Add interfaces to run calibration sequence and read out the closed
loop LRA frequency. With this change, the closed loop LRA frequency
can be read out using following commands:
echo 1 > /sys/class/qcom-haptics/lra_calibration
cat /sys/class/qcom-haptics/lra_frequency_hz
Meanwhile, correct the setting for direct play, it expects a 8-bit
value to represent the proportion of vmax instead of the actual vmax
voltage.

With the existing fscrypt IV generation methods, each file's data blocks
have contiguous DUNs. Therefore the direct I/O code "just worked"
because it only submits logically contiguous bios. But with
IV_INO_LBLK_32, the direct I/O code breaks because the DUN can wrap from
0xffffffff to 0. We can't submit bios across such boundaries.
This is especially difficult to handle when block_size != PAGE_SIZE,
since in that case the DUN can wrap in the middle of a page. Punt on
this case for now and just handle block_size == PAGE_SIZE.
Add and use a new function fscrypt_dio_supported() to check whether a
direct I/O request is unsupported due to encryption constraints.
Then, update fs/direct-io.c (used by f2fs, and by ext4 in kernel v5.4
and earlier) and fs/iomap/direct-io.c (used by ext4 in kernel v5.5 and
later) to avoid submitting I/O across a DUN discontinuity.
(This is needed in ACK now because ACK already supports direct I/O with
inline crypto. I'll be sending this upstream along with the encrypted
direct I/O support itself once its prerequisites are closer to landing.)
(cherry picked from android-mainline commit
8d6c90c9d68b985fa809626d12f8c9aff3c9dcb1)
Conflicts:
fs/ext4/file.c
fs/iomap/direct-io.c
(Dropped the iomap changes because in kernel v5.4 and earlier,
ext4 doesn't use iomap for direct I/O)
Test: For now, just manually tested direct I/O on ext4 and f2fs in the
DUN discontinuity case.

The eMMC inline crypto standard will only specify 32 DUN bits (a.k.a. IV
bits), unlike UFS's 64. IV_INO_LBLK_64 is therefore not applicable, but
an encryption format which uses one key per policy and permits the
moving of encrypted file contents (as f2fs's garbage collector requires)
is still desirable.
To support such hardware, add a new encryption format IV_INO_LBLK_32
that makes the best use of the 32 bits: the IV is set to
'SipHash-2-4(inode_number) + file_logical_block_number mod 2^32', where
the SipHash key is derived from the fscrypt master key. We hash only
the inode number and not also the block number, because we need to
maintain contiguity of DUNs to merge bios.
Unlike with IV_INO_LBLK_64, with this format IV reuse is possible; this
is unavoidable given the size of the DUN. This means this format should
only be used where the requirements of the first paragraph apply.
However, the hash spreads out the IVs in the whole usable range, and the
use of a keyed hash makes it difficult for an attacker to determine
which files use which IVs.
Besides the above differences, this flag works like IV_INO_LBLK_64 in
that on ext4 it is only allowed if the stable_inodes feature has been
enabled to prevent inode numbers and the filesystem UUID from changing.

The check for the HWO flag in dwc3_gadget_ep_reclaim_trb_sg()
causes us to break out of the loop before we call
dwc3_gadget_ep_reclaim_completed_trb(), which is what likely
should be clearing the HWO flag.
This can cause odd behavior where we never reclaim all the trbs
in the sg list, so we never call giveback on a usb req, and that
will causes transfer stalls.
This effectively resovles the adb stalls seen on HiKey960
after userland changes started only using AIO in adbd.

Prevent host suspends by capturing both bus and device votes and

Commit 2726e792a2 ("msm: kgsl: Fix linked sysfs files") thought it was
clever by reusing the callbacks for the sysfs nodes that were linked to
/sys/kernel/gpu. Unfortunately, since the /sys/kernel/gpu kobject didn't
have a device attached the callback function ended up dereferencing
nothing.
Instead, create a full kobject infrastructure with sysfs_ops and a built
in kobj to access the KGSL device. We can still use the callbacks albeit
with a wrapper to make them work from both locations. While we are in
the midst of this, make a header for the new attributes and macros so
that we can later move some of the nodes out of kgsl_pwrctrl.c with
less disruption.

commit 6803ee25f0ead1e836808acb14396bb9a9849113 upstream.
This logic is re-used for parsing a set of online CPUs. Having it as an
isolated piece of code working with input string makes it conveninent to test
this logic as well. While refactoring, also improve the robustness of original
implementation.

commit 18f02ad19e2c2a1d9e1d55a4e1c0cbf51419151c upstream.
tcp_bpf_recvmsg() invokes sk_psock_get(), which returns a reference of
the specified sk_psock object to "psock" with increased refcnt.
When tcp_bpf_recvmsg() returns, local variable "psock" becomes invalid,
so the refcount should be decreased to keep refcount balanced.
The reference counting issue happens in several exception handling paths
of tcp_bpf_recvmsg(). When those error scenarios occur such as "flags"
includes MSG_ERRQUEUE, the function forgets to decrease the refcnt
increased by sk_psock_get(), causing a refcnt leak.
Fix this issue by calling sk_psock_put() or pulling up the error queue
read handling when those error scenarios occur.

commit 0a8e7b7d08466b5fc52f8e96070acc116d82a8bb upstream.
I've noticed that when krb5i or krb5p security is in use,
retransmitted requests are missing the server's duplicate reply
cache. The computed checksum on the retransmitted request does not
match the cached checksum, resulting in the server performing the
retransmitted request again instead of returning the cached reply.
The assumptions made when removing xdr_buf_trim() were not correct.
In the send paths, the upper layer has already set the segment
lengths correctly, and shorting the buffer's content is simply a
matter of reducing buf->len.
xdr_buf_trim() is the right answer in the receive/unwrap path on
both the client and the server. The buffer segment lengths have to
be shortened one-by-one.
On the server side in particular, head.iov_len needs to be updated
correctly to enable nfsd_cache_csum() to work correctly. The simple
buf->len computation doesn't do that, and that results in
checksumming stale data in the buffer.
The problem isn't noticed until there's significant instability of
the RPC transport. At that point, the reliability of retransmit
detection on the server becomes crucial.

commit e47cb97f153193d4b41ca8d48127da14513d54c7 upstream.
The Clock Pulse Generator (CPG) device node lacks the extal2 clock.
This may lead to a failure registering the "r" clock, or to a wrong
parent for the "usb24s" clock, depending on MD_CK2 pin configuration and
boot loader CPG_USBCKCR register configuration.
This went unnoticed, as this does not affect the single upstream board
configuration, which relies on the first clock input only.
