sparc64: Fix race in arch/sparc64/kernel/trampoline.S
[ Upstream commit e0037df3852b4b60edbe01f70f4968e4a9fdb272 ]
Make arch/sparc64/kernel/trampoline.S in 2.6.27.1 lock prom_entry_lock
when calling the PROM. This prevents a race condition that I observed
causing a hang on startup on a 12-CPU E4500.
