net: ipa: move configuration data files
This series moves the "ipa_data-vX.Y.c" files into a subdirectory.
The first patch adds a Makefile variable containing the list of
supported IPA versions, and uses it to simplify the way these files
are specified.

Create a variable in the Makefile listing the IPA versions supported
by the driver. Use that to create the list of configuration data
object files used (rather than listing them all individually).

net: ipa: small transaction updates
Version 2 of this series corrects a misspelling of "outstanding"
pointed out by the netdev test bots. (For some reason I don't see
that when I run "checkpatch".) I found and fixed a second instance
of that word being misspelled as well.
This series includes three changes to the transaction code. The
first adds a new transaction list that represents a distinct state
that has not been maintained. The second moves a field in the
transaction information structure, and reorders its initialization
a bit. The third skips a function call when it is known not to be
necessary.
The last two are very small "leftover" patches.

In gsi_trans_free(), there's no point in ipa_gsi_trans_release() if
a transaction is unused. No used TREs means no IPA layer resources
to clean up. So only call ipa_gsi_trans_release() if at least one
TRE was used.

The transaction map is really associated with the transaction pool;
move its definition earlier in the gsi_trans_info structure.
Rearrange initialization in gsi_channel_trans_init() so it
sets the tre_avail value first, then initializes the transaction
pool, and finally allocating the transaction map.

We currently put a transaction on the pending list when it has
been committed. But until the channel's doorbell rings, these
transactions aren't actually "owned" by the hardware yet.
Add a new "committed" state (and list), to represent transactions
that have been committed but not yet sent to hardware. Define
"pending" to mean committed transactions that have been sent
to hardware but have not yet completed.

Create a new attribute group meant to provide a single place that
defines endpoint IDs that might be needed by user space. Not all
defined endpoints are presented, and only those that are defined
will be made visible.
The new attributes use "extended" device attributes to hold endpoint
IDs, which is a little more compact and efficient. Reimplement the
existing modem endpoint ID attribute files using common code.

This patch fixes a build error reported in the link. [0]

dpu_encoder_helper_phys_cleanup() was not populating neither
wb or intf to the intf_cfg before calling the reset_intf_cfg().
This causes the reset of the active bits of wb/intf to be
skipped which is incorrect.
Fix this by populating the relevant wb or intf indices correctly.

I observed the following evidence of a memory leak while running xfs/399

This newly-added assertion checks that there aren't any incore data
structures hanging off the incore fork when we're trying to reset its
contents. From the call trace, it is evident that iget was trying to
construct an incore inode from the ondisk inode, but the attr fork
verifier failed and we were trying to undo all the memory allocations
that we had done earlier.
The three assertions in xfs_ifork_zap_attr check that the caller has
already called xfs_idestroy_fork, which clearly has not been done here.
As the zap function then zeroes the pointers, we've effectively leaked
the memory.
The shortest change would have been to insert an extra call to
xfs_idestroy_fork, but it makes more sense to bundle the _idestroy_fork
call into _zap_attr, since all other callsites call _idestroy_fork
immediately prior to calling _zap_attr. IOWs, it eliminates one way to
fail.
Note: This change only applies cleanly to 2ed5b09b3e8f, since we just
reworked the attr fork lifetime. However, I think this memory leak has
existed since 0f45a1b20cd8, since the chain xfs_iformat_attr_fork ->
xfs_iformat_local -> xfs_init_local_fork will allocate
ifp->if_u1.if_data, but if xfs_ifork_verify_local_attr fails,
xfs_iformat_attr_fork will free i_afp without freeing any of the stuff
hanging off i_afp. The solution for older kernels I think is to add the
missing call to xfs_idestroy_fork just prior to calling kmem_cache_free.
Found by fuzzing a.sfattr.hdr.totsize = lastbit in xfs/399.

Darrick and Sachin Sant reported that xfs/435 and xfs/436 would
report an non-empty xfs_buf slab on module remove. This isn't easily
to reproduce, but is clearly a side effect of converting the buffer
caceh to RUC freeing and lockless lookups. Sachin bisected and
Darrick hit it when testing the patchset directly.
Turns out that the xfs_buf slab is not destroyed when all the other
XFS slab caches are destroyed. Instead, it's got it's own little
wrapper function that gets called separately, and so it doesn't have
an rcu_barrier() call in it that is needed to drain all the rcu
callbacks before the slab is destroyed.
Fix it by removing the xfs_buf_init/terminate wrappers that just
allocate and destroy the xfs_buf slab, and move them to the same
place that all the other slab caches are set up and destroyed.

The 'ctime', 'mtime', and 'atime' for inode is the type of
'xfs_timestamp_t', which is a 64-bit type:
/* fs/xfs/libxfs/xfs_format.h begin */
typedef __be64 xfs_timestamp_t;
/* fs/xfs/libxfs/xfs_format.h end */
When the 'bigtime' feature is disabled, this 64-bit type is splitted
into two parts of 32-bit, one part is encoded for seconds since
1970-01-01 00:00:00 UTC, the other part is encoded for nanoseconds
above the seconds, this two parts are the type of
'xfs_legacy_timestamp' and the min and max time value of this type are
defined as macros 'XFS_LEGACY_TIME_MIN' and 'XFS_LEGACY_TIME_MAX':
/* fs/xfs/libxfs/xfs_format.h begin */
struct xfs_legacy_timestamp {
__be32 t_sec; /* timestamp seconds */
__be32 t_nsec; /* timestamp nanoseconds */
};
#define XFS_LEGACY_TIME_MIN ((int64_t)S32_MIN)
#define XFS_LEGACY_TIME_MAX ((int64_t)S32_MAX)
/* fs/xfs/libxfs/xfs_format.h end */
/* include/linux/limits.h begin */
#define U32_MAX ((u32)~0U)
#define S32_MAX ((s32)(U32_MAX >> 1))
#define S32_MIN ((s32)(-S32_MAX - 1))
/* include/linux/limits.h end */
'XFS_LEGACY_TIME_MIN' is the min time value of the
'xfs_legacy_timestamp', that is -(2^31) seconds relative to the
1970-01-01 00:00:00 UTC, it can be converted to human-friendly time
value by 'date' command:
/* command begin */
[root@~]# date --utc -d '@0' +'%Y-%m-%d %H:%M:%S'
1970-01-01 00:00:00
[root@~]# date --utc -d "@`echo '-(2^31)'|bc`" +'%Y-%m-%d %H:%M:%S'
1901-12-13 20:45:52
[root@~]#
/* command end */
When 'bigtime' feature is enabled, this 64-bit type becomes a 64-bit
nanoseconds counter, with the start time value is the min time value of
'xfs_legacy_timestamp'(start time means the value of 64-bit nanoseconds
counter is 0). We have already caculated the min time value of
'xfs_legacy_timestamp', that is 1901-12-13 20:45:52 UTC, but the comment
for the start time value of inode with 'bigtime' feature enabled writes
the value is 1901-12-31 20:45:52 UTC:
/* fs/xfs/libxfs/xfs_format.h begin */
/*
* XFS Timestamps
* ==============
* When the bigtime feature is enabled, ondisk inode timestamps become an
* unsigned 64-bit nanoseconds counter. This means that the bigtime inode
* timestamp epoch is the start of the classic timestamp range, which is
* Dec 31 20:45:52 UTC 1901. ...
...
*/
/* fs/xfs/libxfs/xfs_format.h end */
That is a typo, and this patch corrects the typo, from 'Dec 31' to
'Dec 13'.

kmap() is being deprecated in favor of kmap_local_page().
Two main problems with kmap(): (1) It comes with an overhead as mapping
space is restricted and protected by a global lock for synchronization and
(2) it also requires global TLB invalidation when the kmap’s pool wraps
and it might block when the mapping space is fully utilized until a slot
becomes available.
With kmap_local_page() the mappings are per thread, CPU local, can take
page faults, and can be called from any context (including interrupts).
Tasks can be preempted and, when scheduled to run again, the kernel
virtual addresses are restored and still valid.
kmap_local_page() is faster than kmap() in kernels with HIGHMEM enabled.
Since the use of kmap_local_page() in module_gzip_decompress() and in
module_xz_decompress() is safe (i.e., it does not break the strict rules
of use), it should be preferred over kmap().
Therefore, replace kmap() with kmap_local_page().
Tested on a QEMU/KVM x86_32 VM with 4GB RAM, booting kernels with
HIGHMEM64GB enabled. Modules compressed with XZ or GZIP decompress
properly.

A few weeks ago, QEMU switched docs/specs/fw_cfg.txt to be
docs/specs/fw_cfg.rst, so update the reference in the kernel docs to
reflect this. Also add a link to the online documentation to make it
easier to find.

Using obj-$() := instead of obj-$() += leads to the latter assignment
overwriting earlier value. Fix this by using incremental assignment to
add additional objects to build.

Protect the struct amdgpu_bo_list with a mutex. This is used during command
submission in order to avoid buffer object corruption as recorded in
the link below.
v2 (chk): Keep the mutex looked for the whole CS to avoid using the
list from multiple CS threads at the same time.

Commit 5bfcbd22ee4e ("apparmor: Enable tuning of policy paranoid load for
embedded systems") introduces the config SECURITY_APPARMOR_PARANOID_LOAD,
but then refers in the code to SECURITY_PARANOID_LOAD; note the missing
APPARMOR in the middle.
Correct this to the introduced and intended config option.

[Why]
The amdgpu_dm file contains most of the code that works as an interface
between DRM API and DC. As a result, this file becomes very large since
it comprises multiple abstractions such as plane manipulation.
[How]
This commit extracts the plane code to its specific file named
amdgpu_dm_plane. This change does not change anything inside the
functions; the only exception is converting some static functions to a
global function.

[Why & How]
In order to leverage igt tool to maintain mst feature, expose new
debugfs entry "mst_progress_status".
In our dm flow, record down the result of each phase of mst and user
can examine the mst result by checking whether each phase get completed
successfully.

[Why & How]
Add "is_mst_connector" debugfs entry to help distinguish whether
a connector is in a mst topology or not.
Access it with the following command:
cat /sys/kernel/debug/dri/0/DP-X/is_mst_connector
Result:
- "root" stands for the root connector of the topology
- "branch" stands for branch device of the topology
- "end" stands for leaf node connector of the topology
- "no" stands for the connector is not a device of a mst topology

[Why & How]
Correct few problems below to have debugfs trigger_hotplug entry
supports mst case
* Adjust the place for acquiring the hpd_lock. We'll also access
dc_link when simulate unplug
* When detect the connector is a mst root, call
reset_cur_dp_mst_topology() to simulate unplug
* Don't support hotplug caused by CSN message since we can't change
mst topology info directly. We can't simulate that
* Clean up redundant code

[Why]
When CONFIG_DRM_AMD_SECURE_DISPLAY is enabled, it will try
to register vertical interrupt 0 for specific task.
Currently, only dcn10 have defined relevant info for vertical interrupt
0. If we enable CONFIG_DRM_AMD_SECURE_DISPLAY for other dcn ASIC, will
get DC_IRQ_SOURCE_INVALID while calling dc_interrupt_to_irq_source() and
cause pointer errors.
[How]
Add support of vertical interrupt 0 for all dcn ASIC.

TTM used to track the "acc_size" of all BOs internally. We needed to
keep track of it in our memory reservation to avoid TTM running out
of memory in its own accounting. However, that "acc_size" accounting
has since been removed from TTM. Therefore we don't really need to
track it any more.
