a4366b5695 arm64: dts: mediatek: mt8192: Fix CPUs capacity-dmips-mhz 
The capacity-dmips-mhz parameter was miscalculated: this SoC runs
the first (Cortex-A55) cluster at a maximum of 2000MHz and the
second (Cortex-A76) cluster at a maximum of 2200MHz.

In order to calculate the right capacity-dmips-mhz, the following
test was performed:
1. CPUFREQ governor was set to 'performance' on both clusters
2. Ran dhrystone with 500000000 iterations for 10 times on each cluster
3. Calculated the mean result for each cluster
4. Calculated DMIPS/MHz: dmips_mhz = dmips_per_second / cpu_mhz
5. Scaled results to 1024:
   result_c0 = dmips_mhz_c0 / dmips_mhz_c1 * 1024

The mean results for this SoC are:
Cluster 0 (LITTLE): 12016411 Dhry/s
Cluster 1 (BIG): 31702034 Dhry/s

The calculated scaled results are:
Cluster 0: 426.953226899238 (rounded to 427)
Cluster 1: 1024

6970cadb21 arm64: dts: mediatek: mt8192: Add missing dma-ranges to soc node 
In the series "Adjust the dma-ranges for MTK IOMMU", the mtk-iommu
driver was adapted to separate the iova range based on the larb used,
and a dma-ranges property was added to the soc node in the devicetree of
the affected SoCs allowing the whole 16GB iova range to be used. Except
that for mt8192, there was no patch adding dma-ranges.

Add the missing dma-ranges property to the soc node like was done for
mt8195 and mt8186. This fixes the usage of the vcodec, which would
otherwise trigger iommu faults.

6322555dbe arm64: dts: mediatek: mt8173-elm: remove panel model number in DT 
Currently a specific panel number is used in the Elm DTSI, which is
corresponded to a 12" panel. However, according to the official Chrome
OS devices document, Elm refers to Acer Chromebook R13, which, as the
name specifies, uses a 13.3" panel, which comes with EDID information.

As the kernel currently prioritizes the hardcoded timing parameters
matched with the panel number compatible, a wrong timing will be applied
to the 13.3" panel on Acer Chromebook R13, which leads to blank display.

Because the Elm DTSI is shared with Hana board, and Hana corresponds to
multiple devices from 11" to 14", a certain panel model number shouldn't
be present, and driving the panel according to its EDID information is
necessary.

c12753d5fa s390: remove the unneeded select GCC12_NO_ARRAY_BOUNDS 
Commit 0da6e5fd6c ("gcc: disable '-Warray-bounds' for gcc-13 too") makes
config GCC11_NO_ARRAY_BOUNDS to be for disabling -Warray-bounds in any gcc
version 11 and upwards, and with that, removes the GCC12_NO_ARRAY_BOUNDS
config as it is now covered by the semantics of GCC11_NO_ARRAY_BOUNDS.

As GCC11_NO_ARRAY_BOUNDS is yes by default, there is no need for the s390
architecture to explicitly select GCC11_NO_ARRAY_BOUNDS. Hence, the select
GCC12_NO_ARRAY_BOUNDS in arch/s390/Kconfig can simply be dropped.

Remove the unneeded "select GCC12_NO_ARRAY_BOUNDS".

d5ed10bb80 Merge branch 'x86-uaccess-cleanup': x86 uaccess header cleanups 
Merge my x86 uaccess updates branch.

The LAM ("Linear Address Masking") updates in this release made me
unhappy about how "access_ok()" was done, and it actually turned out to
have a couple of small bugs in it too.  This is my cleanup of the code:

 - use the sign bit of the __user pointer rather than masking the
   address and checking it against the TASK_SIZE range.

   We already did this part for the get/put_user() side, but
   'access_ok()' did the naïve "mask and range check" thing, which not
   only generates nasty code, but also ended up meaning that __access_ok
   itself didn't do a good job, and so copy_from_user_nmi() didn't get
   the check right.

 - move all the code that is 64-bit only into the 64-bit version of the
   header file, so that we don't unnecessarily pollute the shared x86
   code and make it look like LAM might work in 32-bit too.

 - fix a bug in the address masking (that doesn't end up mattering: in
   this case the fix was to just remove the buggy code entirely).

 - a couple of trivial cleanups and added commentary about the
   access_ok() rules.

* x86-uaccess-cleanup:
  x86-64: mm: clarify the 'positive addresses' user address rules
  x86: mm: remove 'sign' games from LAM untagged_addr*() macros
  x86: uaccess: move 32-bit and 64-bit parts into proper <asm/uaccess_N.h> header
  x86: mm: remove architecture-specific 'access_ok()' define
  x86-64: make access_ok() independent of LAM
