Subject: [Qemu-devel] [PATCH 4/6] target/mips: Correct the second argument type of cpu_supports_isa()
Date: Mon, 21 Jan 2019 20:08:16 +0100

From: Aleksandar Markovic <address@hidden>

"insn_flags" bitfield was expanded from 32-bit to 64-bit at one moment.
However, this was not reflected at the second argument of the function
cpu_supports_isa(). By chance, this did not create a wrong behavior,
since the second argument was always with the left-most half zero, but
it is still a bug waiting to happen. correct by changint the type of
the second argument to be 64-bit always.
