[GIT PULL 0/6] TrimSlice backports for linux-tegra-2.6.36

[GIT PULL 0/6] TrimSlice backports for linux-tegra-2.6.36

[Mike Rapoport]

Hi Colin,

Please consider pulling TrimSlice patches backported to
linux-tegra-2.6.36.

The first patch in the series allows ioremapping of PCI space when
CONFIG_PCI=y.
The rest is the TrimSlice patches merged into the mainline, some of
them were squashed into single commit to reduce the noise.

The following changes since commit d3c9f78e7ec505076ddad2aefaeef5e8c20a4823:

  serial: tegra_hsuart: Make sure current byte rx complete in suspend (2011-03-22 11:40:08 -0700)

are available in the git repository at:
  git://git.kernel.org/pub/scm/linux/kernel/git/rppt/linux-tegra.git trimslice/linux-tegra-2.6.36
