  Resend lost APIC IRQs on Uniprocessor too
  
  From: Petr Vandrovec
  
  hw_resend_irq must be enabled on uni processor IO_APIC kernel too. This will
  prevent some lost interrupts (e.g. together with VIA IDE hardware)

  Fix reference counting bug in change_page_attr on i386/x86-64
  
  When not splitting a page the reference count must be increased too.
  Found by several people in 2.6, one of them was Andrea Arcangelli, other
  names I don't remember (sorry).

  [PATCH] x86_64: Backport 2.6 MTRR algorithms
  
  Backport 2.6 MTRR algorithms
  
  Don't assume 40bits of address space anymore .
  This avoids various problems on Xeons which currently have only 36bits.
  
  We use the tested code from 2.6 as replacement, so this should
  be fairly safe.
  
  Thanks to Philip Pokorny for a lot of investigation on this issue.
  I ended up redoing his patch so all blame to me.

  [PATCH] x86_64: Handle MM going away in context switch.
  
  Handle MM going away in context switch.
  
  Fix a long standing bug lazy TLB handling on x86-64. When
  switching to a lazy TLB thread we must handle the race of the
  mm currently going away. If that's the case always load the
  page tables of the next process. This way we avoid having
  freed page tables in a CPU's TLB, which can lead to machine
  checks in some situations on Opteron.
  
  Credit goes to some anonymous AMD debugging wizards who tracked down
  the problem. I did the fix. All blame to me.

  [PATCH] madvise_willneed -EIO beyond EOF
  
  When the rlim_rss was removed from madvise_willneed, we unintentionally
  changed its error when applied to an area wholly beyond end of file: it
  used to report -EIO (whereas 2.6 reports success), it currently reports
  the confusingly inappropriate -EBADF.  Revert to -EIO in that case.

  Daniel, thank you for the patch, it seems fine. I have it in RHEL 3 U5.
  I didn't post it before because I thought nobody cared about enhancements
  to 2.4 anymore except enterprise users with legacy hardware. Knowing
  Marcelo though, I expect this to be bumped to 2.4.31.

  #   [PATCH] rwsem: Make rwsems use interrupt disabling spinlocks
  #
  #   The attached patch makes read/write semaphores use interrupt disabling
  #   spinlocks in the slow path, thus rendering the up functions and trylock
  #   functions available for use in interrupt context.  This matches the
  #   regular semaphore behaviour.
  #
  #   I've assumed that the normal down functions must be called with interrupts
  #   enabled (since they might schedule), and used the irq-disabling spinlock
  #   variants that don't save the flags.
