and # data segments") tried to initialize various left-over ad-hoc vma's # "properly", but actually made things worse for the temporary vma's used # for TLB flushing. # # vma_init() doesn't actually initialize all of the vma, just a few # fields, so doing something like # # - struct vm_area_struct vma = { .vm_mm = tlb->mm, }; # + struct vm_area_struct vma; # + # + vma_init(&vma, tlb->mm); # # was actually very bad: instead of having a nicely initialized vma with # every field but "vm_mm" zeroed, you'd have an entirely uninitialized vma # with only a couple of fields initialized. And they weren't even fields # that the code in question mostly cared about. # # The flush_tlb_range() function takes a "struct vma" rather than a # "struct mm_struct", because a few architectures actually care about what # kind of range it is - being able to only do an ITLB flush if it's a # range that doesn't have data accesses enabled, for example. And all the # normal users already have the vma for doing the range invalidation. # # But a few people want to call flush_tlb_range() with a range they just # made up, so they also end up using a made-up vma. x86 just has a # special "flush_tlb_mm_range()" function for this, but other # architectures (arm and ia64) do the "use fake vma" thing instead, and # thus got caught up in the vma_init() changes. # # At the same time, the TLB flushing code really doesn't care about most # other fields in the vma, so vma_init() is just unnecessary and # pointless. # # This fixes things by having an explicit "this is just an initializer for # the TLB flush" initializer macro, which is used by the arm/arm64/ia64 # people who mis-use this interface with just a dummy vma. # # Fixes: 2c4541e24c55
