Avoid race between process wakeup and tpacket_v3 block timeout.
The test waits for cfg_timeout_msec for packets to arrive. Packets
arrive in tpacket_v3 rings, which pass packets ("frames") to the
process in batches ("blocks"). The sk waits for req3.tp_retire_blk_tov
msec to release a block.
Set the block timeout lower than the process waiting time, else
the process may find that no block has been released by the time it
scans the socket list. Convert to a ring of more than one, smaller,
blocks with shorter timeouts. Blocks must be page aligned, so >= 64KB.

There are some issues with the bpf/nat6to4.c building.
1. It use TEST_CUSTOM_PROGS, which will add the nat6to4.o to
kselftest-list file and run by common run_tests.
2. When building the test via `make -C tools/testing/selftests/
TARGETS="net"`, the nat6to4.o will be build in selftests/net/bpf/
folder. But in test udpgro_frglist.sh it refers to ../bpf/nat6to4.o.
The correct path should be ./bpf/nat6to4.o.
3. If building the test via `make -C tools/testing/selftests/ TARGETS="net"
install`. The nat6to4.o will be installed to kselftest_install/net/
folder. Then the udpgro_frglist.sh should refer to ./nat6to4.o.
To fix the confusing test path, let's just move the nat6to4.c to net folder
and build it as TEST_GEN_FILES.

Currently, anonymous PTE-mapped THPs cannot be collapsed in-place:
collapsing (e.g., via MADV_COLLAPSE) implies allocating a fresh THP and
mapping that new THP via a PMD: as it's a fresh anon THP, it will get the
exclusive flag set on the head page and everybody is happy.
However, if the kernel would ever support in-place collapse of anonymous
THPs (replacing a page table mapping each sub-page of a THP via PTEs with
a single PMD mapping the complete THP), exclusivity information stored for
each sub-page would have to be collapsed accordingly:
(1) All PTEs map !exclusive anon sub-pages: the in-place collapsed THP
must not not have the exclusive flag set on the head page mapped by
the PMD. This is the easiest case to handle ("simply don't set any
exclusive flags").
(2) All PTEs map exclusive anon sub-pages: when collapsing, we have to
clear the exclusive flag from all tail pages and only leave the
exclusive flag set for the head page. Otherwise, fork() after
collapse would not clear the exclusive flags from the tail pages
and we'd be in trouble once PTE-mapping the shared THP when writing
to shared tail pages that still have the exclusive flag set. This
would effectively revert what the PTE-mapping code does when
propagating the exclusive flag to all sub-pages.
(3) PTEs map a mixture of exclusive and !exclusive anon sub-pages (can
happen e.g., due to MADV_DONTFORK before fork()). We must not
collapse the THP in-place, otherwise bad things may happen:
the exclusive flags of sub-pages would get ignored and the
exclusive flag of the head page would get used instead.
Now that we have MADV_COLLAPSE in place to trigger collapsing a THP, let's
add some test cases that would bail out early, if we'd
voluntarily/accidantially unlock in-place collapse for anon THPs and
forget about taking proper care of exclusive flags.
Running the test on a kernel with MADV_COLLAPSE support:
# [INFO] Anonymous THP tests
# [RUN] Basic COW after fork() when collapsing before fork()
ok 169 No leak from parent into child
# [RUN] Basic COW after fork() when collapsing after fork() (fully shared)
ok 170 # SKIP MADV_COLLAPSE failed: Invalid argument
# [RUN] Basic COW after fork() when collapsing after fork() (lower shared)
ok 171 No leak from parent into child
# [RUN] Basic COW after fork() when collapsing after fork() (upper shared)
ok 172 No leak from parent into child
For now, MADV_COLLAPSE always seems to fail if all PTEs map shared
sub-pages.

Preallocations are common in the VMA code to avoid allocating under
certain locking conditions. The preallocations must also cover the
worst-case scenario. Removing the GFP_ZERO flag from the
kmem_cache_alloc() (and bulk variant) calls will reduce the amount of time
spent zeroing memory that may not be used. Only zero out the necessary
area to keep track of the allocations in the maple state. Zero the entire
node prior to using it in the tree.
This required internal changes to node counting on allocation, so the test
code is also updated.

Convert to struct mnt_idmap.
Last cycle we merged the necessary infrastructure in
256c8aed2b ("fs: introduce dedicated idmap type for mounts").
This is just the conversion to struct mnt_idmap.
Currently we still pass around the plain namespace that was attached to a
mount. This is in general pretty convenient but it makes it easy to
conflate namespaces that are relevant on the filesystem with namespaces
that are relevent on the mount level. Especially for non-vfs developers
without detailed knowledge in this area this can be a potential source for
bugs.
Once the conversion to struct mnt_idmap is done all helpers down to the
really low-level helpers will take a struct mnt_idmap argument instead of
two namespace arguments. This way it becomes impossible to conflate the two
eliminating the possibility of any bugs. All of the vfs and all filesystems
only operate on struct mnt_idmap.

Pull memblock fix from Mike Rapoport:
"memblock: always release pages to the buddy allocator in
memblock_free_late()
If CONFIG_DEFERRED_STRUCT_PAGE_INIT is enabled, memblock_free_pages()
only releases pages to the buddy allocator if they are not in the
deferred range. This is correct for free pages (as defined by
for_each_free_mem_pfn_range_in_zone()) because free pages in the
deferred range will be initialized and released as part of the
deferred init process.
memblock_free_pages() is called by memblock_free_late(), which is used
to free reserved ranges after memblock_free_all() has run. All pages
in reserved ranges have been initialized at that point, and
accordingly, those pages are not touched by the deferred init process.
This means that currently, if the pages that memblock_free_late()
intends to release are in the deferred range, they will never be
released to the buddy allocator. They will forever be reserved.
In addition, memblock_free_pages() calls kmsan_memblock_free_pages(),
which is also correct for free pages but is not correct for reserved
pages. KMSAN metadata for reserved pages is initialized by
kmsan_init_shadow(), which runs shortly before memblock_free_all().
For both of these reasons, memblock_free_pages() should only be called
for free pages, and memblock_free_late() should call
__free_pages_core() directly instead.
One case where this issue can occur in the wild is EFI boot on x86_64.
The x86 EFI code reserves all EFI boot services memory ranges via
memblock_reserve() and frees them later via memblock_free_late()
(efi_reserve_boot_services() and efi_free_boot_services(),
respectively).
If any of those ranges happens to fall within the deferred init range,
the pages will not be released and that memory will be unavailable.
For example, on an Amazon EC2 t3.micro VM (1 GB) booting via EFI:
v6.2-rc2:
Node 0, zone DMA

The BTI selftests are built both with and without BTI support, validating
both the generation of BTI signals as expected for binaries without BTI
support. Both versions of the binary currently skip all their tests when
the system does not support BTI, however this is excessive since we do have
a defined ABI for how the programs should function in this case (especially
for the non-BTI binary). Update the test program to run all the tests
unconditionally, adding a runtime adjustment of the expected results on
systems that don't support BTI where we currently handle the build time
case.
The tests all use HINT space instructions, BTI itself is a HINT as is
are the PAC instructions that function as landing pads, so nothing in the
tests depends on support for BTI in the kernel or hardware.

Since virtual implementations are noticeably slow in general and the larger
vector lengths amplify the issue there's a useful improvement in runtime
from only covering the vector lengths that will exist in practical systems,
adjust our enumeration accordingly. We have other tests that aim to cover
the enumeration interfaces.
For symmetry we apply the same change to the eumeration for SME vector
lengths, though the power of two restriction was already present for SME
so there is no impact on the set of vector lengths tested.

Currently syscall-abi only covers SME in the case where the system supports

check for SVCR.SM being set when deciding if we're handling the FPSIMD or
SVE registers and the addition of new test cases for the SME only case.
Note that in the SME only case we should not save the SVE registers after a
syscall since even if we were in streaming mode and therefore set them the
syscall should have exited streaming mode, we check that we have done so by
looking at SVCR.

only has to say what XDP program it needs if it is not the default
one. This also makes it possible to remove the initial explicit
attachment of the XDP program as well as the explicit mode switch in
the code. These are now handled by the same code that just checks if a
switch is necessary, so no special cases are needed.
The default XDP program for all tests is one that sends all packets to
