Tomasz Duszynski 8080ccd312 iio: improve IIO_CONCENTRATION channel type description
[ Upstream commit df16c33a40 ]

IIO_CONCENTRATION together with INFO_RAW specifier is used for reporting
raw concentrations of pollutants. Raw value should be meaningless
before being properly scaled. Because of that description shouldn't
mention raw value unit whatsoever.

Fix this by rephrasing existing description so it follows conventions
used throughout IIO ABI docs.

Erik Kaneda 1e8d218655 ACPICA: Do not increment operation_region reference counts for field units
[ Upstream commit 6a54ebae6d ]

ACPICA commit e17b28cfcc31918d0db9547b6b274b09c413eb70

Object reference counts are used as a part of ACPICA's garbage
collection mechanism. This mechanism keeps track of references to
heap-allocated structures such as the ACPI operand objects.

Recent server firmware has revealed that this reference count can
overflow on large servers that declare many field units under the
same operation_region. This occurs because each field unit declaration
will add a reference count to the source operation_region.

This change solves the reference count overflow for operation_regions
objects by preventing fieldunits from incrementing their
operation_region's reference count. Each operation_region's reference
count will not be changed by named objects declared under the Field
operator. During namespace deletion, the operation_region namespace
node will be deleted and each fieldunit will be deleted without
touching the deleted operation_region object.

Coly Li ca6654d7da bcache: fix super block seq numbers comparision in register_cache_set()
[ Upstream commit 117f636ea6 ]

In register_cache_set(), c is pointer to struct cache_set, and ca is
pointer to struct cache, if ca->sb.seq > c->sb.seq, it means this
registering cache has up to date version and other members, the in-
memory version and other members should be updated to the newer value.

But current implementation makes a cache set only has a single cache
device, so the above assumption works well except for a special case.
The execption is when a cache device new created and both ca->sb.seq and
c->sb.seq are 0, because the super block is never flushed out yet. In
the location for the following if() check,
2156         if (ca->sb.seq > c->sb.seq) {
2157                 c->sb.version           = ca->sb.version;
2158                 memcpy(c->sb.set_uuid, ca->sb.set_uuid, 16);
2159                 c->sb.flags             = ca->sb.flags;
2160                 c->sb.seq               = ca->sb.seq;
2161                 pr_debug("set version = %llu\n", c->sb.version);
2162         }
c->sb.version is not initialized yet and valued 0. When ca->sb.seq is 0,
the if() check will fail (because both values are 0), and the cache set
version, set_uuid, flags and seq won't be updated.

The above problem is hiden for current code, because the bucket size is
compatible among different super block version. And the next time when
running cache set again, ca->sb.seq will be larger than 0 and cache set
super block version will be updated properly.

But if the large bucket feature is enabled,  sb->bucket_size is the low
16bits of the bucket size. For a power of 2 value, when the actual
bucket size exceeds 16bit width, sb->bucket_size will always be 0. Then
read_super_common() will fail because the if() check to
is_power_of_2(sb->bucket_size) is false. This is how the long time
hidden bug is triggered.

This patch modifies the if() check to the following way,
2156         if (ca->sb.seq > c->sb.seq || c->sb.seq == 0) {
Then cache set's version, set_uuid, flags and seq will always be updated
corectly including for a new created cache device.

Jim Cromie db9b14ae4b dyndbg: fix a BUG_ON in ddebug_describe_flags

ddebug_describe_flags() currently fills a caller provided string buffer,
after testing its size (also passed) in a BUG_ON.  Fix this by
replacing them with a known-big-enough string buffer wrapped in a
struct, and passing that instead.

Also simplify ddebug_describe_flags() flags parameter from a struct to
a member in that struct, and hoist the member deref up to the caller.
This makes the function reusable (soon) where flags are unpacked.

Adding a suspend hook to the BDC driver that halts the controller before
S2 entry thus preventing unwanted access to the BDC register space during

Check the return value of pcie_capability_read_dword() to ensure success.

When USB or SDIO device got abnormal bus disconnection, host driver
tried to clean up the skbs in PSQ and TXQ (The skb's pointer in hanger
slot linked to PSQ and TSQ), so we should set the state of skb hanger slot
to BRCMF_FWS_HANGER_ITEM_STATE_FREE before freeing skb.
In brcmf_fws_bus_txq_cleanup it already sets
BRCMF_FWS_HANGER_ITEM_STATE_FREE before freeing skb, therefore we add the
same thing in brcmf_fws_psq_flush to avoid following warning message.

Wright Feng 29dd5e5309 brcmfmac: keep SDIO watchdog running when console_interval is non-zero
[ Upstream commit eccbf46b15 ]

brcmfmac host driver makes SDIO bus sleep and stops SDIO watchdog if no
pending event or data. As a result, host driver does not poll firmware
console buffer before buffer overflow, which leads to missing firmware
logs. We should not stop SDIO watchdog if console_interval is non-zero
in debug build.

inactive_list. Fix this by making sure that the initialization is complete
before moving the msm_obj object to the inactive list.

On targets where GMU is available, GMU takes over the ownership of GX GDSC
during its initialization. So, move the refcount-get on GX PD before we
initialize the GMU. This ensures that nobody can collapse the GX GDSC
once GMU owns the GX GDSC. This patch fixes some GMU OOB errors seen
during GPU wake up during a system resume.

This is because we're holding the block_group->lock while trying to dump
the free space cache.  However we don't need this lock, we just need it
to read the values for the printk, so move the free space cache dumping
outside of the block group lock.

Masahiro Yamada 7795eb18ce mmc: sdhci-cadence: do not use hardware tuning for SD mode
[ Upstream commit adc40a5179 ]

As commit ef6b75671b ("mmc: sdhci-cadence: send tune request twice to
work around errata") stated, this IP has an errata. This commit applies
the second workaround for the SD mode.

Due to the errata, it is not possible to use the hardware tuning provided
by SDHCI_HOST_CONTROL2.

Use the software-controlled tuning like the eMMC mode.

Set sdhci_host_ops::platform_execute_tuning instead of overriding
mmc_host_ops::execute_tuning.

[ Upstream commit fb2420b701 ]

While we expose the ability to turn off hardware dithering for nouveau,
we actually make the mistake of turning it on anyway, due to
dithering_depth containing a non-zero value if our dithering depth isn't
also set to 6 bpc.

So, fix it by never enabling dithering when it's disabled.

Evgeny Novikov 6754d2a86c video: fbdev: neofb: fix memory leak in neo_scan_monitor()
[ Upstream commit edcb3895a7 ]

neofb_probe() calls neo_scan_monitor() that can successfully allocate a
memory for info->monspecs.modedb and proceed to case 0x03. There it does
not free the memory and returns -1. neofb_probe() goes to label
err_scan_monitor, thus, it does not free this memory through calling
fb_destroy_modedb() as well. We can not go to label err_init_hw since
neo_scan_monitor() can fail during memory allocation. So, the patch frees
the memory directly for case 0x03.

Sedat Dilek 8b8d17d9ff crypto: aesni - Fix build with LLVM_IAS=1

When building with LLVM_IAS=1 means using Clang's Integrated Assembly (IAS)
from LLVM/Clang >= v10.0.1-rc1+ instead of GNU/as from GNU/binutils
I see the following breakage in Debian/testing AMD64:

Craig Topper suggested me in ClangBuiltLinux issue #1050:

> I think the "too many positional arguments" is because the parser isn't able
> to handle the trailing commas.
>
> The "unknown use of instruction mnemonic" is because the macro was named
> GHASH_4_ENCRYPT_4_PARALLEL_DEC but its being instantiated with
> GHASH_4_ENCRYPT_4_PARALLEL_dec I guess gas ignores case on the
> macro instantiation, but llvm doesn't.

First, I removed the trailing comma in the PRECOMPUTE line.

Second, I substituted:
1. GHASH_4_ENCRYPT_4_PARALLEL_DEC -> GHASH_4_ENCRYPT_4_PARALLEL_dec
2. GHASH_4_ENCRYPT_4_PARALLEL_ENC -> GHASH_4_ENCRYPT_4_PARALLEL_enc

With these changes I was able to build with LLVM_IAS=1 and boot on bare metal.

I confirmed that this works with Linux-kernel v5.7.5 final.

NOTE: This patch is on top of Linux v5.7 final.

Thanks to Craig and especially Nick for double-checking and his comments.
