[Qemu-devel] [PATCH v3 05/15] target-i386: Add comment about do_interrupt_user() next_eip argument |
Date: |
Mon, 13 Jun 2016 18:05:25 +0100 |
From: Peter Maydell <address@hidden>
Add a comment to do_interrupt_user() along the same lines as the
existing one for do_interrupt_all() noting that the next_eip
argument is not used unless is_int is true or intno is EXCP_SYSCALL.
