Yes. I will revert these two patches in Linux 3.9 kernel. However, I'm
waiting to merge these two patches into the stable kernel (v3.8.3),
because following patch needs these two patches.

  [PATCH v2] sp5100_tco: Remove code that may cause a boot failure
  https://lkml.org/lkml/2013/3/3/6

Currently, the code of sp5100_tco driver differs between Linux 3.9
kernel and stable kernel, because the following patches aren't applied
to stable kernel.

  [PATCH 1/2] sp5100_tco: Fix wrong indirect I/O access for getting
value of reserved
 https://lkml.org/lkml/2013/1/13/176
  [PATCH 2/2] sp5100_tco: Write back the original value to reserved
bits, instead of zero
 http://lkml.org/lkml/2013/1/13/173

When these two patches are applied to stable kernel, the code of
sp5100_tco in stable kernel is the same as Linux 3.9 kernel. Since the
patch ('Remove code that may cause a boot failure') was written based
on Linux 3.9, the patch can fix both Linux 3.9 kernel and stable
kernel.

>> queue-3.8/watchdog-sp5100_tco-write-back-the-original-value-to-reserved-bits-instead-of-zero.patch

After these two patches were merged into the stable kernel, I'm going
to post the "Remove code that may cause a boot failure" patch which
has improved the commit log to stable@xxxxxxxxxxxxxxx.
