There are\nstill some issues to be investigated as, in some occasions, after a\ncouple of plug and unplug, the cpu which was removed receives a 'lost'\ninterrupt. This showed to be the decrementer under QEMU.\n\nNevertheless, these patches are required and provide a significant\nimprovement to support CPU removal.\n\nTested under a phyp and a XIVE QEMU model for pseries.\n\nThanks,\n\nC.\n\nCédric Le Goater (2):\n powerpc/xive: fix IPI reset\n powerpc/xive: fix cpu removal\n\n arch/powerpc/sysdev/xive/common.c | 8 ++++++++\n arch/powerpc/sysdev/xive/spapr.c | 4 ++++\n 2 files changed, 12 insertions(+)"}
