One of the easiest things to isolate is the pid printed in kernel log. There was a patch, that made this for arch-independent code, this one makes so for arch/xxx files. It took some time to cross-compile it, but hopefully these are all the printks in arch code.

This is the largest patch in the set. Make all (I hope) the places where the pid is shown to or get from user operate on the virtual pids. The idea is: - all in-kernel data structures must store either struct pid itself or the pid's global nr, obtained with pid_nr() call; - when seeking the task from kernel code with the stored id one should use find_task_by_pid() call that works with global pids; - when showing pid's numerical value to the user the virtual one should be used, but however when one shows task's pid outside this task's namespace the global one is to be used; - when getting the pid from userspace one need to consider this as the virtual one and use appropriate task/pid-searching functions.

For some time /proc/sys/kernel/core_pattern has been able to set its output destination as a pipe, allowing a user space helper to receive and intellegently process a core. This infrastructure however has some shortcommings which can be enhanced. Specifically: 1) The coredump code in the kernel should ignore RLIMIT_CORE limitation when core_pattern is a pipe, since file system resources are not being consumed in this case, unless the user application wishes to save the core, at which point the app is restricted by usual file system limits and restrictions. 2) The core_pattern code should be able to parse and pass options to the user space helper as an argv array. The real core limit of the uid of the crashing proces should also be passable to the user space helper (since it is overridden to zero when called). 3) Some miscellaneous bugs need to be cleaned up (specifically the recognition of a recursive core dump, should the user mode helper itself crash. Also, the core dump code in the kernel should not wait for the user mode helper to exit, since the same context is responsible for writing to the pipe, and a read of the pipe by the user mode helper will result in a deadlock. This patch: Remove the check of RLIMIT_CORE if core_pattern is a pipe. In the event that core_pattern is a pipe, the entire core will be fed to the user mode helper.

We were simply concatenating the devhandle and devino and using that as the cookie, which defeats the entire purpose of the VIRQ hypervisor interfaces. Now that we use physical addresses for the INO buckets, we can allocate them dynamically for VIRQs and encode the cookies as ~__pa(bucket). This allows us to test for and decode the cookie with a simple: brlz $reg1, 1f xnor $reg1, %g0, $reg2 sequence. This works because bit 64 is never set in traditional INO vectors, and it is also never set in a physical address. So xnor'ing the physical address of the bucket always gives us a negative number, and thus a unique condition we can test cheaply. Inspired by ideas from Greg Onufer. Signed-off-by: NDavid S.

Currently we chain IVEC entries using 32-bit "pointers" because we know that the ivector_table is in the main kernel image, thus below 4GB. This uses proper 64-bit pointers instead. Whilst this bloats up the kernel image size, this sets the infrastructure necessary to significantly shrink the kernel size by using physical addresses and dynamically allocating the ivector table.

This also makes us use the MSI queues correctly. Each MSI queue is serviced by a normal sun4u/sun4v INO interrupt handler. This handler runs the MSI queue and dispatches the virtual interrupts indicated by arriving MSIs in that MSI queue. All of the common logic is placed in pci_msi.c, with callbacks to handle the PCI controller specific aspects of the operations. This common infrastructure will make it much easier to add MSG support.

Thanks to Tom Callaway for the excellent bug report and test case. sys_ipc() has several problems, most to due with semaphore call handling: 1) 'err' return should be a 'long' 2) "union semun" is passed in a register on 64-bit compared to 32-bit which provides it on the stack and therefore by reference 3) Second and third arguments to SEMCTL are swapped compared to 32-bit.

The PCI-E slot on T1000 connects directly to the Fire PCI chip with no intervening bridges visible in the OBP tree. Unfortunately the bus numbering of the device in that slot is different (2) from the PCI host controller (0), and thus the pci_bus_{read,write}_config_*() calls don't work out. Complicating things further the Fire PCI controller has no config space it responds to either. For now treat this case specially so that devices in the slot work. Longer term we need to perhaps cons up a dummy bridge between the Fire and the PCI-E slot so that the bus hierarchy is complete inside of the kernel and thus the bus numbering all works out right.
