[Qemu-devel] [PATCH v2 2/4] target-i386: Allow interrupt injection after STGI

[Jan Kiszka <jan.kiszka@web.de>]

From: Jan Kiszka <jan.kiszka@siemens.com>

We need to terminate the translation block after STGI so that pending
interrupts can be injected.

This fixes pending NMI injection for Jailhouse which uses "stgi; clgi"
to open a brief injection window.
