This SoC has a DMA controller with tx/rx channels for all of the
UART controller IPs: add the apdma node and wire up the DMAs on
all controllers.
When one of the UART controllers is used as a serial console,
the DMA will be automatically ignored.

The UART nodes had a dummy clock for early bringup, as it is
expected that these are left on by the bootloader: now that
the pericfg clock controller is supported, we can replace
them with the real clocks.

In cherry projects, we use edptx as the internal display interface
and use dptx as the external display interface. To support this, we
need to add more properties.
- Add pinctrls for edptx and dptx.
- Add ports for edptx and dptx.
The port connections for the internal and external display:
dp-intf0 -> edptx -> panel
dp-intf1 -> dptx
The edptx endpoint is kept empty for now, as the panel addition will
come in a later commit.

The capacity-dmips-mhz parameter was miscalculated: this SoC runs
the first (Cortex-A55) cluster at a maximum of 2000MHz and the
second (Cortex-A78) cluster at a maximum of 3000MHz.
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. Calculate the mean result for each cluster
4. Calculate DMIPS/MHz: dmips_mhz = dmips_per_second / cpu_mhz
5. Scale results to 1024:
result_c0 = (dmips_mhz_c0 - min_dmips_mhz(c0, c1)) /
(max_dmips_mhz(c0, c1) - min_dmips_mhz(c0, c1)) * 1024
The mean results for this SoC are:
Cluster 0 (LITTLE): 11990400 Dhry/s
Cluster 1 (BIG): 59809036 Dhry/s
The calculated scaled results are:
Cluster 0: 307,934312801831 (rounded to 308)
Cluster 1: 1024

Pull more random number generator updates from Jason Donenfeld:
"This time with some large scale treewide cleanups.
The intent of this pull is to clean up the way callers fetch random
integers. The current rules for doing this right are:
- If you want a secure or an insecure random u64, use get_random_u64()
- If you want a secure or an insecure random u32, use get_random_u32()
The old function prandom_u32() has been deprecated for a while
now and is just a wrapper around get_random_u32(). Same for
get_random_int().
- If you want a secure or an insecure random u16, use get_random_u16()
- If you want a secure or an insecure random u8, use get_random_u8()
- If you want secure or insecure random bytes, use get_random_bytes().
The old function prandom_bytes() has been deprecated for a while
now and has long been a wrapper around get_random_bytes()
- If you want a non-uniform random u32, u16, or u8 bounded by a
certain open interval maximum, use prandom_u32_max()
I say "non-uniform", because it doesn't do any rejection sampling
or divisions. Hence, it stays within the prandom_*() namespace, not
the get_random_*() namespace.
I'm currently investigating a "uniform" function for 6.2. We'll see
what comes of that.
By applying these rules uniformly, we get several benefits:
- By using prandom_u32_max() with an upper-bound that the compiler
can prove at compile-time is ≤65536 or ≤256, internally
get_random_u16() or get_random_u8() is used, which wastes fewer
batched random bytes, and hence has higher throughput.
- By using prandom_u32_max() instead of %, when the upper-bound is
not a constant, division is still avoided, because
prandom_u32_max() uses a faster multiplication-based trick instead.
- By using get_random_u16() or get_random_u8() in cases where the
return value is intended to indeed be a u16 or a u8, we waste fewer
batched random bytes, and hence have higher throughput.
This series was originally done by hand while I was on an airplane
without Internet. Later, Kees and I worked on retroactively figuring
out what could be done with Coccinelle and what had to be done
manually, and then we split things up based on that.
So while this touches a lot of files, the actual amount of code that's
hand fiddled is comfortably small"

The clk rate range series needed another week to fully bake. Maxime
fixed the bug that broke clk notifiers and prevented this from being
included in the first pull request. He also added a unit test on top to
make sure it doesn't break so easily again. The majority of the series
fixes up how the clk_set_rate_*() APIs work, particularly around when
the rate constraints are dropped and how they move around when
reparenting clks. Overall it's a much needed improvement to the clk rate
range APIs that used to be pretty broken if you looked sideways.
Beyond the core changes there are a few driver fixes for a compilation
issue or improper data causing clks to fail to register or have the
wrong parents. These are good to get in before the first -rc so that the
system actually boots on the affected devices.

This reverts commit 78e5a33994 ("cpumask: fix checking valid cpu range").
syzbot is hitting WARN_ON_ONCE(cpu >= nr_cpumask_bits) warning at
cpu_max_bits_warn() [1], for commit 78e5a33994 ("cpumask: fix checking
valid cpu range") is broken. Obviously that patch hits WARN_ON_ONCE()
when e.g. reading /proc/cpuinfo because passing "cpu + 1" instead of
"cpu" will trivially hit cpu == nr_cpumask_bits condition.
Although syzbot found this problem in linux-next.git on 2022/09/27 [2],
this problem was not fixed immediately. As a result, that patch was
sent to linux.git before the patch author recognizes this problem, and
syzbot started failing to test changes in linux.git since 2022/10/10
[3].
Andrew Jones proposed a fix for x86 and riscv architectures [4]. But
[2] and [5] indicate that affected locations are not limited to arch
code. More delay before we find and fix affected locations, less tested
kernel (and more difficult to bisect and fix) before release.
We should have inspected and fixed basically all cpumask users before
applying that patch. We should not crash kernels in order to ask
existing cpumask users to update their code, even if limited to
CONFIG_DEBUG_PER_CPU_MAPS=y case.

When building with a RISC-V kernel with DWARF5 debug info using clang
and the GNU assembler, several instances of the following error appear:
/tmp/vgettimeofday-48aa35.s:2963: Error: non-constant .uleb128 is not supported
Dumping the .s file reveals these .uleb128 directives come from
.debug_loc and .debug_ranges:
.Ldebug_loc0:
.byte 4 # DW_LLE_offset_pair
.uleb128 .Lfunc_begin0-.Lfunc_begin0 # starting offset
.uleb128 .Ltmp1-.Lfunc_begin0 # ending offset
.byte 1 # Loc expr size
.byte 90 # DW_OP_reg10
.byte 0 # DW_LLE_end_of_list
.Ldebug_ranges0:
.byte 4 # DW_RLE_offset_pair
.uleb128 .Ltmp6-.Lfunc_begin0 # starting offset
.uleb128 .Ltmp27-.Lfunc_begin0 # ending offset
.byte 4 # DW_RLE_offset_pair
.uleb128 .Ltmp28-.Lfunc_begin0 # starting offset
.uleb128 .Ltmp30-.Lfunc_begin0 # ending offset
.byte 0 # DW_RLE_end_of_list
There is an outstanding binutils issue to support a non-constant operand
to .sleb128 and .uleb128 in GAS for RISC-V but there does not appear to
be any movement on it, due to concerns over how it would work with
linker relaxation.
To avoid these build errors, prevent DWARF5 from being selected when
using clang and an assembler that does not have support for these symbol
deltas, which can be easily checked in Kconfig with as-instr plus the
small test program from the dwz test suite from the binutils issue.

After commit d6a71648db ("mm/slab: kmalloc: pass requests larger than
order-1 page to page allocator"), SLAB passes large ( > PAGE_SIZE * 2)
requests to buddy like SLUB does.
SLAB has been using kmalloc caches to allocate freelist_idx_t array for
off slab caches. But after the commit, freelist_size can be bigger than
KMALLOC_MAX_CACHE_SIZE.
Instead of using pointer to kmalloc cache, use kmalloc_node() and only
check if the kmalloc cache is off slab during calculate_slab_order().
If freelist_size > KMALLOC_MAX_CACHE_SIZE, no looping condition happens
as it allocates freelist_idx_t array directly from buddy.

Change notification is a commonly supported feature by most servers,
but the current ioctl to request notification when a directory is
changed does not return the information about what changed
(even though it is returned by the server in the SMB3 change
notify response), it simply returns when there is a change.
This ioctl improves upon CIFS_IOC_NOTIFY by returning the notify
information structure which includes the name of the file(s) that
changed and why. See MS-SMB2 2.2.35 for details on the individual
filter flags and the file_notify_information structure returned.
To use this simply pass in the following (with enough space
to fit at least one file_notify_information structure)
struct __attribute__((__packed__)) smb3_notify {
uint32_t completion_filter;
bool watch_tree;
uint32_t data_len;
uint8_t data[];
} __packed;
using CIFS_IOC_NOTIFY_INFO 0xc009cf0b
or equivalently _IOWR(CIFS_IOCTL_MAGIC, 11, struct smb3_notify_info)
The ioctl will block until the server detects a change to that
directory or its subdirectories (if watch_tree is set).
