faf88ed1c0 remoteproc: meson-mx-ao-arc: fix a bit test
The MESON_AO_RPROC_SRAM_USABLE_BITS macro is used like this:

        if (priv->sram_pa & ~MESON_AO_RPROC_SRAM_USABLE_BITS) {
                dev_err(dev, "SRAM address contains unusable bits\n");

The problem is that "->sram_pa" is type phys_addr_t which is potentially
64 bits.  That means the MESON_AO_RPROC_SRAM_USABLE_BITS macro needs to
be a 64 bit type as well to ensure that high 32 bits are cleared.

6cb58ea897 remoteproc: meson-mx-ao-arc: Add a driver for the AO ARC remote procesor
Amlogic Meson6, Meson8, Meson8b and Meson8m2 embed an ARC core in the
Always-On (AO) power-domain. This is typically used for waking up the
ARM cores after system suspend.

The configuration is spread across three different registers:
- AO_REMAP_REG0 which must be programmed to zero, it's actual purpose
  is unknown. There is a second remap register which is not used in the
  vendor kernel (which served as reference for this driver).
- AO_CPU_CNTL is used to start and stop the ARC core.
- AO_SECURE_REG0 in the SECBUS2 register area with unknown purpose.

To boot the ARC core we also need to enable it's gate clock and trigger
a reset.

The actual code for this ARC core can come from an ELF binary, for
example by building the Zephyr RTOS for an ARC EM4 core and then taking
"zephyr.elf" as firmware. This executable does not have any "rsc table"
so we are skipping rproc_elf_load_rsc_table (rproc_ops.parse_fw) and
rproc_elf_find_loaded_rsc_table (rproc_ops.find_loaded_rsc_table).

c1fe10d238 remoteproc: qcom: q6v5: Use qmp_send to update co-processor load state
The power domains exposed by the AOSS QMP driver control the load state
resources linked to modem, adsp, cdsp remoteprocs. These are used to
notify the Always on Subsystem (AOSS) that a particular co-processor is
up/down. AOSS uses this information to wait for the co-processors to
suspend before starting its sleep sequence.

These co-processors enter low-power modes independent to that of the
application processor and the load state resources linked to them are
expected to remain unaltered across system suspend/resume cycles. To
achieve this behavior lets stop using the power-domains exposed by the
AOSS QMP node and replace them with generic qmp_send interface instead.

e73c632b18 dt-bindings: remoteproc: qcom: pas: Add QMP property
The load state power-domain, used by the co-processors to notify the
Always on Subsystem (AOSS) that a particular co-processor is up/down,
suffers from the side-effect of changing states during suspend/resume.
However the co-processors enter low-power modes independent to that of
the application processor and their states are expected to remain
unaltered across system suspend/resume cycles. To achieve this behavior
let's drop the load state power-domain and replace them with the qmp
property for all SoCs supporting low power mode signalling.

Due to the current broken load state implementation, we can afford the
binding breakage that ensues and the remoteproc functionality will remain
the same when using newer kernels with older dtbs.

b5b65f1398 perf tools changes for v5.15: 2nd batch
- Add missing fields and remove some duplicate fields when printing a perf_event_attr.
 
 - Fix hybrid config terms list corruption.
 
 - Update kernel header copies, some resulted in new kernel features being
   automagically added to 'perf trace' syscall/tracepoint argument id->string translators.
 
 - Add a file generated during the documentation build to .gitignore.
 
 - Add an option to build without libbfd, as some distros, like Debian consider
   its ABI unstable.
 
 - Add support to print a textual representation of IBS raw sample data in 'perf report'.
 
 - Fix bpf 'perf test' sample mismatch reporting
 
 - Fix passing arguments to stackcollapse report in a 'perf script' python script.
 
 - Allow build-id with trailing zeros.
 
 - Look for ImageBase in PE file to compute .text offset.

d8e988b62f Misc driver fix for 5.15-rc1
Here is a single patch for 5.15-rc1, for the lkdtm misc driver.
 
 It resolves a build issue that many people were hitting with your
 current tree, and Kees and others felt would be good to get merged
 before -rc1 comes out, to prevent them from having to constantly hit it
 as many development trees restart on -rc1, not older -rc releases.
 
 It has NOT been in linux-next, but has passed 0-day testing and looks
 "obviously correct" when reviewing it locally :)

Merge tag '5.15-rc-cifs-part2' of git://git.samba.org/sfrench/cifs-2.6

Pull smbfs updates from Steve French:
 "cifs/smb3 updates:

   - DFS reconnect fix

   - begin creating common headers for server and client

   - rename the cifs_common directory to smbfs_common to be more
     consistent ie change use of the name cifs to smb (smb3 or smbfs is
     more accurate, as the very old cifs dialect has long been
     superseded by smb3 dialects).

  In the future we can rename the fs/cifs directory to fs/smbfs.

  This does not include the set of multichannel fixes nor the two
  deferred close fixes (they are still being reviewed and tested)"

* tag '5.15-rc-cifs-part2' of git://git.samba.org/sfrench/cifs-2.6:
  cifs: properly invalidate cached root handle when closing it
  cifs: move SMB FSCTL definitions to common code
