drm/amdkfd: drop struct kfd_signal_page wrapper

Browse source

struct kfd_signal_page now only wraps a single uint64_t *kernel_address
pointer. Drop the wrapper struct (and the page_slots() helper) and store
the signal page pointer directly in kfd_process::signal_page.

Since the signal page is the GTT BO mapping provided by user mode and is
not owned by the events code, no separate allocation/free is needed for
it, so shutdown_signal_page() goes away as well.

No functional change intended.
