[Patch 0/2] Kexec/Kdump support POWER6

[Sachin P. Sant]

Here is updated set of patches which adds kdump support for Power6.

The first patch reads VRMA page size from device tree.

Second patch adds Kexec/Kdump support for Power6 processor. 
On Power machines supporting VRMA, Kexec/Kdump does not work.
Hypervisor stores VRMA mapping used by the OS, in the hpte 
hash tables. This patch makes sure these hpte entries are 
left untouched.

Thanks
