When CONFIG_CMDLINE_EXTEND is set, the core kernel command line handling
logic appends CONFIG_CMDLINE to the bootloader provided command line.
The EFI stub does the opposite, and parses the builtin one first.
The usual behavior of command line options is that the last one takes
precedence if it appears multiple times, unless there is a meaningful
way to combine them. In either case, parsing the builtin command line
first while the core kernel does it in the opposite order is likely to
produce inconsistent results in such cases.
Therefore, switch the order in the stub to match the core kernel.

Kexec bypasses EFI's switch to virtual mode. In exchange, it has its own
routine, kexec_enter_virtual_mode(), which replays the mappings made by
the original kernel. Unfortunately, that function fails to reinstate
EFI's memory attributes, which would've otherwise been set after
entering virtual mode. Remediate this by calling
efi_runtime_update_mappings() within kexec's routine.

Drop support for the EFI_PROPERTIES_TABLE. It was a failed, short-lived
experiment that broke the boot both on Linux and Windows, and was
replaced by the EFI_MEMORY_ATTRIBUTES_TABLE shortly after.

There are reports [0] of cases where a corrupt EFI Memory Attributes
Table leads to out of memory issues at boot because the descriptor size
and entry count in the table header are still used to reserve the entire
table in memory, even though the resulting region is gigabytes in size.
Given that the EFI Memory Attributes Table is supposed to carry up to 3
entries for each EfiRuntimeServicesCode region in the EFI memory map,
and given that there is no reason for the descriptor size used in the
table to exceed the one used in the EFI memory map, 3x the size of the
entire EFI memory map is a reasonable upper bound for the size of this
table. This means that sizes exceeding that are highly likely to be
based on corrupted data, and the table should just be ignored instead.

cmdline_ptr is an out parameter, which is not allocated by the function
itself, and likely points into the caller's stack.
cmdline refers to the pool allocation that should be freed when cleaning
up after a failure, so pass this instead to free_pool().

A prior bugfix that fixes a signed/unsigned error causes
another signed unsigned error.
A situation where log_tbl->size is invalid can cause the
size passed to memblock_reserve to become negative.
log_size from the main event log is an unsigned int, and
the code reduces to the following
u64 value = (int)unsigned_value;
This results in sign extension, and the value sent to
memblock_reserve becomes effectively negative.

efi_convert_cmdline() always sets cmdline_size to at least 1 on success,
so the "cmdline_size > 0" does nothing and can be removed (the intent
was to avoid parsing an empty string, but there is nothing wrong with
parsing an empty string, it is only making boot negligibly slower).
Then the cmd_line_len argument to efi_convert_cmdline can be removed
because there is nothing left using it.

efi_convert_cmdline() always returns a size of at least 1 because it
counts the NUL terminator, so the "cmdline_size == 0" condition is never
satisfied.
Change it to check if the string starts with a NUL character to get the
intended behavior: to use CONFIG_CMDLINE when load_options_size == 0.

Fix rcuog kthread wakeup invocation from softirq context on a CPU
which has been marked offline. This can happen when new callbacks
are enqueued from a softirq on an offline CPU before it calls
rcutree_report_cpu_dead(). When this happens on NOCB configuration,
the rcuog wake-up is deferred through an IPI to an online CPU.
This is done to avoid call into the scheduler which can risk
arming the RT-bandwidth after hrtimers have been migrated out
and disabled. However, doing IPI call from softirq is not allowed
Fix this by forcing deferred rcuog wakeup through the NOCB timer
when the CPU is offline.

In that order. Create a test to test this two to make sure this does not
come back as a regression.

- Do not have boot-mapped buffers use CPU hotplug callbacks
When a ring buffer is mapped to memory assigned at boot, it
also splits it up evenly between the possible CPUs. But the
allocation code still attached a CPU notifier callback to this
ring buffer. When a CPU is added, the callback will happen and
another per-cpu buffer is created for the ring buffer. But for
boot mapped buffers, there is no room to add another one (as
they were all created already). The result of calling the CPU
hotplug notifier on a boot mapped ring buffer is unpredictable
and could lead to a system crash. If the ring buffer is boot mapped
simply do not attach the CPU notifier to it.

A root node is required to apply DT overlays. A root node is usually
present after commit 7b937cc243 ("of: Create of_root if no dtb
provided by firmware"), except for on arm64 systems booted with ACPI
tables. In that case, the root node is intentionally not populated
because it would "allow DT devices to be instantiated atop an ACPI base
system"[1].
Introduce an OF function that skips the kunit test if the root node
isn't populated. Limit the test to when both CONFIG_ARM64 and
CONFIG_ACPI are set, because otherwise the lack of a root node is a bug.
Make the function private and take a kunit test parameter so that it
can't be abused to test for the presence of the root node in non-test
code.
Use this function to skip tests that require the root node. Currently
that's the DT tests and any tests that apply overlays.

After a CPU has set itself offline and before it eventually calls
rcutree_report_cpu_dead(), there are still opportunities for callbacks
to be enqueued, for example from a softirq. When that happens on NOCB,
the rcuog wake-up is deferred through an IPI to an online CPU in order
not to call into the scheduler and risk arming the RT-bandwidth after
hrtimers have been migrated out and disabled.
But performing a synchronized IPI from a softirq is buggy as reported in
the following scenario:
WARNING: CPU: 1 PID: 26 at kernel/smp.c:633 smp_call_function_single
Modules linked in: rcutorture torture
CPU: 1 UID: 0 PID: 26 Comm: migration/1 Not tainted 6.11.0-rc1-00012-g9139f93209d1 #1
Stopper: multi_cpu_stop+0x0/0x320 <- __stop_cpus+0xd0/0x120
RIP: 0010:smp_call_function_single

</IRQ>
Fix this with forcing deferred rcuog wake up through the NOCB timer when
the CPU is offline. The actual wake up will happen from
rcutree_report_cpu_dead().

====================
MAINTAINERS: Networking file coverage updates
The aim of this proposal is to make the handling of some files,
related to Networking and Wireless, more consistently. It does so by:
1. Adding some more headers to the UDP section, making it consistent
with the TCP section.
2. Excluding some files relating to Wireless from NETWORKING [GENERAL],
making their handling consistent with other files related to
Wireless.
The aim of this is to make things more consistent. And for MAINTAINERS
to better reflect the situation on the ground. I am more than happy to
be told that the current state of affairs is fine. Or for other ideas to
be discussed.
