[PATCH] ppc64: bugfix: crash on PCI hotplug
09-hotplug-bugfix.patch
In the current 2.6.14-rc2-git6 kernel, performing a Dynamic LPAR Add
of a hotplug slot will crash the system, with the following (abbreviated)
stack trace:
cpu 0x3: Vector: 700 (Program Check) at [c000000053dff7f0]
pc: c0000000004f5974: .__alloc_bootmem+0x0/0xb0
lr: c0000000000258a0: .update_dn_pci_info+0x108/0x118
c0000000000257c8 .update_dn_pci_info+0x30/0x118 (unreliable)
c0000000000258fc .pci_dn_reconfig_notifier+0x4c/0x64
c000000000060754 .notifier_call_chain+0x68/0x9c
The root cause was that __init __alloc_bootmem() was called long after
boot had finished, resulting in a crash because this routine is undefined
after boot time. The patch below fixes this crash, and adds some docs to
clarify the code.
