitly call what is needed.
      
       - we do not need to define the spin_lock functions twice, once
         for CONFIG_PREEMPT and once for !CONFIG_PREEMPT.  Defining
         them once with the preempt macros will optimize away fine.
      
       - cleanup preempt.h too
      
       - other misc. cleanup, improved comments, reordering, etc.

      [PATCH] O(1) sys_exit(), threading, scalable-exit-2.5.31-A6 · 1edfa642
      Ingo Molnar authored
      This fixes the ptrace wait4() anomaly that can be observed in any
      previous Linux kernel i could get my hands at.
      
      If the parent still has other children (that are being traced by
      somebody), we wait for them or return immediately without an error in
      case of WNOHANG.

      [PATCH] Fix a BUG in try_to_unmap() · 0ee29e60
      Andrew Morton authored
      try_to_unmap() dies if the to-be-unmapped page has a non-NULL ->mapping.
      
      But the preceding logic in shrink_cache() forgot about the
      rarely-occurring pages which have buffers and no ->mapping.

      [PATCH] fix uniprocessor lockups · 891975a1
      Andrew Morton authored
      I have a test_and_set_bit(PG_chainlock, page->flags) in page reclaim.
      Which works fine on SMP.  But on uniprocessor, we made
      pte_chain_unlock() a no-op, so all pages end up with PG_chainlock set.
      refill_inactive() cannot move any pages onto the inactive list and the
      machine dies.
      
      The patch removes the test_and_set_bit optimisation in there and just
      uses pte_chain_lock().  If we want that (dubious) optimisation back
      then let's do it right and create pte_chain_trylock().

      [PATCH] Fix a race between __page_cache_release() and shrink_cache() · 9bdedfce
      Andrew Morton authored
      __page_cache_release() needs to recheck the page count inside the LRU
      lock, because shrink_cache() may have found the page on the LRU and
      incremented its refcount again.
      
      Which is carefully documented over __pagevec_release().  Duh.

      [PATCH] NUMA-Q disable irqbalance · 01a8d063
      Dave Hansen authored
      Here's a patch from Andrea's tree that uses IRQ_BALANCE_INTERVAL to
      define how often interrupts are balanced, staying independent from HZ.
      
        It also makes sure that there _is_ a change to the configuration
      before it actually writes it.  It reminds me of the mod_timer
      optimization.

      [PATCH] O(1) sys_exit(), threading, scalable-exit-2.5.31-B4 · d79c07a4
      Ingo Molnar authored
      the attached patch updates a number of items:
      
       - adds cleanups suggested by Christoph Hellwig: needed unlikely()
         statements, a superfluous #define and line length problems.
      
       - splits up the global ptrace list into per-task ptrace lists. This was
         pretty straightforward, and this makes the worst-case exit() latency
         O(nr_children).
      
      the per-task ptrace lists unearthed a bug that the previous code did not
      take care of: tasks on the ptrace list have to be correctly reparented as
      well. This patch passed my stresstests as well.
