Subject: [Qemu-devel] [PATCH] linux-user: Fix fault address truncation AArch64
Date: Fri, 10 Oct 2014 05:22:55 +0100 [thread overview]
Message-ID: <1412914976-15800-1-git-send-email-amanieu@gmail.com> (raw)
On AArch64 the si_addr field of siginfo_t is truncated to 32 bits
because the fault address passes through an uint32_t variable. This
is fixed by changing the variable to uint64_t.
