When unloading a module, its state is changing MODULE_STATE_LIVE ->
MODULE_STATE_GOING -> MODULE_STATE_UNFORMED. Each change will take
a time. `is_module_text_address()` and `__module_text_address()`
works with MODULE_STATE_LIVE and MODULE_STATE_GOING.
If we use `is_module_text_address()` and `__module_text_address()`
separately, there is a chance that the first one is succeeded but the
next one is failed because module->state becomes MODULE_STATE_UNFORMED
between those operations.
In `check_kprobe_address_safe()`, if the second `__module_text_address()`
is failed, that is ignored because it expected a kernel_text address.
But it may have failed simply because module->state has been changed
to MODULE_STATE_UNFORMED. In this case, arm_kprobe() will try to modify
non-exist module text address (use-after-free).
To fix this problem, we should not use separated `is_module_text_address()`
and `__module_text_address()`, but use only `__module_text_address()`
once and do `try_module_get(module)` which is only available with
MODULE_STATE_LIVE.

When enabling both CONFIG_KFENCE and CONFIG_DEBUG_SG, I get the

[ 2.502912] [<9000000004161c48>] ret_from_kernel_thread+0xc/0xa4
The backtrace is always similar but not exactly the same. It is always
triggered from cryptomgr_test, but not always from the same test.
Analysis shows that with CONFIG_KFENCE active, the address returned from
kmalloc() and friends is not always below vm_map_base. It is allocated
by kfence_alloc() which at least sometimes seems to get its memory from
an address space above vm_map_base. This causes __virt_addr_valid() to
return false for the affected objects.
Let __virt_addr_valid() return 1 for kfence pool addresses, this make
virt_addr_valid()/__virt_addr_valid() work with KFENCE.

KFENCE changes virt_to_page() to be able to translate tlb mapped virtual
addresses, but forget to change virt_to_phys()/phys_to_virt() and other
translation functions as well. This patch fix it, otherwise some drivers
(such as nvme and virtio-blk) cannot work with KFENCE.
All {virt, phys, page, pfn} translation functions are updated:
1, virt_to_pfn()/pfn_to_virt();
2, virt_to_page()/page_to_virt();
3, virt_to_phys()/phys_to_virt().
DMW/TLB mapped addresses are distinguished by comparing the vaddress
with vm_map_base in virt_to_xyz(), and we define WANT_PAGE_VIRTUAL in
the KFENCE case for the reverse translations, xyz_to_virt().

LoongArch will override page_to_virt() which use page_address() in the
KFENCE case (by defining WANT_PAGE_VIRTUAL/HASHED_PAGE_VIRTUAL). So move
lowmem_page_address() a little later to avoid such build errors:
error: implicit declaration of function 'page_address'.

Binding devm_led_classdev_register() to the netdev is problematic
because on module removal we get a RTNL-related deadlock. Fix this
by avoiding the device-managed LED functions.
Note: We can safely call led_classdev_unregister() for a LED even
if registering it failed, because led_classdev_unregister() detects
this and is a no-op in this case.

When the driver notices fw_status == 0xff it tries to perform a PCI
reset on itself via pci_reset_function() in the context of the driver's
health thread. However, pdsc_reset_prepare calls
pdsc_stop_health_thread(), which attempts to stop/flush the health
thread. This results in a deadlock because the stop/flush will never
complete since the driver called pci_reset_function() from the health
thread context. Fix by changing the pdsc_check_pci_health_function()
to queue a newly introduced pdsc_pci_reset_thread() on the pdsc's
work queue.
Unloading the driver in the fw_down/dead state uncovered another issue,
which can be seen in the following trace:

In current implemenation ODM mode is only reset when the last plane is
removed from dc state. For any dc validate we will always remove all
current planes and add new planes. However when switching from no planes
to 1 plane, ODM mode is not reset because no planes get removed. This
has caused an issue where we kept ODM combine when it should have been
remove when a plane is added. The change is to reset ODM mode when
adding the first plane.

There are cases where soft reset seems to succeed, but
does not, so always use mode1/2 for now.

Currently, with F32 HWS GPU reset is only when unmap queue fails.
However, if compute queue doesn't repond to preemption request in time
unmap will return without any error. In this case, only preemption error
is logged and Reset is not triggered. Call GPU reset in this case also.

Although ipv6_get_ifaddr walks inet6_addr_lst under the RCU lock, it
still means hlist_for_each_entry_rcu can return an item that got removed
from the list. The memory itself of such item is not freed thanks to RCU
but nothing guarantees the actual content of the memory is sane.
In particular, the reference count can be zero. This can happen if
ipv6_del_addr is called in parallel. ipv6_del_addr removes the entry
from inet6_addr_lst (hlist_del_init_rcu(&ifp->addr_lst)) and drops all
references (__in6_ifa_put(ifp) + in6_ifa_put(ifp)). With bad enough
timing, this can happen:
1. In ipv6_get_ifaddr, hlist_for_each_entry_rcu returns an entry.
2. Then, the whole ipv6_del_addr is executed for the given entry. The
reference count drops to zero and kfree_rcu is scheduled.
3. ipv6_get_ifaddr continues and tries to increments the reference count
(in6_ifa_hold).
4. The rcu is unlocked and the entry is freed.
5. The freed entry is returned.
Prevent increasing of the reference count in such case. The name
in6_ifa_hold_safe is chosen to mimic the existing fib6_info_hold_safe.

====================
net: start to replace copy_from_sockptr()
We got several syzbot reports about unsafe copy_from_sockptr()
calls. After fixing some of them, it appears that we could
use a new helper to factorize all the checks in one place.
This series targets net tree, we can later start converting
many call sites in net-next.
