When the KCOV is enabled all functions get instrumented, unless
the __no_sanitize_coverage attribute is used. To prepare for
__no_sanitize_coverage being applied to __init functions, we have to
handle differences in how GCC's inline optimizations get resolved.
For LoongArch this exposed several places where __init annotations
were missing but ended up being "accidentally correct". So fix these
cases.

The EFI memory map at 'boot_memmap' is crucial for kdump to understand
the primary kernel's memory layout. This memory region, typically part
of EFI Boot Services (BS) data, can be overwritten after ExitBootServices
if not explicitly preserved by the kernel.
This commit addresses this by:
1. Calling memblock_reserve() to reserve the entire physical region
occupied by the EFI memory map (header + descriptors). This prevents
the primary kernel from reallocating and corrupting this area.
2. Setting the EFI_PRESERVE_BS_REGIONS flag in efi.flags. This indicates
that efforts have been made to preserve critical BS code/data regions
which can be useful for other kernel subsystems or debugging.
These changes ensure the original EFI memory map data remains intact,
improving kdump reliability and potentially aiding other EFI-related
functionalities that might rely on preserved BS code/data.

While the GCC and Clang compilers already define __ASSEMBLER__
automatically when compiling assembler code, __ASSEMBLY__ is a macro
that only gets defined by the Makefiles in the kernel. This is bad
since macros starting with two underscores are names that are reserved
by the C language. It can also be very confusing for the developers
when switching between userspace and kernelspace coding, or when
dealing with uapi headers that rather should use __ASSEMBLER__ instead.
So let's now standardize on the __ASSEMBLER__ macro that is provided
by the compilers.
This is almost a completely mechanical patch (done with a simple
"sed -i" statement), with one comment tweaked manually in the
arch/loongarch/include/asm/cpu.h file (it was missing the trailing
underscores).

Don't mix the namespace and controller values, and validate the
per-controller limit when probing the controller. This avoid spurious
failures for controllers with namespaces that have different namespaces
with different logical block sizes, or report the per-namespace values
only for some namespaces.
It also fixes a missing queue_limits_cancel_update in an error path by
removing that error path.

The remove_work will proceed with permanently disconnecting on the
initial final path failure if the head shows no paths after the delay.
If a new path connects while the remove_work is pending, and if that new
path happens to disconnect before that remove_work executes, the delayed
removal should reset based on the most recent path disconnect time, but
queue_delayed_work() won't do anything if the work is already pending.
Attempt to cancel the delayed work when a new path connects, and use
mod_delayed_work() in case the remove_work remains pending anyway.

Marc reported that enabling protected mode on a device with GICv2
doesn't fail gracefully as one would expect, and leads to a host
kernel crash.
As it turns out, the first half of pKVM init happens before the vgic
probe, and so by the time we find out we have a GICv2 we're already
committed to keeping the pKVM vectors installed at EL2 -- pKVM rejects
stub HVCs for obvious security reasons. However, the error path on KVM
init leads to teardown_hyp_mode() which unconditionally frees hypervisor
allocations (including the EL2 stacks and per-cpu pages) under the
assumption that a previous cpu_hyp_uninit() execution has reset the
vectors back to the stubs, which is false with pKVM.
Interestingly, host stage-2 protection is not enabled yet at this point,
so this use-after-free may go unnoticed for a while. The issue becomes
more obvious after the finalize_pkvm() call.
Fix this by keeping track of the CPUs on which pKVM is initialized in
the kvm_hyp_initialized per-cpu variable, and use it from
teardown_hyp_mode() to skip freeing pages that are in fact used.

If an AUX event overruns, the event core layer intends to disable the
event by setting the 'pending_disable' flag. Unfortunately, the event
is not actually disabled afterwards.
In commit:
ca6c21327c6a ("perf: Fix missing SIGTRAPs")
the 'pending_disable' flag was changed to a boolean. However, the
AUX event code was not updated accordingly. The flag ends up holding a
CPU number. If this number is zero, the flag is taken as false and the
IRQ work is never triggered.
Later, with commit:
2b84def990d3 ("perf: Split __perf_pending_irq() out of perf_pending_irq()")
a new IRQ work 'pending_disable_irq' was introduced to handle event
disabling. The AUX event path was not updated to kick off the work queue.
To fix this bug, when an AUX ring buffer overrun is detected, call
perf_event_disable_inatomic() to initiate the pending disable flow.
Also update the outdated comment for setting the flag, to reflect the
boolean values (0 or 1).

As Quentin pointed, the order of free is also wrong, we need to free

host_stage2_adjust_range() tries to find the largest block mapping that
fits within a memory or mmio region (represented by a kvm_mem_range in
this function) during host stage-2 faults under pKVM. To do so, it walks
the host stage-2 page-table, finds the faulting PTE and its level, and
then progressively increments the level until it finds a granule of the
appropriate size. However, the condition in the loop implementing the
above is broken as it checks kvm_level_supports_block_mapping() for the
next level instead of the current, so pKVM may attempt to map a region
larger than can be covered with a single block.
This is not a security problem and is quite rare in practice (the
kvm_mem_range check usually forces host_stage2_adjust_range() to choose a
smaller granule), but this is clearly not the expected behaviour.
Refactor the loop to fix the bug and improve readability.

The state of the vcpu's MI line should be asserted when its
ICH_HCR_EL2.En is set and ICH_MISR_EL2 is non-zero. Using bitwise AND
(&=) directly for this calculation will not give us the correct result
when the LSB of the vcpu's ICH_MISR_EL2 isn't set. Correct this by
directly computing the line level with a logical AND operation.

bug where calling bch2_run_explicit_recovery_pass() would only return
the error code to rewind recovery for the first call that scheduled that
recovery pass.
If the error code from the first call was swallowed (because it was
called by an asynchronous codepath), subsequent calls would go "ok, this
pass is already marked as needing to run" and return 0.
Fixing this ensures that check_topology bails out to run btree_node_scan

syzbot reported a warning below during atm_dev_register(). [0]
Before creating a new device and procfs/sysfs for it, atm_dev_register()
looks up a duplicated device by __atm_dev_lookup(). These operations are
done under atm_dev_mutex.
However, when removing a device in atm_dev_deregister(), it releases the
mutex just after removing the device from the list that __atm_dev_lookup()
iterates over.
So, there will be a small race window where the device does not exist on
the device list but procfs/sysfs are still not removed, triggering the
splat.
Let's hold the mutex until procfs/sysfs are removed in
atm_dev_deregister().

validate_addr() checks whether the address returned by mmap() lies in the
low or high VA space, according to whether a high addr hint was passed or
not. The fix commit mentioned below changed the code in such a way that
this function will always return failure when passed high_addr == 1; addr
will be >= HIGH_ADDR_MARK always, we will fall down to "if (addr >
HIGH_ADDR_MARK)" and return failure. Fix this.

The dm_crypt code fails to build without CONFIG_KEYS:
kernel/crash_dump_dm_crypt.c: In function 'restore_dm_crypt_keys_to_thread_keyring':
kernel/crash_dump_dm_crypt.c:105:9: error: unknown type name 'key_ref_t'; did you mean 'key_ref_put'?
There is a mix of 'select KEYS' and 'depends on KEYS' in Kconfig,
so there is no single obvious solution here, but generally using 'depends on'
makes more sense and is less likely to cause dependency loops.

The WARN_ON_ONCE is introduced on truncate_folio_batch_exceptionals() to
capture whether the filesystem has removed all DAX entries or not.
And the fix has been applied on the filesystem xfs and ext4 by the commit
0e2f80afcfa6 ("fs/dax: ensure all pages are idle prior to filesystem
unmount").
Apply the missed fix on filesystem fuse to fix the runtime warning:

memcg_path_store() assigns a newly allocated memory buffer to
filter->memcg_path, without deallocating the previously allocated and
assigned memory buffer. As a result, users can leak kernel memory by
continuously writing a data to memcg_path DAMOS sysfs file. Fix the leak
by deallocating the previously set memory buffer.

percpu variable tag->counters
When loading a module, as long as the module has memory allocation
operations, kmemleak produces a false positive report that resembles the
following:
unreferenced object (percpu) 0x7dfd232a1650 (size 16):
comm "modprobe", pid 1301, jiffies 4294940249
hex dump (first 16 bytes on cpu 2):

el0t_64_sync_handler+0x10c/0x138
el0t_64_sync+0x1ac/0x1b0
This is because the module can only indirectly reference
alloc_tag_counters through the alloc_tag section, which misleads kmemleak.
However, we don't have a kmemleak ignore interface for percpu allocations
yet. So let's create one and invoke it for tag->counters.

Root cause is that numgrps is set to 0, and ZERO_SIZE_PTR is returned from
kcalloc(), and later ZERO_SIZE_PTR will be deferenced.
Fix the problem by checking numgrps first in group_cpus_evenly(), and
return NULL directly if numgrps is zero.

In isolate_or_dissolve_huge_folio(), after acquiring the hugetlb_lock, it
is only for the purpose of obtaining the correct hstate, which is then
passed to alloc_and_dissolve_hugetlb_folio().
alloc_and_dissolve_hugetlb_folio() itself also acquires the hugetlb_lock.
We can have alloc_and_dissolve_hugetlb_folio() obtain the hstate by
itself, so that isolate_or_dissolve_huge_folio() no longer needs to
acquire the hugetlb_lock. In addition, we keep the folio_test_hugetlb()
check within isolate_or_dissolve_huge_folio(). By doing so, we can avoid
disrupting the normal path by vainly holding the hugetlb_lock.
replace_free_hugepage_folios() has the same issue, and we should address
it as well.
Addresses a possible performance problem which was added by the hotfix
113ed54ad276 ("mm/hugetlb: fix kernel NULL pointer dereference when

is_zero_pfn() does not work for the huge zero folio. Fix it by using
is_huge_zero_pmd().
This can cause the PAGEMAP_SCAN ioctl against /proc/pid/pagemap to
present pages as PAGE_IS_PRESENT rather than as PAGE_IS_PFNZERO.
Found by code inspection.

Jakub Kicinski says:
====================
netlink: specs: enforce strict naming of properties
I got annoyed once again by the name properties in the ethtool spec
which use underscore instead of dash. I previously assumed that there
is a lot of such properties in the specs so fixing them now would
be near impossible. On a closer look, however, I only found 22
(rough grep suggests we have ~4.8k names in the specs, so bad ones
are just 0.46%).
Add a regex to the JSON schema to enforce the naming, fix the few
bad names. I was hoping we could start enforcing this from newer
families, but there's no correlation between the protocol and the
number of errors. If anything classic netlink has more recently
added specs so it has fewer errors.
The regex is just for name properties which will end up visible
to the user (in Python or YNL CLI). I left the c-name properties
alone, those don't matter as much. C codegen rewrites them, anyway.
I'm not updating the spec for genetlink-c. Looks like it has no
users, new families use genetlink, all old ones need genetlink-legacy.
If these patches are merged I will remove genetlink-c completely
in net-next.

Add a regexp to make sure all names which may end up being visible
to the user consist of lower case characters, numbers and dashes.
Underscores keep sneaking into the specs, which is not visible
in the C code but makes the Python and alike inconsistent.
Note that starting with a number is okay, as in C the full
name will include the family name.
For legacy families we can't enforce the naming in the family
name or the multicast group names, as these are part of the
binary uAPI of the kernel.
For classic netlink we need to allow capital letters in names
of struct members. TC has some structs with capitalized members.

We're trying to add a strict regexp for the name format in the spec.
Underscores will not be allowed, dashes should be used instead.
This makes no difference to C (codegen, if used, replaces special
chars in names) but it gives more uniform naming in Python.
