The ACPI buffer memory (buffer.pointer) should be freed as the
buffer is not used after acpi_evaluate_object(), free it to
prevent memory leak.

In the blamed commit, a rudimentary reallocation procedure for RX buffer
descriptors was implemented, for the situation when their format changes
between normal (no PTP) and extended (PTP).
enetc_hwtstamp_set() calls enetc_close() and enetc_open() in a sequence,
and this sequence loses information which was previously configured in
the TX BDR Mode Register, specifically via the enetc_set_bdr_prio() call.
The TX ring priority is configured by tc-mqprio and tc-taprio, and
affects important things for TSN such as the TX time of packets. The
issue manifests itself most visibly by the fact that isochron --txtime
reports premature packet transmissions when PTP is first enabled on an
enetc interface.
Save the TX ring priority in a new field in struct enetc_bdr (occupies a
2 byte hole on arm64) in order to make this survive a ring reconfiguration.

The transaction buffer is allocated by using the size of the packet buf,
and subtracting two which seems intended to remove the two tags which are
not present in the target structure. This calculation leads to under
counting memory because of differences between the packet contents and the
target structure. The aid_len field is a u8 in the packet, but a u32 in
the structure, resulting in at least 3 bytes always being under counted.
Further, the aid data is a variable length field in the packet, but fixed
in the structure, so if this field is less than the max, the difference is
added to the under counting.
To fix, perform validation checks progressively to safely reach the
next field, to determine the size of both buffers and verify both tags.
Once all validation checks pass, allocate the buffer and copy the data.
This eliminates freeing memory on the error path, as validation checks are
moved ahead of memory allocation.

The first validation check for EVT_TRANSACTION has two different checks
tied together with logical AND. One is a check for minimum packet length,
and the other is for a valid aid_tag. If either condition is true (fails),
then an error should be triggered. The fix is to change && to ||.

Either ublk_can_use_task_work() is true or not, io commands are
forwarded to ublk server in reverse order, since llist_add() is
always to add one element to the head of the list.
Even though block layer doesn't guarantee request dispatch order,
requests should be sent to hardware in the sequence order generated
from io scheduler, which usually considers the request's LBA, and
order is often important for HDD.
So forward io commands in the sequence made from io scheduler by
aligning task work with current io_uring command's batch handling,
and it has been observed that both can get similar performance data
if IORING_SETUP_COOP_TASKRUN is set from ublk server.

For DASD devices in raw_track_access mode only full track images are
read and written.
For this purpose it is not necessary to do search operation in the
locate record extended function. The documentation even states that
this might fail if the searched record is not found on a track.
Currently the driver sets a value of 1 in the search field for the first
record after record zero. This is the default for disks not in
raw_track_access mode but record 1 might be missing on a completely
empty track.
There has not been any problem with this on IBM storage servers but it
might lead to errors with DASD devices on other vendors storage servers.
Fix this by setting the search field to 0. Record zero is always available
even on a completely empty track.

There's been a very long running bug that seems to have been neglected for

After digging through amd's rather creative method for accessing registers,
I eventually discovered the problem likely has to do with the fact that on
my dce120 GPU there are supposedly 7 sets of audio registers. But we only
define a register mapping for 6 sets.
So, fix this and fix the KASAN warning finally.

Sanity checks were added to verify the v4l2_bt_timings blanking fields
in order to avoid integer overflows when userspace passes weird values.
But that assumed that userspace would correctly fill in the front porch,
backporch and sync values, but sometimes all you know is the total
blanking, which is then assigned to just one of these fields.
And that can fail with these checks.
So instead set a maximum for the total horizontal and vertical
blanking and check that each field remains below that.
That is still sufficient to avoid integer overflows, but it also
allows for more flexibility in how userspace fills in these fields.

In mtk_ppe_init(), when dmam_alloc_coherent() or devm_kzalloc() failed,
the rhashtable ppe->l2_flows isn't destroyed. Fix it.
In mtk_probe(), when mtk_ppe_init() or mtk_eth_offload_init() or
register_netdev() failed, have the same problem. Fix it.

When fail to dma_map_single() in mtk_rx_alloc(), it returns directly.
But the memory allocated for local variable data is not freed, and
local variabel data has not been attached to ring->data[i] yet, so the
memory allocated for local variable data will not be freed outside
mtk_rx_alloc() too. Thus memory leak would occur in this scenario.
Add skb_free_frag(data) when dma_map_single() failed.

The three UFS reference clocks, gcc_ufs_ref_clkref_clk for external
UFS devices, gcc_ufs_card_clkref_clk and gcc_ufs_1_card_clkref_clk for
two PHYs are all sourced from CXO.
Added parent_data for all three reference clocks described above to
reflect that all three clocks are sourced from CXO to have valid
frequency for the ref clock needed by UFS controller driver.

We face some regressions on a few IXP42x systems when
accessing flash, the following unrelated error prints
appear from the PCI driver:
ixp4xx-pci c0000000.pci: PCI: abort_handler addr = 0xff9ffb5f,
isr = 0x0, status = 0x22a0
ixp4xx-pci c0000000.pci: imprecise abort
(...)
It turns out that while bit 7 is masked "reserved" it is
not unused, so masking it off as zero is dangerous, and
breaks flash access on some systems such as the NSLU2.
Be more careful and avoid masking off any of the reserved
bits 7, 8, 9 or 30. Only keep masking EXP_WORD (bit 2)
on IXP43x which is necessary in some setups.

If the system is restarted via kexec(), the peripherals do not start
with a known state.
If the previous system had enabled an IRQs we will receive unexected
IRQs that can lock the system.

When the amd_pstate driver is built-in users still need a method to be
able enable or disable it depending upon their circumstance.
Add support for an early parameter to do this.
There is some performance degradation on a number of ASICs in the
passive mode. This performance issue was originally discovered in
shared memory systems but it has been proven that certain workloads
on MSR systems also suffer performance issues.
Set the amd-pstate driver as disabled by default to temporarily
mitigate the performance problem.
1) with `amd_pstate=disable`, pstate driver will be disabled to load at
kernel booting.
2) with `amd_pstate=passive`, pstate driver will be enabled and loaded
as non-autonomous working mode supported in the low-level power
management firmware.
3) If neither parameter is specified, the driver will be disabled by
default to avoid triggering performance regressions in certain ASICs

Currently when the amd-pstate and acpi_cpufreq are both built into
kernel as module driver, amd-pstate will not be loaded by default
in this case.
Change amd-pstate driver as built-in type, it will resolve the loading
sequence problem to allow user to make amd-pstate driver as the default
cpufreq scaling driver.

init
MSR_AMD_PERF_CTL is guaranteed to be 0 on a cold boot. However, on a
kexec boot, for instance, it may have a non-zero value (if the cpu was
in a non-P0 Pstate). In such cases, the cores with non-P0 Pstates at
boot will never be pushed to P0, let alone boost frequencies.
Kexec is a common workflow for reboot on Linux and this creates a
regression in performance. Fix it by explicitly setting the
MSR_AMD_PERF_CTL to 0 during amd_pstate driver init.
