[Hexagon] Fix hasFP to respect frame-pointer attribute unconditionally (#181524)
HexagonFrameLowering::hasFPImpl() incorrectly gated the
DisableFramePointerElim check behind MFI.getStackSize() > 0. This meant
leaf functions with no stack allocation would not get a frame pointer
even when "frame-pointer"="all" (-fno-omit-frame-pointer) was set,
violating the user/ABI request. Every other LLVM target checks
DisableFramePointerElim unconditionally.
Move the DisableFramePointerElim and EliminateFramePointer checks
outside the getStackSize() > 0 guard so they are always evaluated.
Update affected tests whose CHECK patterns change due to the now-
correct allocframe emission.
Revert "[CMake][TableGen] Fix Ninja depslog error with implicit outputs on Ninja <1.10" (#182695)
Reverts llvm/llvm-project#179842
This seems to break some dependency tracking, as I no longer see .inc
files being regenerated when I update a TableGen .cpp file. Reverting
for now per the discussion on the PR.
AMDGPU: Implement expansion for f64 exp
I asked AI to port the device libs reference implementation.
It mostly worked, though it got the compares wrong and also
missed a fold that happened in compiler. With that fixed I get
identical DAG output, and almost the same globalisel output (differing
by an inverted compare and select). Also adjusted some stylistic choices.
don't include CN in the certificate signing request.
the CA will decide whether to include a CN based on their
configuration/profile and sets that up themselves.

InstCombine: Fold out nanless canonicalize pattern
Pattern match a wrapper around llvm.canonicalize which
weakens the semantics to not require quieting signaling
nans. Depending on the denormal mode and FP type, we can
either drop the pattern entirely or reduce it only to
a canonicalize call. I'm inventing this pattern to deal
with LLVM's lax canonicalization model in math library
code.
The math library code currently has explicit checks for
the denormal mode, and conditionally canonicalizes the
result if there is flushing. Semantically, this could be
directly replaced with a simple call to llvm.canonicalize,
but doing so would incur an additional cost when using
standard IEEE behavior. If we do not care about quieting
a signaling nan, this should be a no-op unless the denormal
mode may flush. This will allow replacement of the
conditional code with a zero cost abstraction utility

Merge tag 'kmalloc_obj-treewide-v7.0-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux
Pull kmalloc_obj conversion from Kees Cook:
"This does the tree-wide conversion to kmalloc_obj() and friends using
coccinelle, with a subsequent small manual cleanup of whitespace
alignment that coccinelle does not handle.
This uncovered a clang bug in __builtin_counted_by_ref(), so the
conversion is preceded by disabling that for current versions of
clang. The imminent clang 22.1 release has the fix.
I've done allmodconfig build tests for x86_64, arm64, i386, and arm. I
did defconfig builds for alpha, m68k, mips, parisc, powerpc, riscv,
s390, sparc, sh, arc, csky, xtensa, hexagon, and openrisc"

ECDSA / EC key support for XAdES authentication
Qualified certificates issued by MCU (Ministerstwo Cyfryzacji) use EC keys (secp256r1).
Previously the SDK would raise TypeError: Expected RSA private key, got EllipticCurvePrivateKey
when loading such certificates. This release adds full EC key support alongside the existing RSA path.
Changes:
load_private_key_from_pem now accepts both RSA and EC private keys
load_certificate_and_key_from_p12 now accepts both RSA and EC private keys
sign_xades automatically selects ECDSA-SHA256 for EC keys and RSA-SHA256 for RSA keys — no extra configuration needed
No breaking changes — existing RSA-based code continues to work without modification.

security/zeek: Do not remove state.db on pkg remove
Klemens Nanni reported that "pkg upgrade zeek" was breaking zeekctl
in a cluster installation. Testing showed this was also true for
standalone.
The pkg-message already advises the user that they may need to
manually remove state.db.

InstCombine: Fold absorbing fmul of compared 0 into select (#172381)
This is similar to the select-bin-op identity case, except
in this case we are looking for the absorbing value for the
binary operator.
If the compared value is a floating-point 0, and the fmul is
implied to return a +0, put the 0 directly into the select
operand. This pattern appears in scale-if-denormal sequences
after optimizations assume denormals are treated as 0.
Fold:
```
%fabs.x = call float @llvm.fabs.f32(float %x)
%mul.fabs.x = fmul float %fabs.x, known_positive
%x.is.zero = fcmp oeq float %x, 0.0
%select = select i1 %x.is.zero, float %mul.fabs.x, float %fabs.x
