Peter Anvin" , Denys Vlasenko , Andy Lutomirski , Linus Torvalds Subject: [PATCH 0/5] x86/vm86: First round of vm86 cleanups Date: Sat, 11 Jul 2015 01:09:15 -0400 Message-Id: <1436591360-16210-1-git-send-email-brgerst@gmail.com> X-Mailer: git-send-email 2.4.3 Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 1035 Lines: 21 The goal of this set of patches is to change vm86 support to return to userspace with the normal exit paths instead of leaving data on the kernel stack and jumping directly into the exit asm routines. This fixes issues like ptrace and syscall auditing not working with vm86, and makes possible cleanups in the syscall exit work code. arch/x86/entry/entry_32.S | 24 +--- arch/x86/include/asm/processor.h | 11 +- arch/x86/include/asm/thread_info.h | 11 +- arch/x86/include/asm/vm86.h | 36 ++--- arch/x86/kernel/process.c | 7 + arch/x86/kernel/signal.c | 3 + arch/x86/kernel/vm86_32.c | 265 ++++++++++++++++--------------------- arch/x86/mm/fault.c | 4 +- 8 files changed, 152 insertions(+), 209 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
