Hi all,

v4 -> v5:
1. change the type of global variable and struct member named "non_strict" from
   "int" to "bool".
2. cancel the unnecessary parameter "strict" of __arm_lpae_unmap which was added
   in v4.
3. change boot option "arm_iommu" to "iommu.non_strict".
4. convert __iommu_dma_unmap to use iommu_unmap_fast()/iommu_tlb_sync(), because
   non-leaf unmaps still need to be synchronous.

Thanks for Robin's review comments.

Since this is 90% of the way there now, I suggest Robin picks up what's here
and incorporates his remaining review comments directly (especially since it
sounded like Zhen Lei hasn't got much free time lately). With that, I can
queue this lot via my smmu branch, which already has some stuff queued
for SMMUv3 and io-pgtable.

Please shout if you have any objections, but I'm keen for this not to
languish on the lists given how close it is!
