Merge tag 'powerpc-5.8-1' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux
Pull powerpc updates from Michael Ellerman:
- Support for userspace to send requests directly to the on-chip GZIP accelerator on Power9.
- Rework of our lockless page table walking (__find_linux_pte()) to make it safe against parallel page table manipulations without relying on an IPI for serialisation.
- A series of fixes & enhancements to make our machine check handling more robust.
- Lots of plumbing to add support for "prefixed" (64-bit) instructions on Power10.
- Support for using huge pages for the linear mapping on 8xx (32-bit).
- Remove obsolete Xilinx PPC405/PPC440 support, and an associated sound driver.
- Removal of some obsolete 40x platforms and associated cruft.
- Initial support for booting on Power10.
- Lots of other small features, cleanups & fixes.

Merge "Use hugepages to map kernel mem on 8xx" into next
Merge Christophe's large series to use huge pages for the linear mapping on 8xx.
From his cover letter:
The main purpose of this big series is to: - reorganise huge page handling to avoid using mm_slices. - use huge pages to map kernel memory on the 8xx.
The 8xx supports 4 page sizes: 4k, 16k, 512k and 8M. It uses 2 Level page tables, PGD having 1024 entries, each entry covering 4M address space. Then each page table has 1024 entries.
At the time being, page sizes are managed in PGD entries, implying the use of mm_slices as it can't mix several pages of the same size in one page table.
The first purpose of this series is to reorganise things so that standard page tables can also handle 512k pages. This is done by adding a new _PAGE_HUGE flag which will be copied into the Level 1 entry in the TLB miss handler. That done, we have 2 types of pages: - PGD entries to regular page tables handling 4k/16k and 512k pages - PGD entries to hugepd tables handling 8M pages.
There is no need to mix 8M pages with other sizes, because a 8M page will use more than what a single PGD covers.
Then comes the second purpose of this series. At the time being, the 8xx has implemented special handling in the TLB miss handlers in order to transparently map kernel linear address space and the IMMR using huge pages by building the TLB entries in assembly at the time of the exception.
As mm_slices is only for user space pages, and also because it would anyway not be convenient to slice kernel address space, it was not possible to use huge pages for kernel address space. But after step one of the series, it is now more flexible to use huge pages.
This series drop all assembly 'just in time' handling of huge pages and use huge pages in page tables instead.
Once the above is done, then comes icing on the cake: - Use huge pages for KASAN shadow mapping - Allow pinned TLBs with strict kernel rwx - Allow pinned TLBs with debug pagealloc
Then, last but not least, those modifications for the 8xx allows the following improvement on book3s/32: - Mapping KASAN shadow with BATs - Allowing BATs with debug pagealloc
All this allows to considerably simplify TLB miss handlers and associated initialisation. The overhead of reading page tables is negligible compared to the reduction of the miss handlers.
While we were at touching pte_update(), some cleanup was done there too.
Tested widely on 8xx and 832x. Boot tested on QEMU MAC99.

powerpc/8xx: Drop CONFIG_8xx_COPYBACK option
CONFIG_8xx_COPYBACK was there to help disabling copyback cache mode for debuging hardware. But nobody will design new boards with 8xx now.
All 8xx platforms select it, so make it the default and remove the option.
Also remove the Mx_RESETVAL values which are pretty useless and hide the real value while reading code.

Merge tag 'powerpc-4.16-1' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux
Pull powerpc updates from Michael Ellerman: "Highlights:
- Enable support for memory protection keys aka "pkeys" on Power7/8/9 when using the hash table MMU.
- Extend our interrupt soft masking to support masking PMU interrupts as well as "normal" interrupts, and then use that to implement local_t for a ~4x speedup vs the current atomics-based implementation.
- A new driver "ocxl" for "Open Coherent Accelerator Processor Interface (OpenCAPI)" devices.
- Support for new device tree properties on PowerVM to describe hotpluggable memory and devices.
- Add support for CLOCK_{REALTIME/MONOTONIC}_COARSE to the 64-bit VDSO.
- Freescale updates from Scott: fixes for CPM GPIO and an FSL PCI erratum workaround, plus a minor cleanup patch.
As well as quite a lot of other changes all over the place, and small fixes and cleanups as always.
