Commit fb396bb4 ("arm64/hugetlb: Drop TLB flush from get_clear_flush()")
removed TLB invalidation from get_clear_flush() [now get_clear_contig()]
on the basis that the core TLB invalidation code is aware of hugetlb
mappings backed by contiguous page-table entries and will cover the
correct virtual address range.

However, this change also resulted in the TLB invalidation being removed
from the "break" step in the break-before-make (BBM) sequence used
internally by huge_ptep_set_{access_flags,wrprotect}(), therefore
making the BBM sequence unsafe irrespective of later invalidation.

Although the architecture is desperately unclear about how exactly
contiguous ptes should be updated in a live page-table, restore TLB
invalidation to our BBM sequence under the assumption that BBM is the
right thing to be doing in the first place.

A regression has been reported by Nicolas Boichat, found while using the
copy_file_range syscall to copy a tracefs file.

Before commit 5dae222a ("vfs: allow copy_file_range to copy across
devices") the kernel would return -EXDEV to userspace when trying to
copy a file across different filesystems.  After this commit, the
syscall doesn't fail anymore and instead returns zero (zero bytes
copied), as this file's content is generated on-the-fly and thus reports
a size of zero.

Another regression has been reported by He Zhe - the assertion of
WARN_ON_ONCE(ret == -EOPNOTSUPP) can be triggered from userspace when
copying from a sysfs file whose read operation may return -EOPNOTSUPP.

Since we do not have test coverage for copy_file_range() between any two
types of filesystems, the best way to avoid these sort of issues in the
future is for the kernel to be more picky about filesystems that are
allowed to do copy_file_range().

This patch restores some cross-filesystem copy restrictions that existed
prior to commit 5dae222a ("vfs: allow copy_file_range to copy across
devices"), namely, cross-sb copy is not allowed for filesystems that do
not implement ->copy_file_range().

Filesystems that do implement ->copy_file_range() have full control of
the result - if this method returns an error, the error is returned to
the user.  Before this change this was only true for fs that did not
implement the ->remap_file_range() operation (i.e.  nfsv3).

Filesystems that do not implement ->copy_file_range() still fall-back to
the generic_copy_file_range() implementation when the copy is within the
same sb.  This helps the kernel can maintain a more consistent story
about which filesystems support copy_file_range().

nfsd and ksmbd servers are modified to fall-back to the
generic_copy_file_range() implementation in case vfs_copy_file_range()
fails with -EOPNOTSUPP or -EXDEV, which preserves behavior of
server-side-copy.

fall-back to generic_copy_file_range() is not implemented for the smb
operation FSCTL_DUPLICATE_EXTENTS_TO_FILE, which is arguably a correct
change of behavior.

Commit f49169c9 ("NFSD: Remove svc_serv_ops::svo_module") removed
calls to module_put_and_kthread_exit() from threads that acted as SUNRPC
servers and had a related svc_serv_ops structure.  This was correct.

It ALSO removed the module_put_and_kthread_exit() call from
nfs4_run_state_manager() which is NOT a SUNRPC service.

Consequently every time the NFSv4 state manager runs the module count
increments and won't be decremented.  So the nfsv4 module cannot be
unloaded.

So restore the module_put_and_kthread_exit() call.

Both PSFP stats and the port stats read by ocelot_check_stats_work() are
indirectly read through the same mechanism - write to STAT_CFG:STAT_VIEW,
read from SYS:STAT:CNT[n].

It's just that for port stats, we write STAT_VIEW with the index of the
port, and for PSFP stats, we write STAT_VIEW with the filter index.

So if we allow them to run concurrently, ocelot_check_stats_work() may
change the view from vsc9959_psfp_counters_get(), and vice versa.

Eric reports that syzbot made short work out of my speculative
fix. Indeed when queue gets detached its tfile->tun remains,
so we would try to stop NAPI twice with a detach(), close()
sequence.

Alternative fix would be to move tun_napi_disable() to
tun_detach_all() and let the NAPI run after the queue
has been detached.

s390x appears to present two RNG interfaces:
- a "TRNG" that gathers entropy using some hardware function; and
- a "DRBG" that takes in a seed and expands it.

Previously, the TRNG was wired up to arch_get_random_{long,int}(), but
it was observed that this was being called really frequently, resulting
in high overhead. So it was changed to be wired up to arch_get_random_
seed_{long,int}(), which was a reasonable decision. Later on, the DRBG
was then wired up to arch_get_random_{long,int}(), with a complicated
buffer filling thread, to control overhead and rate.

Fortunately, none of the performance issues matter much now. The RNG
always attempts to use arch_get_random_seed_{long,int}() first, which
means a complicated implementation of arch_get_random_{long,int}() isn't
really valuable or useful to have around. And it's only used when
reseeding, which means it won't hit the high throughput complications
that were faced before.

So this commit returns to an earlier design of just calling the TRNG in
arch_get_random_seed_{long,int}(), and returning false in arch_get_
random_{long,int}().

Part of what makes the simplification possible is that the RNG now seeds
itself using the TRNG at bootup. But this only works if the TRNG is
detected early in boot, before random_init() is called. So this commit
also causes that check to happen in setup_arch().

    - Re-initialize the vairables of struct devfreq_passive_data when
      PROBE_DEFER happens when cpufreq_get() returns NULL.

    - Use dev_err_probe to mute warning when PROBE_DEFER.

    - Fix cpufreq passive unregister erroring on PROBE_DEFER
      by using the allocated parent_cpu_data list to free resouce
      instead of for_each_possible_cpu().

    - Remove duplicate cpufreq passive unregister and warning when
      PROBE_DEFER.

    - Use HZ_PER_KZH macro in units.h.

    - Fix wrong indentation in SPDX-License line.

 2. Fix reference count leak in exynos-ppmu.c by using of_node_put().

 3. Rework freq_table to be local to devfreq struct

    - struct devfreq_dev_profile includes freq_table array to store
      the supported frequencies. If devfreq driver doesn't initialize
      the freq_table, devfreq core allocates the memory and initializes
      the freq_table.

      On a devfreq PROBE_DEFER, the freq_table in the driver profile
      struct is never reset and may be left in an undefined state. To fix
      this and correctly handle PROBE_DEFER, use a local freq_table and
      max_state in the devfreq struct."

In mlxsw_sp_nexthop6_init(), a next hop is always added to the router
linked list, and mlxsw_sp_nexthop_type_init() is invoked afterwards. When
that function results in an error, the next hop will not have been removed
from the linked list. As the error is propagated upwards and the caller
frees the next hop object, the linked list ends up holding an invalid
object.

A similar issue comes up with mlxsw_sp_nexthop4_init(), where rollback
block does exist, however does not include the linked list removal.

Both IPv6 and IPv4 next hops have a similar issue with next-hop counter
rollbacks. As these were introduced in the same patchset as the next hop
linked list, include the cleanup in this patch.
