[CodeGen] De-type getMinimalPhysRegClass and related APIs (#197495)
Follow-up #193438 to de-type getMinimalPhysRegClass so it can be replaced with
the precomputed getDefaultMinimalPhysRegClass. Type is also removed from
related APIs.
There's very few uses of getMinimalPhysRegClass with a non-default type
(MVT::Other) and none at all for getCommonMinimalPhysRegClass. Rather than
trying to also handle the type when precomputing at compile-time it seems
better to remove the type altogether and simplify the APIs. This also improves
compile-time for a number of targets and configurations:

[RISCV] Ensure LPAD alignment for calls to returns_twice functions (#177515)
When Zicfilp is enabled, all LPAD instructions must be 4-byte aligned,
including those following a returns_twice call. Linker relaxation can
convert calls to c.jal (RV32C) or cm.jalt (Zcmt), causing LPAD
misalignment.
This patch handles calls to returns_twice functions (e.g., setjmp) when
Zicfilp CFI is enabled:
1. In ISel (LowerCall), detect
CLI.CB->hasFnAttr(Attribute::ReturnsTwice)
and select LPAD_CALL or LPAD_CALL_INDIRECT ISD opcodes. Custom ISel
in RISCVISelDAGToDAG adds the landing pad label as a pseudo operand.
2. RISCVAsmPrinter::emitLpadAlignedCall handles assembly output: when
Zca
is enabled, emit .p2align 2 before the call. When linker relaxation is
also enabled, wrap with .option push/exact/pop to prevent relaxation.

pf: do not reject rules with colliding hashes
We insert rules in pf_krule_global solely for the benefit of the
'keepcounters' feature. Failing to insert (beause the rule hash
collides, or an identical rule already exists) would be worse than
restoring counts to the wrong rule (or failing to restore them at all).

pfsync: reject invalid SCTP states
SCTP states should always have a src scrub object associated with them.
Crafted pfsync packets might not have this, leading to us derferencing a

routing: Initialize V_rt_numfibs earlier during boot
V_rt_numfibs can be set at compile time (with the ROUTETABLES kernel
config option) or boot time (with the net.fibs tunable).
vnet_rtables_init(), running during SI_PROTO_DOMAIN, was checking the
tunable and updating V_rt_numfibs accordingly, but that means that
earlier SYSINITs, such as vnet_mroute_init(), see the compile-time value
for V_rt_numfibs before it gets corrected in vnet_rtables_init().
Fix this by initializing V_rt_numfibs earlier, so that SYSINITs are less
likely to use the wrong value.
Add a comment describing the weird, preexisting semantic of resetting
rt_numfibs to 1 in VNET jails.

if_vxlan: Update *m0 after a pullup
vxlan_input()'s caller is supposed to free *m0 if it is non-NULL after
the function returns. vxlan_input() failed to update *m0 after the
pullup however, so if it hits an error case after the pullup, we'll free
the mbuf twice. Currently this can happen only if the interface is
brought down or due to a packet loop.

ipfw: fix checksum after NAT
When checksum offloading is used, IPFW needs to fix the checksum
after libalias has done NAT. The ipfw_nat() function does so, but
only for mbufs without a receiving interface. However, if, for example,
the packet was sent inside a jail that used checksum offloading over
an epair, ipfw still needs to fix the checksum even though the mbuf
has set a receiving interface (epair).
This patch just removes the check whether a receiving interface is set.

netmap: silence -Wdefault-const-init-field-unsafe warning
The netmap_ring struct starts with various const members and rencent
clang warns about leaving them uninitialized. Having them const in the
first place is highly suspicious since they are updated with various
macros but using hand-coded __DECONST(). But fixing that is a more
invasive change that I am unable to test.

[X86] Fold OR of constant splats into GF2P8AFFINEQB (#194330)
Fold OR of a constant byte splat into X86ISD::GF2P8AFFINEQB when the
affine matrix is known at compile time.
For bits forced to 1 by the OR mask, zero the corresponding matrix rows
(in reverse row order within each 64-bit lane) and set the same bits in
the immediate. This turns:
gf2p8affineqb(x, M, imm) | C
into:
gf2p8affineqb(x, M & KeepMask, imm | C)
where KeepMask clears the rows for output bits selected by C.
This removes a separate OR after GF2P8AFFINEQB for constant-matrix cases
and extends the existing GFNI combine coverage beyond XOR folds.

py-aiohttp: updated to 3.14.0
3.14.0 (2026-06-01)
Features
- Added ``RequestKey`` and ``ResponseKey`` classes,
which enable static type checking for request & response
context storages in the same way that ``AppKey`` does for ``Application``
- Added :func:`~aiohttp.encode_basic_auth` for encoding HTTP Basic
Authentication credentials. Replaces the now-deprecated
:class:`~aiohttp.BasicAuth`
- Started accepting :term:`asynchronous context managers <asynchronous context manager>` for cleanup contexts.
Legacy single-yield :term:`asynchronous generator` cleanup contexts continue to be
supported; async context managers are adapted internally so they are
entered at startup and exited during cleanup.
- Added :py:attr:`~aiohttp.CookieJar.cookies` and :py:attr:`~aiohttp.CookieJar.host_only_cookies` read-only properties to :py:class:`~aiohttp.CookieJar` exposing the stored cookies with their full attributes
- Added :py:attr:`~aiohttp.web.TCPSite.port` accessor for dynamic port allocations in :class:`~aiohttp.web.TCPSite`
- Added ``decode_text`` parameter to :meth:`~aiohttp.ClientSession.ws_connect` and :class:`~aiohttp.web.WebSocketResponse` to receive WebSocket TEXT messages as raw bytes instead of decoded strings, enabling direct use with high-performance JSON parsers like ``orjson``
