mainlining shenanigans
4645453cef
One notable fix for our change to split pt_regs between user/kernel, we forgot to update BPF to use the user-visible type which was an ABI break for BPF programs. A slightly ugly but minimal fix to do_syscall_trace_enter() so that we use tracehook_report_syscall_entry() properly. We'll rework the code in next to avoid the empty if body. Seven commits fixing bugs in the new papr_scm (Storage Class Memory) driver. The driver was finally able to be tested on the other hypervisor which exposed several bugs. The fixes are all fairly minimal at least. Fix a crash in our MSI code if an MSI-capable device is plugged into a non-MSI capable PHB, only seen on older hardware (MPC8378). Fix our legacy serial code to look for "stdout-path" since the device trees were updated to use that instead of "linux,stdout-path". A change to the COFF zImage code to fix booting old powermacs. A couple of minor build fixes. Thanks to: Benjamin Herrenschmidt, Daniel Axtens, Dmitry V. Levin, Elvira Khabirova, Oliver O'Halloran, Paul Mackerras, Radu Rendec, Rob Herring, Sandipan Das. -----BEGIN PGP SIGNATURE----- iQIcBAABAgAGBQJcE7YGAAoJEFHr6jzI4aWA/rAP/2k8NqgbkfKMdY/nHQ/+Tvwu 6EdKZ5dMi875380TomrP80mIyAAwwtN/c1MmJT7plZRCwYcuhGk4UnQjTRcNzrfK Q7SokdMAzSjSDaj7VPiVdpJ6yVaedZYmsRe9m+uP7frmcHr9KL4vjgDn3z8IL8bV I46dvjuSCvgWhFvhXkxf9PHIsC+sP4Z6JRNVhyBjlzQHZiGparq238H8jJVsNHRs f/fsze0z6m3S6dVKEZKZyDlCb3TkP+DjuXpv4hbT9nvnOY132kqO53L++7rQ2YvV TNkabwFfj+p/DnrXXH7OHNkvnDW4cy3KjhyStOnTH5lxYYVYNd5vnjj1AnXa37xE GCBFiHExEHbdG6vifwBmQjvoNRPf6Kh4RGYuRMm8ci7W0WUmq00LKZhxeLbwoou9 1K7lNp0JwLHgqOxCSy9liwNV7YQp1upvC/caQ1qE/ZISnUOXMLxomVfmGQYW51Xc 0/OXCdmacViA0RGatrGSScMO+CTNG0Wa3pm+fo/ufLahxspTDMVdJgs/kEfCAGeN 6BruUoEvm6wAOsPF8+zDumYOpUN9cD7tOQ573B2pMbJYIv3HJxRMDHYGBSijEgRK xy8BbQ0ZtxgfILjIuA95QfGQ5V35ZjugQfM4mt33GPrQ/qIV9SJ+/zZJNISSqaKI Y1xgZdJeVbECA9YYswRK =wI/G -----END PGP SIGNATURE----- Merge tag 'powerpc-4.20-4' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux Pull powerpc fixes from Michael Ellerman: "One notable fix for our change to split pt_regs between user/kernel, we forgot to update BPF to use the user-visible type which was an ABI break for BPF programs.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
