We see multiple issues with the implementation/interface to compute
whether a memory block can be offlined (exposed via
/sys/devices/system/memory/memoryX/removable) and would like to simplify
it (remove the implementation).
1. It runs basically lockless. While this might be good for performance,
we see possible races with memory offlining that will require at
least some sort of locking to fix.
2. Nowadays, more false positives are possible. No arch-specific checks
are performed that validate if memory offlining will not be denied
right away (and such check will require locking). For example, arm64
won't allow to offline any memory block that was added during boot -
which will imply a very high error rate. Other archs have other
constraints.
3. The interface is inherently racy. E.g., if a memory block is detected
to be removable (and was not a false positive at that time), there is
still no guarantee that offlining will actually succeed. So any
caller already has to deal with false positives.
4. It is unclear which performance benefit this interface actually
provides. The introducing commit 5c755e9fd813 ("memory-hotplug: add
sysfs removable attribute for hotplug memory remove") mentioned
"A user-level agent must be able to identify which sections
of memory are likely to be removable before attempting the
potentially expensive operation."
However, no actual performance comparison was included.
Known users:
- lsmem: Will group memory blocks based on the "removable" property. [1]
- chmem: Indirect user. It has a RANGE mode where one can specify
removable ranges identified via lsmem to be offlined. However,
it also has a "SIZE" mode, which allows a sysadmin to skip the
manual "identify removable blocks" step. [2]
- powerpc-utils: Uses the "removable" attribute to skip some memory
blocks right away when trying to find some to offline+remove.
However, with ballooning enabled, it already skips this
information completely (because it once resulted in many false
negatives). Therefore, the implementation can deal with false
positives properly already. [3]
According to Nathan Fontenot, DLPAR on powerpc is nowadays no longer
driven from userspace via the drmgr command (powerpc-utils). Nowadays
it's managed in the kernel - including onlining/offlining of memory
blocks - triggered by drmgr writing to /sys/kernel/dlpar. So the
affected legacy userspace handling is only active on old kernels. Only
very old versions of drmgr on a new kernel (unlikely) might execute
slower - totally acceptable.
With CONFIG_MEMORY_HOTREMOVE, always indicating "removable" should not
break any user space tool. We implement a very bad heuristic now.
Without CONFIG_MEMORY_HOTREMOVE we cannot offline anything, so report
"not removable" as before.
Original discussion can be found in [4] ("[PATCH RFC v1] mm:
is_mem_section_removable() overhaul").
Other users of is_mem_section_removable() will be removed next, so that
we can remove is_mem_section_removable() completely.

The firmware source, wanxlfw.S, is currently compiled by the combo of
$(CPP) and $(M68KAS). This is not what we usually do for compiling *.S
files. In fact, this Makefile is the only user of $(AS) in the kernel
build.
Instead of combining $(CPP) and (AS) from different tool sets, using
$(M68KCC) as an assembler driver is simpler, and saner.

As far as I understood from the Kconfig help text, this build rule is
used to rebuild the driver firmware, which runs on an old m68k-based
chip. So, you need m68k tools for the firmware rebuild.
wanxl.c is a PCI driver, but CONFIG_M68K does not select CONFIG_HAVE_PCI.
So, you cannot enable CONFIG_WANXL_BUILD_FIRMWARE for ARCH=m68k. In other
words, ifeq ($(ARCH),m68k) is false here.
I am keeping the dead code for now, but rebuilding the firmware requires
'as68k' and 'ld68k', which I do not have in hand.
Instead, the kernel.org m68k GCC [1] successfully built it.
Allowing a user to pass in CROSS_COMPILE_M68K= is handier.

Commit:
ec93fc371f014a6f ("efi/libstub: Add support for loading the initrd from a device path")
added a diagnostic print to the ARM version of the EFI stub that
reports whether an initrd has been loaded that was passed
via the command line using initrd=.
However, it failed to take into account that, for historical reasons,
the file loading routines return EFI_SUCCESS when no file was found,
and the only way to decide whether a file was loaded is to inspect
the 'size' argument that is passed by reference. So let's inspect
this returned size, to prevent the print from being emitted even if
no initrd was loaded at all.

Commit:
9f9223778ef3 ("efi/libstub/arm: Make efi_entry() an ordinary PE/COFF entrypoint")
did some code refactoring to get rid of the EFI entry point assembler
code, and in the process, it got rid of the assignment of image_addr
to the value of _text. Instead, it switched to using the image_base
field of the efi_loaded_image struct provided by UEFI, which should
contain the same value.
However, Michael reports that this is not the case: older GRUB builds
corrupt this value in some way, and since we can easily switch back to
referring to _text to discover this value, let's simply do that.
While at it, fix another issue in commit 9f9223778ef3, which may result
in the unassigned image_addr to be misidentified as the preferred load
offset of the kernel, which is unlikely but will cause a boot crash if
it does occur.
Finally, let's add a warning if the _text vs. image_base discrepancy is
detected, so we can tell more easily how widespread this issue actually
is.

Changing the MTU for this switch means altering the
DEV_GMII:MAC_CFG_STATUS:MAC_MAXLEN_CFG field MAX_LEN, which in turn
limits the size of frames that can be received.
Special accounting needs to be done for the DSA CPU port (NPI port in
hardware terms). The NPI port configuration needs to be held inside the
private ocelot structure, since it is now accessed from multiple places.

On this switch, the frame length enforcements are performed by the
ingress policers. There are 2 types of those: regular L2 (also called
best-effort) and Virtual Link policers (an ARINC664/AFDX concept for
defining L2 streams with certain QoS abilities). To avoid future
confusion, I prefer to call the reset reason "Best-effort policers",
even though the VL policers are not yet supported.
We also need to change the setup of the initial static config, such that
DSA calls to .change_mtu (which are expensive) become no-ops and don't
reset the switch 5 times.
A driver-level decision is to unconditionally allow single VLAN-tagged
traffic on all ports. The CPU port must accept an additional VLAN header
for the DSA tag, which is again a driver-level decision.
The policers actually count bytes not only from the SDU, but also from
the Ethernet header and FCS, so those need to be accounted for as well.

Third set of patches for v5.7. Nothing really special this time,

When pulling this to net-next there's again a conflict in:

To solve this drop these three lines from the conflict (the first hunk
from "HEAD") as the whole AX200 block was moved above in the same
file:
IWL_DEV_INFO(0x2723, 0x1653, iwl_ax200_cfg_cc, iwl_ax200_killer_1650w_name),

IWL_DEV_INFO(0x2723, IWL_CFG_ANY, iwl_ax200_cfg_cc, iwl_ax200_name),
And keep all the __IWL_DEV_INFO() entries (the second hunk). In other
words, take everything from wireless-drivers-next. When running 'git

* handle RX fragments
* enable PN offload
* add support for HE BSS color

OSN devices currently spend an awful long time in qeth_l2_set_online()
until various unsupported HW cmds time out. This has been broken for
over two years, ever since
commit d22ffb5a712f ("s390/qeth: fix IPA command submission race")
triggered a FW bug in cmd processing.
Prior to commit 782e4a792147 ("s390/qeth: don't poll for cmd IO completion"),
this wait for timeout would have even been spent busy-polling.
The offending patch was picked up by stable and all relevant distros,
and yet noone noticed.
OSN setups only ever worked in combination with an out-of-tree blob, and
the last machine that even offered HW with OSN support was released back
in 2015.
Rather than attempting to work-around this FW issue for no actual gain,
add a deprecation warning so anyone who still wants to maintain this
part of the code can speak up. Else rip it all out in 2021.

The static array 'mlxsw_afk_element_infos' in 'core_acl_flex_keys.h' is
copied to each file that includes the header, but not all use it. This
results in the following warnings when compiling with W=1:
drivers/net/ethernet/mellanox/mlxsw//core_acl_flex_keys.h:76:44:
warning: ‘mlxsw_afk_element_infos’ defined but not used
[-Wunused-const-variable=]
One way to suppress the warning is to mark the array with
'__maybe_unused', but another option is to remove it from the header
file entirely.
Change 'struct mlxsw_afk_element_inst' to store the key to the array
('element') instead of the array value keyed by 'element'. Adjust the
different users accordingly.

In merge commit 50853808ff4a ("Merge branch
'mlxsw-Prepare-for-VLAN-aware-bridge-w-VxLAN'") I flipped mlxsw to use
emulated 802.1Q FIDs and correspondingly emulated VLAN RIFs. This means
that the non-emulated variants are no longer used. Remove them and
suppress the following warnings when compiling with W=1:

git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull ARM DT and driver fixes from Arnd Bergmann:
"For the devicetree files, there are a total of 20 patches, almost
entirely for 32-bit machines:
- The Allwinner/sun9i r40 SoC dtsi file contains a number of issues,
both for correctness and for style that are addressed in separate
patches. This causes most of the changed lines of the DT updates
this time.
- More Allwinner updates fixing the identification of the security
system on sun8i/A33, a recent regression of the A83t ethernet, and
a few board specific issues on the TBS-A711 macine.
- Several bug fixes for OMAP dts files, most notably fixing the
timings for the NAND flash on the Nokia N900 that regressed a while
ago after the move to configuring them from DT. Some other OMAPs
now set the correct dma limits on the L3 bus, and a regression fix
addresses lost Ethernet on dm814x
- One incorrect setting in the newly added Raspberry Pi Zero W that
may cause issues with the SD card controller.
- A missing property on the bcm2835 firmware node caused incorrect
DMA settings.
- An old bug on the oxnas platform causing spurious interrupts is
finally addressed.
- A regression on the Exynos Midas board broke the OLED panel power
supply.
- The i.MX6 phycore SoM specified the wrong voltage for the SoC, this
is now set to the values from the datasheet.
- Some 64-bit machines use a deprecated string to identify the PSCI
firmware.
There are also several small code fixes addressing mostly serious
issues:
- Fix the sunxi rsb bus access to no longer return incorrect data
when mixing 8 and 16 bit I/O.
- Fix a suspend/resume regression on the OMAP2+ lcdc from a missing
quirk in the ti-sysc driver
- Fix a NULL pointer access from a race in the fsl dpio driver
- Fix a v5.5 regression in the exynos-chipid driver that caused an
invalid error code probing the device on non-exynos platforms
- Fix an out-of-bounds access in the AMD TEE driver"

This patch adds two new tracpoints for null_blk_zoned.c that allows us
to trace report-zones, zone-mgmt-op and zone-write operations which has
direct effect on the zone condition state machine.
Also, we update drivers/block/Makefile so that new null_blk related
tracefiles can be compiled.

"A handful of clk driver fixes.
Mostly they're around the i.MX drivers fixing the parents of a few

Besides that we have a TI driver fix for the RTC parent and a fix for
the basic gate type registration functions introduced this release
where they didn't actually pass the arguments in the right places to
the multiplexer function down below"

Current make_request based drivers use either blk_alloc_queue_node or
blk_alloc_queue to allocate a queue, and then set up the make_request_fn
function pointer and a few parameters using the blk_queue_make_request
helper. Simplify this by passing the make_request pointer to
blk_alloc_queue, and while at it merge the _node variant into the main
helper by always passing a node_id, and remove the superfluous gfp_mask
parameter. A lower-level __blk_alloc_queue is kept for the blk-mq case.
