PS3 fixups for interrups on SMP. Fixes the alignment of the interrupt status bitmap, changes the hypervisor interrupt calls to the '_ext' versions that take an explicit processor thread ID.

Fix two minor bugs in the PS3 system bus mmio region code. First, on error or when freeing a region, retain the bus_addr and len fields to allow subsequent calls to create the region. Second, correct the region address argument to the lv1_unmap_device_mmio_region() call. Fixes modprobe/rmmod of some drivers.

Handle storage-related repository data: - Add missing implementations of ps3_repository_read_stor_*() repository accessors. - Dump storage properties in debug mode - Add PS3_DEV_TYPE_STOR_{DISK,ROM,FLASH} device types (which are identical to the corresponding SCSI device types) to enum ps3_dev_type Signed-off-by: Geert Uytterhoeven <Geert.Uytterhoeven@sonycom.com> Signed-off-by: Geoff Levand <geoffrey.levand@am.sony.com> Acked-by: Arnd Bergmann <arnd.bergmann@de.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>

Various fixes for the PS3 repository code: - Sync signatures of function prototypes and implementations (enum vs. unsigned int) - Correct references to `regions' as `registers': o Correct enum ps3_region_type as enum ps3_reg_type, o Correct PS3_REGION_TYPE_* as PS3_REG_TYPE_*, o Correct ps3_repository_find_region() as ps3_repository_find_reg(). - Correct function name in pr_debug() call - Minor error condition improvements.

It appears that EEH is improperly enabled for some Power4 systems. On these systems, the ibm,set-eeh-option returns a value of success even when EEH is not supported on the given node. Thus, an explicit check for support is required. During boot, on power4, without this patch, one sees messages similar to: EEH: event on unsupported device, rc=0 dn=/pci@400000000110/IBM,sp@1 EEH: event on unsupported device, rc=0 dn=/pci@400000000110/pci@2 EEH: event on unsupported device, rc=0 dn=/pci@400000000110/pci@2,2 etc. The patch makes these go away. Without this patch, EEH recovery does seem to work correctly for at least some devices (I tested ethernet e1000), but fails to recover others (the Emulex LightPulse LPFC, most notably). Off the top of my head, I don't remember why some devices are affected, but not others. The PAPR indicates that the correct way to test for EEH is as done in this patch; its not clear to me if this was in the PAPR all along, or recently added; if it was there all along, its not clear to me why this hadn't been fixed long ago. I suspect only certain firmware levels are affected. Signed-off-by: Linas Vepstas <linas@austin.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>

Including support for non-coherent cache, some mm-related things + relevant field in Kconfig and Makefiles. Also included rheap.o compilation if 8xx is defined. Non-coherent mapping were refined and renamed according to Cristoph Hellwig. Orphaned functions were cleaned up. [Also removed arch/ppc/kernel/dma-mapping.c, because otherwise compiling with ARCH=ppc for a non DMA-cache-coherent platform ends up with two copies of __dma_alloc_coherent etc. -- paulus.] Signed-off-by: Vitaly Bordug <vbordug@ru.mvista.com> Signed-off-by: Paul Mackerras <paulus@samba.org>

This is just a straight port of the same done in arch/ppc by Marcelo Tosatti.

This makes cpm uart able to work using OF-passed parameters in case of CPM stuff (found on most mpc8xx reference and custom boards).

It's useful to have access to struct ipic handle that just got created in ipic_init(). For example, if we want to setup an external IRQ with out a device node we need access ipic->irqhost to create the virtual to HW IRQ mapping and to set the IRQ sense. With this we can mimic the old sense array concept that existed in arch/ppc. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

It's possibly that we get an reset requestion when interrupts are disabled. (For example an oops in an interrupt handler). Therefor, we can't call ioremap in the reset function. Moving the ioremap of the registers we need access to an arch_initcall helps the problem. However we still have a window between boot and the arch_initcall in which the register pointer will not be setup and thus we spin if the reset function is called. If one needs to ensure even this case is covered, look at use of the watchdog provided on 83xx to reset the processor. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
