The per-pci-device 'debug' attribute is ill defined. For each device it prints the same information, the adapter interrupt bit vector for irq numbers 0 & 1, the start of the global interrupt summary vector and the global irq retries counter. Just remove the attribute and the associated code. Signed-off-by:Martin Schwidefsky <schwidefsky@de.ibm.com>

The patch decomposes the function test_facility() into its API test_facility() and its implementation __test_facility(). This allows to reuse the implementation with a different API. Patch is used to prepare checkin of SIE satellite code. Signed-off-by:

Copy the interrupt parameters from the lowcore to the pt_regs structure in entry[64].S and reduce the arguments of the low level interrupt handler to the pt_regs pointer only. In addition move the test-pending-interrupt loop from do_IRQ to entry[64].S to make sure that interrupt information is always delivered via pt_regs. Signed-off-by: -

The disable slot implementation on s390 currently just detaches the pci function from the partition - without informing the pci layer. Fix this by calling pci_stop_and_remove_bus_device prior to the operation. Reviewed-by:

Add a kernel parameter to be able to specify the number of pages to be used as output buffer by the line-mode sclp driver and the vt220 sclp driver. The current number of output pages is 6, if the service element is unavailable the boot messages alone can fill up the output buffer. If this happens the system blocks until the service element is working again. For a large LPAR with many devices it is sensible to have the ability to increase the output buffer size. To help to debug this situation add a counter for the page-pool-empty situation and make it available as a sclp driver attribute. To avoid the system to stall until the service element works again add another kernel parameter to allow to drop output buffers. Signed-off-by: -

virt_to_phys on s390 currently uses the LRA instruction to translate virtual to physical addresses. This creates an unnecessary overhead and caused trouble with dma debugging code (when called with an address pointing to a already unmapped page). Just get rid of s390's implementation and use the one from asm-generic/io.h . Note: with this change virt_to_phys will no longer work on vmalloc'ed addresses. Reviewed-by:

Since 9a46ad6d "smp: make smp_call_function_many() use logic similar to smp_call_function_single()" generic_smp_call_function_interrupt() is only an alias to generic_smp_call_function_single_interrupt(). So remove the superfluous variant. Signed-off-by:

The following commit caused a fatal oops when booting on mpc83xx with a non-express PCI bus (regardless of whether a PCI device is present): commit 50d8f87d Author: Rojhalat Ibrahim <imr@rtschenk.de> Date: Mon Apr 8 10:15:28 2013 +0200 powerpc/fsl-pci Make PCIe hotplug work with Freescale PCIe controllers Up to now the PCIe link status on Freescale PCIe controllers was only checked once at boot time. So hotplug did not work. With this patch the link status is checked on every config read. PCIe devices not present at boot time are found after doing 'echo 1 >/sys/bus/pci/rescan'. Signed-off-by:
