commit d57f9da890696af1484f4a47f7f123560197865a upstream.
struct bioctx includes the ref refcount_t to track the number of I/O
fragments used to process a target BIO as well as ensure that the zone
of the BIO is kept in the active state throughout the lifetime of the
BIO. However, since decrementing of this reference count is done in the
target .end_io method, the function bio_endio() must be called multiple
times for read and write target BIOs, which causes problems with the
value of the __bi_remaining struct bio field for chained BIOs (e.g. the
clone BIO passed by dm core is large and splits into fragments by the
block layer), resulting in incorrect values and inconsistencies with the
BIO_CHAIN flag setting. This is turn triggers the BUG_ON() call:
BUG_ON(atomic_read(&bio->__bi_remaining) <= 0);
in bio_remaining_done() called from bio_endio().
Fix this ensuring that bio_endio() is called only once for any target
BIO by always using internal clone BIOs for processing any read or
write target BIO. This allows reference counting using the target BIO
context counter to trigger the target BIO completion bio_endio() call
once all data, metadata and other zone work triggered by the BIO
complete.
Overall, this simplifies the code too as the target .end_io becomes
unnecessary and differences between read and write BIO issuing and
completion processing disappear.

commit cf66b8a0ba142fbd1bf10ac8f3ae92d1b0cb7b8f upstream.
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 63238173b2faf3d6b85a416f1c69af6c7be2413f upstream.
This reverts commit 7f3ef5dedb146e3d5063b6845781ad1bb59b92b5.
It causes new warnings [1] on shutdown when running the Google Kevin or
Scarlet (RK3399) boards under Chrome OS. Presumably our usage of DRM is
different than what Marc and Heiko test.
We're looking at a different approach (e.g., [2]) to replace this, but
IMO the revert should be taken first, as it already propagated to
-stable.

commit 04990215dec43c424daff00d1f622167b8aafd1f upstream.
vb2_start_streaming() already rolls back the buffers, so there is no
need to call __vb2_queue_cancel(). Especially since __vb2_queue_cancel()
does too much, such as zeroing the q->queued_count value, causing vb2
to think that no buffers have been queued.
It appears that this call to __vb2_queue_cancel() is a left-over from
before commit b3379c6201bb3.

commit f6c367585d0d851349d3a9e607c43e5bea993fa1 upstream.
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.

commit b704441e38f645dcfba1348ca3cc1ba43d1a9f31 upstream.
We observed some premature timeouts on a virtualization platform, the log
is like this:
case 1:
[159525.255629] mmc1: Internal clock never stabilised.
[159525.255818] mmc1: sdhci: ============ SDHCI REGISTER DUMP ===========

...
[159525.257205] mmc1: sdhci: Wake-up: 0x00000000 | Clock: 0x0000fa03
From the clock control register dump, we are pretty sure the clock was
stablized.
case 2:
[ 914.550127] mmc1: Reset 0x2 never completed.
[ 914.550321] mmc1: sdhci: ============ SDHCI REGISTER DUMP ===========
[ 914.550608] mmc1: sdhci: Sys addr: 0x00000010 | Version: 0x00001002
After checking the sdhci code, we found the timeout check actually has a
little window that the CPU can be scheduled out and when it comes back,
the original time set or check is not valid.

commit a44f7cb937321d4961bfc8f28912126b06e701c5 upstream.
When sending out CMD23 in the blk preparation, the comment there
rightfully says:
* However, it is not sufficient to just send CMD23,
* and avoid the final CMD12, as on an error condition
* CMD12 (stop) needs to be sent anyway. This, coupled
* with Auto-CMD23 enhancements provided by some
* hosts, means that the complexity of dealing
* with this is best left to the host. If CMD23 is
* supported by card and host, we'll fill sbc in and let
* the host deal with handling it correctly.
Let's do this behaviour for RPMB as well, and not send CMD23
independently. Otherwise IP cores (like Renesas SDHI) may timeout
because of automatic CMD23/CMD12 handling.

commit e8cde625bfe8a714a856e1366bcbb259d7346095 upstream.
Since v2.6.22 or so there has been reports [1] about OMAP MMC being
broken on OMAP15XX based hardware (OMAP5910 and OMAP310). The breakage
seems to have been caused by commit 46a6730e3ff9 ("mmc-omap: Fix
omap to use MMC_POWER_ON") that changed clock enabling to be done
on MMC_POWER_ON. This can happen multiple times in a row, and on 15XX
the hardware doesn't seem to like it and the MMC just stops responding.
Fix by memorizing the power mode and do the init only when necessary.
Before the patch (on Palm TE):

After the patch:

and OMAP2420 (Nokia N810).

Upstream commit 3e9efc3299dd ("i2c: aspeed: Handle master/slave combined irq events
properly") reworked the interrupt handling and fixed a warning in the process:
drivers/i2c/busses/i2c-aspeed.c: In function 'aspeed_i2c_bus_irq':
drivers/i2c/busses/i2c-aspeed.c:567:1: error: label 'out' defined but not used [-Werror=unused-label]
The warning is still present in v4.19.8 and can be fixed either by applying
that original patch, or by adding a simple #ifdef.
Here, I choose the second simpler option as the original patch seems too
invasive for a stable backport.

Commit 0eeec01488da9b1403c8c29e73eacac8af9e4bf2 upstream.
I ran into a new warning on randconfig kernels:
drivers/scsi/raid_class.c: In function 'raid_match':
drivers/scsi/raid_class.c:64:24: error: unused variable 'i' [-Werror=unused-variable]
This looks like a very old problem that for some reason was very hard to
run into, but it is very easy to fix, by replacing the incorrect #ifdef
with a simpler IS_ENABLED() check.

==================================================================
The trace happens because get_hw_stats() assumes there is room in the
memory allocated in init_cntrs() to accommodate the driver counters.
Unfortunately, that routine only allocated space for the device
counters.
Fix by insuring the allocation has room for the additional driver
counters.

Running the Clang static analyzer on IORT code detected the following
error:
Logic error: Branch condition evaluates to a garbage value
in
iort_get_platform_device_domain()
If the named component associated with a given device has no IORT
mappings, iort_get_platform_device_domain() exits its MSI mapping loop
with msi_parent pointer containing garbage, which can lead to erroneous
code path execution.
Initialize the msi_parent pointer, fixing the bug.

[ Upstream commit f6c8e432cb0479255322c5d0335b9f1699a0270c ]
nvme_stop_ctrl can be called also for reset flow and there is no need to
flush the scan_work as namespaces are not being removed. This can cause
deadlock in rdma, fc and loop drivers since nvme_stop_ctrl barriers
before controller teardown (and specifically I/O cancellation of the
scan_work itself) takes place, but the scan_work will be blocked anyways
so there is no need to flush it.
Instead, move scan_work flush to nvme_remove_namespaces() where it really
needs to flush.

This reverts commit b3cf8528bb21febb650a7ecbf080d0647be40b9f.
That commit unintentionally broke Xen balloon memory hotplug with
"hotplug_unpopulated" set to 1. As long as "System RAM" resource
got assigned under a new "Unusable memory" resource in IO/Mem tree
any attempt to online this memory would fail due to general kernel
restrictions on having "System RAM" resources as 1st level only.
The original issue that commit has tried to workaround fa564ad96366
("x86/PCI: Enable a 64bit BAR on AMD Family 15h (Models 00-1f, 30-3f,
60-7f)") also got amended by the following 03a551734 ("x86/PCI: Move

[ Upstream commit ad97d9de45835b6a0f71983b0ae0cffd7306730a ]
Driver shouldn't try to access any GFX registers until RLC is idle.
During the test, it took 12 seconds for RLC to clear the BUSY bit
in RLC_GPM_STAT register which is un-acceptable for driver.
As per RLC engineer, it would take RLC Ucode less than 10,000 GFXCLK
cycles to finish its critical section. In a lowest 300M enginer clock
setting(default from vbios), 50 us delay is enough.
This commit fix the hang when RLC introduce the work around for XGMI
which requires more cycles to setup more registers than normal

[ Upstream commit 75b7b86bdb0df37e08e44b6c1f99010967f81944 ]
Memory windows are implemented with an indirect MKey, when a page fault
event comes for a MW Mkey we need to find the MR at the end of the list of
the indirect MKeys by iterating on all items from the first to the last.
The offset calculated during this process has to be zeroed after the first
iteration or the next iteration will start from a wrong address, resulting
incorrect ODP faulting behavior.

[ Upstream commit 1830b6eeda1fed42d85f2388f79c926331a9b2d0 ]
During NVM upgrade process the host router is hot-removed for a short
while. During this time it is possible that the root port is moved into
D3cold which would be fine if the root port could trigger PME on itself.
However, many systems actually do not implement it so what happens is
that the root port goes into D3cold and never wakes up unless userspace
does PCI config space access, such as running 'lscpi'.
For this reason we explicitly prevent the root port from runtime
suspending during NVM upgrade.

[ Upstream commit 99f700366fcea1aa2fa3c49c99f371670c3c62f8 ]
We currently crash if usb_add_gadget_udc_release() fails, since the
udc->done is not initialized until in the remove function.
Furthermore, on module removal the udc data is accessed although
the release function is already triggered by usb_del_gadget_udc()
early in the function.
Fix by rewriting the release and remove functions, basically moving
all the cleanup into the release function, and doing the completion
only in the module removal case.
The patch fixes omap_udc module probe with a failing gadged, and also
allows the removal of omap_udc. Tested by running "modprobe omap_udc;
modprobe -r omap_udc" in a loop.
