sparc64: Use LOCKDEP_SMALL, not PROVE_LOCKING_SMALL
CONFIG_PROVE_LOCKING_SMALL shrinks the memory usage of lockdep so the kernel text, data, and bss fit in the required 32MB limit, but this option is not set for every config that enables lockdep. A 4.10 kernel fails to boot with the console output Kernel: Using 8 locked TLB entries for main kernel image. hypervisor_tlb_lock[2000000:0:8000000071c007c3:1]: errors with f Program terminated with these config options CONFIG_LOCKDEP=y CONFIG_LOCK_STAT=y CONFIG_PROVE_LOCKING=n To fix, rename CONFIG_PROVE_LOCKING_SMALL to CONFIG_LOCKDEP_SMALL, and enable this option with CONFIG_LOCKDEP=y so we get the reduced memory usage every time lockdep is turned on. Tested that CONFIG_LOCKDEP_SMALL is set to 'y' if and only if CONFIG_LOCKDEP is set to 'y'. When other lockdep-related config options that select CONFIG_LOCKDEP are enabled (e.g. CONFIG_LOCK_STAT or CONFIG_PROVE_LOCKING), verified that CONFIG_LOCKDEP_SMALL is also enabled.
