[Qemu-devel] [RFC PATCH 19/26] cpu-exec: reset exit flag before calling cpu_exec_nocache

[Pavel Dovgalyuk]

This patch resets icount_decr.u32.high before calling cpu_exec_nocache
when exception is pending. Exception is caused by the first instruction
in the block and it cannot be executed without resetting the flag.
