linux: Add support for PR_SET_VMA to prctl(2)
Implement dummy support for PR_SET_VMA with PR_SET_VMA_ANON_NAME in
prctl(2). This prevents applications from receiving EINVAL when
attempting to name anonymous memory regions.
bsd.sys.mk: also suppress gcc -Wc++1[47]-extensions warnings for >= 12
This is a direct commit to stable/14, which does not yet default to
C++17 for most in-tree programs. In some cases, this would trigger gcc
-Wc++1[47]-extensions warnings with libc++ 21.
mdmfs: Use standard bool definition
Include `<stdbool.h>` instead of defining a local bool enum.
This avoids duplicating a standard type name and keeps the
source compatible with headers that provide bool as a macro,
or in case of C23 that compilers provide it as keyword.

rpcsvc: Remove obsolete bool definition from yp_prot.h
`yp_prot.h` has carried a SunRPC-era typedef of `bool` guarded by
`BOOL_DEFINED`, but the header itself does not use it. The YP/RPC
interfaces use `bool_t` for protocol booleans.
Defining `bool` in a public header collides with modern C headers
that provide `bool` as a macro or keyword, such as `<stdbool.h>`
and C23-aware assert handling. Drop the compatibility typedef and
leave `bool` definition to the consumer's language mode.

edk2: enable static asserts for *INT64 alignment
The ia32 loader is now built with -malign-double, so these should pass.

stand: compile ia32 EFI loader with -malign-double
The UEFI spec says:
> Structures are aligned on boundaries equal to the largest internal
> datum of the structure and internal data are implicitly padded to
> achieve natural alignment.
Unlike the old Intel EFI toolkit, the EDK2 headers expect ia32 builds to
use -malign-double to achive this.
Make EFI versions of libsa32, liblua32, and ficl32. With the difference
being that they are compiled with -malign-double.

netlink/route: extend pre-2.6.19 Linux compat shim to del/getroute
Commit f34aca55adef ("netlink/route: provide pre-2.6.19 Linux compat shim",
2024-06) fixed the partial fix for net/bird2 on the netlink path by mapping the
legacy 8-bit struct rtmsg::rtm_table field onto the modern 32-bit RTA_TABLE
attribute when the latter is absent.
That fix, however, was only applied to rtnl_handle_newroute. The two sibling
handlers: rtnl_handle_delroute and rtnl_handle_getroute were left looking at
attrs.rta_table directly. They are reachable from exactly the same client
(bird, in its netlink scan path), so any FIB number that fits in 8 bits
silently maps to RT_TABLE_UNSPEC in those handlers.

tools/test/stress2/misc: Fix and enable new tests
The previously committed versions of these tests failed to prevent
duplicate file names in the list of files to process, leading to
missing files when a "mv" commando tried to operate on a file that
had already been renamed.
The test for filenames containing UTF-16 surrogate pairs stays
disabled, since the required kernel changes have not been committed,
yet.
Work around unterminated-string-initialization warnings in acpidb
ACPICA 20250807 fixes these warnings by adding nonstring attributes, but

suppress the warning for clang >= 21 instead. Direct commit to
stable/14, since stable/15 and main already have ACPICA 20250807.

[libc++] Fix iostream size ABI break (#185839)
In #124103 we changed the size of various iostream objects, which turns
out to be ABI breaking when compiling non-PIE code.
This ABI break is safe to fix, since for any programs allocating more
memory for the iostream objects, the remaining bytes are simply unused
now.
Fixes #185724
This fixes the ABI break that causes programs that use the standard
streams to terminate in various interesting ways, usually by throwing an
unexpected std::bad_cast exception.

Thread Safety Analysis: Fix pointer handling of variables with deprecated attributes (#148974)
de10e44b6fe7 ("Thread Safety Analysis: Support warning on
passing/returning pointers to guarded variables") added checks for
passing pointer to guarded variables. While new features do not
necessarily need to support the deprecated attributes (`guarded_var`,
and `pt_guarded_var`), we need to ensure that such features do not cause
the compiler to crash.
As such, code such as this:
struct {
int v __attribute__((guarded_var));
} p;
int *g() {
return &p.v; // handleNoMutexHeld() with POK_ReturnPointer
