My randconfig tests on linux-next showed a newly introduced warning:
drivers/gpu/drm/amd/amdgpu/amdgpu_object.c: In function 'amdgpu_bo_create_restricted':
drivers/gpu/drm/amd/amdgpu/amdgpu_object.c:377:2: error: #warning Please enable CONFIG_MTRR and CONFIG_X86_PAT for better performance thanks to write-combining [-Werror=cpp]
Generally speaking, warnings about bad kernel configuration are not particularly
helpful. We could enforce the selection of X86_PAT through Kconfig, so the driver
cannot even be used unless it is enabled, or we could just rely on the runtime
warning that is also there.
In this version, I'm making the warning conditional on CONFIG_COMPILE_TEST, which
shuts it up for me, but not people that may actually want to run the kernel
as a compromize.

Gabriel C reports that it causes his machine to not boot, and we haven't
tracked down the reason for it yet. Since the bug it fixes has been
around for a longish time, we're better off reverting the fix for now.
Gabriel says:
"It hangs early and freezes with a lot RCU warnings.

mm/slub.c: fix random_seq offset destruction
cpumask: use nr_cpumask_bits for parsing functions
mm: avoid returning VM_FAULT_RETRY from ->page_mkwrite handlers
kernel/ucount.c: mark user_header with kmemleak_ignore()
Commit 210e7a43fa ("mm: SLUB freelist randomization") broke USB hub
initialisation as described in
https://bugzilla.kernel.org/show_bug.cgi?id=177551.
Bail out early from init_cache_random_seq if s->random_seq is already
initialised. This prevents destroying the previously computed
random_seq offsets later in the function.
If the offsets are destroyed, then shuffle_freelist will truncate
page->freelist to just the first object (orphaning the rest).

Commit 513e3d2d11 ("cpumask: always use nr_cpu_ids in formatting and
parsing functions") converted both cpumask printing and parsing
functions to use nr_cpu_ids instead of nr_cpumask_bits. While this was
okay for the printing functions as it just picked one of the two output
formats that we were alternating between depending on a kernel config,
doing the same for parsing wasn't okay.
nr_cpumask_bits can be either nr_cpu_ids or NR_CPUS. We can always use
nr_cpu_ids but that is a variable while NR_CPUS is a constant, so it can
be more efficient to use NR_CPUS when we can get away with it.
Converting the printing functions to nr_cpu_ids makes sense because it
affects how the masks get presented to userspace and doesn't break
anything; however, using nr_cpu_ids for parsing functions can
incorrectly leave the higher bits uninitialized while reading in these
masks from userland. As all testing and comparison functions use
nr_cpumask_bits which can be larger than nr_cpu_ids, the parsed cpumasks
can erroneously yield false negative results.
This made the taskstats interface incorrectly return -EINVAL even when
the inputs were correct.
Fix it by restoring the parse functions to use nr_cpumask_bits instead
of nr_cpu_ids.

Some ->page_mkwrite handlers may return VM_FAULT_RETRY as its return
code (GFS2 or Lustre can definitely do this). However VM_FAULT_RETRY
from ->page_mkwrite is completely unhandled by the mm code and results
in locking and writeably mapping the page which definitely is not what
the caller wanted.
Fix Lustre and block_page_mkwrite_ret() used by other filesystems
(notably GFS2) to return VM_FAULT_NOPAGE instead which results in
bailing out from the fault code, the CPU then retries the access, and we
fault again effectively doing what the handler wanted.

When drm_crtc_init_with_planes() was orignally added
(in drm_crtc.c, e13161af80
drm: Add drm_crtc_init_with_planes() (v2)), it only checked for "primary"
being non-null. If that was the case, it modified primary->possible_crtcs.
Then, when support for cursor planes was added
(fc1d3e44ef drm: Allow drivers to register
cursor planes with crtc), the same behaviour was implemented for cursor
planes.
vc4_plane_init() since its inception has passed 0xff as "possible_crtcs"
parameter to drm_universal_plane_init(). With a change in drm_crtc.c
(7abc7d4751 drm: don't override
possible_crtcs for primary/cursor planes) passing 0xff results in primary's
possible_crtcs set to 0xff (cursor was updated manually by vc4_crtc.c).
Consequently, it would be allowed to use the primary plane from CRTC 1 (for
example) on CRTC 0, which would result in the overlay and cursors being
buried.

Link layer protocols may unconditionally pull headers, as Ethernet

always lies in the skb linear segment. tpacket_snd has such a check.
Extend this to packet_snd.
Variable length link layer headers complicate the computation
somewhat. Here skb->len may be smaller than dev->hard_header_len.
Round up the linear length to be at least as long as the smallest of
the two.

The stack must not pass packets to device drivers that are shorter
than the minimum link layer header length.
Previously, packet sockets would drop packets smaller than or equal
to dev->hard_header_len, but this has false positives. Zero length
payload is used over Ethernet. Other link layer protocols support
variable length headers. Support for validation of these protocols
removed the min length check for all protocols.
Introduce an explicit dev->min_header_len parameter and drop all
packets below this value. Initially, set it to non-zero only for
Ethernet and loopback. Other protocols can follow in a patch to
net-next.

RTNETLINK answers: Operation not supported
The problem occurs when CONFIG_LWTUNNEL is not enabled and a multipath
route is submitted.
The point of lwtunnel_valid_encap_type_attr is catch modules that
need to be loaded before any references are taken with rntl held. With
CONFIG_LWTUNNEL disabled, there will be no modules to load so the
lwtunnel_valid_encap_type_attr stub should just return 0.

Remove references to private kernel header and defines from exported
ib_user_verb.h file.
The code snippet below is used to reproduce the issue:
#include <stdio.h>
#include <rdma/ib_user_verb.h>
int main(void)
{
printf("IB_USER_VERBS_ABI_VERSION = %d\n", IB_USER_VERBS_ABI_VERSION);
return 0;
}
It fails during compilation phase with an error:
➜ /tmp gcc main.c
main.c:2:31: fatal error: rdma/ib_user_verb.h: No such file or directory
#include <rdma/ib_user_verb.h>
^
compilation terminated.
