Breno Leitao 402e172a2c powerpc/xmon: Check before calling xive functions ... Currently xmon could call XIVE functions from OPAL even if the XIVE is disabled or does not exist in the system, as in POWER8 machines. This causes the following exception: 1:mon> dx cpu 0x1: Vector: 700 (Program Check) at [c000000423c93450] pc: c00000000009cfa4: opal_xive_dump+0x50/0x68 lr: c0000000000997b8: opal_return+0x0/0x50 This patch simply checks if XIVE is enabled before calling XIVE functions.
