Aleksey Gorelov 4031ff3881 [PATCH] fix broken vm86 interrupt/signal handling ... Commit c3ff8ec31c ("[PATCH] i386: Don't miss pending signals returning to user mode after signal processing") meant that vm86 interrupt/signal handling got broken for the case when vm86 is called from kernel space. In this scenario, if signal is pending because of vm86 interrupt, do_notify_resume/do_signal exits immediately due to user_mode() check, without processing any signals. Thus, resume_userspace handler is spinning in a tight loop with signal pending and TIF_SIGPENDING is set. Previously everything worked Ok. No in-tree usage of vm86() from kernel space exists, but I've heard about a number of projects out there which use vm86 calls from kernel, one of them being this, for instance: http://dev.gentoo.org/~spock/projects/vesafb-tng/ The following patch fixes the issue.
