This code is copying strings in 64 bit quantities, the device
returns them in big endian. As long as we store in big endian
IOW endian on both sides matches, we're good, so swap to_be64,
not from be64.
This fixes ~60 sparse warnings.

Marc Kleine-Budde says:
====================
pull-request: can-next 2020-12-14
All 7 patches are by me and target the m_can driver. First there are 4 cleanup
patches (fix link to doc, fix coding style, uniform variable name usage, mark
function as static). Then the driver is converted to
pm_runtime_resume_and_get(). The next patch lets the m_can class driver
allocate the driver's private data, to get rid of one level of indirection. And
the last patch consistently uses struct m_can_classdev as drvdata over all
binding drivers.

Upon route insertion and removal, it is needed to flush possibly cached
entries from the XM cache. Extend XM op context to carry information
needed for the flush. Implement the flush in delayed work since for HW
design reasons there is a need to wait 50usec before the flush can be
done. If during this time comes the same flush request, consolidate it
to the first one. Implement this queued flushes by a hashtable.

"Yet another large set of x86 interrupt management updates:
- Simplification and distangling of the MSI related functionality
- Let IO/APIC construct the RTE entries from an MSI message instead
of having IO/APIC specific code in the interrupt remapping drivers
- Make the retrieval of the parent interrupt domain (vector or remap

- Allow the handling of more than 255 CPUs without a virtualized

The current scheme allocates a DMA buffer as big as the requested
firmware package file and DMAs the contents to firmware in one
operation. The buffer size can be several hundred kilo bytes and
the driver may not be able to allocate the memory. This will cause
firmware upgrade to fail.
Improve the scheme by using smaller DMA blocks and calling firmware to
DMA each block in a batch mode. Older firmware can cause excessive
NVRAM erases if the block size is too small so we try to allocate a
256K buffer to begin with and size it down successively if we cannot
allocate the memory.

without checking queue fullness.

The 6220 and 6250 switches do not have a learn2all bit in global1, ATU
control register; bit 3 is reserverd.
On the switches that do have that bit, it is used to control whether
learning frames are sent out the ports that have the message_port bit
set. So rather than adding yet another chip method, use the existence
of the ->port_setup_message_port method as a proxy for determining
whether the learn2all bit exists (and should be set).

git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 updates from Catalin Marinas:
- Expose tag address bits in siginfo. The original arm64 ABI did not
expose any of the bits 63:56 of a tagged address in siginfo. In the
presence of user ASAN or MTE, this information may be useful. The
implementation is generic to other architectures supporting tags
(like SPARC ADI, subject to wiring up the arch code). The user will
have to opt in via sigaction(SA_EXPOSE_TAGBITS) so that the extra
bits, if available, become visible in si_addr.
- Default to 32-bit wide ZONE_DMA. Previously, ZONE_DMA was set to the
lowest 1GB to cope with the Raspberry Pi 4 limitations, to the
detriment of other platforms. With these changes, the kernel scans
the Device Tree dma-ranges and the ACPI IORT information before
deciding on a smaller ZONE_DMA.
- Strengthen READ_ONCE() to acquire when CONFIG_LTO=y. When building
with LTO, there is an increased risk of the compiler converting an
address dependency headed by a READ_ONCE() invocation into a control
dependency and consequently allowing for harmful reordering by the
CPU.
- Add CPPC FFH support using arm64 AMU counters.
- set_fs() removal on arm64. This renders the User Access Override
(UAO) ARMv8 feature unnecessary.
- Perf updates: PMU driver for the ARM DMC-620 memory controller, sysfs
identifier file for SMMUv3, stop event counters support for i.MX8MP,
enable the perf events-based hard lockup detector.
- Reorganise the kernel VA space slightly so that 52-bit VA
configurations can use more virtual address space.
- Improve the robustness of the arm64 memory offline event notifier.
- Pad the Image header to 64K following the EFI header definition
updated recently to increase the section alignment to 64K.
- Support CONFIG_CMDLINE_EXTEND on arm64.
- Do not use tagged PC in the kernel (TCR_EL1.TBID1==1), freeing up 8
bits for PtrAuth.
- Switch to vmapped shadow call stacks.
- Miscellaneous clean-ups.

Merge radeon and amdgpu fixes for boot problems.
The drm merge ended up causing my AMD workstation to not boot. When
reporting this, Alex Deucher correctly blamed commit 28a68f828266
("drm/radeon/ttm: use multihop") and pointed to these two fixes that
were already in the drm-misc tree:
95e3d610d35c ("drm/radeon: fix check order in radeon_bo_move")
aefec40938e4 ("drm/amdgpu: fix check order in amdgpu_bo_move")
Since I hate doing merges with a known-bad base, I've cherry-picked
these fixes into a branch of their own, just to be able to continue my
merge window. The original commits will eventually come in as
duplicates through the normal channels, but in the meantime we have a
tree that isn't broken with basically every AMD GPU out there.

For libceph, this ensures that libceph instance sharing (share option)
continues to work. For rbd, this avoids blocklisting alive lock owners
(locker addr is always LEGACY, while watcher addr is ANY in nautilus).

Pull MD regression reverts from Mike Snitzer:
"A cascade of MD reverts occurred late in the v5.10-rcX cycle due to MD
raid10 discard optimizations having introduced potential for
corruption.
Those reverts exposed a dm-raid.c compiler warning that wasn't ever
knowingly introduced. That min_not_zero() type mismatch warning was
thought to be safely fixed simply by changing 'struct mddev' to use
'unsigned int' rather than int for chunk_sectors members in that
struct.
I proposed either using a cast local to dm-raid.c but thought changing
the type to 'unsigned int' more correct. While that may be, not enough
testing was paired with code review associated with making that
change. As such we were left exposed and the result was a report that
with v5.10 btrfs on MD RAID6 failed to mount:
https://lkml.org/lkml/2020/12/14/7
Given that report, it is justified to simply revert these offending
commits. stable@ has already taken steps to revert these for 5.10.1 -
this just makes sure mainline does so too"
