+Upstream-Status: Pending
+
+The dropbearkey utility built in x32 abi format, when generating ssh
+keys, was getting lost in the infinite loop.
+
+This patch fixes the issue by fixing types of variables and
+parameters of functions used in the code, which were getting
+undesired size, when compiled with the x32 abi toolchain.
+
+2013/05/23
+Received this fix from H J Lu.

+Typdef mp_digit to unsigned long long for MP_64BIT
+
+When GCC is used with MP_64BIT, we should typedef mp_digit to unsigned
+long long instead of unsigned long since for x32, unsigned long is
+32-bit and unsigned long long is 64-bit and it is safe to use unsigned
+long long for 64-bit integer with GCC.

+Cast to mp_digit when updating *rho
+
+There is
+
+int
+mp_montgomery_setup (mp_int * n, mp_digit * rho)
+
+We should cast to mp_digit instead of unsigned long when updating
+*rho since mp_digit may be unsigned long long and unsigned long long
+may be different from unsigned long, like in x32.
