When doing a fully incremental build (with WITHOUT_CLEAN enabled), from
a commit before llvm 15 was merged (3264f6b88f), to a commit after
that, a number of .inc files were not regenerated. This could lead to
unexpected compilation errors when these .inc files were included from
llvm-project sources, similar to:
In file included from /usr/src/contrib/llvm-project/clang/lib/CodeGen/CGBuiltin.cpp:8268:
/usr/obj/usr/src/amd64.amd64/lib/clang/libclang/clang/Basic/arm_mve_builtin_cg.inc:279:18: error: no matching constructor for initialization of 'clang::CodeGen::Address'
Address Val2 = Address(Val1, CharUnits::fromQuantity(2));
^ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Work around this by making the .inc files dependent on the tblgen binary
used for generating them. E.g., we can relatively safely assume that if
the binary gets updated, the .inc files must also be updated. (Although
this is not 100% optimal, the gain by complicating things even more is
probaby not worth the effort.)

The prior code mistakently thought that the g_consumer that hung off the
provider we found were the right thing to use to find all the glabel
aliases for this node. However, the only way to find that is to iterate
through all the geoms that belong to the glabel geom class, looking for
those geoms with the same name as the provider with the right efimedia.
Do this in a way that caches glabel class, and allows for it to be
absent. Tighten the filter for mounted filesystems to only look
for the ones that are mounted on /dev/.. since the rest of the code
assumes that.

In path_to_dp, allow passing in either the actual device path "eg
/dev/foo/bar" or the path where the device is mounted (say
/mnt/baz/bing). In the former case we'll assume the path within the

If there's no efimedia attribute on the provider, and the provider's a
glabel, then find the 'parent' geom. In this case, the provider's name
is label-type/name, but the geom's label will that of the underlying

the geom's name, which shuold have the efimedia attribute.

Merge commit '755d9301ca89f02956fd17858b9d4d821ab5c972' from the
vendor branch. This updates us from lua 5.4.2 to 5.4.4.
In addition, it switches around how we flavor liblua for the boot loader
and flua. This is done to reduce diffs with upstream and make it easier
to import new versions (the current method has too many conflicts to
resolve by hand): we include luaconf.local.h from luaconf.h (the only
change to this file is now that #include at the end). We then define
what we need to: for flua (which does very little) and one for stand
(which creates the new FLOAT type out of int64).

When __thr_pshared_offpage() is called for allocation, it must not use

It is legitimate for the user code to unmap the shared lock object without
destroying it, and then mapping something over the freed VA to carry
another shared lock. In this case the cached offpage must be un-cached.
