Subject: powerpc: Fix 32-bit SMP build
From: Josh Boyer <[email protected]>
commit 6de06f313a65d0ecabf055e708d082002b568866 upstream.
Commit 69e3cea8d5fd526 ("powerpc/smp: Make start_secondary_resume
available to all CPU variants") introduced start_secondary_resume to
misc_32.S, however it uses a 64-bit instruction which is not valid on
32-bit platforms. Use 'stw' instead.
