9b48b46678 [IA64-SGI] move nodepda pointer out of pda
Remove the p_nodepda and p_subnodepda pointers from the pda_s structure.
And then define a new per-cpu pointer to the nodepda and export it so

de7548d0e2 [IA64-SGI] Altix only: Fix for sn_dma_flush
The following patch fixes a bug in the SGI Altix sn_dma_flush code.  
sn_dma_flush is broken in 2.6.  The code isn't waiting for the DMA 
data to be flushed out of the PIC ASIC. This patch is based off the 
linux-ia64-test-2.6.12 tree

This patch against ia64-test-2.6.12 is needed for forthcoming
Altix chipsets. It renames geoid_any_t to geoid_common_t and
splits the 8bit 'slab' field into two 4bit fields for 'slab'
and 'slot'. Similar changes in the Altix SAL will retain backward
compatibility for old kernels.

c1298c5c7e [IA64-SGI] Altix: enable poweroff
This patch adds the necessary "hook" to allow SGI/SN
machines to perform a system power off upon a 
'init 0', 'halt -p', 'poweroff' or 'shutdown -h'.

The "hook" is to set the pm_power_off callback
to ia64_sn_power_down(). pm_power_off is checked
in machine_power_off()/do_poweroff() and, if set, is executed. 
ia64_sn_power_down() is a function already present (but not 
used currently) in the sn kernel.
ia64_sn_power_down() makes a SAL call to execute the
power off.

1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
