Does that mean, this patch 1/4 fixes the 32bit issue you guys are still
debugging on the v4 thread? Or does that need more fixing?
I was going to say... This v5 pre-dates figuring out what was wrong with
32bit Xen. v5 1/4 is still susceptible.
Boris: does your Tested-by cover v5 + proposed fix?
Only V5, no extra changes.
And perhaps dropping aliases in xen_alloc_ldt() may be sufficient since
with that done we will only have one mapping so a subsequent fault will
have "correct" cr2 provided by the hypervisor (from your earlier email
it sounded that hypervisor may have been providing incorrect cr2 if
alias exists)
