Just like Simba bridges, some PCI bridges can lack the 'ranges' OBP property. So we handle this similarly to the existing Simba code: 1) In of_device register address resolving, we push the translation to the parent. 2) In PCI device scanning, we interrogate the PCI config space registers of the PCI bus device in order to resolve the resources, just like the generic Linux PCI probing code does.

* | fix sysrq-m oopsBob Picco2007-06-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We aren't sampling for holes in memory. Thus we encounter a section hole with empty section map pointer for SPARSEMEM and OOPs for show_mem. This issue has been seen in 2.6.21, current git and current mm. The patch below is for mainline and mm. It was boot tested for SPARSEMEM, current VMEMMAP of Andy's in mm ml and DISCONTIGMEM. A slightly different patch will be posted to stable for 2.6.21. Previous to commit f0a5a58aa812b31fd9f197c4ba48245942364eae memory_present was called for node_start_pfn to node_end_pfn. This would cover the hole(s) with reserved pages and valid sections. Most SPARSEMEM supported arches do a pfn_valid check in show_mem before computing the page structure address. This issue was brought to my attention on IRC by Arnaldo Carvalho de Melo. Thanks to Arnaldo for testing.

| | | | | | | | | | | | | | | | | | | | | | The non-rt signal handling was never really used, so we don't break anything.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We used to access the 64-bit IRQ IMAP and ICLR registers of bus controllers 4-bytes in and as a 32-bit register word, since only the low 32-bits were relevant. This seemed like a good idea at the time. But the PCI-E controller requires full 8-byte 64-bit access to these registers, so we switched over to accessing them fully. SBUS was not adjusted properly, which broke interrupts completely. Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a minor fix, but what is currently there is essentially wrong. In do_page_fault, if the faulting address from user code happens to be in kernel address space (int *p = (int*)-1; p = 0xbed;) then the do_page_fault handler will jump over the local_irq_enable with the goto bad_area_nosemaphore; But the first line there sees this is user code and goes through the process of sending a signal to send SIGSEGV to the user task. This whole time interrupts are disabled and the task can not be preempted by a higher priority task. This patch always enables interrupts in the user path of the bad_area_nosemaphore.
