powerpc/8xx: Remove PTE_ATOMIC_UPDATES
commit 1bc54c03117b9 ("powerpc: rework 4xx PTE access and TLB miss") introduced non atomic PTE updates and started the work of removing PTE updates in TLB miss handlers, but kept PTE_ATOMIC_UPDATES for the 8xx with the following comment: /* Until my rework is finished, 8xx still needs atomic PTE updates */ commit fe11dc3f9628e ("powerpc/8xx: Update TLB asm so it behaves as linux mm expects") removed all PTE updates done in TLB miss handlers Therefore, atomic PTE updates are not needed anymore for the 8xx Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
