The kbuild robot reports that we're relying on an implicit inclusion to
get a definition of task_stack_page() in the Spectre-v4 mitigation code,
which is not always in place for some configurations:
| arch/arm64/kernel/proton-pack.c:329:2: error: implicit declaration of function 'task_stack_page' [-Werror,-Wimplicit-function-declaration]
| task_pt_regs(task)->pstate |= val;
| ^
| arch/arm64/include/asm/processor.h:268:36: note: expanded from macro 'task_pt_regs'
| ((struct pt_regs *)(THREAD_SIZE + task_stack_page(p)) - 1)
| ^
| arch/arm64/kernel/proton-pack.c:329:2: note: did you mean 'task_spread_page'?
Add the missing include to fix the build error.
Fixes: a44acf477220 ("arm64: Move SSBD prctl() handler alongside other spectre mitigation code")
