Manish Ahuja	654f596da4	[POWERPC] pseries: phyp dump: Disable phyp-dump through boot-var ... This adds a kernel command line option "phyp_dump", which takes a 0/1 value for disabling/ enabling phyp_dump at boot time. Kdump can use this on cmdline (phyp_dump=0) to disable phyp-dump during boot when enabling itself. This will ensure only one dumping mechanism is active at any given time.

Manish Ahuja	6ac26c8a7e	[POWERPC] pseries: phyp dump: Reserve and release memory ... Initial patch for reserving memory in early boot, and freeing it later. If the previous boot had ended with a crash, the reserved memory would contain a copy of the crashed kernel data.
