Pull more powerpc updates from Michael Ellerman: "The bulk of this is the series to make CONFIG_COMPAT user-selectable, it's been around for a long time but was blocked behind the syscall-in-C series. Plus there's also a few fixes and other minor things. Summary: - A fix for a crash in machine check handling on pseries (ie. guests) - A small series to make it possible to disable CONFIG_COMPAT, and turn it off by default for ppc64le where it's not used. - A few other miscellaneous fixes and small improvements.

powerpc/ps3: Convert half completion to rcuwait

2020-03-21T15:00:22Z

The PS3 notification interrupt and kthread use a hacked up completion to communicate. Since we're wanting to change the completion implementation and this is abuse anyway, replace it with a simple rcuwait since there is only ever the one waiter. AFAICT the kthread uses TASK_INTERRUPTIBLE to not increase loadavg, kthreads cannot receive signals by default and this one doesn't look different. Use TASK_IDLE instead.

Pull powerpc updates from Michael Ellerman: "This is a bit late, partly due to me travelling, and partly due to a power outage knocking out some of my test systems *while* I was travelling. - Initial support for running on a system with an Ultravisor, which is software that runs below the hypervisor and protects guests against some attacks by the hypervisor. - Support for building the kernel to run as a "Secure Virtual Machine", ie. as a guest capable of running on a system with an Ultravisor. - Some changes to our DMA code on bare metal, to allow devices with medium sized DMA masks (> 32 && < 59 bits) to use more than 2GB of DMA space. - Support for firmware assisted crash dumps on bare metal (powernv). - Two series fixing bugs in and refactoring our PCI EEH code. - A large series refactoring our exception entry code to use gas macros, both to make it more readable and also enable some future optimisations. As well as many cleanups and other minor features & fixups.

dma-mapping: provide a better default ->get_required_mask

2019-09-04T09:13:19Z

Most dma_map_ops instances are IOMMUs that work perfectly fine in 32-bits of IOVA space, and the generic direct mapping code already provides its own routines that is intelligent based on the amount of memory actually present. Wire up the dma-direct routine for the ARM direct mapping code as well, and otherwise default to the constant 32-bit mask. This way we only need to override it for the occasional odd IOMMU that requires 64-bit IOVA support, or IOMMU drivers that are more efficient if they can fall back to the direct mapping.

dma-mapping: explicitly wire up ->mmap and ->get_sgtable

2019-09-04T09:13:18Z

While the default ->mmap and ->get_sgtable implementations work for the majority of our dma_map_ops impementations they are inherently safe for others that don't use the page allocator or CMA and/or use their own way of remapping not covered by the common code. So remove the defaults if these methods are not wired up, but instead wire up the default implementations for all safe instances.

powerpc/ps3: replace __ioremap() by ioremap_prot()

2019-08-27T03:03:33Z

__ioremap() is similar to ioremap_prot() except that ioremap_prot() does a few sanity changes in addition. The flags used by PS3 are not impacted by those changes so for PS3 both functions are equivalent. At the same time, drop parts of the comment that have been invalid since commit e58e87adc8bf ("powerpc/mm: Update _PAGE_KERNEL_RO") Suggested-by: Christoph Hellwig Signed-off-by: Christophe Leroy Reviewed-by: Christoph Hellwig Signed-off-by: Michael Ellerman Link: https://lore.kernel.org/r/36bff5d875ff562889c5e12dab63e5d7c5d1fbd8.1566309262.git.christophe.leroy@c-s.fr
