smp_send_stop() will send an IPI to all other cpus to shut them down. However, for the case of xmon-based reboots (as well as potentially some panics), the other cpus are (or might be) spinning with interrupts off, and won't take the IPI. Current code will drop us into the debugger when the IPI fails, which means we're in an infinite loop that we can't get out of without an external reset of some sort. Instead, make the smp_send_stop() IPI call path just print the warning about being unable to send IPIs, but make it return so the rest of the shutdown sequence can continue. It's not perfect, but the lesser of two evils. Also move the call_lock handling outside of smp_call_function_map so we can avoid deadlocks in smp_send_stop(). Signed-off-by:

The e500 MMU init code previously assumed KERNELBASE always equaled PAGE_OFFSET and PHYSICAL_START was 0. This is useful for kdump support as well as asymetric multicore. For the initial kdump support the secondary kernel will run at 32M but need access to all of memory so we bump the initial TLB up to 64M. This also matches with the forth coming ePAPR spec.

The current PCI code for Freescale 85xx/86xx was treating the virtual P2P PCIe bridge as a transparent bridge. Rather than doing that fixup the virtual P2P bridge by copying the resources from the PHB. Also, fixup a bit of the code for dealing with resource_size_t being 64-bits and how we set ATMU registers for >4G. Signed-off-by: -
