6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Peter Zijlstra peterz@infradead.org
commit 41a1e976623eb430f7b5a8619d3810b44e6235ad upstream.
Commit 2190966fbc14 ("x86: Convert unreachable() to BUG()") missed one.
And after commit 06e24745985c ("objtool: Remove annotate_{,un}reachable()") the invalid use of unreachable() (rightfully) triggers warnings:
vmlinux.o: warning: objtool: page_fault_oops() falls through to next function is_prefetch()
