[ Upstream commit 376a8c2a14 ]
The PMF driver allocates a shared memory buffer using
tee_shm_alloc_kernel_buf() for communication with the PMF-TA.
The latest PMF-TA version introduces new structures with OEM debug
information and additional policy input conditions for evaluating the
policy binary. Consequently, the shared memory size must be increased to
ensure compatibility between the PMF driver and the updated PMF-TA.
To do so, introduce the new PMF-TA UUID and update the PMF shared memory
configuration to ensure compatibility with the latest PMF-TA version.
Additionally, export the TA UUID.
These updates will result in modifications to the prototypes of
amd_pmf_tee_init() and amd_pmf_ta_open_session().

Avoid by doing idr_alloc() on a NULL pointer to register the id, and

Also making sure to not set struct pmu members after publishing
the struct pmu, duh.
[ introduce idr_cmpxchg() in order to better handle the idr_replace()

already have replaced the value and there is no going back. ]

[ Upstream commit 011ea742a2 ]
If a data sector on an OFS floppy contains a value > 0x1e8 (the
largest amount of data that fits in the sector after its header), then
an Amiga reading the file can return corrupt data, by taking the
overlarge size at its word and reading past the end of the buffer it
read the disk sector into!
The cause: when affs_write_end_ofs() writes data to an OFS filesystem,
the new size field for a data block was computed by adding the amount
of data currently being written (into the block) to the existing value
of the size field. This is correct if you're extending the file at the
end, but if you seek backwards in the file and overwrite _existing_
data, it can lead to the size field being larger than the maximum
legal value.
This commit changes the calculation so that it sets the size field to
the max of its previous size and the position within the block that we
just wrote up to.

[ Upstream commit e4cf8ec4de ]
If I write a file to an OFS floppy image, and try to read it back on
an emulated Amiga running Workbench 1.3, the Amiga reports a disk
error trying to read the file. (That is, it's unable to read it _at
all_, even to copy it to the NIL: device. It isn't a matter of getting
the wrong data and being unable to parse the file format.)
This is because the 'sequence number' field in the OFS data block
header is supposed to be based at 1, but affs writes it based at 0.
All three locations changed by this patch were setting the sequence
number to a variable 'bidx' which was previously obtained by dividing
a file position by bsize, so bidx will naturally use 0 for the first
block. Therefore all three should add 1 to that value before writing
it into the sequence number field.
With this change, the Amiga successfully reads the file.

The firmware dumps can be pretty big, and since we use single
pages for each SG table entry, even the table itself may end
up being an order-5 allocation. Build chained tables so that
we need not allocate a higher-order table here.
This could be improved and cleaned up, e.g. by using the SG
pool code or simply kvmalloc(), but all of that would require
also updating the devcoredump first since that frees it all,
so we need to be more careful. SG pool might also run against
the CONFIG_ARCH_NO_SG_CHAIN limitation, which is irrelevant
here.
Also use _devcd_free_sgtable() for the error paths now, much
simpler especially since it's in two places now.

[ Upstream commit 9e9b893404 ]
Prior to commit 496121c021 ("ACPI: processor: idle: Allow probing on
platforms with one ACPI C-state"), the acpi_idle driver wouldn't load on
systems without a valid C-State at least as deep as C2.
The behavior was desirable for guests on hypervisors such as VMWare
ESXi, which by default don't have the _CST ACPI method, and set the C2
and C3 latencies to 101 and 1001 microseconds respectively via the FADT,
to signify they're unsupported.
Since the above change though, these virtualized deployments end up
loading acpi_idle, and thus entering the default C1 C-State set by
acpi_processor_get_power_info_default(); this is undesirable for a
system that's communicating to the OS it doesn't want C-States (missing
_CST, and invalid C2/C3 in FADT).
Make acpi_processor_get_power_info_fadt() return -ENODEV in that case,
so that acpi_processor_get_cstate_info() exits early and doesn't set
pr->flags.power = 1.

[ Upstream commit 29c92a41c6 ]
The arch_kgdb_breakpoint() function defines the kgdb_breakinst symbol
using inline assembly.
1. There's a potential issue where the compiler might inline
arch_kgdb_breakpoint(), which would then define the kgdb_breakinst
symbol multiple times, leading to a linker error.
To prevent this, declare arch_kgdb_breakpoint() as noinline.
Fix follow error with LLVM-19 *only* when LTO_CLANG_FULL:
LD vmlinux.o
ld.lld-19: error: ld-temp.o <inline asm>:3:1: symbol 'kgdb_breakinst' is already defined
kgdb_breakinst: break 2
^
2. Remove "nop" in the inline assembly because it's meaningless for
LoongArch here.
3. Add "STACK_FRAME_NON_STANDARD" for arch_kgdb_breakpoint() to avoid
the objtool warning.

[ Upstream commit c73f0b6964 ]
The calculation of bytes-dropped and bytes_dropped_nested is reversed.
Although it does not affect the final calculation of total_dropped,
it should still be modified.

[ Upstream commit fab0583568 ]
When hw-gro is enabled, the maximum number of header entries that are
needed per wqe (hd_per_wqe) is calculated based on the size of the
reservations among other parameters.
Miscalculation of the size of reservations leads to incorrect
calculation of hd_per_wqe as 0, particularly in the case of large page
size like in aarch64, this prevents the SHAMPO header from being
correctly initialized in the device, ultimately causing the following
cqe err that indicates a violation of PD.
mlx5_core 0000:00:08.0 eth2: ERR CQE on RQ: 0x1180
mlx5_core 0000:00:08.0 eth2: Error cqe on cqn 0x510, ci 0x0, qn 0x1180, opcode 0xe, syndrome 0x4, vendor syndrome 0x32

Use the correct formula for calculating the size of reservations,
precisely it shouldn't be dependent on page size, instead use the
correct multiply of MLX5E_SHAMPO_WQ_BASE_RESRV_SIZE.

[ Upstream commit 67d1a8956d ]
Set FLAG_WWAN instead of FLAG_ETHERNET for RNDIS interfaces on Mobile
Broadband Modems, as opposed to regular Ethernet adapters.
Otherwise NetworkManager gets confused, misjudges the device type,
and wouldn't know it should connect a modem to get the device to work.
What would be the result depends on ModemManager version -- older
ModemManager would end up disconnecting a device after an unsuccessful
probe attempt (if it connected without needing to unlock a SIM), while
a newer one might spawn a separate PPP connection over a tty interface
instead, resulting in a general confusion and no end of chaos.
The only way to get this work reliably is to fix the device type
and have good enough version ModemManager (or equivalent).
