From 654f596da4a83a8d2734fba26c2a1257533e6d75 Mon Sep 17 00:00:00 2001 From: Manish Ahuja Date: Sat, 22 Mar 2008 11:38:59 +1100 Subject: [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.
