When adjusting the PTP clock, the base time of the TAS configuration
will become unreliable. We need reset the TAS configuration by using a
new base time.
For example, if the driver gets a base time 0 of Qbv configuration from
user, and current time is 20000. The driver will set the TAS base time
to be 20000. After the PTP clock adjustment, the current time becomes
10000. If the TAS base time is still 20000, it will be a future time,
and TAS entry list will stop running. Another example, if the current
time becomes to be 10000000 after PTP clock adjust, a large time offset
can cause the hardware to hang.
This patch introduces a tas_clock_adjust() function to reset the TAS
module by using a new base time after the PTP clock adjustment. This can
avoid issues above.
Due to PTP clock adjustment can occur at any time, it may conflict with
the TAS configuration. We introduce a new TAS lock to serialize the
access to the TAS registers.

As a part of patch series about wrong trigger register() and get()
calls order in the some IIO drivers trigger initialization path:
https://lore.kernel.org/all/20220524181150.9240-1-ddrokosov@sberdevices.ru/
runtime WARN_ONCE() is added to alarm IIO driver authors who make such
a mistake.
When an IIO driver allocates a new IIO trigger, it should register it
before calling the get() operation. In other words, each IIO driver
must abide by IIO trigger alloc()/register()/get() calls order.

Some PMIC functions such as the RRADC need to be aware of the PMIC
chip revision information to implement errata or otherwise adjust
behaviour, export the PMIC information to enable this.
This is specifically required to enable the RRADC to adjust
coefficients based on which chip fab the PMIC was produced in,
this can vary per unique device and therefore has to be read at
runtime.

2) There are some bpf_func_proto structs marked as extern which can
instead be statically defined.

In order to allow multiple modules to operate MUTEX hardware through
a common interfrace, two flexible indexes "mtk_mutex_mod_index" and
"mtk_mutex_sof_index" need to be added to replace original component
ID so that like DDP and MDP can add their own MOD table or SOF
settings independently.
In addition, 2 generic interface "mtk_mutex_write_mod" and
"mtk_mutex_write_sof" have been added, which is expected to replace
the "mtk_mutex_add_comp" and "mtk_mutex_remove_comp" pair originally
dedicated to DDP in the future.

Various places like I/O schedulers or the QOS infrastructure try to
register debugfs files on demans, which can race with creating and
removing the main queue debugfs directory. Use the existing
debugfs_mutex to serialize all debugfs operations that rely on
q->debugfs_dir or the directories hanging off it.
To make the teardown code a little simpler declare all debugfs dentry
pointers and not just the main one uncoditionally in blkdev.h.
Move debugfs_mutex next to the dentries that it protects and document
what it is used for.

When the driver receives an event interrupt, the driver will enable
the event interrupt after handling all completed tasks on the function,
tasks on the function are parsed through only one thread. If the task's
user callback takes time, other tasks on the function will be blocked.
Therefore, the event irq processing is modified as follows:
1. Obtain the ID of the queue that completes the task.
2. Enable event interrupt.
3. Parse the completed tasks in the queue and call the user callback.
Enabling event interrupt in advance can quickly report pending event
interrupts and process tasks in multiple threads.

(which is a 64-bit type on 64-bit architectures) but actually the packed
masks occupy only 20 bits (7 PIO modes, 5 MWDMA modes, and 8 UDMA modes)
and the PIO/MWDMA/UDMA masks easily fit into just 8 bits each, so we can

The new helpers bpf_tcp_raw_{gen,check}_syncookie_ipv{4,6} allow an XDP
program to generate SYN cookies in response to TCP SYN packets and to
check those cookies upon receiving the first ACK packet (the final
packet of the TCP handshake).
Unlike bpf_tcp_{gen,check}_syncookie these new helpers don't need a
listening socket on the local machine, which allows to use them together
with synproxy to accelerate SYN cookie generation.

Before this commit, the BPF verifier required ARG_PTR_TO_MEM arguments
to be followed by ARG_CONST_SIZE holding the size of the memory region.
The helpers had to check that size in runtime.
There are cases where the size expected by a helper is a compile-time
constant. Checking it in runtime is an unnecessary overhead and waste of
BPF registers.
This commit allows helpers to accept pointers to memory without the
corresponding ARG_CONST_SIZE, given that they define the memory region
size in struct bpf_func_proto and use ARG_PTR_TO_FIXED_SIZE_MEM type.
arg_size is unionized with arg_btf_id to reduce the kernel image size,
and it's valid because they are used by different argument types.

Patch series "Allow to kexec with initramfs larger than 2G", v2.
Currently, the largest initramfs that is supported by kexec_file_load()
syscall is 2G.
This is because kernel_read_file() returns int, and is limited to INT_MAX
or 2G.
On the other hand, there are kexec based boot loaders (i.e. u-root), that
may need to boot netboot images that might be larger than 2G.
The first patch changes the return type from int to ssize_t in
kernel_read_file* functions.
The second patch increases the maximum initramfs file size to 4G.
Tested: verified that can kexec_file_load() works with 4G initramfs
on x86_64.
This patch (of 2):
Currently, the maximum file size that is supported is 2G. This may be too
small in some cases. For example, kexec_file_load() system call loads
initramfs. In some netboot cases initramfs can be rather large.
Allow to use up-to ssize_t bytes. The callers still can limit the maximum
file size via buf_size.

A cast inside __builtin_constant_p doesn't do anything since it should
evaluate as constant at compile time irrespective of this cast. Instead,
I moved this cast outside the ternary to ensure the return type is as
expected.
Additionally, if __HAVE_BUILTIN_BSWAP16__ was not defined then __swab16 is
actually returning an `int` not a `u16` due to integer promotion.
As Al Viro notes:
You *can't* get smaller-than-int out of ? :, same as you can't get it
out of addition, etc.
This also fixes some clang -Wformat warnings involving default
argument promotion.

__register_pernet_operations() executes init hook of registered
pernet_operation structure in all existing net namespaces.
Typically, these hooks are called by a process associated with the
specified net namespace, and all __GFP_ACCOUNT marked allocation are
accounted for corresponding container/memcg.
However __register_pernet_operations() calls the hooks in the same
context, and as a result all marked allocations are accounted to one memcg
for all processed net namespaces.
This patch adjusts active memcg for each net namespace and helps to
account memory allocated inside ops_init() into the proper memcg.

Currently mem_cgroup_from_obj() is not working properly with objects
allocated using vmalloc(). It creates problems in some cases, when it's
called for static objects belonging to modules or generally allocated
using vmalloc().
This patch makes mem_cgroup_from_obj() safe to be called on objects
allocated using vmalloc().
It also introduces mem_cgroup_from_slab_obj(), which is a faster version
to use in places when we know the object is either a slab object or a
generic slab page (e.g. when adding an object to a lru list).

kmemleak_alloc_phys()
Patch series "mm: kmemleak: store objects allocated with physical address
separately and check when scan", v4.
The kmemleak_*_phys() interface uses "min_low_pfn" and "max_low_pfn" to
check address. But on some architectures, kmemleak_*_phys() is called
before those two variables initialized. The following steps will be
taken:
1) Add OBJECT_PHYS flag and rbtree for the objects allocated
with physical address
2) Store physical address in objects if allocated with OBJECT_PHYS
3) Check the boundary when scan instead of in kmemleak_*_phys()
This patch set will solve:

Matthew Wilcox reported that, while he was looking at memmove_page(), he
realized that it can't actually work.
The reasons are hidden in its implementation, which makes use of memmove()
on logical addresses provided by kmap_local_page(). memmove() does the
wrong thing when it tests "if (dest <= src)".
Therefore, delete memmove_page().
No need to change any other code because we have no call sites of
memmove_page() across the whole kernel.

I observed that for each of the shared file-backed page faults, we're very
likely to retry one more time for the 1st write fault upon no page. It's
because we'll need to release the mmap lock for dirty rate limit purpose
with balance_dirty_pages_ratelimited() (in fault_dirty_shared_page()).
Then after that throttling we return VM_FAULT_RETRY.
We did that probably because VM_FAULT_RETRY is the only way we can return
to the fault handler at that time telling it we've released the mmap lock.
However that's not ideal because it's very likely the fault does not need
to be retried at all since the pgtable was well installed before the
throttling, so the next continuous fault (including taking mmap read lock,
walk the pgtable, etc.) could be in most cases unnecessary.
It's not only slowing down page faults for shared file-backed, but also add
more mmap lock contention which is in most cases not needed at all.
To observe this, one could try to write to some shmem page and look at
"pgfault" value in /proc/vmstat, then we should expect 2 counts for each
shmem write simply because we retried, and vm event "pgfault" will capture
that.
To make it more efficient, add a new VM_FAULT_COMPLETED return code just to
show that we've completed the whole fault and released the lock. It's also
a hint that we should very possibly not need another fault immediately on
this page because we've just completed it.
This patch provides a ~12% perf boost on my aarch64 test VM with a simple
program sequentially dirtying 400MB shmem file being mmap()ed and these are
the time it needs:
Before: 650.980 ms (+-1.94%)
After: 569.396 ms (+-1.38%)
I believe it could help more than that.
We need some special care on GUP and the s390 pgfault handler (for gmap
code before returning from pgfault), the rest changes in the page fault
handlers should be relatively straightforward.
Another thing to mention is that mm_account_fault() does take this new
fault as a generic fault to be accounted, unlike VM_FAULT_RETRY.
I explicitly didn't touch hmm_vma_fault() and break_ksm() because they do
not handle VM_FAULT_RETRY even with existing code, so I'm literally keeping
them as-is.

uprobes work by raising a trap, setting a task flag from within the
interrupt handler, and processing the actual work for the uprobe on the
way back to userspace. As a result, uprobe handlers already execute in a
might_fault/_sleep context. The primary obstacle to sleepable bpf uprobe
programs is therefore on the bpf side.
Namely, the bpf_prog_array attached to the uprobe is protected by normal
rcu. In order for uprobe bpf programs to become sleepable, it has to be
protected by the tasks_trace rcu flavor instead (and kfree() called after
a corresponding grace period).
Therefore, the free path for bpf_prog_array now chains a tasks_trace and
normal grace periods one after the other.
Users who iterate under tasks_trace read section would
be safe, as would users who iterate under normal read sections (from
non-sleepable locations).
The downside is that the tasks_trace latency affects all perf_event-attached
bpf programs (and not just uprobe ones). This is deemed safe given the
possible attach rates for kprobe/uprobe/tp programs.
Separately, non-sleepable programs need access to dynamically sized
rcu-protected maps, so bpf_run_prog_array_sleepables now conditionally takes
an rcu read section, in addition to the overarching tasks_trace section.

In order to add a version of bpf_prog_run_array which accesses the
bpf_prog->aux member, bpf_prog needs to be more than a forward
declaration inside bpf.h.
Given that filter.h already includes bpf.h, this merely reorders
the type declarations for filter.h users. bpf.h users now have access to
bpf_prog internals.

Currently unpoison_memory(unsigned long pfn) is designed for soft
poison(hwpoison-inject) only. Since 17fae1294ad9d, the KPTE gets cleared
on a x86 platform once hardware memory corrupts.
Unpoisoning a hardware corrupted page puts page back buddy only, the
kernel has a chance to access the page with *NOT PRESENT* KPTE. This
leads BUG during accessing on the corrupted KPTE.
