0b24bdb73c UPSTREAM: arm64: sdei: Push IS_ENABLED() checks down to callee functions
Handling all combinations of the VMAP_STACK and SHADOW_CALL_STACK options
in sdei_arch_get_entry_point() makes the code difficult to read,
particularly when considering the error and cleanup paths.

Move the checking of these options into the callee functions, so that
they return early if the relevant option is not enabled.

27047fb22e UPSTREAM: scs: switch to vmapped shadow stacks
The kernel currently uses kmem_cache to allocate shadow call stacks,
which means an overflows may not be immediately detected and can
potentially result in another task's shadow stack to be overwritten.

This change switches SCS to use virtually mapped shadow stacks for
tasks, which increases shadow stack size to a full page and provides
more robust overflow detection, similarly to VMAP_STACK.

598670e2d0 ANDROID: sched: add trace hook to enable EAS for SMP systems
At present, EAS gets disabled when on ASYM Capacity systems
if all BIG or Little CPUs gets hot-plugged. Instead of disabling
EAS by default, add trace hook and let vendor decide if EAS should
be disabled or not.

A task can migrate either while it is waking or while it
is running via load balancer. Print the task status
i.e running or not in sched_migrate_task. This helps in
counting the different types of migrations without relying
on other trace events.

fd0328e37d UPSTREAM: mm/page_owner: record timestamp and pid
Collect the time for each allocation recorded in page owner so that
allocation "surges" can be measured.

Record the pid for each allocation recorded in page owner so that the
source of allocation "surges" can be better identified.

The above is very useful when doing memory analysis.  On a crash for
example, we can get this information from kdump (or ramdump) and parse it
to figure out memory allocation problems.

Please note that on x86_64 this increases the size of struct page_owner
from 16 bytes to 32.

Vlastimil: it's not a functionality intended for production, so unless
somebody says they need to enable page_owner for debugging and this
increase prevents them from fitting into available memory, let's not
complicate things with making this optional.

Free the pages parallely for a task that receives SIGKILL, from ULMK
process, using the oom_reaper. This freeing of pages will help to give
the pages to buddy system well advance.

Add the boot param, reap_mem_when_killed_by=, that configures the
process name, the kill signal to a process from which makes its memory
reaped by oom reaper.

As an example, when reap_mem_when_killed_by=lmkd, then all the processes
that receives the kill signal from lmkd is added to oom reaper.

Not initializing this param makes this feature disabled.

345c0b1cc4 UPSTREAM: driver core: Fix lockdep warning on wfs_lock
There's a potential deadlock with the following cycle:
wfs_lock --> device_links_lock --> kn->count

Fix this by simply dropping the lock around a list_empty() check that's
just exported to a sysfs file. The sysfs file output is an instantaneous
check anyway and the lock doesn't really add any protection.

b56c9e4cdf FROMLIST: scsi: ufs: fix livelock of ufshcd_clear_ua_wluns
When gate_work/ungate_work gets an error during hibern8_enter or exit,
 ufshcd_err_handler()
   ufshcd_scsi_block_requests()
   ufshcd_reset_and_restore()
     ufshcd_clear_ua_wluns() -> stuck
   ufshcd_scsi_unblock_requests()

In order to avoid it, ufshcd_clear_ua_wluns() can be called per recovery flows
such as suspend/resume, link_recovery, and error_handler.

a34582fecc ANDROID: rwsem: Export rwsem_waiter struct for loadable modules
The rwsem_waiter struct is needed in vendor hook alter_rwsem_list_add.
It has parameter sem which is a struct rw_semaphore (already export in
rwsem.h), inside the structure there is a wait_list to link
"struct rwsem_waiter" items. The task information in each item of the
wait_list is needed to be referenced in vendor loadable modules.

4eae6d1947 ANDROID: vendor_hook: modify cpuidle vendor hook
When entering cluster-wide or system-wide power mode, Exynos cpu
power management driver checks the next hrtimer events of cpu
composing the power domain to prevent unnecessary attempts to enter
the power mode. Since struct cpuidle_device has next_hrtimer, it
can be solved by passing cpuidle device as a parameter of vh.

In order to improve responsiveness, it is necessary to prevent
entering the deep idle state in boosting scenario. So, vendor
driver should be able to control the idle state.

Due to above requirements, the parameters required for idle enter
and exit different, so the vendor hook is separated into
cpu_idle_enter and cpu_idle_exit.

700d098ace x86/CPU/AMD: Save AMD NodeId as cpu_die_id
[ Upstream commit 028c221ed1 ]

AMD systems provide a "NodeId" value that represents a global ID
indicating to which "Node" a logical CPU belongs. The "Node" is a
physical structure equivalent to a Die, and it should not be confused
with logical structures like NUMA nodes. Logical nodes can be adjusted
based on firmware or other settings whereas the physical nodes/dies are
fixed based on hardware topology.

The NodeId value can be used when a physical ID is needed by software.

Save the AMD NodeId to struct cpuinfo_x86.cpu_die_id. Use the value
from CPUID or MSR as appropriate. Default to phys_proc_id otherwise.
Do so for both AMD and Hygon systems.

Drop the node_id parameter from cacheinfo_*_init_llc_id() as it is no
longer needed.

Update the x86 topology documentation.

bb25fd4926 drm/edid: fix objtool warning in drm_cvt_modes()
commit d652d5f1ee upstream.

Commit 991fcb77f4 ("drm/edid: Fix uninitialized variable in
drm_cvt_modes()") just replaced one warning with another.

The original warning about a possibly uninitialized variable was due to
the compiler not being smart enough to see that the case statement
actually enumerated all possible cases.  And the initial fix was just to
add a "default" case that had a single "unreachable()", just to tell the
compiler that that situation cannot happen.

However, that doesn't actually fix the fundamental reason for the
problem: the compiler still doesn't see that the existing case
statements enumerate all possibilities, so the compiler will still
generate code to jump to that unreachable case statement.  It just won't
complain about an uninitialized variable any more.

So now the compiler generates code to our inline asm marker that we told
it would not fall through, and end end result is basically random.  We
have created a bridge to nowhere.

And then, depending on the random details of just exactly what the
compiler ends up doing, 'objtool' might end up complaining about the
conditional branches (for conditions that cannot happen, and that thus
will never be taken - but if the compiler was not smart enough to figure
that out, we can't expect objtool to do so) going off in the weeds.

So depending on how the compiler has laid out the result, you might see
something like this:

    drivers/gpu/drm/drm_edid.o: warning: objtool: do_cvt_mode() falls through to next function drm_mode_detailed.isra.0()

and now you have a truly inscrutable warning that makes no sense at all
unless you start looking at whatever random code the compiler happened
to generate for our bare "unreachable()" statement.

IOW, don't use "unreachable()" unless you have an _active_ operation
that generates code that actually makes it obvious that something is not
reachable (ie an UD instruction or similar).

Solve the "compiler isn't smart enough" problem by just marking one of
the cases as "default", so that even when the compiler doesn't otherwise
see that we've enumerated all cases, the compiler will feel happy and
safe about there always being a valid case that initializes the 'width'
variable.

This also generates better code, since now the compiler doesn't generate
comparisons for five different possibilities (the four real ones and the
one that can't happen), but just for the three real ones and "the rest"
(which is that last one).

A smart enough compiler that sees that we cover all the cases won't care.

92ee9b9fa8 null_blk: Fix zone size initialization
commit 0ebcdd702f upstream.

For a null_blk device with zoned mode enabled is currently initialized
with a number of zones equal to the device capacity divided by the zone
size, without considering if the device capacity is a multiple of the
zone size. If the zone size is not a divisor of the capacity, the zones
end up not covering the entire capacity, potentially resulting is out
of bounds accesses to the zone array.

Fix this by adding one last smaller zone with a size equal to the
remainder of the disk capacity divided by the zone size if the capacity
is not a multiple of the zone size. For such smaller last zone, the zone
capacity is also checked so that it does not exceed the smaller zone
size.

2bbb320656 Revert: "ring-buffer: Remove HAVE_64BIT_ALIGNED_ACCESS"
commit adab66b71a upstream.

It was believed that metag was the only architecture that required the ring
buffer to keep 8 byte words aligned on 8 byte architectures, and with its
removal, it was assumed that the ring buffer code did not need to handle
this case. It appears that sparc64 also requires this.

The following was reported on a sparc64 boot up:

   kernel: futex hash table entries: 65536 (order: 9, 4194304 bytes, linear)
   kernel: Running postponed tracer tests:

450fc74de1 remoteproc: sysmon: Ensure remote notification ordering
commit 138a6428ba upstream.

The reliance on the remoteproc's state for determining when to send
sysmon notifications to a remote processor is racy with regard to
concurrent remoteproc operations.

Further more the advertisement of the state of other remote processor to
a newly started remote processor might not only send the wrong state,
but might result in a stream of state changes that are out of order.

Address this by introducing state tracking within the sysmon instances
themselves and extend the locking to ensure that the notifications are
consistent with this state.

3f4b60a70c regulator: axp20x: Fix DLDO2 voltage control register mask for AXP22x
commit 291de1d102 upstream.

When I use the axp20x chip to power my SDIO device on the 5.4 kernel,
the output voltage of DLDO2 is wrong. After comparing the register
manual and source code of the chip, I found that the mask bit of the
driver register of the port was wrong. I fixed this error by modifying
the mask register of the source code. This error seems to be a copy
error of the macro when writing the code. Now the voltage output of
the DLDO2 port of axp20x is correct. My development environment is
Allwinner A40I of arm architecture, and the kernel version is 5.4.

94bc6f5e2c of: fix linker-section match-table corruption
commit 5812b32e01 upstream.

Specify type alignment when declaring linker-section match-table entries
to prevent gcc from increasing alignment and corrupting the various
tables with padding (e.g. timers, irqchips, clocks, reserved memory).

This is specifically needed on x86 where gcc (typically) aligns larger
objects like struct of_device_id with static extent on 32-byte
boundaries which at best prevents matching on anything but the first
entry. Specifying alignment when declaring variables suppresses this
optimisation.

Here's a 64-bit example where all entries are corrupt as 16 bytes of
padding has been inserted before the first entry:

	ffffffff8266b4b0 D __clk_of_table
	ffffffff8266b4c0 d __of_table_fixed_factor_clk
	ffffffff8266b5a0 d __of_table_fixed_clk
	ffffffff8266b680 d __clk_of_table_sentinel

And here's a 32-bit example where the 8-byte-aligned table happens to be
placed on a 32-byte boundary so that all but the first entry are corrupt
due to the 28 bytes of padding inserted between entries:

	812b3ec0 D __irqchip_of_table
	812b3ec0 d __of_table_irqchip1
	812b3fa0 d __of_table_irqchip2
	812b4080 d __of_table_irqchip3
	812b4160 d irqchip_of_match_end

Verified on x86 using gcc-9.3 and gcc-4.9 (which uses 64-byte
alignment), and on arm using gcc-7.2.

Note that there are no in-tree users of these tables on x86 currently
(even if they are included in the image).

f2d7cffc20 tracing: Disable ftrace selftests when any tracer is running
commit 60efe21e59 upstream.

Disable ftrace selftests when any tracer (kernel command line options

starts running because selftest can disturb it.

Currently ftrace= and trace_events= are checked, but kprobe_events
has a different flag, and boot-time tracing didn't checked. This unifies
the disabled flag and all of those boot-time tracing features sets
the flag.

This also fixes warnings on kprobe-event selftest
(CONFIG_FTRACE_STARTUP_TEST=y and CONFIG_KPROBE_EVENTS=y) with boot-time
tracing (ftrace.event.kprobes.EVENT.probes) like below;

054c923fd3 platform/x86: intel-vbtn: Allow switch events on Acer Switch Alpha 12
commit fe60009903 upstream.

This 2-in-1 model (Product name: Switch SA5-271) features a SW_TABLET_MODE
that works as it would be expected, both when detaching the keyboard and
when folding it behind the tablet body.

It used to work until the introduction of the allow list at
commit 8169bd3e6e ("platform/x86: intel-vbtn: Switch to an allow-list
for SW_TABLET_MODE reporting"). Add this model to it, so that the Virtual
Buttons device announces the EV_SW features again.

16ecf8cecd libnvdimm/namespace: Fix reaping of invalidated block-window-namespace labels
commit 2dd2a1740e upstream.

A recent change to ndctl to attempt to reconfigure namespaces in place
uncovered a label accounting problem in block-window-type namespaces.
The ndctl "create.sh" test is able to trigger this signature:

 WARNING: CPU: 34 PID: 9167 at drivers/nvdimm/label.c:1100 __blk_label_update+0x9a3/0xbc0 [libnvdimm]
 [..]
 RIP: 0010:__blk_label_update+0x9a3/0xbc0 [libnvdimm]
 [..]
 Call Trace:
  uuid_store+0x21b/0x2f0 [libnvdimm]
  kernfs_fop_write+0xcf/0x1c0
  vfs_write+0xcc/0x380
  ksys_write+0x68/0xe0

When allocated capacity for a namespace is renamed (new UUID) the labels
with the old UUID need to be deleted. The ndctl behavior to always
destroy namespaces on reconfiguration hid this problem.

The immediate impact of this bug is limited since block-window-type
namespaces only seem to exist in the specification and not in any
shipping products. However, the label handling code is being reused for
other technologies like CXL region labels, so there is a benefit to
making sure both vertical labels sets (block-window) and horizontal
label sets (pmem) have a functional reference implementation in
libnvdimm.

4f826e66b0 memory: renesas-rpc-if: Return correct value to the caller of rpcif_manual_xfer()
commit a0453f4ed0 upstream.

In the error path of rpcif_manual_xfer() the value of ret is overwritten
by value returned by reset_control_reset() function and thus returning
incorrect value to the caller.

This patch makes sure the correct value is returned to the caller of
rpcif_manual_xfer() by dropping the overwrite of ret in error path.
Also now we ignore the value returned by reset_control_reset() in the
error path and instead print a error message when it fails.

c88347ae93 xenbus/xenbus_backend: Disallow pending watch messages
commit 9996bd4947 upstream.

'xenbus_backend' watches 'state' of devices, which is writable by
guests.  Hence, if guests intensively updates it, dom0 will have lots of
pending events that exhausting memory of dom0.  In other words, guests
can trigger dom0 memory pressure.  This is known as XSA-349.  However,
the watch callback of it, 'frontend_changed()', reads only 'state', so
doesn't need to have the pending events.

To avoid the problem, this commit disallows pending watch messages for
'xenbus_backend' using the 'will_handle()' watch callback.
