_tlbia() is a function used only on 603/603e core, ie on CPUs which don't have a hash table. _tlbia() uses the tlbia macro which implements a loop of 1024 tlbie. On the 603/603e core, flushing the entire TLB requires no more than 32 tlbie. Replace tlbia by a loop of 32 tlbie. Signed-off-by: Christophe Leroy <redacted>
Applied to powerpc next, thanks. https://git.kernel.org/powerpc/c/e1347a020b81fe47c80cd277bfaa61295a9482a4 cheers
