Subject: [PULL 10/12] cputlb: Fix tlb_vaddr_to_host
Date: Fri, 25 Oct 2019 10:21:57 -0400	[thread overview]
Message-ID: <20191025142159.12459-11-richard.henderson@linaro.org> (raw)
In-Reply-To: <20191025142159.12459-1-richard.henderson@linaro.org>

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
