This function does not build on 32-bit targets when the compiler
fails to reduce DIV_ROUND_UP() into a shift:
ld.lld: error: undefined symbol: __aeabi_uldivmod
>>> referenced by xe_migrate.c
>>> drivers/gpu/drm/xe/xe_migrate.o:(pte_update_size) in archive vmlinux.a
There are two instances in this function. Change the first to
use an open-coded shift with the same behavior, and the second
one to a 32-bit calculation, which is sufficient here as the size
is never more than 2^32 pages (16TB).

When the driver is built-in but the tests are in loadable modules,
the helpers don't actually get put into the driver:
ERROR: modpost: "xe_kunit_helper_alloc_xe_device" [drivers/gpu/drm/xe/tests/xe_test.ko] undefined!
Change the Makefile to ensure they are always part of the driver
even when the rest of the kunit tests are in loadable modules.

Since we cannot immediately capture the BO's and userptr, perform it in
2 stages. The immediate stage takes a reference to each BO and userptr,
while a delayed worker captures the contents and then frees the
reference.
This is required because in signaling context, no locks can be taken, no
memory can be allocated, and no waits on userspace can be performed.
With the delayed worker, all of this can be performed very easily,
without having to resort to hacks.
Changes since v1:
- Fix crash on NULL captured vm.
- Use ascii85_encode to capture BO contents and save some space.
- Add length to coredump output for each captured area.
Changes since v2:
- Dump each mapping on their own line, to simplify tooling.
- Fix null pointer deref in xe_vm_snapshot_free.
Changes since v3:
- Don't add uninitialized value to snap->ofs. (Souza)
- Use kernel types for u32 and u64.
- Move snap_mutex destruction to final vm destruction. (Souza)
Changes since v4:
- Remove extra memset. (Souza)
