Hi Tony-san, and kdump folks,
I got some trouble on kdump on IPF with INIT, and my investigation
proves there are some bugs and races in startup of kdump.
Here are fixes based on .30, for issues I found.
Since it must be serious problem for (likely big) IPF servers if we
could fail to retrieve crashdump via kdump, so I believe these patches
should be applied asap.
Hidetoshi Seto (7):
ia64, kdump: Mask MCA/INIT on freezing cpus
ia64, kexec: Make INIT safe while kdump/kexec
ia64, kexec: Unregister MCA handler before kexec
ia64, kdump: Don't offline APs
ia64, kdump: Mask INIT first in panic-kdump path
ia64, kdump: Try INIT regardless of kdump_on_init
ia64, kdump: Short path to freeze CPUs
