Subject: [PATCH] cputlb: Fix tlb_vaddr_to_host
Date: Wed, 23 Oct 2019 11:49:52 -0400 [thread overview]
Message-ID: <20191023154952.30731-1-richard.henderson@linaro.org> (raw)
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 <richard.henderson@linaro.org>
---
Fixes aarch64 emulation on arm32 host, after our recent changes
to tlb probing.
