Merge tag 'powerpc-5.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux

Pull powerpc updates from Michael Ellerman:
"Notable changes:

- Removal of the NPU DMA code, used by the out-of-tree Nvidia driver,
as well as some other functions only used by drivers that haven't
(yet?) made it upstream.

- A fix for a bug in our handling of hardware watchpoints (eg. perf
record -e mem: ...) which could lead to register corruption and
kernel crashes.

- Enable HAVE_ARCH_HUGE_VMAP, which allows us to use large pages for
vmalloc when using the Radix MMU.

- A large but incremental rewrite of our exception handling code to
use gas macros rather than multiple levels of nested CPP macros.

And the usual small fixes, cleanups and improvements.

Merge tag 'powerpc-4.20-1' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux

Pull powerpc updates from Michael Ellerman:
"Notable changes:

- A large series to rewrite our SLB miss handling, replacing a lot of
fairly complicated asm with much fewer lines of C.

- Following on from that, we now maintain a cache of SLB entries for
each process and preload them on context switch. Leading to a 27%
speedup for our context switch benchmark on Power9.

- Improvements to our handling of SLB multi-hit errors. We now print
more debug information when they occur, and try to continue running
by flushing the SLB and reloading, rather than treating them as
fatal.

- Enable THP migration on 64-bit Book3S machines (eg. Power7/8/9).

- Add support for physical memory up to 2PB in the linear mapping on
64-bit Book3S. We only support up to 512TB as regular system
memory, otherwise the percpu allocator runs out of vmalloc space.

- Add stack protector support for 32 and 64-bit, with a per-task
canary.

- Add support for PTRACE_SYSEMU and PTRACE_SYSEMU_SINGLESTEP.

- Support recognising "big cores" on Power9, where two SMT4 cores are
presented to us as a single SMT8 core.

- A large series to cleanup some of our ioremap handling and PTE
flags.

- Add a driver for the PAPR SCM (storage class memory) interface,
allowing guests to operate on SCM devices (acked by Dan).

- Changes to our ftrace code to handle very large kernels, where we
need to use a trampoline to get to ftrace_caller().

And many other smaller enhancements and cleanups.

- Add support for patching barrier_nospec in copy_from_user() and

- A couple of fixes for our data breakpoints on Book3S.

- A series from Nick optimising TLB/mm handling with the Radix MMU.

- Numerous small cleanups to squash sparse/gcc warnings from Mathieu

- Several series optimising various parts of the 32-bit code from

- Removal of support for two old machines, "SBC834xE" and "C2K"

* Add DEFERRED_STRUCT_PAGE_INIT - Let's see what breaks.
* Add PPC_MEMTRACE - Small powernv debugfs driver for getting hardware traces.
* Add MEMORY_FAILURE - Machine check exceptions can now drive memory failure.
* Turn on FANOTIFY - This is the current filesystem notification feature.
* Turn on SCOM_DEBUGFS - Handy for hardware/firmware debugging, security risk?
* Turn on async SCSI scanning - Let's see what breaks.
* Add MLX5 driver as a module - Popular demand.
* Add CRYPTO_CRCT10DIF_VPMSUM - POWER8 T10DIF acceleration.

* Make a bunch of USB hid drivers modules.
* Make SCSI SG, SR, and FC modules - FC is huge.
* Make video drivers except AST GPU modules - Also huge.
* Make PCI serial driver a module - Uncommon.
* Make more things modules, NFS FS, RAM disk, netconsole, MS-DOS fs.

* Get rid of /dev/port - Not used.
* Remove PPS and PTP subsystms - Unusual.
* Remove legacy BSD ttys - Long dead.
* Remove IDE - Deprecated and replaced with ATA.
* Remove WIRELESS - Until we get POWER9 laptops.
* Remove RAW - Long deprecated in favour of direct IO.
