btrfs_free_reserved_bytes uses the variable "ret" for return value,
but it is not modified after initialzation. Further, I find that any of
the callers do not handle the return value, so it is safe to drop the
unneeded "ret" and return void. There are no callees that would need the
function to handle or pass the value either.

[BUG]
In the following case, rescan won't zero out the number of qgroup 1/0:
$ mkfs.btrfs -fq $DEV
$ mount $DEV /mnt
$ btrfs quota enable /mnt
$ btrfs qgroup create 1/0 /mnt
$ btrfs sub create /mnt/sub
$ btrfs qgroup assign 0/257 1/0 /mnt
$ dd if=/dev/urandom of=/mnt/sub/file bs=1k count=1000
$ btrfs sub snap /mnt/sub /mnt/snap
$ btrfs quota rescan -w /mnt
$ btrfs qgroup show -pcre /mnt

^^^^^^^^^^ ^^^^^^^^ not cleared
[CAUSE]
Before rescan we call qgroup_rescan_zero_tracking() to zero out all
qgroups' accounting numbers.
However we don't mark all qgroups dirty, but rely on rescan to do so.
If we have any high level qgroup without children, it won't be marked
dirty during rescan, since we cannot reach that qgroup.
This will cause QGROUP_INFO items of childless qgroups never get updated
in the quota tree, thus their numbers will stay the same in "btrfs
qgroup show" output.
[FIX]
Just mark all qgroups dirty in qgroup_rescan_zero_tracking(), so even if
we have childless qgroups, their QGROUP_INFO items will still get
updated during rescan.

When the replace is running the fs_devices::num_devices also includes
the replaced device, however in some operations like device delete and
balance it needs the actual num_devices without the repalced devices.
The function btrfs_num_devices() just provides that.
And here is a scenario how balance and repalce items could co-exist:
Consider balance is started and paused, now start the replace followed
by a unmount or system power-cycle. During following mount, the
open_ctree() first restarts the balance so it must check for the device
replace otherwise our num_devices calculation will be wrong.

There are two members in struct btrfs_root which indicate root's
objectid: objectid and root_key.objectid.
They are both set to the same value in __setup_root():
static void __setup_root(struct btrfs_root *root,
struct btrfs_fs_info *fs_info,
u64 objectid)
{
...
root->objectid = objectid;
...
root->root_key.objectid = objecitd;
...
}
and not changed to other value after initialization.
grep in btrfs directory shows both are used in many places:
$ grep -rI "root->root_key.objectid" | wc -l
133
$ grep -rI "root->objectid" | wc -l
55
(4.17, inc. some noise)
It is confusing to have two similar variable names and it seems
that there is no rule about which should be used in a certain case.
Since ->root_key itself is needed for tree reloc tree, let's remove
'objecitd' member and unify code to use ->root_key.objectid in all places.

Commit b9762bebc633 ("gpiolib: Pass bitmaps, not integer arrays, to
get/set array") changed the way GPIO values are passed to
gpiod_get/set_array_value() and friends. The new code introduced into
mmc_pwrseq_simple_set_gpios_value() incorrectly interpretes the 'value'
argument as a bitmap of GPIO values and assigns it directly to the
'values' bitmap variable passed to gpiod_set_array_value_cansleep()
instead of filling that bitmap with bits equal to the 'value' argument.
As a result, only member 0 of the array is handled correctly.
Moreover, wrong assumption is taken about the 'values' bitmap size not
exceding the number of bits of the 'value' argument type.
Fix it.

The Mediatek's host controller has two slots, each with its own control
registers. The host driver needs to identify what slot is connected to
what port in order to access the device's configuration space.
Current code retrieving slot connected to a given endpoint device.
Assuming each slot is connected to one endpoint device as below:
host bridge
bus 0 --> __________|_______
| |
| |
slot 0 slot 1
bus 1 -->| bus 2 --> |
| |
EP 0 EP 1
During PCI enumeration, system software will scan all the PCI devices on
every bus starting from devfn 0. Using PCI_SLOT(devfn) for matching an
endpoint to its slot is erroneous in that the devfn does not contain the
hierarchical bus numbering in it. In order to match an endpoint with its
slot (and related port), the PCI tree must be walked up to the root bus
(where the root ports are situated) and then the PCI_SLOT(devfn)
matching logic can be correctly applied for matching.
This patch fixes the mtk_pcie_find_port() slot matching logic by adding
appropriate PCI tree walking code to retrieve the slot/port a given
endpoint is connected to.

The recent patch to fix the afs_server struct leak didn't actually fix the
bug, but rather fixed some of the symptoms. The problem is that an
asynchronous call that holds a resource pointed to by call->reply[0] will
find the pointer cleared in the call destructor, thereby preventing the
resource from being cleaned up.
In the case of the server record leak, the afs_fs_get_capabilities()
function in devel code sets up a call with reply[0] pointing at the server
record that should be altered when the result is obtained, but this was
being cleared before the destructor was called, so the put in the
destructor does nothing and the record is leaked.
Commit f014ffb025c1 removed the additional ref obtained by
afs_install_server(), but the removal of this ref is actually used by the
garbage collector to mark a server record as being defunct after the record
has expired through lack of use.
The offending clearance of call->reply[0] upon completion in
afs_process_async_call() has been there from the origin of the code, but
none of the asynchronous calls actually use that pointer currently, so it
should be safe to remove (note that synchronous calls don't involve this
function).
Fix this by the following means:
(1) Revert commit f014ffb025c1.
(2) Remove the clearance of reply[0] from afs_process_async_call().
Without this, afs_manage_servers() will suffer an assertion failure if it
sees a server record that didn't get used because the usage count is not 1.

host->chan_{rx,tx} represents the DMA capability of the platform.
Even if DMA is supported, there are cases where we want to use PIO,
for example, data length is short enough as commit 5f52c3552946
("mmc: tmio: use PIO for short transfers") mentioned.
Regarding the hardware control flow, we are interested in whether DMA
is currently enabled or not, instead of whether the platform has the
DMA capability.
Hence, the several conditionals in tmio_mmc_core.c end up with
checking host->chan_{rx,tx} and !host->force_pio. This is not nice.
Let's flip the flag host->force_pio into host->dma_on.
host->dma_on represents whether the DMA is currently enabled or not.
This flag is set false in the beginning of each command, then should
be set true by tmio_mmc_start_dma() when the DMA is turned on.

TMIO_MMC_HAVE_HIGH_REG is confusing due to its counter-intuitive name.
All the TMIO MMC variants (TMIO MMC, Renesas SDHI, UniPhier SD) actually
have high registers. It is just that each of them implements its own
registers there. The original IP from Panasonic only defines registers
0x00-0xff in the bus_shift=1 review. The register area above them is
platform-dependent.
In fact, TMIO_MMC_HAVE_HIGH_REG is set only by tmio-mmc.c and used to
test the accessibility of CTL_SDIO_REGS. Because it is specific to
the TMIO MFD variant, the right thing to do is to move such registers
to tmio_mmc.c and delete the TMIO_MMC_HAVE_HIGH_REG flag.

With the new multi zcrypt device node support there came
in a code rework which broke the in-kernel api function
zcrypt_send_cprb(). This function is used by the pkey kernel
module and as an effect, transforming a secure key into a
protected key did not work any more.

Since the core regulator code is treating GPIO descriptors as
nonexclusive, i.e. it assumes that the enable GPIO line may be
shared with several regulators, let's add the flag introduced
for fixing this problem on fixed regulators to all drivers
fetching GPIO descriptors to avoid possible regressions.

In some environments it is common that many hosts share the same lower half
of their IPv6 addresses (in particular ::1). As __xfrm6_addr_hash() and
__xfrm6_daddr_saddr_hash() calculate the hash only from the lower halves,
as much as 1/3 of the hosts ends up in one hashtable chain which harms the
performance.
Use complete IPv6 addresses when calculating the hashes. Rather than just
adding two more words to the xor, use jhash2() for consistency with
__xfrm6_pref_hash() and __xfrm6_dpref_spref_hash().

If we did some signal processing, we have to reload the pt_regs
tstate register because it's value may have changed.
In doing so we also have to extract the %pil value contained in there
anre load that into %l4.
This value is at bit 20 and thus needs to be shifted down before we
later write it into the %pil register.
Most of the time this is harmless as we are returning to userspace
and the %pil is zero for that case.

So that when it is unset, ie. '-1', userspace can see it
properly.
