LinuxKPi: idr: use macros for lock idr lock operations
Our idr implementation is using a mtx lock which in the past has
already caused problems (613723bac219c).
In order to make it easier to tackle the problem start by factoring
out all the operations related to the idr->lock into macros as we
have often done in other parts of code as well.

LinuxKPI: 802.11 suspend/resume: fix the is_pci_dev check
Shortly before I committed the works from a year ago, jhb added a
function ("is_pci_device") so that the check against the devclass
does not have to be coded in every driver. Use this instead in main
(and stable/15 in case the works get MFCed).
At the same time this fixes the check (the old one was wrong) as we
attach to the LinuxKPI 802.11 driver, e.g., iwlwifi and thus we need
to check the parent of the parent and not just the parent to be
of the devclass "pci" in the identify bus function. The was the
first error. The second was (and this is why it worked) that we
checked for == instead of != and so the wrong check became true again.

rtwn/usb: add ID for D-Link DWA-121 rev B1 to rtwn RTL8188EU
Add the device ID to the usbdevs table in order to be able to use

linux: Add support for PR_SET_VMA to prctl(2)

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

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,

[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.
