userspace/cuda: analysis note for the cuCtxCreate segfault (gdb trace)
Documents the exact crash: cuInit/device enumeration now succeed; cuCtxCreate
faults in an engine-check/report path at libcuda+0x453f90 with rbp=0.
Register trace shows rbp valid at the helper and at the dispatch hook's
leave, but 0 immediately after the hook returns; the hook and the dispatch
table entries are all valid libcuda code. Adds the ioctl sequence observed
before the crash and lists what is still unanalysed.
