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. 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.

lkml and Linus gained a CoC, and it's serious this time. Which means my no 1 reason for declining to officially step up as drm maintainer is gone, and I didn't find any new good excuse. I chatted with a few people in private already, and the biggest concern is that I mislay my community hat and start running around with my intel hat only. Or some other convenient abuse of trust. That's why this patch doesn't just need a lot of acks that mean "yeah seems fine to me", but a lot of acks that mean "yeah we'll tell you when you're over the line and usurp you from that comfy chair if you don't get it". Which I think we've been done a fairly good job here at dri-devel in general, but better to be clear. Rough idea is that I'll do this for maybe 2-3 years, helping Dave figure out a group model for drm overall. And getting the tooling and infrastructure for that off the ground. Then step down again because some other shiny thing that needs chasing. Of course as plans tend to do, this one will probably pan out a bit different in reality.

When support for bonding of RoCE devices was added, there was necessarily a link between the RoCE device and the paired netdevice that was part of the bond. If you remove the mlx4_en module, that paired association is broken (the RoCE device is still present but the paired netdevice has been released). We need to account for this in is_upper_ndev_bond_master_filter() and filter out those links with a broken pairing or else we later oops in netdev_next_upper_dev_rcu().

Adding an extra MI_STORE_DWORD_IMM to the gpu relocation path for gen3 was good, but still not good enough. To survive 24+ hours under test we needed to perform not one, not two but three extra store-dw. Doing so for each GPU relocation was a little unsightly and since we need to worry about userspace hitting the same issues, we should apply the dummy store-dw into the EMIT_FLUSH.

Currently we allocate a scratch page for each engine, but since we only ever write into it for post-sync operations, it is not exposed to userspace nor do we care for coherency. As we then do not care about its contents, we can use one page for all, reducing our allocations and avoid complications by not assuming per-engine isolation. For later use, it simplifies engine initialisation (by removing the allocation that required struct_mutex!) and means that we can always rely on there being a scratch page. v2: Check that we allocated a large enough scratch for I830 w/a Fixes: 06e562e7f515 ("drm/i915/ringbuffer: Delay after EMIT_INVALIDATE for gen4/gen5") # v4.18.20 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=108850Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Cc: Mika Kuoppala <mika.kuoppala@linux.intel.com> Reviewed-by: Mika Kuoppala <mika.kuoppala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20181204141522.13640-1-chris@chris-wilson.co.uk Cc: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Cc: <stable@vger.kernel.org> # v4.18.20+ (cherry picked from commit 51797499) [Joonas: Use new function in gen9_init_indirectctx_bb too] Signed-off-by: Joonas Lahtinen <joonas.lahtinen@linux.intel.com>

Braswell is really picky about having our writes posted to memory before we execute or else the GPU may see stale values. A wmb() is insufficient as it only ensures the writes are visible to other cores, we need a full mb() to ensure the writes are in memory and visible to the GPU. The most frequent failure in flushing before execution is that we see stale PTE values and execute the wrong pages.

Commit f149b315 ("signal: Never allocate siginfo for SIGKILL or SIGSTOP") means that the seccomp selftest cannot check si_pid under SIGSTOP anymore. Since it's believed[1] there are no other userspace things depending on the old behavior, this removes the behavioral check in the selftest, since it's more a "extra" sanity check (which turns out, maybe, not to have been useful to test).

When FUSE_OPEN returns ENOSYS, the no_open bit is set on the connection. Because the FUSE_RELEASE and FUSE_RELEASEDIR paths share code, this incorrectly caused the FUSE_RELEASEDIR request to be dropped and never sent to userspace. Pass an isdir bool to distinguish between FUSE_RELEASE and FUSE_RELEASEDIR inside of fuse_file_put.

Sending a DM event before a thin-pool state change is about to happen is a bug. It wasn't realized until it became clear that userspace response to the event raced with the actual state change that the event was meant to notify about. Fix this by first updating internal thin-pool state to reflect what the DM event is being issued about. This fixes a long-standing racey/buggy userspace device-mapper-test-suite 'resize_io' test that would get an event but not find the state it was looking for -- so it would just go on to hang because no other events caused the test to reevaluate the thin-pool's state.

The following commands will cause a memory leak: # cd /sys/kernel/tracing # mkdir instances/foo # echo schedule > instance/foo/set_ftrace_filter # rmdir instances/foo The reason is that the hashes that hold the filters to set_ftrace_filter and set_ftrace_notrace are not freed if they contain any data on the instance and the instance is removed. Found by kmemleak detector. Cc: stable@vger.kernel.org Fixes: 591dffda ("ftrace: Allow for function tracing instance to filter functions") Signed-off-by: Steven Rostedt (VMware) <rostedt@goodmis.org>
