[PATCH 4/4] powerpc: Move boot_paca into early_setup

[Geoff Levand]

The powerpc boot_paca symbol is now only used within the
early_setup() routine, so move it from its global definition
into early_setup().

[PATCH 1/4] powerpc/ps3: Add macro PS3_VERBOSE_RESULT

[Geoff Levand]

To allow more control of the verbosity of ps3_result() add a check
for the preprocessor macro PS3_VERBOSE_RESULT that builds a verbose
verion of the ps3_result() routine.

[PATCH for 3.9] powerpc/ps3: Update ps3_defconfig

[Geoff Levand]

Refresh and set CONFIG_RD_LZMA=y.

Signed-off-by: Geoff Levand <geoff@infradead.org>

Hi Ben,

This sets CONFIG_RD_LZMA=y, which is needed to boot with
newer initrd images.

Please apply for 3.9.

Hi Ben,

It would be nice if I could get this in for 3.9.  Did you miss it?

Thanks.
