If you attempt to build or install modules ('make modules(_install)'
with CONFIG_MODULES disabled, you will get a clear error message, but
nothing for external module builds.
Factor out the modules and modules_install rules into the common part,
so you will get the same error message when you try to build external

- `configure` command line values if both `--with-linux` and
`--with-linux-obj` were defined
- If only `--with-linux` was defined, `--with-linux-obj` is assumed
to have the same value as `--with-linux`
- If neither `--with-linux` nor `--with-linux-obj` were defined
autodetection is used:
- `/lib/modules/$(uname -r)/{source,build}` respectively, if exist
- The first directory in `/lib/modules` with the highest version
number according to `sort -V` which contains `source` and `build`
symlinks/directories
- The first directory matching `/usr/src/kernels/*` and
`/usr/src/linux-*` with the highest version number according to
`sort -V`. Here the source and prebuilt directories are assumed

Currently, $(CC), $(LD), and $(LLVM) variables aren't passed to kbuild

GNU GCC toolchain and prevents experimenting with other toolchains such
as CLANG/LLVM. It can also lead to build failure if the CFLAGS/LDFLAGS
passed are incompatible with gcc/ld.
Pass $KERNEL_CC, $KERNEL_LD, and $KERNEL_LLVM as $(CC), $(LD), and

environment. This should take care of the majority of alternative

Linux 5.16 moved XSTATE_XSAVE and XSTATE_XRESTORE out of our reach,
so add our own XSAVE{,OPT,S} code and use it for Linux 5.16.
Please note that this differs from previous behavior in that it
won't handle exceptions created by XSAVE an XRSTOR. This is sensible
for three reasons.
- Exceptions during XSAVE and XRSTOR can only occur if the feature
is not supported or enabled or the memory operand isn't aligned
on a 64 byte boundary. If this happens something else went
terribly wrong, and it may be better to stop execution.
- Previously we just printed a warning and didn't handle the fault,
this is arguable for the above reason.
- All other *SAVE instruction also don't handle exceptions, so this
at least aligns behavior.
Finally add a test to catch such a regression in the future.

This change also creates a new vdev_bio_set_dev() function that performs
