The acpi_get_table() should be coupled with acpi_put_table() if
the mapped table is not used at runtime to release the table
mapping which can prevent the memory leak.
In kfd_create_crat_image_acpi(), crat_table is copied to pcrat_image,
and in kfd_create_vcrat_image_cpu(), the acpi_table is only used to
get the OEM information, so those two table mappings need to be released
after using it.

Commit 58956317c8 ("neighbor: Improve garbage collection")
guarantees neighbour table entries a five-second lifetime. Processes
which make heavy use of multicast can fill the neighour table with
multicast addresses in five seconds. At that point, neighbour entries
can't be GC-ed because they aren't five seconds old yet, the kernel
log starts to fill up with "neighbor table overflow!" messages, and
sends start to fail.
This patch allows multicast addresses to be thrown out before they've
lived out their five seconds. This makes room for non-multicast
addresses and makes messages to all addresses more reliable in these
circumstances.

RIP: 0033:0x7fb5afe588db
[CAUSE]
In try_flush_qgroup(), we assume we don't hold a transaction handle at
all. This is true for data reservation and mostly true for metadata.
Since data space reservation always happens before we start a
transaction, and for most metadata operation we reserve space in
start_transaction().
But there is an exception, btrfs_delayed_inode_reserve_metadata().
It holds a transaction handle, while still trying to reserve extra
metadata space.
When we hit EDQUOT inside btrfs_delayed_inode_reserve_metadata(), we
will join current transaction and commit, while we still have
transaction handle from qgroup code.
[FIX]
Let's check current->journal before we join the transaction.
If current->journal is unset or BTRFS_SEND_TRANS_STUB, it means
we are not holding a transaction, thus are able to join and then commit
transaction.
If current->journal is a valid transaction handle, we avoid committing
transaction and just end it
This is less effective than committing current transaction, as it won't
free metadata reserved space, but we may still free some data space
before new data writes.

When doing a buffered write, through one of the write family syscalls, we
look for ranges which currently don't have allocated extents and set the
'delalloc new' bit on them, so that we can report a correct number of used
blocks to the stat(2) syscall until delalloc is flushed and ordered extents
complete.
However there are a few other places where we can do a buffered write
against a range that is mapped to a hole (no extent allocated) and where
we do not set the 'new delalloc' bit. Those places are:
- Doing a memory mapped write against a hole;
- Cloning an inline extent into a hole starting at file offset 0;
- Calling btrfs_cont_expand() when the i_size of the file is not aligned
to the sector size and is located in a hole. For example when cloning
to a destination offset beyond EOF.
So after such cases, until the corresponding delalloc range is flushed and
the respective ordered extents complete, we can report an incorrect number
of blocks used through the stat(2) syscall.
In some cases we can end up reporting 0 used blocks to stat(2), which is a
particular bad value to report as it may mislead tools to think a file is
completely sparse when its i_size is not zero, making them skip reading
any data, an undesired consequence for tools such as archivers and other
backup tools, as reported a long time ago in the following thread (and
other past threads):
https://lists.gnu.org/archive/html/bug-tar/2016-07/msg00001.html
Example reproducer:
$ cat reproducer.sh
#!/bin/bash
MNT=/mnt/sdi
DEV=/dev/sdi
mkfs.btrfs -f $DEV > /dev/null
# mkfs.xfs -f $DEV > /dev/null
# mkfs.ext4 -F $DEV > /dev/null
# mkfs.f2fs -f $DEV > /dev/null
mount $DEV $MNT
xfs_io -f -c "truncate 64K" \
-c "mmap -w 0 64K" \
-c "mwrite -S 0xab 0 64K" \
-c "munmap" \
$MNT/foo
blocks_used=$(stat -c %b $MNT/foo)
echo "blocks used: $blocks_used"
if [ $blocks_used -eq 0 ]; then
echo "ERROR: blocks used is 0"
fi
umount $DEV
$ ./reproducer.sh
blocks used: 0
ERROR: blocks used is 0
So move the logic that decides to set the 'delalloc bit' bit into the
function btrfs_set_extent_delalloc(), since that is what we use for all
those missing cases as well as for the cases that currently work well.
This change is also preparatory work for an upcoming patch that fixes
other problems related to tracking and reporting the number of bytes used
by an inode.

If Activity Monitors (AMUs) are present, two of the counters can be used
to implement support for CPPC's (Collaborative Processor Performance
Control) delivered and reference performance monitoring functionality
using FFH (Functional Fixed Hardware).
Given that counters for a certain CPU can only be read from that CPU,
while FFH operations can be called from any CPU for any of the CPUs, use
smp_call_function_single() to provide the requested values.
Therefore, depending on the register addresses, the following values
are returned:
- 0x0 (DeliveredPerformanceCounterRegister): AMU core counter
- 0x1 (ReferencePerformanceCounterRegister): AMU constant counter
The use of Activity Monitors is hidden behind the generic
cpu_read_{corecnt,constcnt}() functions.
Read functionality for these two registers represents the only current
FFH support for CPPC. Read operations for other register values or write
operation for all registers are unsupported. Therefore, keep CPPC's FFH
unsupported if no CPUs have valid AMU frequency counters. For this
purpose, the get_cpu_with_amu_feat() is introduced.

drm: bridge: cdns: Kconfig: Switch over dependency to ARCH_K3
drm/amd/display: Add missing pflip irq
The spin_lock/unlock_irq() functions cannot be nested. The problem is
that presumably we would want the IRQs to be re-enabled on the second
call the spin_unlock_irq() but instead it will be enabled at the first
call so IRQs will be enabled earlier than expected.
In this situation the copy_resp_to_buf() function is only called from
one function and it is called with IRQs disabled. We can just use
the regular spin_lock/unlock() functions.
