pnv_pci_table_alloc() ignores possible failure from kzalloc_node(),
this adds a check. There are 2 callers of pnv_pci_table_alloc(),
one already checks for tbl!=NULL, this adds WARN_ON() to the other path

Yes you can. But there are some restrictions.
You can only build a 64-bit OR a 32-bit kernel.
And within 64-bit you can only build a *

Hi,
Ok, now we have a new locking issue with interrupts which I found on my P8 box.
I haven't found where we take the console_lock, only in hvc_remove.
BTW, Ben, looks like it's a bug in hvc_remove:
we take spin_lock and then semaphore lock.
