Instead of allocating and copying instruction history each time we
enqueue child verifier state, switch to a model where we use one common
dynamically sized array of instruction history entries across all states.
The key observation for proving this is correct is that instruction
history is only relevant while state is active, which means it either is
a current state (and thus we are actively modifying instruction history
and no other state can interfere with us) or we are checkpointed state
with some children still active (either enqueued or being current).
In the latter case our portion of instruction history is finalized and
won't change or grow, so as long as we keep it immutable until the state
is finalized, we are good.
Now, when state is finalized and is put into state hash for potentially
future pruning lookups, instruction history is not used anymore. This is
because instruction history is only used by precision marking logic, and
we never modify precision markings for finalized states.
So, instead of each state having its own small instruction history, we
keep a global dynamically-sized instruction history, where each state in
current DFS path from root to active state remembers its portion of
instruction history. Current state can append to this history, but
cannot modify any of its parent histories.
Async callback state enqueueing, while logically detached from parent
state, still is part of verification backtracking tree, so has to follow
the same schema as normal state checkpoints.
Because the insn_hist array can be grown through realloc, states don't
keep pointers, they instead maintain two indices, [start, end), into
global instruction history array. End is exclusive index, so
`start == end` means there is no relevant instruction history.
This eliminates a lot of allocations and minimizes overall memory usage.
For instance, running a worst-case test from [0] (but without the
heuristics-based fix [1]), it took 12.5 minutes until we get -ENOMEM.
With the changes in this patch the whole test succeeds in 10 minutes
(very slow, so heuristics from [1] is important, of course).
To further validate correctness, veristat-based comparison was performed for
Meta production BPF objects and BPF selftests objects. In both cases there
were no differences *at all* in terms of verdict or instruction and state
counts, providing a good confidence in the change.
Having this low-memory-overhead solution of keeping dynamic
per-instruction history cheaply opens up some new possibilities, like
keeping extra information for literally every single validated
instruction. This will be used for simplifying precision backpropagation
logic in follow up patches.

Regions will serve multiple purposes. First, with it we can decouple
ring/etc. object creation from registration / mapping of the memory they
will be placed in. We already have hacks that allow to put both SQ and
CQ into the same huge page, in the future we should be able to:
region = create_region(io_ring);
create_pbuf_ring(io_uring, region, offset=0);
create_pbuf_ring(io_uring, region, offset=N);
The second use case is efficiently passing parameters. The following
patch enables back on top of regions IORING_ENTER_EXT_ARG_REG, which
optimises wait arguments. It'll also be useful for request arguments
replacing iovecs, msghdr, etc. pointers. Eventually it would also be
handy for BPF as well if it comes to fruition.

We've got a good number of mappings we share with the userspace, that
includes the main rings, provided buffer rings, upcoming rings for
zerocopy rx and more. All of them duplicate user argument parsing and
some internal details as well (page pinnning, huge page optimisations,
mmap'ing, etc.)
Introduce a notion of regions. For userspace for now it's just a new
structure called struct io_uring_region_desc which is supposed to
parameterise all such mapping / queue creations. A region either
represents a user provided chunk of memory, in which case the user_addr
field should point to it, or a request for the kernel to allocate the
memory, in which case the user would need to mmap it after using the
offset returned in the mmap_offset field. With a uniform userspace API
we can avoid additional boiler plate code and apply future optimisation
to all of them at once.
Internally, there is a new structure struct io_mapped_region holding all
relevant runtime information and some helpers to work with it. This
patch limits it to user provided regions.

For unbound workqueue, pwqs usually map to just a few pools. Most of
the time, pwqs will be linked sequentially to wq->pwqs list by cpu
index. Usually, consecutive CPUs have the same workqueue attribute
(e.g. belong to the same NUMA node). This makes pwqs with the same
pool cluster together in the pwq list.
Only do lock/unlock if the pool has changed in flush_workqueue_prep_pwqs().
This reduces the number of expensive lock operations.
The performance data shows this change boosts FIO by 65x in some cases
when multiple concurrent threads write to xfs mount points with fsync.

- FIO version: v3.35
- FIO Options: ioengine=libaio,iodepth=64,norandommap=1,rw=write,

- FIO Job Configs: 64 jobs in total writing to 4 mount points (ramdisks
formatted as xfs file system).
- Kernel Codebase: v6.12-rc5
- Test Platform: Xeon 8380 (2 sockets)

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.

The CRC-T10DIF algorithm produces a 16-bit CRC, and this is reflected in
the folding coefficients, which are also only 16 bits wide.
This means that the polynomial multiplications involving these
coefficients can be performed using 8-bit long polynomial multiplication
(8x8 -> 16) in only a few steps, and this is an instruction that is part
of the base NEON ISA, which is all most real ARMv7 cores implement. (The
64-bit PMULL instruction is part of the crypto extensions, which are
only implemented by 64-bit cores)
The final reduction is a bit more involved, but we can delegate that to
the generic CRC-T10DIF implementation after folding the entire input
into a 16 byte vector.
This results in a speedup of around 6.6x on Cortex-A72 running in 32-bit
mode. On Cortex-A8 (BeagleBone White), the results are substantially
better than that, but not sufficiently reproducible (with tcrypt) to
quote a number here.

The only remaining user of the fallback implementation of 64x64
polynomial multiplication using 8x8 PMULL instructions is the final
reduction from a 16 byte vector to a 16-bit CRC.
The fallback code is complicated and messy, and this reduction has
little impact on the overall performance, so instead, let's calculate
the final CRC by passing the 16 byte vector to the generic CRC-T10DIF
implementation when running the fallback version.

The CRC-T10DIF implementation for arm64 has a version that uses 8x8
polynomial multiplication, for cores that lack the crypto extensions,
which cover the 64x64 polynomial multiplication instruction that the
algorithm was built around.
This fallback version rather naively adopted the 64x64 polynomial
multiplication algorithm that I ported from ARM for the GHASH driver,
which needs 8 PMULL8 instructions to implement one PMULL64. This is
reasonable, given that each 8-bit vector element needs to be multiplied
with each element in the other vector, producing 8 vectors with partial
results that need to be combined to yield the correct result.
However, most PMULL64 invocations in the CRC-T10DIF code involve
multiplication by a pair of 16-bit folding coefficients, and so all the
partial results from higher order bytes will be zero, and there is no
need to calculate them to begin with.
Then, the CRC-T10DIF algorithm always XORs the output values of the
PMULL64 instructions being issued in pairs, and so there is no need to
faithfully implement each individual PMULL64 instruction, as long as
XORing the results pairwise produces the expected result.
Implementing these improvements results in a speedup of 3.3x on low-end
platforms such as Raspberry Pi 4 (Cortex-A72)

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.
