[Allocator] Cap MinAlign at alignof(max_align_t) (#235373)
alignof(std::max_align_t) is 4 on NetBSD/i386, whose <stddef.h> defines
max_align_t as a union of void *, long double, and long long.
Fix #230782
share/mk/bsd.confs.mk: fix trivial typo in message
The error message noting that the file should not be included said
"bsd.conf.mk" before this change. Now it correctly says "bsd.confs.mk".

[BPF] Disambiguate CO-RE relocation globals (#234252)
The BPF backend encodes the relocation kind, local value and access path
in a global name. Type names such as `S<ns::Arg$>` can contain both
delimiters. Decode the fixed suffix from the right in instruction
folding and BTF emission. This fixes the compiler crash reported in
#233947.
Within a module, different debug types can produce the same name. A
pointer access and a 32-bit field-offset query can also have the same
name with different load types. Reuse an external relocation global only
when its debug root and load type match. Put any discriminator before
the suffix so both consumers read the original relocation.

[libunwind] Support extended amd64 segment registers (#229176)
Raise the amd64 DWARF register limit to 59 and add RFLAGS, all six
segment selectors, FS.base, and GS.base to the register model. Capture
the extended state and restore it when resuming, using sigreturn() on
FreeBSD to restore selectors and bases together. Pack the state into the
existing context buffers without changing their public sizes or the
Windows XMM offsets.
Add tests for register access, signal-frame CFI recovery, register
bounds, and resume behavior.

[lldb][bazel] Add targets for the remaining unconditional plugins (#235325)
CMake builds these plugins on every host, but the Bazel overlay had no
targets for them:
- PluginABILoongArch
- PluginDynamicLoaderFreeBSDKernel
- PluginPlatformAIX
- PluginPlatformFreeBSD
- PluginPlatformNetBSD
- PluginPlatformOpenBSD
- PluginTypeSystemClike
I also added these to the DEFAULT_PLUGINS list.
For now, I'm still leaving out plugins that CMake only builds with an
optional dependency or on a specific host:
- ProcessFreeBSDKernelCore (FreeBSD hosts, libkvm)

"Here is the big set of char/misc/android/iio and other small driver
subsystem patches for 7.4-rc1. Loads of stuff in here, larger than
normal. Highlights include:
- removal of the C binder code, the rust version is stable and will
be used going forward in a few billion devices. Great job by those
developers
- loads and loads of IIO driver updates and feature additions
- speakup driver fixes and updates
- mhi driver updates

Update devel/ocaml-ppxlib to version 0.33.0.
0.33.0 (2024-07-22)
-------------------
- Fix a bug where `Code_path.main_module_name` would not properly remove
extensions from the filename and therefore return an invalid module name.
(#512, @NathanReb)
- Add `-unused-type-warnings` flag to the driver to allow users to disable
only the generation of warning 34 silencing structure items when using
`[@@deriving ...]` on type declarations. (#511, @mbarbin, @NathanReb)
- Make `-unused-code-warnings` flag to the driver also controls the generation
of warning 34 silencing structure items when using `[@@deriving ...]` on type
declarations. (#510, @mbarbin, @NathanReb)
- Driver: Add `-unused-code-warnings=force` command-line flag argument. (#490, @mbarbin)

[MemorySSA] Remove unused functions (NFC) (#235374)
Remove MemoryPhi::unorderedDeleteIncomingValue, upward_defs and
ClobberWalker::const_def_path, which have no callers, together with the
const_def_path_iterator alias only used by const_def_path.
Merge tag 'tty-7.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty
Pull tty / serial driver updates from Greg KH:
"Here is the "big" set of tty and serial driver updates for 7.4-rc1.
It's not really all that big, it's been kind of quiet in this area of
the tree this development cycle in relation to other parts of the
tree. But still, included in here are:
- 8250 port updates and fixes
- 8250 driver cleanups by Jiri
- deletion of the obsolete moxa driver (making this pull request
remove more lines than added!)
- different serial driver updates for dma and other reported issues
All of these have been in linux-next with no reported problems"

Build minivmac with -fno-strict-overflow to fix a crash on macppc.
Patch the port to use CC and CFLAGS and not strip(1). Build
DEBUG_PACKAGES. Put myself as MAINTAINER.
A pointer might have wrapped around NULL, which is undefined behavior
in C. clang-local(1) -wrapv stopped affecting pointers when we
updated clang from 19 to 22.

Merge tag 'staging-7.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging
Pull staging driver updates from Greg KH:
"Here is the big set of staging driver updates for 7.4-rc1.
The huge majority of changes in here were to the rtl8723bs driver,
which ended up being deleted entirely through the wifi driver tree, so
while the work here was nice to have done to get experience by people,
the overall goal was achieved in that we have a solid working and sane
driver in the real part of the tree now.
Other than that, included in here are:
- some greybus driver removal of broken drivers that no one ever used
- minor coding style cleanups for other staging drivers
All of these have been in linux-next with no reported issues, other
than the merge conflict of the driver being removed, but that's an
obvious one to resolve :)"

[LAA] Avoid division by zero for zero-sized access types. (#235372)
Zero-sized access types lead to divide-by-zero in getStrideFromAddRec.
Bail out if that would be the case.
[libunwind] Unwind through AArch64 FreeBSD signal trampolines (#235065)
Retried from https://reviews.llvm.org/D155066.
Recognize signal trampolines using KERN_PROC_SIGTRAMP when unwind
metadata is unavailable. Restore the interrupted PC, LR, SP, general
registers, and valid floating-point registers.
Add coverage for unwinding out of an interrupted leaf function on both
regular and alternate signal stacks.
