[PATCH] cputlb: Fix tlb_vaddr_to_host


From: Richard Henderson
Subject: [PATCH] cputlb: Fix tlb_vaddr_to_host
Date: Wed, 23 Oct 2019 11:49:52 -0400

Using uintptr_t instead of target_ulong meant that, for 64-bit guest
and 32-bit host, we truncated the guest address comparator and so may
not hit the tlb when we should.

Fixes: 4811e9095c0
Signed-off-by: Richard Henderson <address@hidden>

Fixes aarch64 emulation on arm32 host, after our recent changes
to tlb probing.
