vgsp-sema: log release writes into the UVM sysmem semaphore range (ISSUE-0002 diagnosis)
Bounded instrumentation: every svc_sem_write into 0x7924_xxxx_xxxx..0x7926
records (h, va, pa, aperture, resolver provenance, value, write rc,
read-back ok/value, pool) so the second session's translations for the
same VAs can be compared against the first session's. The second client
spins in uvm_gpu_retain_by_uuid -> uvm_page_tree_init ->
uvm_push_end_and_wait -> wait_for_entry_with_spin (guest kernel stack,
sysrq-l) waiting on the channel tracking semaphore; these lines will
name the PA the release landed at.
