Currently we hardwire the number of SLBs to 64, but PAPR says we should use the ibm,slb-size property to obtain the number of SLB entries. This uses this property instead of assuming 64. If no property is found, we assume 64 entries as before. This soft patches the SLB handler, so it shouldn't change performance at all. Signed-off-by:

It only needs the iommu_table address. It also makes use of the node name to print error messages. So just pass it the things it needs. This reduces the places that know about the pci_dn by one. Signed-off-by:

The 'data' member of proc_ppc64_lparcfg is unused, but the lparcfg module's init routine allocates 4K for it. Remove the code which allocates and frees this buffer. Signed-off-by:

* 'upstream-linus' of master.kernel.org:/pub/scm/linux/kernel/git/jgarzik/libata-dev: libata: kill spurious NCQ completion detection ahci: don't attach if ICH6 is in combined mode ata_piix: add Toshiba Tecra M4 to broken suspend list ahci: fix engine reset failed message
-

Spurious NCQ completion detection implemented in ahci was incorrect. On AHCI receving and processing FISes and raising interrupts are not interlocked and spurious interrupts are expected. For example, if an interrupt occurs while interrupt handler is running and the running interrupt handler handles the event the new IRQ indicated, after IRQ handler finishes, it will be executed again because IRQ pending bit is set by the new interrupt but there won't be anything to process. Please read the following message for more information. http://article.gmane.org/gmane.linux.ide/26012 This patch... * Removes all spurious IRQ whining from ahci. Spurious NCQ completion detection was completely wrong. Spurious D2H Register FIS taught us that some early drives send spurious D2H Register FIS with I bit set while NCQ commands are in progress but none of recent drives does that and even the ones which show such behavior can do NCQ fine. * Kills all NCQ blacklist entries which were added because of spurious NCQ completions. I tracked down each commit and verified all removed ones are actually added because of spurious completions. WD740ADFD-00NLR1 wasn't deleted but moved upward because the drive not only had spurious NCQ completions but also is slow on sequential data transfers if NCQ is enabled. Maxtor 7V300F0 was added by 0e3dbc01 from Alan Cox. I can only find evidences that the drive only had troubles with spuruious completions by searching the mailing list. This entry needs to be verified and removed if it doesn't have other NCQ related problems. Signed-off-by:

ICH6 R/Ms share PCI ID between piix and ahci modes and we've been allowing ahci to attach regardless of how BIOS configured it. However, enabling AHCI mode when the controller is in combined mode can result in unexpected behavior. Don't attach if the controller is in combined mode. Signed-off-by:
