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: NMartin Schwidefsky <schwidefsky@de.ibm.com>

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.

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: NRojhalat Ibrahim <imr@rtschenk.de> Signed-off-by: NKumar Gala <galak@kernel.crashing.org> This patch fixes the issue by calling setup_indirect_pci for all device types. fsl_indirect_read_config is now only used for booke/86xx PCIe controllers.
