| | | | | | | | | | | | | early serial init also utilizes the peripheral request api - however at this point bfin_gpio_init didn't allocate memory for the labels.

* [Blackfin] arch: fix bug - trap_tests fails to recover on some tests.Robin Getz2008-01-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | http://blackfin.uclinux.org/gf/project/uclinux-dist/tracker/?action=TrackerItemEdit&tracker_item_id=3719 When the CPLBs get a miss, we do: - find a victim in the HW table - remove the victim - find the replacement in the software table - put it into the HW table. If we can't find a replacement in the software table, we accidently leave a duplicate in the HW table. This patch ensures that duplicate is marked as not valid. What we should do is find the replacement in the software table, before we find a victim in the HW table - but its too late in the release cycle to do that much restructuring of this code. Rather that duplicate code, connect Hardware Errors (irq5) into trap_c, so user space processes get killed properly. The rest of irq_panic() can be moved into traps.c (later) There is still a small corner case that causes problems when a pheriperal interrupt goes off a single cycle before a user space hardware error. This causes a kernel panic, rather than the user space process being killed. But, this checkin makes things work in 99.9% of the cases, and is a vast improvement from what is there today (which fails 100% of the time).

* [S390] do local_irq_restore while spinning in spin_lock_irqsave.Hisashi Hifumi2008-01-26
| | | | | | | | | | | | | | | | | In s390's spin_lock_irqsave, interrupts remain disabled while spinning. In other architectures like x86 and powerpc, interrupts are re-enabled while spinning if IRQ is not masked before spin_lock_irqsave is called. The following patch re-enables interrupts through local_irq_restore while spinning for a lock acquisition. This can improve system response.

* [S390] Use diag308 subcodes 3 and 6 for reboot and dump when possible.Michael Holzheu2008-01-26
| | | | | | | | | | | | | | | | This patch fixes a problem with the following scenario: 1. Linux booted from DASD "A" 2. Reboot from DASD "B" using "/sys/firmware/reipl/ccw/device" 3. Reboot DASD "B" Without this patch in step 3 on newer s390 systems under LPAR instead of DASD "B", DASD "A" will be booted. The reason is that in step 2 we use CCW reipl and in step 3 we use DIAG308 (subcode 3) reipl. DIAG308 does not notice the CCW reipl and still thinks that it has to reboot DASD "A". Before applying this fix, ensure to have MCF RJ9967101E or z9 GA3 base driver installed. Signed-off-by: Michael Holzheu <holzheu@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
* [S390] vmemmap: allocate struct pages before 1:1 mappingChristian Borntraeger2008-01-26
| | | | | | | | | | | | | | | | We have seen an oops in an OOM situation, where show_mem tried to access the struct page of a dcss segment. The vmemmap code has already created the 1:1 mapping but failed allocating the struct pages. In the OOM case, show_mem now walks the memory. It uses pfn_valid to detect if it may access the struct page. In the case described above, the mapping was established and pfn_valid returned true. As the struct pages were not allocated, the kernel oopsed. We have to ensure that we have created the struct pages, before we add a mapping pointing to the pages.

* [S390] kernel: Shutdown Actions InterfaceMichael Holzheu2008-01-26
| | | | | | | | | | | | | | | | In case of a kernel panic it is currently possible to specify that a dump should be created, the system should be rebooted or stopped. Virtual sysfs files under the directory /sys/firmware/ are used for that configuration. In addition to that, there are kernel parameters 'vmhalt', 'vmpoff' and 'vmpanic', which can be used to specify z/VM commands, which are automatically executed in case of halt, power off or a kernel panic. This patch combines both functionalities and allows to specify the z/VM CP commands also via sysfs attributes. In addition to that, it enhances the existing handling of shutdown triggers (e.g. halt or panic) and associated shutdown actions (e.g. dump or reipl) and makes it more flexible.
