Vineet Gupta cfd9d70a85 ARCv2: mm: TLB Miss optim: SMP builds can cache pgd pointer in mmu scratch reg ... ARC700 exception (and intr handling) didn't have auto stack switching thus had to rely on stashing a reg temporarily (to free it up) at a known place in memory, allowing to code up the low level stack switching. This however was not re-entrant in SMP which thus had to repurpose the per-cpu MMU SCRATCH DATA register otherwise used to "cache" the task pdg pointer (vs. reading it from mm struct) The newer HS cores do have auto-stack switching and thus even SMP builds can use the MMU SCRATCH reg as originally intended. This patch fixes the restriction to ARC700 SMP builds only Signed-off-by: Vineet Gupta <vgupta@synopsys.com>		2019-10-28 12:12:31 -07:00
