[Qemu-devel] [PATCH] target-mips: enable access to DSP ASE if implemented

[Petar Jovanovic]

From: Petar Jovanovic <address@hidden>

compute_hflags() will reset DSP h-flags, so MX bit should be initially set
for usermode in cpu_state_reset() if DSP ASE is implemented.
This change will bring back user-mode support for DSP ASE, since one of the
recent changes broke it.
